Батарейки лучшие: 7 лучших батареек — щелочные, литиевые и аккумуляторные

Какие аккумуляторные батарейки лучше: виды, преимущества, недостатки

Представьте только, сколько разнообразной аппаратуры в одночасье превратятся в очень красивую, но совершенно никчёмную груду электронного хлама, если вдруг исчезнут элементы питания. Все современные плееры, телефоны, фото и видеокамеры, игрушки — все они нуждаются для своей работы в батарейках. Они поддерживают жизнь в наших гаджетах. Делают это незаметно и ненавязчиво, пока хоть капля энергии имеется в них самих. Именно проблема восстановления этой самой энергии и подтолкнула человечество к созданию аккумуляторных батарей.

Виды аккумуляторных батареек, их преимущества и недостатки

Пожалуй, будет очень тяжело назвать точное количество устройств, которые способны функционировать, питаясь от батареек. И число их непрерывно увеличивается. Однако менять каждый раз элементы питания, даже несмотря на то, что стоят они сравнительно недорого, постепенно становится накладно и нерационально.

Вот и приходит на ум мысль об аккумуляторных батареях. Они же не одноразовые! Сели — не беда! Всегда можно подключить к зарядному устройству и восстановить их работоспособность. Да, стоят они дороже, чем простые батарейки, но в итоге выгода становится существенной.

Все аккумуляторные батареи можно разделить на несколько типов. Деление это зависит от того, какие материалы были применены при их изготовлении, а также от их ёмкости и напряжения. Наиболее распространены:

1. На основе никеля и кадмия. Определяются по наличию маркировки Ni-Cd.
2. На основе никеля и металлогидрида. Имеют маркировку Ni-Mh.
3. Батареи литий-ионного типа. Помечаются, как Li-ION.
4. На основе лития и полимеров. Несут на корпусе маркировку Li-Pol.

Основное применение аккумуляторные батареи нашли в различной фото и видеоаппаратуре, беспроводных телефонах, детских игрушках, фонарях и другой технике. Как определить, какой именно аккумулятор подойдёт к определённому устройству? На самом деле, всё довольно просто.

Положительные и отрицательные качества аккумуляторных батарей

Прежде чем определяться с выбором типа аккумулятора, нужно изучить все их «за» и «против».

Ni-Cd

Положительные стороны:

• сохраняет работоспособность при любой температуре;
• имеет низкую стоимость;
• весит немного.

Отрицательные стороны:

• быстрая потеря заряда;
• зарядка возможна лишь после полной разрядки;
• имеет склонность к саморазрядке.

Ni-Mh

Положительные стороны:

• заряд держится долго;
• может работать на высоком напряжении;
• длительный срок эксплуатации.

Отрицательные стороны:

• относительно тяжёлые;
• при температурных скачках теряет заряд;
• стоит дорого.

Li-ION и Li-Pol

Обладают общими положительными и отрицательными свойствами.

Плюсы:

• длительное время держат заряд;
• немного весят.

Отрицательные стороны:

• почти не выпускаются в виде батареек;
• небольшой ресурс перезарядок;
• высокая стоимость.

Какой должна быть хорошая аккумуляторная батарейка: советы по выбору

Если уж так случилось, что настала необходимость приобрести аккумулятор для какого-то гаджета из вашей коллекции, то лучшим выходом будет взять его с собой в магазин, и уж продавец подберёт к нему то, что подойдёт лучше всего. Продавцы тоже люди и частенько ошибаются в выборе товара, даже если рассказать им всё об устройстве, его модели, про все важные параметры. Разные приборы требуют для себя определённого напряжения и конкретного размера батареи.

На верный выбор оказывают влияние целый ряд факторов. Наиболее важный — это температура среды, которая нас окружает. Если предполагается, что на аппаратуру, для которой предназначаются батарейки, будут воздействовать высокие или низкие температуры, то оптимальным выбором станет аккумулятор на основе никель–кадмия. Если температура роли не играет, то лучше использовать батареи Ni-Mh.

Немаловажный фактор и длительность работы аккумулятора. Если нужно, чтобы устройство функционировало длительное время без необходимости замены батарей, значит, стоит обратить внимание на никель–металлогидридные аккумуляторы. Из всех остальных именно они обладают такими характеристиками. Оптимальный выбор для фотовспышки.

Следующее, на что следует обращать внимание — какое подаётся напряжение. На данный случай определённых рекомендаций не существует. Тут нужно смотреть на то, что запрашивает устройство. Это можно вычитать в инструкции пользователя. Не торопитесь покупать аккумулятор только для того, чтобы он был. Изучите сперва документацию, хотя в среднем напряжение всегда одинаково.

Далее, что немаловажно, – это разновидность устройства, для которого и приобретается аккумулятор. Если это телефон, мобильный или радио, то выбирайте батареи под маркировкой Li-ION. Они производятся в особых формах, которые не имеют ничего общего с «пальчиковыми» или «мизинчиковыми» батарейками.

