I wanted to ask a similare question. I have a bunch of 7.2 volt 600 MAH bat
packs. I want to make a charger for them.

In this fellows case wouldn't it be better to use a Zener regulator so that
it wouldn't overcharge?

Does anyone know of a schematic for these 7.2 AA packs? I'm thinking that I
could use something like this:


Batt (+) ___
o-------o----|___|-----(+)
| Charge
| x-former
'-----z<---o---(-)
Batt (-) |
o------------------'
