Hi mohiniss!

What kind of battery charger do you need, or, to be more precise, what kind of batteries are you planning to charge with it? NiCd? NiMH? LiIon? car battery (lead-acid)? Or something other? Next...does it has to be an "intelligent charger" or just a plain one?

There are loads of battery chargers circuits on the Internet.
Go to google and do a search on "battery +charger +schematic" and "battery +charger +circuit" (without the quotes, of course).

I'm sure you'll find what you need.

Thanx arcom,

kind of batteries are not specified in the problem definition, can you please tell me which will be better to charge...car battery (lead-Acid) can be a better choice..please give ur thoughts on this
It is just a mini project, we are planning to have 12v battery charger, which also indicates the user that .1. battery is charged fully 2. Battery charging is needed etc.
What will be the preferable battery charger as per ur say?

thanks.

I'll see what I can find. I know that I saw an "inteligent" battery charger using a PIC but I just can't find it right now...

BTW: Have you found anything you like?
