Why Can't the Battery Be Charged?
2 Answers
Here are the main reasons why the battery cannot be charged: 1. Deep discharge: When the vehicle is turned off, the car's equipment inside is still in working state, continuously consuming the battery's power. Prolonged discharge will accelerate the battery's degradation, requiring replacement with a new battery to resolve the issue. 2. Generator belt aging: The engine directly drives the generator through a belt, and the generated electricity undergoes rectification and voltage stabilization before directly charging the car battery. Therefore, any abnormalities in the belt can lead to charging failure, necessitating timely replacement.
The most common reasons I've found for batteries not charging properly are internal aging and malfunctions. When a battery has been used for several years, sulfate crystals form on the internal plates, which hinders the charging reaction. Another issue is internal short circuits, where damage to individual cells causes the entire battery to fail. From my experience, high summer temperatures tend to trigger these problems more frequently because the electrolyte evaporates faster, accelerating the crystallization process. If you encounter this situation, never force charge the battery to prevent explosions. I recommend stopping immediately to inspect it – if the battery voltage remains consistently low, it's safer to just replace it. Remember, regular vehicle use and avoiding complete discharge can delay this aging process, extending battery life by at least two to three years. Make it a habit to frequently check the voltmeter or use headlight brightness as an initial indicator – these small practices can save both money and hassle.
