Default the lie of rapid NiMH self-discharge

"Pre-charged" NiMH cells have a lower self-discharge rate,but they don't
seem to be all that more expennsive than regular NiMH.
they are slightly lower in mAH capacity.(2100mAH vs 2300mAH)


I'd ask the OP how many flashes or shots he got from his stored
NiMH cells before they needed recharge.
seems to me that 1.2V is pretty much "discharged" for NiMH cells.
ISTR that 1.1V is the low limit.


I didn't run down the flash. I will do so tonight or tomorrow.

1.25V is considered the nominal operating voltage of nicad or NiMH cells.
(The point another poster made about the relatively flat discharge was
well-taken.) The "discharged" point is, as it is for cells of most
chemistries, 1.0V.


What was the load current for your voltage measurement?
