This one got me to thinking.

True about the mucho amps during recharge but this holds true with a low battery situation or not regardless of jump start or not. The alt or gen will, under regulation, restore the charge to the battery using as full a load as is posable given the RPM. An example would be a push start or even a so low it just barely cranked over start. There will be max load from a low charge start on a cold rainy night. Recharging while running the lights, blower and wipers. Add the AC clutch for late cars that use AC to help with defrost. while the alt is fully loaded the car is moving the air over is cool and the temp rise on the core will remain in check. A hot summer night and the car sitting while the bat recharges might run the core temp well over what would be seen otherwise.

Recharge cycle duration is the difference. That is to say how long the alt or gen is running at full cap to restore the charge.

There was a situation at a track this year where a late model 911 had a battery momentarily installed reverse polarity. This "Let The Smoke Out" of many electrical components on the car and knocked it dead. This same thing on a 912 with stock electrics might have done little if corrected quickly.
