Execution order
1.The specific gravity of 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. Correction of the specific gravity should be made by adding 0.04 points for every 5.56°C above 26.7°C or by subtracting 0.04 points for every 5.56°C below 26.7°C.
For example: Hydrometer reading is 1.280 at a temperature of 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 the specific gravity of the electrolyte of 50 or more points between the cells of the battery indicates that the battery is faulty and must be replaced.