Очень важно обратить внимание на ёмкость аккумулятора. Он указывается на корпусе и обозначается mAh. Чем больше значение перед этими буквами, тем дольше батарея будет держать заряд, но и заряжать её нужно тоже дольше.

То, что вами были приобретены нужные аккумуляторы, ещё далеко не всё. Заряжать-то их как? Для них потребуется специальное зарядное устройство. Порой «зарядник» идёт в комплекте с аккумуляторами, а частенько и отдельно искать нужно.

Если купленные вами аккумуляторы относятся к никель-кадмиевому типу, то зарядное устройство должно иметь возможность полностью разряжать батарею. Ведь, как мы помним, этот тип нельзя заряжать, пока в них имеется ещё заряд.

Для никель-металлогидридных батарей зарядное устройство должно быть от той же фирмы, что и они сами.

Ну а к литий-ионным либо литий-полимерным батареям, лучше брать ЗУ универсального типа. Определённо не промахнётесь с напряжением и разъёмами.

Лучшие аккумуляторы: рейтинг

Аккумуляторные батареи выпускаются многими производителями. Порой очень трудно определиться, товар какой марки выбрать. Среди всего многообразия можно выделить наиболее популярные модели и фирмы:

1. GP Rechargeable.
2. Panasonic Eneloop PRO.
3. Duracell Recharge TURBO.
4. Energizer.
5. Varta.
6. Ergolux Rechargeable batteries.
7. Robiton AAA R03 Micro.

У каждого из представленных вариантов есть собственные плюсы и минусы.

(Buyer’s Guide) 90006 90119 90002 90523 90524 90003 90002 There are tons of factors you need to put into consideration before you make the buy-in to decide which batteries would be adequate for you, and which one to choose. 90003 90002 This task can be extremely time consuming and somewhat painful. Besides, there’s a high chance you might end up making a wrong purchase even after night-long research. However, this article has gone through enough research to narrow down the important keynotes and to help you in your endeavor.90003 90002 Let’s have a look at the most important factors you need to consider so that you can have the best AA batteries. 90003 90002 90005 Durability 90006 90003 90002 How long does a AA battery last? This should be your primary concern while purchasing your desired battery for your device. A long-lasting battery goes a long way. 90003 90002 There are three aspects of durability that should be taken into account; run time, shelf life, and cycle life; 90003 90136 90137 Run time refers to how long a battery or battery pack will run on single-use.90138 90137 Shelf life means under specified conditions, the duration for which a battery or cell can be stored and still retain its performance. 90138 90137 Cycle life refers to how many complete charges and discharges a rechargeable battery can be used before it can no longer hold a charge. 90138 90147 90002 90005 Devices 90006 90003 90002 The device falls into two categories: 90003 90136 90137 High drain device -These devices require more power at a steady rate to function (eg, digital camera, photoflash) 90138 90137 Low drain device — These devices require a little amount of power, and that too in bursts (e.g., remote control, alarm clock) 90138 90147 90002 Based on your device, you should purchase accordingly. 90003 90002 90005 Disposal or Rechargeable 90006 90003 90002 To fully understand which category of batteries is suitable for you, you need to dig a little deeper into a few things. So shall we? Rechargeable batteries are usually more expensive since they can be recharged and reused many times over after the initial purchase. 90003 90002 However, disposal batteries last longer after their initial purchase.But get this; once they are dead, they are gone for good. If you are conscious about your environment and worried that disposable batteries might garner more damage to our surroundings, then you might want to note it down. 90003 90002 So, from an environmental standpoint, rechargeable batteries are much better. 90003 90002 Although it might seem like a no-brainer and you might already be in favor of rechargeable batteries, you should consider that they cost a lot more than disposable batteries.90003 90002 Also, disposable batteries are better equipped for low drain devices as they require a very low amount of power. Ultimately, the decision falls upon you and your preference. 90003 90002 90005 The Right Type 90006 90003 90002 There are several types of batteries out there, but to find the right one you need to understand the difference between Alkaline from Lithium and NiMH from Lithium-ion from NiCd. 90003 90136 90137 90005 For Disposable Batteries: 90006 90138 90147 90002 90005 Lithium — 90006 Fastest growing battery system.Lithium is used where high-energy density and lightweight is of prime importance. They are used more in high drain devices. 90003 90002 Lithium batteries currently hold the title for longest life for the disposable category. They also work very well in extreme temperatures. But these batteries are more expensive than alkaline. 90003 90002 90005 Alkaline — 90006 They can provide a high current output; they have good high and low-temperature performance. Low drain devices are better suited to these batteries.Their price is reasonable, and these are available worldwide. 90003 90002 After usage, they are usually dumped into landfills, which is bad for the environment. 90003 90136 90137 90005 For Rechargeable Batteries: 90006 90138 90147 90002 90005 Nickel Metal Hydrides 90006 — These are commonly known as the hybrids of batteries. Nickel metal hydrides are ready for usage as soon as you open the packaging. 90003 90002 They have very low self-discharge, and they work best for both low and high drain devices.These batteries are reasonably expensive, but their energy quality declines by 10% to 15% after few hundred recharge. 90003 90002 90005 Lithium-ion 90006 — It is delicate and requires a protection circuit to assure safety. They are used for notebook computers and cellular phones and has the lowest self-discharge rate among all the batteries. Lithium-ion batteries can be recharged a lot of times. 90003 90002 They are recyclable but, however, subject to aging, even if left idle. These batteries are also expensive.90003 90002 90005 Nickel Cadmium 90006 — NiCd batteries are fairly cheap to produce; they are also relatively inexpensive to buy and are used for many different types of devices. They can be easily stored and does not get damaged under most normal circumstances. These batteries are simple and fast to charge. 90003 90002 Temperature fluctuating does not bother NiCd. They also have a relatively low density but are not as powerful as some other batteries. These batteries often self-discharge. 90003 90116 90005 Benefits of Using AA Batteries 90006 90119 90002 Keep your devices running with a supply of fresh AA batteries.AA, single-cell batteries have a standard size regardless of the types of electrolytes used.

