Bringing a dry-charged battery into working condition

Batteries are delivered to 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, with a small stream through a funnel, pour electrolyte into the battery with a density (reduced to 25°С) 1.28 g/cm³ for temperate regions. Battery conditioning operations must be carried out at ambient temperature (25±10) °C.

Soak the battery for 20 minutes so that the plates and separators are saturated with electrolyte. Then check the battery voltage with no load. If the voltage is at least 1.25 V, then it is ready for operation. At voltages 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 V, the battery is rejected.

Be sure to charge the battery after filling with electrolyte if it has been stored for more than 12 months from the date of manufacture, or if the battery will be initially used under severe conditions: cold weather, 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 normal by adding electrolyte of the same density as at the beginning of filling.
