* Overcharging: If your car's alternator is overcharging the battery, it can cause the battery to overheat and emit a frying noise. This can happen if the voltage regulator in the alternator is faulty or if there is a problem with the wiring between the alternator and the battery.
* Low electrolyte levels: If the electrolyte levels in the battery are too low, it can also cause the battery to overheat and make a frying noise. This can happen if you have been driving in hot weather or if the battery is old and has not been properly maintained.
* Loose or corroded battery cables: If the battery cables are loose or corroded, it can also cause the battery to overheat and make a frying noise. This can happen if the cables have been damaged in an accident or if they are not properly connected.
If you are experiencing a frying noise from your car battery, it is important to take it to a qualified mechanic as soon as possible. Ignoring this problem can lead to serious damage to the battery and other parts of your car.
