These batteries have a lot going for them: they come fully charged (like alkaline batteries), and they can hold their charge over many months (unlike regular Ni-MH rechargeables). The charge times are as follows: AA Eneloops charge in 230 minutes, and AAA Eneloops charge in 135 minutes. How about some good battery chargers to go with these batteries?A The chargers featured below are some of the smartest out there — they have built-in protection to prevent overcharging or undercharging. The drawback is that the single-status LCD panel a long programming sequence makes it a bit difficult to use for multiple cells. Maha’s chargers can restore batteries to their optimal performance level by repeatedly charging and discharging them. Does ‘Eneloop’ supply rechargeable 9volt pps batteries and the appropriate charger?
If I use an item once per week(like a beard trimmer) for 10 minutes, should I use rechargeable AA Nimh LSD batteries(like Eneloop, Eneloop Pro or Energizers)?
Do I have to completely run out a rechargeable battery before I can charge it again, or can I charge it when I want? I usually do buy packs of 4 and run several cycles in an old fashioned flash light just breaking them in. Personally I would go with the Maha PowerEx a€?Ultimate Professionala€? Charger, It will charge lots of kind of batteries for any use. Battery Polarity Reversal Protection – Prevents Charger damage and operation in case a battery is inserted into the MH-C808M backwards. Alkaline battery Protection – Automatically recognizes an Alkaline battery and Prevents Charger operation and damage.
Yes, the newer NiMh batteries have a longer shelf life, and are generally more reliable than the older kinds.
I use rechargeable batteries in every device in my home (requiring batteries), and I don’t have any issues. I use Eneloops with my XBox 360 Wireless controller hooked up to my PC, no problems whatsoever. If the eneloop are the best batteries why doesn’t Panasonic have it’s own top rated charger? Over time I’ve seen a number of battery manufacturers recommend using their chargers only with the batteries they produce. What do you think about SunLabz 2800 mAh AA batteries and their associated smart battery recharging counterpart? I fly RC Helicopter’s almost daily and I have tried many generic rechargeable batteries but nothing compared to the Eneloop.
I just can’t say enough positive things about Eneloop rechargeable batteries but try them for yourself. Rechargeable batteries are better and cheaper than you remember, holding a charge for years and costing less than a nickel per charge over their life cycle. Our new pick for the best rechargeable batteries are the Energizer Recharger Power Plus, which proved their worth in testing and are widely available at a fair price. Our pick was discontinued at the end of 2014, but we're finishing up a new round of testing.
Better explains the difference between the normal 2000mAh Eneloop 1500 that lasts 1500 recharge cycles and the more expensive and higher capacity 2500mAh XX model, which is only certified to 500 recharge cycles. The Recharge Power Plus proved its worth in testing and is widely available at a fair price. When other brands claim capacities or charging cycles that look too good to be true, it’s best to stay skeptical. Unlike speciality brands, the Energizers are readily available in brick-and-mortar stores (like Target) or online at prices ranging from “acceptable” to “great deal.” In-store availability is important for batteries, because when you need batteries, you don’t always have the luxury of waiting a few days or weeks for shipping. The Imedion batteries performed almost identically to our pick but are a little pricier and harder to find. If the Energizers are out of stock or cost more than $3 each, get the Imedion AA 2,400mAh Rechargeable Batteries from Powerex. The eneloop batteries weren’t our favorite, but they’re a great deal when included with our favorite charger.
If you need to get a charger anyway, we recommend buying the Panasonic Advanced Individual Cell Battery Charger with four eneloop batteries. We clocked over a dozen hours of research and ran nearly 100 hours of controlled and real-world test cycles for this review on top of The Wirecutter’s hundreds of hours of research experience on batteries and past interviews with experts like the head of R&D at Duracell. During the research for this guide, we were also working on our new guide to USB battery packs, so we flew to Cadex Electronics to perform tests on those and learn more about battery testing in general. We’ve also been working with a new consulting electrical engineer, Lee Johnson, and we spoke with David Hobby of the Strobist about the demanding battery needs of professional photographers. Our top pick packs the equivalent of three or more times the capacity of a cheap disposable battery into a single charge.
