near
any belts or fans). Better yet use a jump starting box.
Does revving the engine charge the battery?
The battery will charge faster if you rev the engine faster
. Why? Because the faster the crankshaft turns, the faster it turns the belt that runs the alternator. And the faster the alternator turns, the more electricity it produces to run all the electrical stuff in the car — and recharge the battery.
