Q
does revving engine charge battery when jumping
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
Yes, revving the engine can help charge the battery when jumping, but with nuances worth understanding. Normally, a car's alternator, which charges the battery, works more efficiently at higher RPMs than at idle. This means, if you're trying to jump-start a car and it's running, slightly revving the engine of the donor car (not excessively) can indeed help by increasing the alternator's output, thus sending more power through the jumper cables to the dead battery. However, it's important to rev gently to avoid any potential electrical issues or damage to the vehicles. This method should be part of a broader understanding of safe jump-starting procedures, ensuring connections are correct and both vehicles' electronics are protected. Always refer to the vehicle's manual for specific advice.