Huawei Mate Xs 90010 90011 90002 90009 Capacity: 4,500mAh | Official life: not stated | Charging power: 55W wired 90010 90003 90002 90017 90003 90002 The Huawei Mate Xs is probably a phone few will be considering.After all, it’s a foldable phone, and like all foldable phones it’s very expensive. But it also has strong battery life, which is all the more impressive when you consider its massive 8-inch screen (which can be folded down into a 6.6-inch size). 90003 90002 The battery is not even all that enormous at 4,500mAh. That’s large for a conventional phone, but not even as big as some of the others on this list, yet Huawei has worked some magic to ensure this comfortably lasts at least a day of moderate use.90003 90002 But this is not a phone you’ll be buying for its battery as such. The appeal really does mostly lie in its screen, which allows the Huawei Mate Xs to fill the role of both a phone and a tablet — and if you consider it like that, it’s actually not so unaffordable, since you will not need to also buy a tablet alongside it. 90003 90002 A high-end Kirin 990 chipset, a quad-lens camera, 512GB of storage, and a stylish design ensure that this more than does the job of both a phone and tablet too, just be aware that while it runs Android there’s no Google Play Store, so you’ll have to use third-party alternatives for your apps and games.90003 90002 90009 Read our Huawei Mate Xs review 90010 90003 90008 90009 9. iPhone 11 Pro Max 90010 90011 90002 90009 Capacity: 3,969mAh | Official life: 20 hours of video playback | Charging power: 18W wired / Qi wireless 90010 90003 90002 90040 90003 90002 The iPhone 11 Pro Max is the best iPhone available at the time of writing, which is all many people will need to hear before making their buying decision, but it also sports the best battery life of any current iPhone.90003 90002 It has a 3,969mAh battery, which is marginally smaller than the juice packs of most phones in this list, but Apple makes it go a long way, delivering up to five hours more life than its predecessor, the iPhone XS Max. 90003 90002 That in practice means it’s easy to get over a day from this phone and conservative users could get two days at a push. 90003 90002 Of course, being the best iPhone there’s also plenty of other stuff to like here. The iPhone 11 Pro Max has tons of power, thanks to Apple’s A13 Bionic chipset, which is arguably the best one used in any 2019 handset and even a rival for the best of 2020.90003 90002 It also has a great 6.5-inch 1242 x 2688 screen, brilliant triple-lens cameras, advanced facial recognition, and of course iOS, making it a top choice for anyone who prefers Apple’s smartphone operating system to Google’s. 90003 90008 90009 8. OnePlus 8 90010 90011 90002 90009 Capacity: 4,300mAh | Official life: a full day | Charging power: 30W wired 90010 90003 90002 90061 90003 90002 The OnePlus 8 is not even the OnePlus phone with the best battery life — you’ll find that below, but with its 4,300mAh juice pack it certainly impresses, no doubt helped by its 6.55-inch screen, which at 1080 x 2400 is sharp but not packing as many pixels as some phones, so should be lighter on the battery. 90003 90002 With average use this should see you beyond a day, but it will not stretch to two. That puts it in the same category as a number of phones with above average battery life. There’s also 30W fast charging, so you can juice it up quickly, but there’s no wireless charging. 90003 90002 Beyond the battery, other reasons to recommend the OnePlus 8 include its top-end power, with a Snapdragon 865 chipset at its heart, and its support for 5G.The phone also packs a capable triple-lens camera, a stylish design, up to 12GB of RAM, and up to 256GB of storage. 90003 90008 90009 7. Samsung Galaxy A70 90010 90011 90002 90009 Capacity: 4,500mAh | Official life: 24 hours of video playback | Charging power: 25W wired 90010 90003 90002 90078 90003 90002 As part of Samsung’s slightly confusing A range, the Galaxy A70 is a phone that’s easy to overlook, but that would be a mistake, especially if you want great battery life from a mid-range handset.90003 90002 It has a 4,500mAh battery, allowing it to just about stretch to two days of life if you’re a fairly light user. And impressively it also supports fast charging, which is something you do not always get outside the top-end. 90003 90002 Other highlights of the Samsung Galaxy A70 include a big 6.7-inch 1080 x 2400 screen, a triple-lens rear camera, an in-screen fingerprint scanner and a fairly high-end design. 90003 90002 The power is mid-range, but in most other ways this phone is not far off a flagship, and it has most flagships beat for battery life.90003 90002 90009 Read our Samsung Galaxy A70 review 90010 90003 90008 90009 6. Samsung Galaxy S20 Plus 90010 90011 90002 90009 Capacity: 4,500mAh | Official life: all day | Charging power: 25W wired / 15W wireless 90010 90003 90002 90101 90003 90002 The Samsung Galaxy S20 Plus is a phone that should need no introduction, after all it’s part of the most high-profile Android range, and it’s the second best of that range, both in terms of battery and other things. 