  • Battery Discharge rate

    With a 420ah@12 volt battery what is the max Discharge rate for 5 mins? And would it be the same for 30 minutes?

    It really depends on the chemistry of the battery. Higher rates are acceptable for Li or AGM type batteries but not FLA.

    Usually the manufacture specifications will provide specific discharge and charge rates for a particular model.

      golf cart FLA. Specs gives 107 minutes at 75 amps. 151 minutes at 56 amps. Does this mean I can Discharge at 75 amps?

        My guess is that a golf cart battery can provide a "high" discharge rate for a short time, it will not provide the same "high" rate for 30 minutes.
