Well, yes and no. That pesky law of physics known as the conservation of energy says you should get out of the battery whatever you put into the battery. There are a few issues to deal with, though.

1) Upon charging the batteries, some of the energy is given off as heat as the batteries reach their peak. Energy lost.

2) After peaking, some of the charge bleeds off very slowly, although it is very small. More energy lost.

3) When a battery discharges, more heat is generated, resulting in more energy loss. The discharge device will only measure what energy it is receiving from the battery less the heat loss. That's why a battery discharged at a lower amperage will look like its has more total energy (measured in joules) than one that is discharged at high amps.

Well, both Crimson Eagle and 071crazy have explained it well enough for me.

When buying new batteries, I go with the voltage AND the IR numbers to determine a REALLY, REALLY GOOD pack.

Thanks guys.