90003 90002 It has a 4,500mAh battery, which is enough to beat out most but not all other phones, and battery life generally follows suit.You can get close to two days of life with frugal use, but if you’re a heavy user, or make a lot of use of the 120Hz refresh rate (which can be disabled) or 5G, then life drops, but you should still comfortably get a day. 90003 90002 It’s a shame that two of the key features hit the battery life so much, but at least you have the choice of whether to use them or not, and the S20 Plus does support both fast and wireless charging (as well as reverse wireless charging ) so you have plenty of powering options.90003 90002 You also get a great 6.7-inch 1440 x 3200 screen, top-tier power, a brilliant quad-lens camera and most other flagship bells and whistles. 90003 90008 90009 5. Huawei P40 Pro 90010 90011 90002 90009 Capacity: 4,200mAh | Official life: not stated | Charging power: 40W wired / 27W wireless 90010 90003 90002 90120 90003 90002 The Huawei P40 Pro is the latest and greatest Huawei flagship at the time of writing, and on the battery front you’re looking at a 4,200mAh juice pack, which is not as big as some phones in this list, but in our tests we found it could realistically reach two days of life, which is an impressive figure.90003 90002 The Huawei P40 Pro also supports fast charging, with or without wires, so it juices up quickly, and there’s 27W reverse wireless charging too, so it works as a capable charging pad for other devices. 90003 90002 Beyond the battery you get a 6.58-inch 1200 x 2640 screen, a powerful Kirin 990 chipset, a great quad-lens camera, and a sumptuous design. As with other recent Huawei handsets though, there’s no Google apps or services here, which is something to bear in mind if you’re considering a purchase.90003 90002 90009 Read our Huawei P40 Pro review 90010 90003 90008 90009 4. OnePlus 8 Pro 90010 90011 90002 90009 Capacity: 4,510mAh | Official life: not stated | Charging power: 30W wired / 30W wireless 90010 90003 90002 90141 90003 90002 The OnePlus 8 Pro is the first OnePlus phone to support wireless charging, and it does so at 30W speeds, so you can juice it up fast even without a cable. 90003 90002 That’s good, because at 4,510mAh the OnePlus 8 Pro can store a lot of juice, and that allows it to last well over a day even if you push it hard.With lighter use even a second day of life is feasible. 90003 90002 The OnePlus 8 Pro also excels in a number of other areas, so it’s a great buy whatever you want from your phone. It has a sharp 6.78-inch screen with a slick 120Hz refresh rate, a quad-lens camera, top-end power provided by a Snapdragon 865 chipset, up to 12GB of RAM, water resistance (another first for a OnePlus phone), and a stylish design. 90003 90008 90009 3. Samsung Galaxy A90 5G 90010 90011 90002 90009 Capacity: 4,500mAh | Official life: 24 hours of video playback | Charging power: 25W wired 90010 90003 90002 90158 90003 90002 The Samsung Galaxy A90 5G is not quite a match for the Galaxy S20 or S20 Plus in most ways, but it has them beat when it comes to battery life, as it has a big 4,500mAh battery, paired with a less sharp 1080 x 2400 screen, so it’s not as power-hungry.90003 90002 The Galaxy A90 5G can therefore last up to around two days between charges if you’re careful — though that figure is likely to go down if you’re using 5G. It does not support wireless charging, but does support 25W fast charging. 90003 90002 The Samsung Galaxy A90 5G also has a high — but not quite top — end Snapdragon 855 chipset, plus up to 8GB of RAM, and a triple-lens camera, so it’s slightly lower end than some phones in this list, but has most beat for battery. 90003 90008 90009 2.Samsung Galaxy S20 Ultra 90010 90011 90002 90009 Capacity: 5,000mAh | Official life: all day | Charging power: 45W wired / 15W wireless 90010 90003 90002 90175 90003 90002 The Samsung Galaxy S20 Ultra is the ultimate, no-compromise flagship, and that includes the battery, which is an enormous 5,000mAh. 90003 90002 That gives this phone a whole lot of life, though using advanced features like its 120Hz screen and 5G can lessen this somewhat. 90003 90002 Still, most users will be able to go a long time between charges, and with 45W wired or 15W wireless charging you can power back up quickly.You can also make the most of that substantial juice pack by using the Galaxy S20 Ultra as a wireless charging mat to juice up other devices. 90003 90002 Elsewhere, the Samsung Galaxy S20 Ultra has top-end power, a quad-lens camera led by a remarkable 108MP sensor, a massive 6.9-inch 1440 x 3200 screen, and just about everything else you might reasonably want from a phone. 