On a car battery? on most battery chargers there are three settings trickle or something around 2 amps which will take a good 12 hours to 24 hours a second for small batteries which is a few more amps that could take anywhere from 6 to 12 hours and a fast charge which is even more amps and anywhere from 1 hour to 4 hours, also some chargers have a start option which cranks over a car so the alternator will charge it correctly, the trickle charge is the best charge but will take the longest
