Customer Review: The best rechargeable batteries
Summary: 5 Stars
I love Nickel Metal Hydride batteries. I got gadgets and toys all around the house, so I constantly charging batteries to have them ready when I need them. But as you know, they are unuseable after you put them in the shelf for a month. Which is a waste of time and energy. If you really want to be green, then you need these low-discharge batteries. I have started to replace all of them with Eneloops.
Pros:
-Low discharge.
-Well constructed
-Conventional size and dimension.
-Looks sexy and sleek
Cons:
-More expensive than ordinary NiMh
-Not available at many stores
Now there are bunch of low-discharge batteries coming out. Kodak, Rayovac, I also see some at Thomas Distributing, some are cheaper than Eneloops. I do not want to mix them up, plus have not tried the others. So, I stick with this brand at this time.
It is kinda strange though that the Eneloop kit (I purchased from Costco for 26$ - 1 battery charger, 8 AA's, 4 AAA's plus a pair each of D & C size adapters) is not available in Amazon Prime but the others are.
I find those adapters (spacers) very useful.

Customer Review: Vastly better than the Sony rechargeables they replaced!
Summary: 5 Stars
I've been using rechargeable batteries for most of my battery needs (primarily remote controls) for five years now. Previously I was using the Sony units, which worked all right, but seemed to go from "fully charged" to "too weak to actually register a button-press" in just a few weeks. I'd really rather recharge my remote control batteries every...oh...month or two if possible, but that just wouldn't work with the older technology.
Eneloops are different. While they may not have as much peak capacity (so might not be great for digital cameras, for example), they HOLD THEIR CHARGE for a long time, and are MUCH better for remote controls and other items that use little power over a long time. I have actually been testing the Eneloops against my previous Sony batteries (still using the old Sony charger, which is a nice unit) and can always tell when a remote isn't using Eneloops -- it craps out much faster, and when it craps out, it's dramatic versus the slow fade of the Eneloop.
So anyway -- if you're using these for remote controls, DEFINITELY get them. They are very much worth it.
Customer Review: Not your normal, crummy NiMH battery
Summary: 5 Stars
I replaced the batteries in my engineering model calculator with three AAA eneloops several weeks ago. The batteries have kept going and going compared with regular NiMH AAA's which are not suitable for long term low drain devices like this because they won't keep going and going. They disapate far too quickly. You would have to recharge them so often it would make you crazy.
I also like the idea I can keep several sets of eneloops charged up and ready for use in my camera, a high drain device, for which a regular NiMH might be useful. Problem is I don't take all my photos within a day or two and regular NiMH's disipate. Once again, I have to recharge. Not so with eneloops. For me these batteries are the greatest.
2700 mAH's (or more in the future) of energy storage capacity for the highest regular NiMH's does not trump eneloops 2100 mAH for me if most of the 2700 mAH's disipates within days of its having been charged. TV remote controls, calculators, shavers and all sorts of uses where alkalines were more appropriate eneloops (or other hybrid NiMH batteries) can now be used. Good job!
Customer Review: Why would anyone use anything else?
Summary: 5 Stars
I just happened upon these a little over a year ago while looking for a battery charger for AA and AAA batteries. With 2 young children, we had plenty of uses for batteries. I found an excellent charger (the LaCrosse BC-900) based primarily on the outstanding review of NLee the Engineer who also recommended hybrid-type or low self-discharge batteries. I had honestly never heard of such a thing before that (since hardly anybody sells them apparently). These are especially great for use in electronic items that get used a lot but that also may sit unused for long periods of time (i.e. digital camera, Wii remotes, etc). The beauty of these batteries is that you can throw a few in the camera bag and always know you've got good batteries even months later (unlike with regular rechargeables which lose their charge much more quickly over time). I rarely use any other type of battery now. These are expensive on the front end but have proven to be the most cost-effective and convenient batteries to own. For an excellent (and much more technical) review of these batteries, read the review by NLee the Enginner.Customer Review: Best rechargeables currently available
Summary: 5 Stars
These batteries have one major advantage over most other rechargeables - they retain their charge much longer. This is especially useful for my digital camera. I don't use it every day and may go 2-3 weeks between uses. With other brands I would always have to charge up a new set of batteries each time I used my camera because they would discharge while sitting idle in my camera for 2 weeks. Now I can just pick up my camera and go.
These don't have the highest capacity out there, but since the higher capacity batteries discharge pretty quickly, I find that I actually get a lot more usage from these than I did from 2500mAh Energizers. I hope they do come out with a higher capacity version eventually, but even now they beat all the competition out there.
Edit: I should add that I mistakenly put this review under the AAA batteries, when I meant to put it under AA batteries, which is what I was thinking when I compare them to Energizers. But I do also use the AAA Eneloops and everything that I said about the AA size goes for the AAA size too