Since Sanyo (now Panasonic) eneloop batteries effectively launched the modern rechargeable in 2005, their line has tripled capacity and doubled cycle life.
We’re running our own tests over the next few months, but Panasonic currently claims that their batteries will retain 80 percent of their charge after three years, and it’s reasonable to expect competitors’ batteries to perform comparably.
Your first set of eight AA batteries will pay for themselves in five to six recharge cycles compared to buying disposables. In addition to technology improvements, the price of rechargeables has come down considerably. Batteries don’t require hours assessing industrial design or critiquing the user interface. Look for new NiMH batteries that advertise “Low Self Discharge,” “LSD,” or even “Precharged!” that will hold a charge for years as opposed to mere months. After researching the chemistries, manufacturers, and common uses, we narrowed down our list of candidates to eight models from six brands.
The two specifications that matter the most are capacity, generally measured in milliampere hours (mAh),2 and cycle life, the fancy way of saying “our unrealistic measure of how many times you can recharge it before it’s dead.” Ideally, both mAh and cycle life would be as high as possible, but due to the way batteries are made, the reality is that improving capacity comes at the expense of cycle life and vice versa. Put simply, a battery has two main ingredients on the inside: cathode material—which determines capacity, and anode material—which determines cycle life. While there is a standard for life cycle testing set by the International Electrotechnical Commission, it’s completely voluntary, which allows companies to choose how to test that number and how to advertise it. We talked to David Klein, the director of R&D at Duracell, and he explained that different companies have different definitions of acceptable functionality.
We also think it’s safe to assume that these companies are all working with roughly similar raw materials, which means that EBL’s claim of 2,800 mAh and 1,500 cycles is likely overstated. In our experience testing USB battery packs, we saw sometimes minor and sometimes substantial variation between manufacturer claims and real-world performance, so we broke the battery testing into two different categories to get the most useful results. The Powerex MH-C9000 WizardOne is a bit tricky to use but offers superior testing capabilities compared to any other consumer-grade battery charger. When we picked our favorite battery charger, we didn’t recommend the Powerex MH-C9000 WizardOne because the extra button presses, settings, and information are all more than most people need day to day. Among other features that we didn’t use, the WizardOne has customizable charge and discharge settings, and it shows voltage, elapsed time, and cumulative power. With that accomplished, we grabbed one cell of each brand to be our chosen tester and set to work. Our pick, the Energizers, fell right in the middle, averaging 92 percent of their stated capacity on discharge—2,126 mAh. We were shocked to see the eneloops perform so poorly after reading so many positive reviews.
Standardized capacity tests don’t tell the whole story, especially because mAh ratings will change as you vary the rate at which you drain the battery.
But standardized capacity tests don’t tell the whole story, especially because mAh ratings will change as you vary the rate at which you drain the battery—just like you drain a tank of gas more rapidly when you drive at higher rates of speed.
To move away from the industry-standard mAh into real-world scenarios, we turned to the humble flashlight—but not too humble.
It turns out that Coast was a little conservative with their estimates, and you’ll have to watch flashlights for a lot longer than an hour and 15 minutes before the batteries die. Despite having 350mAh less available capacity than the Duracell, the Energizer lasted about 15 minutes longer in the flashlight test—virtually tied for first place with the Imedion, EBL, and eneloop Pro batteries. In our results graph, bars with similar heights are basically identical in a sample this small, since the difference between the first place Imedion to the fourth place eneloop Pro is less than five minutes. With Imedion, Energizer, and eneloop Pro leading the pack, we called on David Hobby to help us devise one last punishing test.
With a Canon Speedlite 270EX II sitting atop a Canon G12 and an intervalometer firing every 15 seconds, we maxed out the flash before we maxed out the batteries.
