Maintenance and maintenance of car battery

1) The electrolyte level should always be kept between max and min, check once a month, and depending on the drop of the level, add distilled water (pure water) appropriately, do not add acid.　　 (2) When the battery voltage is insufficient, the light is dim, and the starting is weak, the vehicle should be charged outside in time.　　 (3) Prevent the battery from overcharging or long-term loss of electricity. Overcharging will cause the active material to fall off, and the loss of electricity will vulcanize the plates. Make sure that the regulator voltage cannot be too high or too low.　　 (4) During use, always check whether the vent is unblocked to prevent the battery from deforming or bursting.　　 (5) The battery should be kept away from heat sources and open flames, and should be ventilated during charging and use to prevent burns and injury.　　 (6) To prevent the battery from discharging with high current for a long time, the start-up time should not be more than 5 seconds each time, and the two consecutive start-up time should be 10-15 seconds apart.　　 (7) The battery should be installed firmly in the car to reduce vibration.　　 (8) Always check whether the battery connection line is firm. All the live connectors must be in good contact to prevent sparks and explosion of the battery. The oxides and sulfates produced by the battery clips must be scraped off and coated with petroleum jelly to prevent further corrosion.　　 (9) Frequently remove dust and dirt on the battery cover and spilled electrolyte, keep it clean and dry, and prevent self-discharge.　　 (10) The cracking of the sealing glue should be repaired in time.　　 (11) When a car is driving in a cold area, it is necessary to prevent the battery from completely discharging to prevent the electrolyte from freezing.
