Re:sanyo eneloop AAA batteries - 2007/08/27 20:20
Hello Vhbaske,
The low self discharge cells are rated at around 70 F. At higher temperatures, their self discharge rate increases. However, it still should be less than normal NiMh cells. I am not aware of any elevated temperature testing, so I don't know what to expect from them at higher temperatures.
Your tester is trying to extrapolate remaining capacity from a voltage reading under load. This is great for matching cells for use in a multi cell application, but this type of testing usually falls down on accuracy of the remaining capacity.
Since you have a C-9000, take your Eneloop cells that are testing at 80% and discharge them using a 500 mA discharge rate. The Eneloop cells have a rated capacity of 2000 mAh, and have usually been coming in at around 1930 mAh when discharged at 500 mA. 80% of 1930 = 1544. If your cells show a discharge capacity of around 1544, then your tester is correct.
It will be interesting to see what you come up with.
