10.3.7.2 Battery checking and care
Even “maintenance-free” batteries need a degree of care to maintain their maximum operational
life.
The outside of the battery and the terminals should be cleaned regularly with a soft cloth.
This avoids current leaks and minimizes the discharge rate.
Material Terminal grease
Distilled water
Cleaning cloth
Protective gloves
Eye protection
Precondition The machine is shut down.
The machine is standing level.
The machine is fully vented, the pressure gauge reads 0 psig.
The machine is cooled down.
➤ Open the canopy.
1.
Clean the casing and terminals. Do not use a wire brush!
2. Lightly grease the terminals to prevent corrosion.
3. Check that the batteries and cable connections are properly seated and tighten if necessary.
Check the battery electrolyte level
The fluid is generally sufficient for the life of the battery. Nevertheless, the fluid level should be
checked annually. The level should be up to the mark, 0.4 inches above the plates.
Replace the battery immediately if the casing leaks.
