Re: [RE-wrenches] Capacity loss due to rapid dischargeThat is not quite true.
Some of the loss is in heat due to internal resistance, and that cannot be
recovered. High discharge rates also significantly affect overall battery life,
which is not part of the equation but must be considered.

Subject: Re: [RE-wrenches] Capacity loss due to rapid discharge
Thanks, Kent,
It is clear then that high discharge rates have a big effect on the voltage,
but only a small effect on the actual battery capacity. That was my instinct
but it's good to have it confirmed. And this will be important information for
those who use Peukert's Law 'naively' to conclude that a battery has
dramatically lower capacity when discharged at higher rates. (In fact if it
were true that capacity is reduced to this extent it would also have very
serious implications for battery efficiency.)