Since our charger picks all measure each battery independently, you can mix different brands when charging and not cause any problems. Overcharging batteries will eventually lower the cycle life, which means you’ll be replacing them sooner.
There’s quite a lot of speculation on some sites and in some reviews that certain cheaper brands might actually be Panasonic eneloops in disguise.
The AmazonBasics only powered our test flashlight for 2 hours, 12 minutes while the high-capacity version improved to 2 hours, 39 minutes. We doubt the AmazonBasics are identical, even if they’re proven to be made in the same factory. All the non-AmazonBasics batteries we tested did surprisingly well, and if we happened to see any of our top four on sale for $2.25 or less, we’d probably go ahead and grab them.


The Duracell Rechargeables were the only batteries to have a higher available capacity than the packaging claimed—2,473 compared to 2,400 mAh— but they were in sixth place on our flashlight test, lasting just 2:43. The EBL 8-pack High Capacity 2,800mAh Ni-MH Rechargeable Batteries are one of the least-expensive batteries we’ve found, and they had the highest available capacity in all our tests.
As a favorite in so many reviews, we were surprised that the Panasonic eneloop had the second-worst amount of available energy and ranked fifth in our flashlight testing. We actively moderate the comments section to make it relevant and helpful for our readers, and to stay up to date with our latest picks. The Wirecutter and The Sweethome are lists of the best gadgets and gear for people who quickly want to know what to get. This make them great for use in flashes, especially if you have multiple speedlights that don’t get used all the time. If you surf around most of the forums, you’ll see that a huge number of photographers, and speedlight users rave about the Eneloops.

They have a high energy capacity (2500 mAh), and they perform better than similar high-capacity AAs. Because they can hold their charge for so long, they are suitable for low-drain devices like remote controls and flashlights.
I do not recommend the Energizer or Duracell rechargeable batteries — these name brands seem to produce inferior rechargeables, perhaps to protect their sales of alkaline batteries. Eneloops can be recharged up to 2100 times, and they will retain their charged capacity even after years of storage. The Eneloop Pro has a capacity of 2500 mAh –this is 500 mAh more than the regular Eneloops. I then meter each battery after being fully charged INDIVIDUALLY and match the closest batteries as a pairs. A good quality charger will revive and recondition your batteries, and they will indicate if a battery is malfunctioning, which is quite useful. I just have a few questions, will this work on Xbox 360 wireless controllers or are these high powered, and for the charger do I need to purchase a separate one or will the kit(if there is one) be okay since I won’t be doing heavy use for it, just mostly for gaming and for some torch lights at home. In fact, after more than a dozen hours of research, a dozen hours of real-world tests, and over 70 hours of controlled testing with a pair of battery analyzers—including another 12 hours of real-world testing with flashlights and a camera flash—we found that the Energizer Recharge Power Plus are the best rechargeable AAs for most people most of the time. If the Energizers are unavailable, we recommend the Imedion AA 2,400mAh Rechargeable Batteries from Powerex, which performed similarly but are pricier and harder to find.
We'll be working on a new pick once we have the proper resources to devote to it, but for now we're archiving this guide. Instead of looking at just one of those metrics, our pick is based on a balance of realistic capacity and cycle life combined with a fair price. Their performance was similar; they had just 6 percent more available capacity than our top pick and were a statistical tie in our flashlight test. We spent some time looking over the various chargers and chose it as our favorite for most people because it’s accurate, safe, and completely automatic.
The engineers at Cadex lead the field in testing protocols and even make battery analyzers; their founder Isidor Buchmann is the face behind Battery University. We know that rechargeable batteries haven’t always performed consistently or well, but the latest technology—LSD NiMH1—can hold a much larger charge, retain it for much longer, and recharge more times than what was possible only a few years back. But a bigger breakthrough than capacity or cycle life is the incredibly long shelf life of the latest generation of NiMH batteries. That makes LSD batteries practical for emergency kits or other instances of infrequent use. Even after including the cost of a new charger, your first set of eight AA batteries will pay for themselves in five to six recharge cycles compared to buying disposables.
