Bringing a dry-charged battery into working condition (VAZ-1111)

Spare parts for batteries are supplied (mostly) without electrolyte in a dry-charged version. To bring such a battery into working condition, remove the technological plugs or sealing tape. Then, with a small stream, through a funnel (glass or acid-resistant plastic) fill the battery with electrolyte with a density (reduced to 25°C) of 1.28 g/cm³ for regions with a moderate climate and 1.23 g/cm³ for the tropics. 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 is checked without load.

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 more 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 V, 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.
