YHZC series surge protector (Surge Protective Device, referred to as SPD) is an electronic device that provides safety protection for various electronic equipment, instruments and communication lines. When a spike current or voltage suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and shunt in a very short time, thereby preventing the surge from damaging other devices in the circuit. Surges are generated from a wide range of sources, such as lightning induction, switch operation, electrostatic discharge, etc.

The normal self-discharge of a battery is due to the structural factors of the battery itself, such as impurities in the electrolyte, the presence of contaminants, or the partial detachment of active materials inside the battery, which settle at the bottom, causing the positive and negative plates to discharge through sedimentation. If a battery is not used for a long time, it will slowly discharge on its own; therefore, the car should be started periodically to charge the battery.
