Bringing a dry-charged battery into working condition (VAZ-2108)

Batteries are supplied as spare parts without electrolyte in a dry-charged version. To bring such a battery into working condition, unscrew the plugs and remove the seals from them or cut off the ventilation protrusions. Then, electrolyte with a density (reduced to 25°C) of 1.27-1.29 g/cm³ for regions with a moderate climate or 1.22-1.24 g/cm³ for the tropics is poured into the battery in a small stream through a funnel. Operations to bring the battery into working condition must be carried out at an ambient temperature of (25±10)°C.

The battery is kept for 20 minutes so that the plates and separators are saturated with electrolyte. Then the battery voltage without load and the density of the electrolyte are checked.

If the battery voltage is at least 12.5 V, it is ready for operation. If the voltage is less than 12.5 V but greater than 10.5 V, the battery must be recharged to the voltage specified by the manufacturer. If the voltage is less than or equal to 10.5, the battery is rejected.

It is necessary to charge the battery after filling it with electrolyte if it has been stored for more than 12 months from the date of manufacture or if the initial use of the battery will take place in difficult conditions: in cold weather, with frequent engine starts, etc.

As a result of impregnation of separators and plates, the electrolyte level in the battery will inevitably decrease. Therefore, before installing the battery on the car, bring the level to the norm by adding electrolyte of the same density as at the beginning of filling.
