Eneloop's next-generation nickel metal hydride battery 4pk AA NiMh 2000 mah batteries.

Batteries have a property to release the stored energy in small amounts (this phenomenon is called self-discharge). This property is particularly noticeable in rechargeable batteries such as Nickel Metal Hydride Batteries etc. as compared to dry cell batteries, hence disabling rechargeable batteries from becoming batteries that customers can use immediately after purchase. For this reason, rechargeable batteries couldn't be used unless charged after purchase and so lagged behind dry cells in convenience. This new products main property is that it has introduced great improvements in self-discharge properties (residual ratio after one year of non use is 85%*, in temperature conditions of 20 degree Celsius according to research). Through this breakthrough development, Eneloop has realized a rechargeable battery that can challenge dry cell batteries in user-friendliness through features such as making possible use immediately after purchase or once charged, its ability to be used anytime.

Features and Specifications:
  • Immediately usable new rechargeable battery
  • Eneloop batteries can replace alkaline batteries for all your needs and can be used in any application where AA batteries are needed.
  • Extremely Low Self Discharge
  • High performance even at low temperatures down to 10 °C during your winter vacation
  • No Memory Effect - Recharge at any time.
  • An Environmentally-friendly product right from the battery to the packaging
  • Comparatively more powerful and longer-lasting than dry cell batteries and superior low-temperature electrical discharge performance
  • New and Improved! Can now be charged up to a 2100 times.
  • Economically more efficient than dry cell batteries, Eneloop can be used 1000*1 times over. Also, no need to worry about memory effect.
  • Eneloop is a state of the art Ni-MH battery which can be charged like any other Ni-MH battery.
  • Can be charged by using any good quality NiMH Battery

I've been using Eneloops for over eight years now and have never had an issue with them yet. No leaks and none of my oldest ones have failed to hold a charge yet. I've had other brands that failed me after only two years.

I'm a photographer. I use 36 of these when doing location shoots. I already had 68 of these. I needed four more. These can't be beat.

The Best
November 25, 2014
These are simply the best AA rechargeables out there. I have a high end Sony digital camera, which simply chews through batteries. Before I started using eneloops, I was using another brand, and the camera would kill those batteries with no more than 50 photos. With the eneloops, I get 200 - 300 shots easily. Also, you can leave them in the camera for months, and they still have current. Do yourself a favor and buy a "smart" battery charger to go along with the eneloops.

My favorite NiMh battery
November 25, 2014
They rock. The first battery that actually let you use NiMh chemistry just like you would use normal batteries rather than having to charge them just before use. Use them a lot in my photo gear.
low self discharge, decent mAh, decent lifespan
They don't train your wife and kids to not throw them out and put them in the "needs recharging" box.

Best Rechargable NiMH's

The originals
July 4, 2014
Solid batteries, one of those technologies that just works. Can't go wrong with eneloops! They work on such a broad range of applications because of their low self discharge. Pretty much anything. I use them in my razor and tv remote, and EDC flashlights.
- Low self discharge - Battery junction price - Good capacity - Lots of recharge cycle
- Price. You can get most of the same specs and reliability in other brands (maha) for cheaper - other models have better capacity (maha immedion, eneloop pro)

Great rechargeable AA for flashlight
July 1, 2014
I use them in my Fenix E12. They look good and are solid. It takes around 6-7 hours to charge when empty in a Panasonic charger. I like the fact that you can charge any eneloop any time without worrying about the memory effect. All my flashlights are now using eneloop.

Excellent for emergency use
May 8, 2013
I got numerous Fenix products from Battery Junction in preparation for possible energy crisis or storm blackouts, and after having alkalines leaking outside the package well within their expiration date, I realized that NiMH was the way to go. Regular NiMH will not reliably hold a charge long enough to be worth using in emergency lights. With the Eneloops, I simply recharge them and place them in the device. About once a year, I intend to give them a top-off charge because they do lose 10-15% of their charge. In my Fenix bicycle light (which is very demanding but extremely high quality), I charge them daily and the batteries work perfectly. In a quality charger bought at Battery Junction, they take about 2 hours to top-charge. In devices ranging from my bike light (used nightly) to my Fenix HP20 headlamp (perfect for the one time we get a blackout at work with a dead generator), these batteries work perfectly. And I do recommend getting them here, instead of elsewhere. I have looked at a major site that sells them, and read the 1-star reviews there. About half were charger or accessory issues; most of the rest were because they either sold fake Eneloop batteries or had packaging errors or sold outdated product. At Battery Junction, you get the genuine product and quality merchandise. I recommend using the real thing--and it is worth every cent I paid for them to get top quality. And Sanyo Eneloop batteries beat the mass market batteries in reliability.

Workhorse Battery
April 26, 2013
I use alot of AA nimh rechargables in everything especially my flashlights and radio scanners and have found these outlast and outperform the bigname brands found in the local stores. These last double the time of the others in my radios which is important when on storm duty or power is out. I used them during Sandy when i had no power for a week. In 2011 keeping all my radios and lights on all week without running out of charged batteries. Get a good Batteryjunction charger for them and you\'ll save money every time you charge them

Eneloops - the only AA batteries that I trust.
June 22, 2010
I have been using Sanyo Eneloop AA batteries for about seven months now and they are, hands down, the best AA batteries that I have ever used. They last a long time both in use and when in storage. My flashlight, a Fenix TK40, is notorious for showing the limitations of various types of AA batteries. If high quality batteries aren\'t used, even brand new ones fresh from the package, the highest \"turbo\" light output setting on the TK40 will noticeably not be much brighter than its next highest setting. With ordinary alkaline cells, the turbo mode becomes the same as the high mode, but with Eneloop batteries, the turbo mode definitely blows away all the other settings. That is still true today, about seven months after I first bought my first set of Eneloop batteries. One of the best things about the Sanyo Eneloop batteries that isn\'t mentioned on the product packaging is that they do not leak. Alkaline batteries are notorious for leaking, even when brand new, so I do not suggest using them in any electronics that you care about. Sanyo Eneloop batteries just do not leak at all. Thus, I use them in all of my electronics that require AA batteries, including not only my high quality flashlights, but all my Nikon camera equipment (F-100 and SB-23) as well. After discovering Eneloops, I will never ever use an alkaline AA battery again. Do yourself a favor and replace all the alkaline AA batteries in your house with Sanyo Eneloop AAs. All it takes is one alkaline battery leakage to ruin your electronics gear and thus the cost of the Eneloops is money well spent. Yes, they are *that* good.

Fantastic batteries
August 13, 2009
Took 110 pictures right out of the package and still going strong.If you are tried of buying rechargeable batteries and having them go dead a short time after taking them off charger this is the battery for you. I just wish i could rate them higher than five stars.
