How to maintain a car battery.

1.For those who do not want to use the car for a long time, it is recommended to open the hood and unplug the positive pole of the battery to avoid power loss. After unplugging the positive pole, connect it when you need to use it.

2.Ordinary driving habits also determine the length of battery life, so after the vehicle is driven, before turning off the engine, turn off the air conditioner and then turn off the engine. The reason for this is that if you don't turn off the air conditioner before turning off the engine, when you need to use it again, the car starts all at once, and the air conditioner compressor.

It will work immediately, increasing the burden on the battery.

3.After the engine is turned off, reduce the long-term use of electrical appliances in the car, such as listening to the ** for a long time after turning off the engine, turning on the air conditioner fan, turning on the interior lighting or external headlights, these small habits will reduce the life of the battery.
