Why is the car not charging?
2 Answers
The reasons why the car battery cannot be charged are as follows: 1. If it is caused by loose charging line connections, simply reconnect the charging lines properly. 2. If it is caused by a damaged charger, simply replace it with a new one. 3. If it is caused by low battery fluid, just add pure water and perform maintenance charging and discharging to restore the battery capacity. 4. If the car battery still cannot be charged, it may be damaged and needs to be replaced with a new one. Battery maintenance methods are as follows: 1. Regularly clean battery dust: Regularly clean dust and grease from the car battery terminals and apply special grease to protect the wiring harness. 2. Regularly check the lines: Regularly inspect battery accessories and connecting lines. 3. After the car is turned off, minimize the use of electrical devices. 4. When not in use for a long time, start the car periodically.
Last time my car wouldn't charge, it took me two full days to find the cause. At first I thought it was the battery aging, since it had been used for over four years, and the voltage measured below 12 volts. Upon closer inspection, I found the alternator output was insufficient, the belt was a bit loose and not properly tightened. Additionally, there was corrosion on the wiring connectors, and poor contact also affected charging efficiency. Luckily there was no accident - it would have been dangerous if the battery suddenly died on the highway. I immediately went to the repair shop to replace the battery and tighten the belt. Now I regularly check the battery status. If anyone encounters this situation, it's best not to push your luck - early repair saves both trouble and money.
