Pay attention to the following points when adding electrolyte or water to the battery:
The electrolyte can be 10 to 15 mm 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. The electrolyte is conductive. Once it flows between the positive and negative poles of the battery, it will form a loop self discharge. 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.
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 replenished in time, it may shorten the service life of the battery. Distilled water should be replenished in time, and drinking purified water should not be used instead. Because pure water contains a variety of trace elements, it will have an adverse impact on the battery.
