1. The car battery is exhausted and its lifespan is reduced by 80%. If it has been used for a year and is fundamentally broken, replace it directly.
2. If the battery is turned off or the voltage is too low, it will cause data loss and require initialization, commonly called decoding or pairing. Even if you replace the battery yourself, this won't happen. can be used normally due to some problems. It is best to ask 4S for help.
3. Use the battery normally and save electricity. The general lifespan can reach more than 3 years. If the battery power is insufficient, charge it in time.
4. When the battery power is less than half, that is, when the voltage is lower than 13.4V, the battery fault light will light up and it is difficult to start the car. It must be charged. The engine ofmust be charged at more than 1,500 rpm for more than 20 minutes. It can be started once, continue charging at over 1500 RPM for over 30 minutes and it can be started once the next day.
5. If the battery voltage is 10% lower than the rated voltage, i.e. less than 10.8V, the battery life will be reduced by 80%. time, you can also use a charger to charge to avoid power loss.
