The device that converts chemical energy into electrical energy is called a chemical battery, generally abbreviated as a battery. After discharge, the internal active material can be charged-regenerated to store electrical energy as chemical energy; when it needs to be discharged, chemical energy is converted into electrical energy again. This kind of battery is called a storage battery. If there is a colloidal substance inside, we call it a colloidal battery. A battery is a substance in an electrochemical device that stores chemical capacity and releases electrical energy when necessary.

　　So what are the problems with car battery damage?

　　Damage to on-board electrical appliances: Unstable voltage has a great impact on electrical equipment (GPS, audio, etc.). It may even cause damage to the equipment.

　　Computer data loss: battery failure (power failure) will cause the data stored in the on-board computer to be lost, and the cost of re-unlocking is high.

　　Road failure: According to statistics, due to insufficient understanding of the importance of when to replace the battery, more than 80% of road failures are caused by the battery in car owners, which is time-consuming and laborious, and causes unnecessary additional expenses.