90003 90002 90009 Read our Samsung Galaxy S20 Ultra review 90010 90003 90002 {widget} 90003 90008 90009 1. Moto G8 Power 90010 90011 90002 90009 Capacity: 5,000mAh | Official life: Up to three days | Charging power: 15W wired 90010 90003 90002 90200 90003 90002 The Moto G8 Power is not one of the most exciting phones on this list, as it’s lower end than most.But that means it’s cheaper, and it has them all beat for battery life. 90003 90002 It has a 5,000mAh battery, matching the largest other options on this list, but paired with a less powerful phone, so it lasts longer. 90003 90002 Specifically, the Moto G8 Power should be able to get you through two days or more between charges — Motorola claims it can actually manage up to three, which is a remarkably long time. It’s not the fastest at charging, and there’s no wireless charging, but its longevity more than makes up for that.90003 90002 Other specs include a 6.4-inch 1080 x 2300 screen, a mid-range Snapdragon 665 chipset, 4GB of RAM, and a quad-lens camera, so not a bad assortment of specs, especially considering the price, but it’s the battery you ‘ll really be buying this phone for. 90003 90008 90009 Conclusion 90010 90011 90002 So there you have it, ten of the longest lasting phones around. In tenth place we have an unusual choice in the form of the foldable Huawei Mate Xs, then in ninth it’s the longest lasting iPhone: the iPhone 11 Pro Max.90003 90002 The OnePlus 8 is an affordable flagship in eighth place, then the even more affordable Samsung Galaxy A70 takes seventh. Next, there’s the top-end Samsung Galaxy S20 Plus, Huawei P40 Pro and OnePlus 8 Pro in sixth, fifth and fourth respectively, 90003 90002 The Samsung Galaxy A90 5G is one of the cheapest ways to get 5G, and it also has brilliant battery life, taking third place in our list, followed by the stunning Samsung Galaxy S20 Ultra in second. That phone will cost you a lot, but the Moto G8 Power will not, and that’s the best choice overall for battery life.90003 90002 So there should be something for everyone here, but any of these phones will last you a long time between charges. 90003 .90000 Best Car Battery (Review & Buying Guide) in 2020 90001 90002 90003 Home 90004 90003 Сategories 90006 90003 Accessories 90006 90003 Interior Accessories 90004 90003 Exterior Accessories 90004 90003 Toys 90004 90015 90004 90003 Cleaning & Detailing 90004 90003 Electronics 90006 90003 Audio 90004 90015 90004 90003 Engine & Performance 90004 90003 Tools 90004 90003 Tires & Wheels 90004 90003 Motorcycles & Bikes 90004 90003 Home Care 90004 90003 RV Campers 90004 90003 Off-Road Vehicles 90004 90003 Warranties 90006 90003 Extended Warranties 90004 90003 Factory Warranties 90004 90015 90004 90015 90004 90003 Blog 90004 90003 Tools 90006 90003 Tire Size Calculator 90004 90003 Wheel & Tire Finder 90004 90015 90004 90003 About Us 90004 90003 Contact 90004 90015 90002 90003 90066 90004 90003 90066 90004 90003 90066 90004 90003 90066 90004 90015 90078.90000 Best rechargeable batteries — The Prepared 90001 90002 This is an easy win for any prepper: remove the common alkaline batteries found around your house in remotes, lights, clocks, and other gear, set them aside in a cool place for storage, and move to rechargeables. Pick up one or more high-quality battery chargers, and you’re set. 90003 90002 Not all rechargeables work the same way. Experts recommend the NiMH LSD battery chemistry over the better-known lithium-ion style whenever possible.But NiMH only comes in the AA family, so if you’ve got 18650s, CR123As, or other uncommon sizes, be sure to buy Li-Ion with cell protection and a micro-USB charging port built in. 90003 90002 90007 Reviews 90008: Portable battery packs (non-removable battery versions) and disposable batteries. 90003 90002 90007 More 90008: Not sure about battery types and when you’d use which one and why for emergency preparedness? Check out the beginner’s guide to batteries for preppers. 90003 90014 AA-family rechargeable batteries 90015 90002 Our Pick 90003 90018 90019 Best for most people: 90020 90019 Panasonic Eneloop 90020 90002 The gold standard of long-lifespan NiMH LSD rechargeable batteries, and ideal for everything from daily use to long-term grid-down prepping.Accept no substitutes. (No, seriously, these are so popular that they’re widely counterfeited, so be careful out there.) 90003 90002 The best rechargeable batteries for preppers are 90007 Panasonic Eneloop AA NiMH LSD 2100-cycle 90008 90007 batteries 90008 (AA) and 90007 AAA 8-packs 90008. These Eneloops hold at least 70% of their charge for 10 years when sitting on a shelf, making them perfect for prepping. 90003 90002 The low self-discharge (LSD) variants of the market-leading Eneloop NiMH batteries combine an insanely high number of charge / discharge cycles without sacrificing too much capacity.The 2100-cycle Eneloops are the lowest capacity (2000mAh) but longest lifespan batteries in the Eneloop family — there’s often a tradeoff between how much energy a NiMH battery can hold at once vs. how many times that battery can be recharged. Preppers should usually go with the higher charge cycle variants, which also happen to be cheaper than their higher-capacity siblings. 