Order of execution
1.The specific gravity of the battery electrolyte changes with temperature. An increase in temperature leads to a decrease in specific gravity and vice versa.
2.The specific gravity of the electrolyte of a fully charged battery should be between 1.260 and 1.280, at a temperature of 26.7°C. The specific gravity adjustment should be made by adding 0.04 points for every 5.56°C above 26.7°C or subtracting 0.04 points for every 5.56°C below 26.7°C.
Example: Hydrometer reads 1.280 at 5.56°C.
According to the temperature difference, it is necessary to correct the specific gravity by 0.028 points. The true specific gravity is 1.252.
1,280–0,028=1,252
Warning! A difference in electrolyte specific gravity of 50 points or more between battery cells indicates that the battery is defective and needs to be replaced.
