To prevent oxidation of the battery terminals and wire lugs, regularly clean and lubricate them with petroleum jelly. Watch tightness of connection of tips of wires and conclusions of the battery.
Helpful Hint: Commercially available copper-containing lubricants can be used instead of petroleum jelly to protect terminals and lugs from oxidation.
Periodically check the reliability of the battery mounting on the car and tighten it if necessary to avoid cracking the monoblock and losing the battery.
Helpful Hint: To reduce vibrations transmitted to the battery monobloc, place the battery on an acid-resistant rubber mat.
The wires connected to the battery must not be overtightened, which will lead to loosening of the terminals in the cover and electrolyte leakage.
Periodically, at least once every 2 weeks, check the electrolyte level in the battery cells (if the vehicle has a serviceable battery).
Note: For batteries with a common cover for all cells, equipped with a capacitor cavity, it is allowed to check the electrolyte level once every 2 months.
The electrolyte level in all cells should be 5-10 mm higher than the upper edge of the separators, which corresponds to the level between the marks «MIN» And «MAX» on the wall of the translucent battery case.
Helpful advice: It is convenient to check the electrolyte level above the upper edge of the separators with a glass tube: lower it into the cell until it stops in the separator and, closing the free end of the tube with your finger, remove it from the cell.
To restore the electrolyte level, add only distilled water. If it is determined that sloshing is the cause of the low level, then add electrolyte of the same density as that left in the battery cell. If the level is above normal, pump out the electrolyte with a rubber bulb with an ebonite tip.
Warning: It is strictly forbidden to add concentrated acid to the battery!
