Electrolyte Specific Gravity Check

PROCEDURE

1. Удельный вес аккумуляторного электролита изменяется с температурой. Повышение

1. Battery electrolyte specific gravity changes with temperature. An increase in temperature decreases specific gravity, and vice versa.

2. Удельный вес электролита полностью заряженной аккумуляторной батареи должен

2. The specific gravity of electrolyte in a fully charged battery should be between 1.260 and 1.280 at 27 °C. Correct the specific gravity by adding 0.04 points for every 5.6 °C above 27 °C, or by subtracting 0.04 points for every 5.6 °C below 27 °C.

Например:

For example:

Hydrometer reading – 1.280 at 5.6 °C.

Correct the specific gravity by 0.028 points according to the temperature difference. The true specific gravity is 1.252.
1.280–0.028=1.252

A difference of 50 points or more in electrolyte specific gravity between battery cells indicates that the battery is faulty and must be replaced.
