then you need a little more rpm to get the alternator to charge above the battery voltage. About 13.5 volts. The average alternator is now between 1,300 to 2,100 rpm. I set up an old 35 amp alternator to run off a 1/3 hp 1,750 rpm washing machine motor at a 1:1 belt ratio. Using the stock regulator would stall the 1/3hp motor. I put a large adjustable resister on the field connection of the alternator.
Alternator charges the battery at a regulated 5 A/h. It charges at a much lower rate than specified on the batteries usually 1/10 of their capacity. This is because charging at full pin would overheat the battery, generate high levels of hydrogen gas and dramatically reduce the longevity of the battery. 61 A/h battery at 5A/h charge rate would fully charge from dead in 12.2hours. The alternator is capable of generating 1.96 Kw. If it did all day both the alternator and regulator would probably self destruct. The battery only purpose is to start the car and run accessories when the engine is not running. Once started the alternator runs the whole show.
