Battery charge

Carefully clean the battery removed from the vehicle, especially its upper part, and check the electrolyte level.

The battery is charged with a current of 5.5 A for several hours until the voltage becomes constant and the electrolysis plane remains unchanged.

At the end of the charge, the density of the electrolyte sometimes differs from the norm. In this case, bring it to the recommended value.

If the density is increased, remove some of the electrolyte from the cell, add distilled water, wait until the electrolyte is mixed and measure the density again.

If the density of the electrolyte is below normal, then after removing it from the cell, add electrolyte of increased density (1.4 g/cm³). After adjusting the density of the electrolyte, continue charging the battery for another 30 minutes to mix the electrolyte. Then disconnect the battery and after 30 minutes measure its level in all elements. If the electrolyte level is below normal, then add electrolyte with a density corresponding to the given climatic region (see table. 7-3). If the electrolyte level is above normal, remove its excess with a rubber bulb.