90003 90002 That’s part of the reason why there are not many contenders to pick from. Even when you set aside the counterfeits and low-quality products, there just are not many choices that offer the higher lifespan variant.Quality competitors, like PowerEX, only offer choices at the higher capacity / lower cycle count tier. 90003 90002 Get Started 90003 90039 90019 Great starter pack: 90020 90019 Panasonic Eneloop Super Power Pack 90020 90002 This selection of market-leading Eneloop batteries and adapters will let you replace all the alkaline batteries in your house with long-term use rechargeables that’ll also serve as preps.90003 90046 90019 If you have many C / D: 90020 90019 Panasonic Eneloop Plus Pack 90020 90002 If you need more C and D adapters in your starter kit, you can get started with the Plus Pack and supplement with an additional pack of AAs. 90003 90002 If you’re just getting started with Eneloops and have a wide range of battery-powered gear, we recommend the 90007 Eneloop Super Power Pack 90008 as the best bang for your buck.It comes with 12 AA batteries, 4 AAA batteries, two AA-to-C adapters, two AA-to-D adapters, a smart battery charger, and a plastic case. You can replace decades worth of disposable alkaline batteries with just this one kit. If you have a lot of gear that takes C and D batteries, you should go with the 90007 Plus Power Pack 90008 — it has half the number of AA batteries (six), and twice the number of C and D adapters as the Super Power Pack, and is a few dollars cheaper. 90003 90002 When you’re moving all your daily-use batteries over from alkalines to Eneloops, you’ll want to keep a supply of pre-charged replacement batteries on-hand in the appropriate sizes.That way, when a rechargeable gets low, you can immediately replace it with one of the charged batteries you have on standby. You’ll then recharge the low battery and have it on standby for when the next battery runs down. 90003 90002 Given the need for pre-charged standby batteries, you’ll probably need to supplement the packs above with more AA and AAA. As you build up this spare battery stash, be sure to stick with the regular 2100-cycle Eneloops, and avoid the more expensive batteries with a lower cycle count.90003 90002 Also Great 90003 90065 90019 Eneloop alternative: 90020 90019 Fujitusu Rechargeable Batteries 90020 90002 Though they’re harder to come by, the Fujitsu batteries are just as excellent as the Eneloops, and less likely to be counterfeited. 90003 90002 Equally as good as the Eneloops — in fact, probably identical, since they’re from the same factory — are 90007 Fujitsu 2100-cycle NiMH LSD batteries 90008.The Fujitsu NiMH LSD batteries are hard to find, which is why they are not our main pick, but they have two distinct advantages over the Eneloops: price and brand safety. Specifically, the Fujitsu batteries are cheaper than their Eneloop equivalents, and because they’re so rare they’re far less likely to be counterfeited. So if you can find Fujitsu NiMH LSDs in stock, snap them up. 90003 90002 For devices that take larger C or D cells, you have two rechargeable options: 90003 90078 90079 If it’s a 90007 critical prep 90008 or a 90007 daily use item 90008, consider shelling out for high-quality NiMH LSD C or D cells.The best rechargeable C and D cells are the 90007 PowerEX C 2-pack 90008, or the 90007 PowerEX D 2-pack 90008 90088 90079 For non-essential and / or very 90007 infrequently used devices 90008, you can pair a higher-capacity, lower-cycle AA rechargeable with a C or D adapter. That way, you can raid that device for AAs in a pinch. The best higher-capacity NiMH LSDs for preppers are the 500-cycle, 2700mAh 90007 PowerEX Pro AAs 90008, which at roughly $ 25 for an 8-pack are just two-thirds the price of the more popular 500-cycle, 2500mAh Eneloop Pro AAs .90088 90095 90002 PowerEX batteries come from the same Japanese factory as Eneloops, and the brand is niche enough that they’re far less likely to be counterfeited on retail sites like Amazon, so buy with confidence. 90003 90002 We normally try to offer a budget choice, but in this case it’s better to save up for the main choices. Unfortunately, in this market, the popular budget options — Amazon Basics and IKEA LADDA — are slightly higher capacity but have less than half the lifespan of the Eneloop 2100s.It’s also the case that Amazon sources many of their batteries from different factories in China, so quality is all over the map. 90003 90002 Ultimately, preppers should invest in fewer batteries that will last a lot longer, rather than going for quantity over quality. If you have to bug out, you’ll wish you had a small stash of Eneloops rather than a large pile of budget rechargeables or alkalines. 