7.2.1.1. Check of degree of a zaryazhennost of the battery

Electrolit density together with tension measurement on conclusions of the storage battery allow to draw an exact conclusion on degree of a zaryazhennost of the battery. For check the areometer which can be got in specialized shop serves. The enough of electrolit, the rises more the areometer float (emerges). On a scale of the areometer of value are expressed in terms of density ^(kg/cm3).

During measurement of density of electrolit watch that on a battery surface, the body and other details from a pipette of the areometer did not fall the drops of electrolit containing sulfuric acid which causes corrosion and leakages of a current.

The electrolit density in completely charged storage battery makes 1,28 ^g/cm3.

The electrolit density in the storage battery discharged for 25 %, makes 1,24 ^g/cm3.

The electrolit density in the storage battery discharged for 50 %, makes 1,20 ^g/cm3.

The storage battery discharged more than for 25 % in the winter and more than for 50 % in the summer, remove from the car and recharge.

At measurement of density of electrolit the temperature of electrolit should be in limits of 20-30 °C. The density of electrolit should be measured in each element (bank) of the storage battery. After measurement of density of electrolit it is possible establish degree of a razryazhennost of the battery.

In all elements of electrolits should have identical density.

The electrolit density in completely charged storage battery makes 1,28 ^g/cm3.

The electrolit density to the storage battery discharged for 25 %, makes 1,24 ^g/cm3.

The electrolit density to the storage battery discharged for 50 %, makes 1,20 ^g/cm3.

The storage battery discharged more than for 25 % in the winter and more than for 50 % in the summer, remove from the car and recharge.
