Do Car Batteries Recharge Themselves. Its an ingenious system that converts kinetic energy into electrical energy which is transferred and stored in the cars battery. The answer is YES yes the car battery does charge while the engine is idling.
A car uses quite a lot of electricity to work the ignition and other electrical equipment. Can your batteries recharge themselves. Using the alternator to recharge from a deeply depleted state is also very dangerous to your battery because it charges too fast.
Again assuming that the battery can still hold a charge.
Car batteries are usually treated as fit-and-forget items only getting any attention when they go flat or malfunction in some other way. If the power came from an ordinary battery it would soon run downSo a car has a rechargeable battery and a charging system to keep it topped up. The short answer to this question is no. If the battery is already charged however the energy is released or when it comes to some vehicles can actually do damage to the battery itself.