90003 90002 Best 9V 90003 90104 90019 Best for most: 90020 90019 EBL 9V 90020 90002 Our top pick does not come in 9V, but the well-reviewed EBLs do.Inexpensive, safe, and easy to recharge, consider these in any application where you need 9V and do not want to spring for expensive lithium disposable batteries. 90003 90111 90019 Upgrade: 90020 90019 ANSMANN 9V 90020 90002 These premium batteries hold 50mAh more than the EBLs. You pay for that extra capacity, but in some cases it’s worth it.90003 90002 The Eneloops do not come in 9V, so for that size we like the 90007 EBL 9V battery 4-pack 90008. The EBLs are relatively inexpensive and get great reviews. Or, if you want an upgrade in capacity from the 250mAh on the EBLs, you can pick up the 90007 ANSMANN 9V NiMH LSD 300mAh 9V. 90008 But the ANSMANNs are twice the price for only a 20 percent storage boost. You’ll also take a slight hit on the lifespan 1000 cycles for the ANSMANNs vs.1200 cycles for the EBLs. But if you need the extra capacity then this is not a bad tradeoff. 90003 90014 Non-AA sizes and rechargeable lithium-ion batteries 90015 90002 Unfortunately, the better NiMH LSD chemistry is not available in form factors outside of the AA family (AAA, C, D, 9V). So if you have a flashlight, firearm optic, or other gear that takes an unusual battery, you have two choices: 90003 90078 90079 Use lithium-ion rechargeable tech instead 90088 90079 Do not use rechargeables in that gear 90088 90095 90002 We recommend picking up some of the best disposable batteries for gear that you rarely use (eg.a flashlight in your emergency bag that turns on once a year) and / or for gear that uses button- or coin-style batteries (eg. CR2032s used in popular rifle optics). 90003 90002 Quality disposables are better for rarely-used gear because they hold their charge while sitting on a shelf for much longer than a rechargeable. For the unusual and flat battery sizes, it’s just not worth recharging those small, infrequently used batteries, so do not bother. 90003 90002 For daily-use gear or products which take cylindrical batteries that kinda look like they’re in the AA family (but are not), you’ll want to buy protected Lithium-Ion batteries with a built-in USB charging port.90003 90002 Our Picks 90003 90142 90019 Rechargeable CR123A: 90020 90019 Fenix ​​16340 90020 90002 This rechargeable battery from Fenix ​​includes its own charging and overcharge protection circuitry, along with a USB port for power input. Can be used in place of any CR123A. 90003 90149 90019 Trusted value: 90020 90019 Fenix ​​18650 90020 90002 This Fenix ​​battery is popular with flashlight enthusiasts.Features built-in charging port and overcharge protection. The 18650 scene is dangerously rife with fraud and poor quality, so play it safe and buy the best. 90003 90002 The best rechargeable CR123A battery for preppers is the $ 9 90007 Fenix ​​16340 700mAh. 90008 This well-reviewed battery from a quality brand meets our core criteria and will be right at home in a flashlight, camera, or other device, giving you about 500 cycles of lifespan with proper care.There are products from other brands that are similar to the Fenix ​​16340, but they’re both more expensive and have less capacity, making the Fenix ​​a no-brainer. 90003 90002 Also from Fenix ​​is ​​the $ 23 90007 Fenix ​​18650 with built-in USB port 90008. The 3500mAh capacity is better than many competitors of the same size or price range. We urge you not to go cheap on 18650s because the market is currently full of scammers and junk — only buy quality from a trusted source. Otherwise, you run the risk of a Li-Ion fire or just plain poor performance.90003 90002 Our Picks 90003 90166 90019 Premium: 90020 90019 Fenix ​​14500 90020 90002 This Li-Ion rechargeable AA battery is suitable for high-drain devices, like tactical lights, that need a full 1.5V of output. Built-in USB charging port and overcharge protection make this a winner. 90003 90173 90019 Budget: 90020 90019 Blackube AA 90020 90002 A bit cheaper than the Fenix ​​and a bit less capacity, these batteries have all the same great features as our top pick.90003 90002 If you’re nervous about your NiMH battery supply’s need for an external charger as a single point of failure, it’s possible to get AA-sized rechargeable batteries in a Li-Ion format with a built-in USB charger, thereby eliminating the dependency on an external charger. Li-Ion rechargeables have far shorter lifespans and shelf lives than NiMH LSD AAs, and much smaller capacities. But if you take care to properly store and maintain them, they can work in the right role as a rechargeable backup battery.90003 90002 The best USB-rechargeable AA Li-Ion batteries for preppers are the $ 10 90007 Fenix ​​14500s 90008 because, other than being from a quality brand, their 1600mAh capacity is ~ 100mAh larger than competitors. 