Thanks for your reply.
Can you explain how the charging circuit works? ie, how the schottky diode
For one case, how does a charging circuit work? (You prefer NiCD's, so tell

I want to understand how current is put into batteries, initially, and how
and when to taper this when another criteria is reached (voltage?
