Electrolyte Level, Checking

Electrolyte Level, Checking

Procedure

Maintaining the correct electrolyte level in the battery is an important factor affecting the length of the battery's service life.


Risk of injury from direct exposure to battery acid.

• Follow accident prevention regulations when working with battery acid. Refer to=> [ There is a risk of injury from
the battery acid. ] Lead-Acid Battery Warnings and Safety Precautions.

• Wear protective eyewear and clothing. Refer to=> [ Protect against injury by using
protective eyewear and clothing. ] Lead-Acid Battery Warnings and Safety Precautions.

Risk of explosion due to open flame, fire and smoking.

• Only illuminate the inside of the battery housing with a flashlight.

• Never illuminate the inside of the battery housing with an open flame.

• Never handle open flame or burning cigarettes near batteries.

- If the "Min" and "Max" marking on the outside of the battery can be seen, simply inspect by sight.

• The electrolyte level must be above the "Min" marking but must only go as high as the "Max" marking.

- If it is difficult to see the "Min" and "Max" markings on the outside of the battery or they cannot be seen because the battery housing is opaque, remove the sealing plugs.

- Check electrolyte level by visually checking the inside of the battery.

• The electrolyte level must coincide with the internal level mark (plastic web). This corresponds to the outer "max" marking.


Risk of corrosion due to leaking battery acid.

• To ensure that the various battery connection systems are free of leaks, the battery's original sealing plugs must be installed in the battery openings. Only replace missing or damaged sealing plugs with the same type of original plugs.

• The sealing plugs must be equipped with an O-ring.

• If the acid level is too low, the battery must be replaced. Do not add distilled water.

- Screw in the sealing plugs of battery cells.
