Batteries are an indispensable part of the car and can be divided into traditional lead-acid batteries and maintenance-free batteries. Since the battery uses lead-calcium alloy as the grid frame, the amount of water decomposition generated during charging is less, the amount of water evaporation is also low, and the shell adopts a sealed structure, which releases very little sulfuric acid gas. Therefore, compared with traditional batteries, it has the advantages of no need to add any liquid, long storage time for wiring piles, and so on.

The design life of the battery is 27 months. Generally, family cars are more economical. Many new car batteries are used for 3-4 years, but they must be replaced in about 2 years after being replaced once. Taxi comparison fees, single bus can be used for a year, and double bus can be used for about 8-10 months.

The factors that affect the battery life are: vehicle condition, road conditions, and driver's habits

Generally, the newer the car, the more the battery is saved, because the motor is easy to use and the battery is saved, and the generator is easy to use. The battery can be fully charged. After the car is old, especially after the two large motors and generators are replaced, due to the huge price difference between the original and refurbished goods of these two products on the market, it is easy for car owners not to replace the original parts, and then the battery is more likely to break. Often off-road batteries are easy to break, and car batteries have a technical indicator to indicate the anti-vibration performance of the battery! If the working environment is not good, the battery that meets the standards vibrates frequently, of course it loves to break.
