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.

Reduce waste and save money. Keep disposable batteries out of the landfills and save hundreds of dollars when you use rechargeable batteries versus alkaline.
AA rechargeables take up to 300 photos* per charge when fully charged. This is 8x more digital photos than Energizer Ultimate Lithium when recharged just 25 times.

NiMH rechargeable batteries do not have a “memory effect,” meaning that it is OK if you repeatedly recharge them after only being partially discharged. NiCad batteries have a “memory effect” and lose their maximum energy capacity if recharged before being fully discharged.
AA cells are 1350 mAh
