Can You Overcharge A Car Battery At 10 Amps. I am of the belief that the minimum amps that you should use for charging a car battery is 4 amps and the maximum is 10. On the contrary a trickle charger supplies low voltage.
Mid-sized car batteries can be charged in 31 hours at 2 amps or 6 hours at 10 amps. 10 amps or more. The vast majority of car batteries on the market are lead-acid which can stand a certain amount of overcharging.
Answer 1 of 6.
Pressure build-up and the overproduction of gasses inside your battery can cause swelling. Basically the higher amps will allow you to charge a battery in a shorter period of time. Using a lower charging rate means that you are less likely to overcharge your car battery. 10 amps or more.
