Rayovac Pre-charged Rechargeable NiMH AA Batteries

I have been using these batteries for a while .I can defiantly say that these have saved me lots of money over disposable batteries  especially since these can be bought In a 8 pack for $13.97 at Walmart and come precharged. I try to always keep one fresh pack unopened and ready to go in case I forget to charge a set.

Recently I decided I would try a few other brands to see if there where any better deals out there but first I wanted to see what kind of capacity these batteries had to get a base line I used my GT Power X-Charger C6 to discharge the batties at 1 amp  down to 1 volt each and then recharged them at .5 amp and then a second discharge . The capacity that the charger reported with each group of batteries ranged from 650mah to 1450mah depending on there age . The oldest  group of 8 are about  2 years old and probably have over a hundred cycles through them with the newest having 2 cycles through them .

So far I have not had any complete failures but more than likely age will start to catch up with my oldest cells in the future.
