Q: Will your product explode during use, or will the battery swell? Answer 1: Correct operation will not explode or battery swell. Answer 2: It is not improper operation. For example, the positive and negative poles of the clamp are connected reversely, the clamp is not fully clamped, the forced start is too large, or the forced start of a large displacement vehicle may cause the battery to burst or swell, but it will not cause spontaneous combustion. Or explode. If you do not understand the instructions, please contact us Question: Why does the battery clamp burn and melt? This is because the battery bears a high-intensity load, and the clamp is connected to the battery for too long, which causes the continuous start or forced start of the large-displacement car. There will be no safety issues, but it cannot be used again. Note: In order for your car to start smoothly, please make sure that the power of the car is above two bars every time you start the car!
