Battery life cycle is generally 3 years or so, after use, it is recommended to turn off the electric equipment on some cars in time, such as headlights and sound, because the vehicle can not charge the battery after flameout, so it will cause battery loss, will reduce battery life. In general, our normal car, the life of the car battery is about 3 years.

The more times the battery is supplied, the greater the load and the longer the time, the shorter the service life will be. After the car flameout is not completely power off, the battery power of the car will be excessive consumption, it is likely to be difficult to start the vehicle, which also reduces the service life of the battery.

First, human trolley power start, application: more people can push the car, simple money saving but time-consuming and laborious, this is the simplest method, I believe we have seen in real life.
