Why Can't the Battery Be Charged?

[KarterRose]

There are two scenarios where the battery cannot be charged: 1. Severe battery degradation: The car battery not charging is most likely due to deep discharge, meaning that when the vehicle is turned off, the car's equipment inside remains in a working state, continuously consuming the battery's power. Prolonged use under such conditions will accelerate the battery's degradation, requiring a replacement of a new battery to resolve the issue. 2. Aging generator belt: The engine directly drives the generator via a belt, and the generated electricity undergoes rectification and voltage stabilization before being directly used to charge the car battery. If the belt malfunctions, it naturally results in the inability to charge the battery, necessitating timely replacement. However, this factor rarely occurs because during major vehicle maintenance, the generator belt is inspected, and if it has aged to a certain extent, it will be replaced with a new one.
