Battery Reserve Capacity to Amp hours

The Reserve Capacity is the amount of time that a battery can run at 25 Amps until its voltage drops to 10.5 volts. Reserve Capacity is measured in minutes.

Reserve Capacity = 2.4 x Amp hours (The 2.4 comes from 60 minutes in an hour divided by 25 Amps, 60/25 = 2.4)
