I'd like to make a simple battery charger for AA batteries. My
requirements would be:
-Uses an AC->DC plug-in-the-wall adapter (I have a few of these laying
around)
-Will always charge 4 AA batteries at once (so I guess that's 6V in
series, or should I charge them in parallel?)
-I hope that the batteries will have the same initial charge when they
are "dead". They will be used in my Canon A60 camera which takes 4 AAs
-I'd like them to not get hot after they have finished charging. So I
could either charge them non-linearly or have the circuit cut-off once
they are "full".
If there are any circuits available on the Internet, please let me know.
Google didn't turn up anything for me so far.
Thanks,
Dave
