I have not had them long but so far they have been great. I tested them and compared them to my existing Energizer batteries. To be fair the Energizer are many years old but it is still good to know these new eneloop batteries out perform the old Energizer. I did extensive research prior to purchasing the eneloop batteries and from what i could find these are as good or better for household use than any of the competition. Eneloop does also make a higher strength (black) line but they don't recharge as many times as these (white) line and would probably be better suited for something with an electric motor as opposed to a TV remote or flashlight etc...

Seem like excellent batteries at a reasonable price, especially if you need a lot at one time. We have a multi-unit Panasonic phone system with seven 2-battery handsets and several were not holding a charge very long. They were the original rechargeable batteries in an older system about eight years old. A month ago we replaced them all with the eneloop batteries and they all now work like new!! It made a dramatic difference. Obviously too soon to judge how long they might last, but given that they are Panasonic we have great expectations :)

Great quanity batteries, they worked well. Long lasting.

We've been using Eneloop batteries for over a decade. (It used to be Sanyo, now Panasonic bought Sanyo). These batteries are all made in Japan and they've improved over the years. They're guaranteed to recharge hundreds of times and hold charge for over a year. We use them on everything from remote controls, mice/keyboards, toys, clocks and security devices.

I've been using Panasonic Eneloop rechargeable batteries and have been very impressed. They are the only AA and AAA rechargeables I use.
