âI was quite shocked at the scope of the embezzlement,â he said. The Fall of California Democratic Campaign Treasurer Kinde Durkee Christine Pelisek March 28, 2012. But he was an enabler of the CEO's bad behavior, which I believe is a direct result of the firm's size and scope.
A 120 amp alternator in a typical modern vehicle can safely deliver 70% of that current continuously (84 amps). So say with the fan on medium, lights, ignition, small charging current to a full battery, etc there is a draw of about 45 amps. That leaves say 39 amps (550 Watts) of extra power available.
Idling a car for 5-10 minutes will not recharge a battery. It MIGHT replace a bit of the charge lost to starting it in the first place, but even that is iffy. The alternator in your car will need to hit, roughly, 2000 engine rpm to push a charge back to the battery.
