The reasons for a car not holding a charge: 1. Deep discharge: This means that when the vehicle is turned off, the car's equipment inside is still in a working state, continuously consuming the battery's power; 2. Aging generator belt: The engine directly drives the generator through the belt, and the generated electricity is rectified and stabilized before directly charging the car . If the belt is faulty, it can lead to a failure to charge, and it needs to be replaced promptly. The car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. The longer the battery remains idle in a discharged state, the more severe the damage. When the battery is not in use, it should be charged once a month to extend its lifespan.
