It is basically charged the same way and has all of the faults of he NiCd
(voltage depression, etc.) but while it has a higher average capacity, it does
not have as much current delivery (higher internal resistance.) The cells peak
charge in a similar manner, but the delta drop-off when charged is less
obvious. I don't know much about these cells beyond that. I suppose I will
need to read up on them soon...
I recommend, again, a good peak charger for best battery health. Two chargers
I know will deal with them, the Novak Millenium and (I think) the Tekin BC112.
Neither of these are cheap though (>$100). Others may have lower cost ones,
but I don't know them.
have fun,

| Thanks for the tip. I think you are right. I got a NiMH catalogue from Panasonic and it makes some of the same recommendation such as charge rate, etc. It is much like NiCD if you charge the battery "watching the clock".
