Most Ni-Cd chargers will happily charge a Ni-MH though normally take longer
due to the Ni-MH higher capacity and as noted above may not quite achieve
full cell capacity.
One thing to note however is that the AA Ni-MH cells I have seen are not
stamped with a extra-fast recharge rate; my 1300mAH Ni-MH cells are rated
as 210mA for 8 hours or 130mA for 14-16 hours, whereas my 650mAH Ni-Cd are
350mA for 2 hours or 150mA for 5 hours, or 65mA for 14-16 hours. Both
cells are manufactured by Uniross by the way.
Whether the Ni-MH could be safely charged at, lets say 350mA for 4 hours I
know not, though I'm tempted to think doing so may shorten their overall
number of useful recharge cycles, and given modern Ni-Cd generally are
stated as having about twice the cycles of Ni-MH I don't think its worth
risking it. So whilst I have few qualms about charging the Ni-Cd in my
R3, I won't do that with the Ni-MH.
