The cold cranking amperes (CCA) of a conventional lead-acid automobile battery is the amount of current the battery can provide at 0°F for 30 seconds and maintain at least 1.2 volts per cell (or 7.2 volts for a standard 12-volt battery). If a battery is rated for 700 CCA, how much work will it deliver to the starter motor, assuming the minimum voltage (7.2 V) and maximum time (30 s) are required?
