Battery charge (VAZ-2121)

After removing the battery from the vehicle, carefully clean it, especially the top 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 electrolyte density sometimes differs from the norm. In this case, bring it to the recommended value.

If the density is high, remove some of the electrolyte from the element, add distilled water, wait until the electrolyte mixes and measure the density again.

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