How to prevent the battery electrolyte from freezing?

Proper use and timely maintenance of the battery can keep the battery in a good technical state, prolong its service life, and ensure the reliability of work at the same time. In order to prevent the electrolyte from freezing in cold areas, the following measures can be taken for daily maintenance; (1) Regularly measure the relative density of the electrolyte. If it is found that it does not meet the local climate requirements, it must be adjusted in time. (2) Keep the battery in a fully charged state. If one of the following phenomena occurs, supplementary charging must be performed: ① When the relative density of the electrolyte drops below 1.20. ②When the discharge exceeds 25% in winter and 50% in summer, ③When the light is dimmer than usual, it means that the power is insufficient. ④ When the engine is weak at starting (not a mechanical failure) (3) If the electrolyte level is too low and distilled water needs to be added, the distilled water can only be added before charging, and the water and electrolyte should be mixed as soon as possible to reduce electrolysis The possibility of liquid freezing. (4) Sulfuric acid and non-distilled water for general industrial use are not allowed. Impurities in them will cause the battery to discharge by itself, reduce the capacity of the battery, corrode the plates, and shorten the service life of the plates. In addition, if the density of the electrolyte is too low, it is easy to freeze in cold areas. (5) When the temperature is lower than -30℃, in order to prevent the electrolyte from freezing, the battery can be removed and placed indoors.
