Google for 'starter motor current'. If a car wont start, I either
put it on charge or just go an buy a new battery using a different
vehicle.
A normal starter motor draws upwards of 300A when cranking the engine
but there's no starter motor in a hybrid and all the 12V battery does
is power the entry/exit system and boots the computers to get the
hybrid system to the READY state, a draw of less than 20A.
How does the IC engine start without a starter motor? it may well be a
combined generator and starter, though.
Like bump starting?
