Oh my! I can't remember all that stuff. I guess the lesson would be to
take them all out of the flash at once and charge them all together.
Until I get one of those intelligent chargers that chargers them
individually.
Yes - take them all out, charge them all, then put them
back in.
Regarding using mixed mAh rated cells:
Rich is right - if you want to do the best you can, then
you should use identical cells. But as a practical matter,
you can mix 2000 with 2200 mAh cells without instantly
inviting disaster. The proviso is that you don't discharge
them too far. That same proviso applies to using identical
cells - don't discharge them too far. You have more margin
for error when the cells are identical.
Concerning mixed rating cells: With 5 cells rated at 1.2 volts
each in series, and all cells fully charged, there will not be
the "cell reversal" phenomenom. That can't happen, until one
of the cells becomes discharged down to about .8 volts. With
identical cells, the discharge rate will be about the same
for all cells; with non-identical cells, some will discharge
faster than others.
Regarding charging:
With some chargers, charging 2 cells of different ratings
at the same time may result in improper charging. You can
build a simple and very cheap charger that avoids that,
and will happily charge cells of 2000 & 2200 mAh ratings
simultaneously. There are "smart chargers" that can do
better, but are more expensive.
One last thing - just because a charger is advertised as a
"smart charger" doesn't mean it is good for all rechargeables,
or for that matter, even the rechargeables it was "designed"
for.