Properly charging batteries takes time if you want to preserve their long term performance—about eight hours for our top pick.
There are a handful of different battery technologies out there right now, but the only ones that will truly replace your alkaline AAs are nickel-metal hydride AAs, commonly abbreviated as NiMH.
Because an AA battery has to be a specific size, if a manufacturer decides to max out one side of the material equation, they do so at the expense of the other.
For example, company A and company B might both make a 2,000 mAh battery, but company A claims that it lasts 500 cycles while company B claims 1,000. If an eneloop were charged once a week, it would be 38 years until it reached 2,000 cycles, or over five years of charging it every day. While it’s true that having higher-quality materials can produce some increase in capacity or cycle life without sacrificing another, we’d expect single-digit percentage increases, not exponential. First, we ran controlled tests on a battery analyzer to come up with some hard data on available capacity compared to the advertised or nominal capacity.
But for our purposes, or for anyone who wants the maximum amount of customization in charging profiles, the WizardOne’s extensive feature list fits the bill neatly. Setting up for roughly 70 or so hours of testing, we first took four cells of each brand, discharged them completely, then charged them at a nice and slow 300 mA.
It’s worth mentioning that because of small sample sizes, and because batteries can behave differently under different discharge and charge conditions, we’re not willing to split hairs on our results. Because batteries face a tradeoff between capacity and cycle life, we like brands in the middle of the pack on this test as they should be the ones balancing the two factors more equally. Consider the relationship of mAh to practical uses like a tank of gas to mpg: You don’t look at a tank of gas to estimate how many miles you can drive before it runs out.
The folks at Coast trusted us enough to loan four of their new HX5 pocket lights for testing. In fact, most of the batteries we tested lasted about 3 hours before dying (but dimmed noticeably around the two-hour mark). Hobby is a professional photographer and a big proponent of rechargeable batteries on his website, Strobist.
We only found one other person, Syl Arena and his Battery Torture Tests, that found the same barrier—56 shots at 15 second intervals—before their flash overheated and recycled more slowly than the voltage of the batteries.
LSD NiMH batteries don’t need be kept in the refrigerator or freezer, you don’t need to drain them before recharging, and they don’t need trickle charging to hold power.
On the other hand, you’ll want to keep battery brands matched when you’re using them to ensure similar levels of charge. On the other hand, fast charging batteries will eventually reduce their capacities, causing you to charge them more often. There are all sorts of technical reasons to not go too slow or too fast.
While it’s plausible to assume that AA batteries’ slimmer AAA cousins from the same brands would perform similarly, there’s no guarantee, and we’re not comfortable making recommendations based on our testing. And because rechargeable NiMh AA’s have capacities and voltage curves very different from their disposable alkaline counterparts, many companies suggest and sell C and D adapters that let you use AA batteries in devices that normally require the larger sizes. Independent reviews and enthusiasts have been floating the idea that AmazonBasics Rechargeable Batteries and the High Capacity version, which are considerably cheaper than their eneloop counterparts, are actually made by Panasonic.
The equivalent eneloops bested them by burning for 2 hours, 45 minutes and 2 hours, 56 minutes. It’s surprisingly hard to find the current generation for sale outside of Walmart, and their retail price averages about 45 cents more per battery than our pick. But you can usually get the charger with batteries at a lower price than the standalone charger. But at around $3.80 per battery, an eneloop Pro is the most expensive of our group, offering only 10 percent more available capacity than our pick despite costing about 25 percent more. LSD NiMH stands for Low Self Discharge Nickel Metal Hydride, a mouthful that you should just check for on the box.

However, they are ideal for use in high-drain electronic devices like digital cameras, where they out-perform alkalines.
Their only potential downside is that they can be charged 500 times — not 2100 times like the regular Eneloops. You can mix and charge AA, AAA, C and D sized cells at the same time on individual charging circuits. For digital cameras (like my 10 year old Canon Powershot 540) they have lasted well over their rated 600 cycles.
