How to make car batteries more durable


The service life of a car battery depends on the structure and quality of the battery on the one hand, and is closely related to the daily maintenance on the other hand, so we should do the following in use:

1. Pay attention to firm installation and clean maintenance
First of all, the installation of the battery on the car should be firm and reliable to prevent the vibration of the car from causing damage to the battery’s internal plates and loose connection of external wires. Secondly, the starting battery for automobiles can withstand high current and short time discharge, but long time discharge at low current will reduce the battery life; therefore, the dust, mud and water on the battery, as well as the oxide and liquid on the terminal and thread should be removed frequently Keep the electrolyte overflowing from the mouth clean and dry to prevent the battery from self-discharging.

2. Pay attention to charging in time
When the battery voltage is insufficient, the light is dim, and the starting is weak, supplementary charging should be carried out outside the car in time. The storage capacity of the battery can be reflected on the dashboard. When the ammeter pointer shows that the storage capacity is less than about one-third of the discharge, it is necessary to charge it in time, and the discharge is more than two-thirds as over-discharge. During overdischarge charging, the current is relatively large, which is not conducive to the reduction of active materials. Sometimes it is found that the battery is not enough on the road, and the engine cannot be started. As a temporary measure, you can ask other vehicles for help. When the car is driving in a cold area, avoid the battery from completely discharging to prevent the electrolyte from freezing.

3. Regular inspection
a. Check for cracks and electrolyte leakage in the battery shell.
b. Frequently check whether the battery connection line is firm, and all the live connectors must be in good contact to prevent sparks and explosion of the battery. For example, always check whether the fixing bolts of the battery on the bracket are tightened, and always check whether the pole and the terminal are connected reliably; do not put metal objects on the battery to prevent short circuits; repair the cracking of the sealing glue in time. Check each part of the circuit for aging or short circuit.
c. Regularly check the battery electrolyte density and liquid level, check the battery discharge degree, and prevent early retirement due to over-discharge.
d. Pay attention to keeping the battery charging circuit normal. When the battery is overused, the charging indicator may not correctly display whether the charging is normal or not. The following methods can be used: keep the car at idle at night, turn on the headlights, and illuminate Go to a certain fixed position, stare at the center of the light and look carefully, and then add fuel quickly to see if the light suddenly turns bright, which indicates that the generator and the charging circuit are normal.
e. Cars should be parked temporarily to prevent exposure to the sun in summer, and to prevent freezing in winter. When the car is parked for a long time, the engine should be started and run at medium speed for more than half an hour for more than half a month; it is best to remove the battery and store it separately for long-term parking.
