11.4.2. Check of a technical ostoyaniye of the rechargeable battery The condition of the rechargeable battery which is characterized by degree of its state of charge needs to be checked at least once a quarter, and also at the become frequent cases of unreliable start of the engine on electrolyte density, at the same time measuring its temperature to consider the temperature amendment specified in the tab. Temperature amendment to the indication of a densimetr.
After determination of density of electrolyte in the rechargeable battery by means of a densimetr (areometer) or the indicator, follows taking into account the initial density of electrolyte of completely charged battery found for this climatic zone according to the tab. Electrolyte density for various climatic areas
to establish degree of its razryazhennost according to the tab. Definition of degree of state of charge of the rechargeable battery.
At a temperature of electrolyte above 30 °C the size of the amendment increases to the actual indication of a densimetr, at a temperature below 20 °C – is subtracted. The amendment is not entered at a temperature of electrolyte within 20-30 °C.
Electrolyte density in separate elements of the serviceable battery should not differ more than on 0,01 g/cm3.
The battery discharged more than for 25% in the winter and more than for 50% in the summer should be laid off and put on charging.
