To prevent oxidation of battery terminals and wire tips, clean them regularly and lubricate them with petroleum jelly. Make sure that the wire tips and battery terminals are tightly connected.
Helpful Hint: Instead of technical petroleum jelly, you can use commercially available copper-containing greases to protect terminals and tips from oxidation.
Periodically check the reliability of the battery mount on the vehicle and tighten it if necessary to avoid cracks in the monoblock and loss of the battery.
Helpful Hint: To reduce vibrations transmitted to the battery monoblock, place the battery on an acid-resistant rubber mat.
The wires connected to the battery should not be overly taut, which will cause the terminals in the cover to become loose and electrolyte to leak.
Periodically, at least once every 2 weeks, check the electrolyte level in the battery cells (if the vehicle is equipped with a serviceable battery).
Note: For batteries with a common cover for all elements, equipped with a capacitor cavity, it is permissible to check the electrolyte level once every 2 months.
The electrolyte level in all elements should be 5-10 mm above the upper edge of the separators, which corresponds to the level being between the "MIN" and "MAX" marks 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 using a glass tube: lower it into the element until it stops in the separator and, closing the free end of the tube with your finger, remove it from the element.
To restore the electrolyte level, add only distilled water. If it is definitely established that the cause of the low level is splashing, then add electrolyte of the same density as the one remaining in the battery element. If the level is above the norm, pump out the electrolyte with a rubber bulb with an ebonite tip.
Warning: It is strictly forbidden to add concentrated acid to the battery!
