The traditional 12V car battery uses a lead-calcium alloy as the grid, so the amount of water decomposition generated during charging is very small, so the amount of water evaporation is also low, and the outer shell is sealed, and the sulfuric acid gas released is also very small, so it can There is no need to add any liquid during the life cycle, so it has the advantages of long power storage time and maintenance-free. The structure mainly consists of positive and negative plates, separators, electrolyte, tank shell, connecting strips and pole piles.

A car battery is a device that converts chemical energy into electrical energy. It is a DC power source. Its functions are as follows:

(1) When starting the engine, provide powerful starting current to the starter.

(2) When the generator is overloaded when the engine is running, it can assist the generator to supply power to the electrical equipment. When the voltage of the generator terminal is higher than the voltage of the lead battery, the electrical energy is converted into chemical energy and stored, that is, the battery can be charged.

(3) When the engine is in the off state, supply power to the electrical equipment.

(4) The battery is also a large-capacity capacitor, which can protect the car's electrical appliances from voltage fluctuations.

Chinese car battery manufacturers have a one-year warranty. The manufacturer’s design life is generally 2 to 3 years. Family cars are relatively economical. Many new car batteries can be used for 4 years or more, but taxis and operating vehicles can last for more than a year. Up. So as long as you pay attention to avoid the following points, the service life of the battery will increase accordingly.

1: No excessive discharge

2: The vehicle cannot be opened for a long time
