6.1.4. Degree check разряженности batteriesAt battery refusal in operation, and also at its service it is necessary to check разряженность the storage battery to accumulator rooms ареометром. Simultaneously it is necessary to measure and electrolit temperature to consider the temperature amendment to indications ареометра, specified in the table the Temperature amendment to indications ареометра at measurement of density of electrolit.
At electrolit temperature above 30 ° With amendment size increases to the actual indication ареометра. If electrolit temperature more low 20 ° With the amendment size is accordingly subtracted. When the temperature of electrolit within 20–30 ° With, the amendment on temperature is not entered.
After definition of density of electrolit in each element of the battery, its degree разряженности under the table electrolit Density is established at 25 ° With,/sm3 the Battery discharged more, than on 25 % in the winter and more, than on 50 % in the summer, remove from the car and recharge.
During density measurement watch that on a battery surface, the body and other details from a pipette did not fall the drops of electrolit containing sulfuric acid which causes corrosion, current leaks etc.
Not to receive wrong results, do not measure electrolit density:
– If its level does not correspond to norm;
– If electrolit too hot or cold; optimum temperatu-ra at measurement of density 15–27 ° With;
– After доливки the distilled water. It is necessary to wait, while the electrolit will mix up; if the battery is discharged, even some hours for this purpose can be demanded;
– After several inclusions of a starter. It is necessary to wait, that the uniform density of electrolit in a battery element was established;
– At "the boiling" electrolit. It is necessary to wait, while vials in the electrolit typed in a pipette ареометра, will rise on a surface.
