Charging Current calculation of battery

Other Hardware General Electronics

hello Experts,

I want to know how to determine the charging current and voltage for rechargeable AA batteries. I want to know about NiCd, NiMh, Lead-Acid batteries(6V, 12V) charging currents. Now I'm having a 1.2V, 850mAh NiCd battery, I was designing a circuit for that I need this charging current.

Thanks.

There's no substitute for the manufacturer's datasheet for the exact batteries in
question, alas.
