When starting the car, if the first start is unsuccessful, it means that the battery loss is serious, at this time, if you need to start the second and third time, you need an interval of more than 30 seconds, the start button can not be long pressed or used continuously without interval, otherwise it will lead to excessive current and battery heating.

2. Battery clamps must be inserted into the machine and clamped in place to avoid artificially causing the host starter port to melt.

3. Take down the battery clip normally after starting the car.
