Maybe in horsepower? A 100 amp hour battery has, sealed up inside, the capability to make 1.609 horsepower hours of energy .. The starter using 286 amperes at 12 volts is consuming 3432 watts which is the same as 4.6 horsepower. But it only does that for 1 second.. so the energy it used is 1/3600 X 4.6 = 0.00128 horsepower hours.
Power and energy aren't the same. Power can be horsepower but energy is horsepower-hours (or watt hours, or even ampere hours if everyone is talking 12 volts)
The "real" unit in English system would be BTU's or in metric units, Joules.. so the battery would have stored inside, the ability to supply 4095 BTU's... When the starter cranks the engine in 1 second, it has used only 3.31 BTU's .. Just casting around here for some understanding.. when ya have amperes acting over a definite time at a voltage, it doesn't need to be interpreted .. it is a calculable number .. as defined in physics.
Oh.. and don't put an ammeter in the alternator circuit!
