What should be done after the battery is frozen? The following is the analysis of the cause of battery icing and general treatment methods.
Analysis of the cause of battery icing:
(1) The battery has a low specific gravity when it leaves the factory. The electrolyte reached a freezing point when used in cold areas.
(2) After the battery is over-discharged, the specific gravity of the electrolyte drops more, but it is not charged in time.
(3) The electrolyte liquid level is too low. After adding distilled water, the engine is not operated for a certain period of time, so that the upper and lower specific gravity of the electrolyte are inconsistent, and stratification occurs.
General treatment method:
The icy battery should be moved to a warm room to let it melt slowly; then charge the battery with 1/3 of the specified charging current, continuously observe the cell voltage and electrolyte temperature, and the specific gravity of the electrolyte should reach 1.28 g after charging. /cm3, if not in compliance, adjust with distilled water or sulfuric acid with a specific gravity of 1.40 g/cm3.
