Customer Reviews

Best Rechargeable Batteries I've ever used... period!
As a professional photographer and environmentalist, I simply have to use rechargeable batteries, or I'd be throwing out AA's in large quantity.

In the past I've been unhappy with rechargeable batteries, they eventually held less of a charge and when stored, simply ran low and failed me when I needed them most.

These are simply the best AA's that I've used. I have lots of standby equipment.. strobes, back up cameras and associated equipment. I need things to work at full power for the longest possible time. The eneloops have a long shelf life once charged and this is very helpful.

Another plus, is that with photographic equipment, I was able to take far more photos on a single charge and my off camera strobe has a much faster cycle/recovery time than expected with rechargeables.

They are heavier than copper top AA's, I actually weighed them to compare... just an interesting fact. My aux battery holder uses 8, strobe uses 5 and the MBD-10 from Nikon uses 8, so battery weight plays. But the performance has become all I care about... that, and the fact that I'm not throwing away batteries after ever big event shoot.

I also appreciated that they arrived fully charged in their pack, so opening a new pack doesn't mean waiting to charge them prior to putting them into service.

I can't vouch for how they perform in other devices, but can certainly endorse them for photography.

Long shelf life, rechargeable, top performer...

Rechargeables That Has Shelf Life Close to Alkalines
The biggest drawback for Nickel Metal Hydride batteries is the shelf life. I got gadgets and toys all around the house, so I constantly charging batteries to have them ready when I need them. There will be very little juice left if you put them in the shelf unused for a couple of months. A waste of time and energy. Hence, one of the biggest advancement in battery technology is the arrival of the new low discharge Nickel Metal Hydride batteries. This is another great step in helping the environment. I have very few left of the old batteries since I started to replace all of them with low discharge batteries. Eneloops and Duracell are 2 of the best of its kind.

Pros:
-Low discharge.
-Well constructed
-Conventional size and dimension. I had other batteries that I have to use a screwdriver to remove from my camera because it is fatter than other "AA's".
-Looks so sleek and sexy designwise

Cons:
-More expensive than ordinary NiMh
-Not available at many stores
-Maxes at around 2000-2100 mAh

eneloop great product
i have many NiMh batteries that have a little greater amp hour rating than the eneloop .. but i find you can rarely use that extra capacity .. reason, the standard batteries self discharge quickly and in a week or so you cant depend on them .. you have to charge them just before you use them and thats inconvenient.. now comes the eneloop .. i love them .. you can charge them and not use them for months .. then you can depend on them to be at nearly full capacity when they are needed .. so you actually realize more usefull capacity than the others .. you dont have to charge them as often so the life time goes up .. they also can be recharged many more times than standard NiMh batteries again increasing useful life .. wouldnt it be great to have batteries like the eneloop in your cordless drill some day .. how many times has your drill been dead just when you need it (always in my case) .. with the eneloop you need only charge them once a year or so .. and its always ready when you are .. i cant wait until these batteries are available in such equipment.. the eneloop is working so well for me that i am replacing all my AA and AAA NiCd and NiMh and even some primary lithiums (photography) .. my flashlights are now eneloop and i dont worry about using them a lot or just storing them for an emergency .. its nice to have them always ready and dependable .. i guess you can say "i am a very happy customer" ..
