I use my Energizer AAA NiMH rechargeable batteries for everything. I use them in radio controlled cars, my MP3 player, flashlights, remotes, etc. They work great and last forever.
Modifying and driving radio controlled cars is my hobby, so I need a lot of AAAs. I got a couple packs of these a few years ago, and since then I have gotten 5 or 6 more sets. They last quite a long time in my cars. Iâ€™ve tried a few other brands of batteries (mostly non-name brand ones from the internet) that just donâ€™t cut it.
The shelf life is pretty good too. They can sit there and not be used for a while and still hold their charge well. After a couple of months of no use, itâ€™s usually a good idea to recharge them if youâ€™re going to use them. But for shorter periods of time they hold their charge quite well. Of all of the AAA NiMH batteries Iâ€™ve bought, these have the best shelf life.
These are perfect for any thing that needs AAA batteries: anything from digital cameras to remotes to electric screwdrivers. I highly recommend these for any need.
