The battery always loses power for the following reasons:
1. The driving distance is too short. Frequent ignition will damage the battery life.
2. There is a problem with the electronic circuit, causing the car lights to stay on. More than half of the batteries running out of power appear on the wires.
3. The engine is not charging, resulting in the battery not being replenished. There is a way to do this: use a multimeter to check the voltage before and after starting. If the voltage of the car does not change, drop or rise after starting, it means that there is a problem with the engine, which is most likely causing the battery to lose power.
4. If the battery itself is faulty, it needs to be inspected in the store and replaced in time.
Extended information:
Long-term loss of power in the car battery will cause engine abnormalities and actual fuel injection. Failures such as reduced oil volume, insufficient ignition power, audio inability to work or sudden suspension of work, etc. The battery should be maintained in time and the battery magic eye should be checked to ensure sufficient power.