The charger *does* has short-circuit protection, over charge protection and reverse polarity protection. Do I need to get a more up to date charger for the batteries you have currently recommended?


But we also found that almost all the brands we tested are good enough for most uses if you can find them at a discount. If you need a charger, we recommend the Panasonic Advanced Individual Cell Battery Charger with Four eneloop batteries, which is accurate, safe, and completely automatic. Despite their lack of superlative performance claims, the Energizer Recharge Power Plus batteries performed well at each step of testing. However, the Imedion batteries are generally a little more expensive, and you won’t find them at your local big box store. Even though the eneloop batteries didn’t test well enough to be our top pick, they’re certainly a good value when bundled with the charger for less than $20—and for some reason, the charger is almost always cheaper when sold with batteries than when sold alone. If you gave up on rechargeables because they didn’t seem reliable or high capacity enough, it’s time to take a fresh look. Any batteries marked “pre-charged,” “low self discharge,” or “LSD” will retain their charge for potentially years, not just months. Michael Bluejay’s Battery Guides have a wealth of information on the underlying technology and the history of its improvements, and he’s updated and added additional testing between when we reviewed his work in September and when we published this guide. And the benefits go beyond your wallet: Globally, over 10 billion alkaline cells are made every year, and roughly half are purchased in the US. If you always keep the extras charged and sitting next to (not in!) your charger, they’ll be there when you need them. We wanted to find the best, most quantifiable value–a reliable mix of capacity, life, price, and availability. For example, the regular eneloops claim a capacity of 2,000 mAh and a cycle life of 2,100 recharges, in contrast with the higher-capacity eneloop Pros that claim 2,550 mAh and only 500 recharges.
C-units provide a handy shortcut to describe the charging speed e, regardless of a battery’s capacity. But if A defines functional as 80% of original capacity and B defines it as 60%, the numbers don’t mean much. Just because the Imedion averaged 6 percent higher capacity than the Energizer doesn’t mean it’s obviously superior.
EBL, for example, had the highest overall discharge capacity, but because of that, we aren’t willing to believe the 1,500-charge cycle life claim. The eneloops claim 2,100 cycles to the Energizer’s 700, but again, we can’t be sure how manufacturers are come up with their numbers and there’s no quick test. Rather, you look at the kind of driving conditions—25 mph and maybe 75 mph on the highway; for batteries, you look at the kind of purposes. The Coast HX5 is rated for use with a single disposable alkaline AA, a rechargeable NiMH AA like we were testing, or even a high voltage Li-Ion battery. Despite having 350mAh less available capacity than the Duracell, the Energizer lasted about 15 minutes longer in this test—virtually tied for first place with the Imedion, EBL, and eneloop Pro batteries. It’s a good limitation for photographers to know, but after looking over the overall flash results, we didn’t think they were reliable enough to publish. If you use one of our recommended chargers, the only care they need is to be taken off when they’re done charging to avoid power leaking into and overcharging them. If you’re into learning about that sort of thing, jump over to the charger guide to learn the basics. We tested AAs first because they’re more popular and their larger capacity—typically around 3 times as much as their AAA counterparts—mean that differences in performance are more noticeable.
We haven’t tested how well our picks perform under such grueling circumstances, but we’ll keep it in mind for further testing.
Since the specs are similar, we performed extra tests, cycling white AmazonBasics against eneloops, and black AmazonBasics against eneloop Pros side-by-side through four cycles.
Even in our camera flash tests, the AmazonBasics batteries only strobed 80 percent as many times before being completely run down. The AmazonBasics, on the other hand, should be skipped—especially because at around $2.12 per battery, they’re not much cheaper than our picks and their better overall performance.
But because of the technological tradeoff between capacity and longevity, we’re not willing to put much stock in their cycle claims: 1,200 in some places and 1,500 in others. But if you need a charger, we do think that the Panasonic BQ-CC17SBA is the best one for the most people, and it’s often cheaper to get with four batteries anyway.
