Checking the state of charge of the battery

The density of the electrolyte in conjunction with the measurement of the voltage at the battery terminals allow us to make an accurate conclusion about the state of charge of the battery. To test serves as a hydrometer, which can be purchased in a specialty store. The greater the density of the electrolyte, the more rises (float) float hydrometer. On hydrometer scale values expressed in terms of density ^(kg / cm3).

During the measurement of the density of the electrolyte follow so that the surface of the battery box and other details from a pipette hydrometer not falling droplets of electrolyte containing sulfuric acid, which causes corrosion and leakage.

The density of the electrolyte in a fully charged battery is 1.28 g / cm ^3.

The density of the electrolyte in the battery discharged by 25%, is 1.24 g / cm ^3.

The density of the electrolyte in the battery discharged to 50%, is 1.20 g / ^cm 3.

Battery, discharged more than 25% in winter and more than 50% in the summer, remove from the car and recharge.

In measuring the density of the electrolyte of the electrolyte temperature must be between 20-30 ?� C. The density of the electrolyte should be measured in each element (bank) battery. After measuring the density of the electrolyte can set the degree of discharge of the battery.

All the elements of the electrolyte should be of the same density.

The density of the electrolyte in a fully charged battery is 1.28 g / cm ^3.

The density of the electrolyte secondary battery discharged by 25% is 1.24g / ^cm 3.

The density of the electrolyte secondary battery discharged by 50%, is 1.20 g / ^cm 3.

Battery, discharged more than 25% in winter and more than 50% in the summer, remove from the car and recharge.
