In Standard Batteries & Chargers

Right battery for my Glucometer.

Seems to last longer then your average AAA rechargeable batteries.

I’ve purchased several dozen of the Sanyo Eneloop AA and AAA batteries over the past few years. They will seemingly last forever if you use a good charger such as the POWEREX MH-C9000. Any charger used needs to have a microprocessor that can read the battery and keep from overcharging. Cheap chargers can permanently kill the batteries within a few charges. When new, before first use, I run a break-in charge that takes about 48 hours. When needing a recharge I run a regular charge but select a low 300ma charge rate which takes about 6-8 hours. If I do that, on subsequent charges, the batteries typically charge to about +5-10% of their rated capacity. After a number of charges, if they don’t exceed their ratings, I run a REFRESH/ANALYZE cycle that will bring them back over spec again. I haven’t charged any of these more than a few dozen times so I can’t say how long they will actually go. I use these batteries in everything in the house from remote controls to game console controllers to clocks and flashlights. I bought size adaptors to use AAs in size C and D applications. Remote batteries typically have lasted two years before needing recharging. The batteries have lasted in Wii controllers almost as long as alkaline batteries before needing to recharge. I keep about a dozen charged and ready to swap out as they hold up to 75% of their charge for 3 years sitting unused.
