Common fault problems and treatment methods of car battery

There will be no symptoms when the car battery is used in the early stage. Once there is a problem, the battery basically needs to be replaced, so the maintenance of the battery should start from a new car or after installation.

1. The first charge of a new battery or a repaired battery before use is called the initial charge. Whether the initial charge is appropriate or not is extremely important to the future performance of the battery. The characteristics of initial charging are small charging current, long charging time, and sufficient electrochemical reaction. The initial charging of a new battery should be carried out one to three cycles of charging and discharging.

2. The starting time should not exceed 5s each time, the starting interval should be greater than 15s, and the starting time should be 3 consecutive times at most.

3. If you encounter traffic jams or waiting for people, in order to save fuel, most car owners are accustomed to turning off the engine and listening to audio or watching DVDs in the car, but this will consume a lot of battery power. It is recommended that the car owner should not listen to the radio for more than 30 minutes when the flame is turned off, and high-power devices such as DVDs and external power supplies are not recommended to use, because this will easily consume the power stored in the battery and damage the battery itself. Not small, it will also affect the normal starting of the vehicle.

4. If your car will not be used for a long time, it is best to unplug the negative electrode of the battery. Because there is also a weak current consumption in the vehicle circuit system when parking, leaving the vehicle for a long time will cause the battery to run out.

5. Wipe the outside of the battery with a damp cloth, and wipe clean the dust, oil, white powder, etc. on the panel and the pile head (that is, the positive and negative poles) that may cause leakage. In this way, the battery is often scrubbed, the pile head of the battery will not only not accumulate white acid powder, but also its service life will be longer.

6. Don't just replace the car with a battery with a larger capacity than the original battery. Because the power generation of car generators is fixed. If the battery is replaced with a large capacity battery, the new battery will be insufficiently charged, the car will not start smoothly, and the long-term loss of battery power will shorten the service life.

7. When using maintenance-free storage batteries, simply think that maintenance-free storage means that no maintenance is required. After over-discharge, it is not charged in time, and supplementary charging is not performed regularly, which affects the service life of the storage battery.

8. The battery should be firmly fixed on the car, and should be handled with care during installation and transportation.

9. When using the battery in winter, pay special attention to keeping it in a fully charged state to prevent freezing. When adding distilled water in winter, it should be done during charging to prevent freezing. The capacity of the battery will decrease in winter, and it is best to warm up the engine before starting. Due to the low temperature in winter, it will be difficult to charge the battery. You should always check the battery's storage status.

Car battery fault handling

When starting the car, uninterrupted use of the starter will cause the battery to be damaged due to over-discharge. The correct way to use it is that the total time to start the car each time is no more than 5 seconds, and the interval between restarts is no less than 15 seconds. In the case that the car still fails to start after multiple starts, the reason should be found from other aspects such as the circuit, the ignition coil or the oil circuit. If the battery cannot be started due to incorrect operation or a long time of inactivity, the battery should be replaced in time to save the battery, or the car should be started by means of wire borrowing.
