Low Self Discharge rechargeable AA battery test results

Just last week, Digital Photography Review forum member arcae86 completed a battery capacity test that took several months. The test measured the retained capacity of 8 different brands of AA low self discharge (LSD) AA batteries. The brands tested were Sanyo Eneloop, Duracell precharged, Hybrio, Powerex IMEDION.  Battery capacity measurements were taken 1 hour after charging, and again after 1 week, 1 month, and 3 months. At all measurements periods saw the Powerex IMEDION AA battereis to have the highest capacity of all 8 brands tested.

For simplicity’s sake, I have taken the figures from the 4 commonly available brands available in Australia  (Sanyo Eneloop, Duracell precharged, Hybrio, Powerex IMEDION) and graphed the results below:

1. I wish you hade sat them for six months and one year. I wiuld like to see how they hold power long term.

   Thanks for all the information I will not be buying any more of the 2650/2700 ones. I stopped using my Duracell battery fryer, unless I really need batteries fast..
