Car battery is the main source of other electric energy of the car, and it is necessary to check the battery in daily life.

Check the external battery: the shell should be no large cracks, no leakage; surface should be clean, no corrosion, positive electrode wire (wire) should be insulated well, otherwise it will produce self discharge phenomenon; joints should be no loose, grounding should be reliable, otherwise output impedance will increase, reduce output power rate. Open the headlights for inspection. If the light is white, it indicates that the battery is normal; if the lights are red and dark, the power shortage is indicated. Connect the starter, if the normal speed, lights, though slightly darker, but there is still enough brightness, good battery, charging is sufficient; if the starter is weak and lights to become very dark, that excessive battery discharge, should immediately charge.

Battery routine maintenance should pay attention to the following points:

1 electrolyte liquid level should always be maintained between Max and min, the monthly check once, and depending on the level of the liquid level, add distilled water (pure water), do not add acid.

2 when the battery voltage is insufficient and the light is dim, the starting weakness, should carry on the vehicle outside the charge promptly.

3. To prevent the battery from overcharging or long-term loss of electricity, overcharge will make active material shedding, lose electricity plate curing, to ensure the regulation voltage can not be too high or too low.

4 the use of the process, should always check the exhaust port is open, in order to prevent battery deformation or burst.

5 battery should be far away from heat and fire, charging and use should be kept ventilation, in order to prevent burning injury.

6 to prevent the battery long time high current discharge, each time using the starting time can not be more than 5 seconds, the two time to start the time, the middle interval 10-1 5 seconds.

7 battery installed in the car should be strong, reduce vibration.

8 often check the battery connection line is solid, all live joints, must maintain good contact, to prevent the generation of sparks, causing the battery explosion. The battery clip produces oxides, sulfate, must be scraped, and coated with Vaseline, to prevent further corrosion.

9 often remove the battery cover on the dirt and the spill of the electrolyte, to keep clean and dry, to prevent self discharge.

10 sealing plastic cracking should be repaired in time.

11 car driving in the cold, to avoid the battery fully discharge, so as to avoid freezing electrolyte.
