From 100% discharge, a small car battery (200-315 CCA) can be charged in 24 hours at 2 amps, or 5 hours at 10 amps. Mid-sized car batteries (315-550 CCA) can be charged in 31 hours at 2 amps, or 6 hours at 10 amps. Larger vehicle batteries (550-1,000 CCA) can be charged in 50 hours at 2 amps, or 10 hours at 10 amps.
