Summary: re-charge
Comment: So far these have been great batteries. We use them in our remotes & 1 or 2 or our sons toys. They've held their charge for several weeks now in the toys & since the remotes don't use much power, I expect longer use for those.
NOTE: You need to use the overnight charger, the NiMH version, not the quick charger. If you use the quick chargers they won't fully recharge. The chargers MUST be for the type of rechargeable battery you have.
A great way to save money in the long run. Great batteries for a good price, fast shipment as well. I'm getting another pack soon as we seem to need a few more...

Summary: Exactly what you expect - rechargeable batteries
Comment: Energizer rechargeable batteries last for decent periods of time in kids "Shake 'em up" cars, "Geo Trax" trains and buildings, computer mice and cordless keyboards. My only knock against them is that they seem to lose their charge while sitting around to be used again. Instead of fully charging them then setting them aside until ready to use, I wait until I need them and charge them over night - an inconvenience when there is a sad child involved! This is true for both the "AA" and "AAA" sizes.

Summary: Two years and still no complaints
Comment: I bought these about two years ago along with the Energizer charger and AA pack Energizer e2 Charger for AA & AAA Rechargeable Batteries with Car and Home Adapter & 4 AA Batteries (though I bought mine from Best Buy) and have yet to experience problems with any of them. After 1000's of hours of use (combined, so I'll guess somewhere around 500+ hours of use per battery) I haven't noticed any degradation in performance. (I've mostly used them in mp3 players, but also a bit with headlamps/flashlights.)
Bottom line: these batteries have done precisely what I expect them to do - keep the music going.

Summary: Rechargeable and always ready
Comment: It is very convenient to have spare rechargeable battereies on hand. This way you always have fresh batteries for your electronics. I am currently in Iraq and I use these batteries for my headlamp and Bose noise cancelling headphones. These batteries seem to hold a charge longer that traditional batteries and it is very convenient to know that you always have a fresh set of batteries available. It is the worst thing for your batteries to die and not have a spare. I switched to rechargables about a year ago and will never go back.

Summary: Energizer batteries
Comment: I find these batteries are ok for use in a product...I don't expect them to be as good as a regular battery. However, you need to charge them right before your trip...unused charged batteries do not seem to hold their charge. In the past I've used Rayovac batteries and chargers for a period fo 10 months for the batteries. I don't use these batteries that frequently so I don't know how long they will be rechargable.
