In the process of battery charging and discharging, the water in the electrolyte will gradually decrease due to electrolysis and evaporation, resulting in the decline of electrolytic liquid level. If it is not supplemented in time, it may shorten the service life of the battery, and distilled water should be supplemented in time. Do not use drinking purified water instead, because purified water contains a variety of trace elements, which will have an adverse impact on the battery.
When adding electrolyte or water to the battery, pay attention to that the electrolyte is 10-15mm higher than the electrode plate; For batteries with two red lines, the electrolyte shall not exceed the upper red line. If the electrolyte is too full, it will overflow from the small hole of the battery cover. Once it flows between the positive and negative poles of the battery, a loop self discharge will be formed. In this case, the electrolyte should be wiped off or washed with boiling water.
When adding electrolyte, if something falls in accidentally, do not use metal objects to fish out, and use wooden sticks to clamp out impurities; If iron wire or copper wire is used for fishing, metal molecules will enter the battery under the corrosion of sulfuric acid to form self discharge and damage the battery.
If the vehicle stops running for more than 20 days, the negative wire of the battery should be removed to avoid leakage accidents.
