I left the key on --- for 3 months, so totally dead battery, no voltage at all, put my 3 amp trickle charger on the car, hand cranked it to start, took off charger, drove to show 40 minutes, battery up enough to start car then, drove home parked car-- never charged battery otherwise, got 6 more years out of battery

Another experiment-- I have a diode cutout, good pull with hand crank made 4 volts, enough to start car