90003 90002 Also great (and about a dollar cheaper per battery) is the $ 25 four-pack of 90007 Blackube AA USB-rechargeable batteries 90008. These well-reviewed batteries have 1500mAh of capacity and will recharge in just 1.5 hours via the built-in USB port. 90003 90002 90007 Warning 90008: When using Li-Ion rechargeable batteries in place of lithium primary batteries, be sure to head all warnings about differences in voltage, charge / discharge patterns, and safe storage.90003 90019 How to avoid fake batteries 90020 90002 There’s a lot of junk in this market. The best way to ensure you get the best batteries is to exclusively buy Japanese. 90003 90002 Through quirks of history and corporate consolidation, all of the high-quality NiMH LSD batteries in the world come out of a single factory in Japan — regardless of the brand they’re sold under. 90003 90002 Eneloops and Fujitsus, as top-tier brands in the same factory, are basically identical because they both set high standards and receive the cream of the production crop.Plus they’re big clients the factory does not want to upset. 90003 90002 But, as is true for bushcraft hatchets, survival axes, and many other types of gear, products that come from the same factory yet are sold under different brands are not necessarily equivalent in quality. That one factory will try to make more money by selling the leftovers to and / or doing production runs with lower quality standards for other brands willing to sell an inferior product at a lower price point. 90003 90002 That leads some battery reviewers and forum enthusiasts to always be on the lookout for ways to score the most expensive Japanese batteries for less money under an alternate label.90003 90002 Scammers know this, too. They try to exploit that bargain hunting and consumer confusion with inferior but attractively-priced alternatives. 90003 90002 This is definitely true of Japanese-made NiMH LSD batteries, so to be safe you should exclusively stick with Eneloop and Fujitsu brands. Leave the IKEA and Amazon Basics batteries to the forum geeks. 90003 90002 Tips: 90003 90212 90079 Buy Japanese-made batteries only from major, trusted retailers like Amazon, Target, Best Buy, Battery Junction, or smaller authorized Panasonic dealers (e.g. Mouser and Digikey). 90088 90079 When buying on Amazon, only buy when it’s «shipped from and sold by Amazon», not a third-party vendor. 90088 90079 Be particularly careful when buying Eneloops. As the most popular and expensive choice, they’ve attracted the most counterfeits. 90088 90079 Panasonic has the rights to sell Eneloops in the US market, and they do it well. But when outside the US market, Panasonic will mix in some lower-quality Chinese-made batteries — so you will not necessarily know what you’re getting if you do not go to extra lengths to explicitly source Japanese batteries.90088 90079 Only buy Chinese batteries if you have good reason to trust the source. 90088 90223 90014 How we picked the best rechargeable batteries for preppers 90015 90002 Because batteries are one of those communities that have a core group of super-knowledgeable enthusiasts, there are a number of extremely high-quality, well-researched battery guides out there on the web. We relied heavily on their expertise and detailed testing. 90003 90002 But these guides are all aimed at regular consumer electronics and daily-life scenarios.They assume you’ll always have access to new batteries and a functioning electric grid, for example. 90003 90002 Emergency preparedness has special needs. So we picked the winners based on: 90003 90078 90079 Number of charge / discharge cycles, that way a single battery can be used repeatedly for the longest possible time in a long-term crisis. 90088 90079 How well they retain a charge when sitting in storage, so they’re good to go whenever you rarely and suddenly need them. 90088 90079 No special maintenance needs for long-term storage, like keeping the batteries cold or topping them off.90088 90079 Available in common sizes and able to be fit into less common sizes using adapters. 90088 90095 90002 NiMH LSD AA / AAA batteries were the clear winner here, nailing all of the above prepper-specific criteria. There is not even a close second. 90003 90002 The first criterion above is the big one that distinguishes our approach from the other consumer-grade battery guides. For normal consumers, it often makes sense to take a major hit on the number of times you can recharge them in order to get more capacity.But for preppers who are investing in an emergency battery supply to last for years, lifespan is key, and the normal NiMH LSD capacity / lifespan tradeoff is not even close to worth it. 90003 90002 The only minor downside to the NiMH LSD AA / AAA is that the voltage output is 1.2V, whereas standard alkaline AAs have a 1.5V output. But alkaline AAs only give a full 1.5V when they’re fresh, and they quickly drop down to a lower voltage after, so this is not an issue for most AA-powered devices because they’re engineer to handle under 1.5V anyway. 90003 90019 Why you should trust us 90020 90250 90002 Jon Stokes is the co-founder of Ars Technica, former editor of WIRED, founding editor of AllOutdoor, and contributing editor to The Firearm Blog.