Higher capacity and lower cycle life is important in some situations; photographers might want to squeeze every flash they can between battery swaps. When you need it, though, you want that third one to work, whether it’s next week or six months down the line. The Cycle Energy batteries have performed flawlessly for me, and I’m starting to use them in all of my AA devices. However, on average most people will charge their batteries about 100-200 times over a 5 year period. After so-so life from the Harbor Freight specials (usually 4-500 of their advertised 800 cycles), I’m getting 3+ years and maybe 800+ cycles from each pair and have taken about 20,000 shots and 500 hours of video. The better chargers will recondition the batteries, and they allow you to weed out the problematic batteries easily. We measured an average capacity of 2,126 mAh in controlled bench tests and they finished in a four-way tie in our real-world flashlight tests with a burn time of about three hours. There are many “fast chargers” available, but we don’t recommend them, as they degrade rechargeable battery life.
Rotating batteries this way is like having a perpetually stocked supply without going to the store. Almost all consumer-grade batteries, such as those tested in this guide, should be charged at 1 C or less; a gentle charge that ensures longer life is ? C or lower. Because we know that cycle life comes at the expense of capacity, and since both those fictional batteries have the same capacity, we can infer that they probably have a similar real cycle life and any variation comes from the quality of the materials being used.
We like that some of the Energizer promotional materials more realistically claim “up to 5-year battery life when used under normal conditions.” That seems more reasonable, and, when charged once a month, would bring your cost per charge down to less than a nickel.
We’ll discharge them in a few months to gauge shelf life, and we’ll update this guide when we do.
We’ll continue investigating the most practical way to test cycle life, but until we can verify claims, we’re going to pass on batteries like this that fall way outside the norm. We’re assuming a more realistic five-year life with between 60 and 260 cycles until we see unbiased data that says otherwise. Using a state of the art flashlight-and-battery-testing rig that was definitely not an old moving box, we set a camera to record the exciting results.
The opposite was true of the AmazonBasics; it did well in bench testing, but was solidly last place in flashlight performance.
But because the batteries ranked in roughly the same order as the flashlight test, we feel confident that our picks from Energizer and Powerex will perform well in a photography setting. If you’re really into that sort of thing, you can wander off to more technical sites that will explain why Negative Delta V Detection and pulse charging are the way to go.
The two brands were statistically identical throughout—we had even started a draft calling them out as such. While we know this has something to do with a faster voltage drop, we didn’t have the equipment on hand to measure exactly what was happening. In general, though, this isn’t a good tradeoff for most people and isn’t worth the premium price. That was until Sanyo came out with the Eneloop batteries, the first low self-discharge NiMH cells.
Plus, NiMH batteries also give faster recycling times than alkalines when used in camera flashes. For example, if you charged your batteries twice a week consistently, it would take 5 years to reach 500 charges.
Panasonic recommends keeping the batteries in a cool location to maximize charge retention. After 5-6 cycles, I get a solid full charge in them and meter test again for matching up pairs.
The Energizers handily beat the popular eneloops in both tests, offering about 16 percent more capacity and 7 percent longer flashlight burn time, despite having the same average price per battery. Over four years, that would mean 12 rechargeable batteries take the place of 188 disposables—not a bad way to save some money.
The IEC tends to overstate performance by testing at ? C or lower, which yields capacities and cycles much higher than what most people will experience during day-to-day use. We had separately been testing the AmazonBasics head to head against the eneloops to address rumors that they’re the same battery inside. On average, Eneloops will hold 90% of their charge for up to one year and they can be recharged up to 1500 times with no significant memory loss that is usually experienced with other AA NiMH batteries.
The average of the discharged capacity is a fair measure of the usable power you’ll have in the battery. They looked incredibly similar at first, but this test shows that there’s a huge difference in real-world performance, and the AmazonBasics aren’t the great value we initially suspected.
