General Maintenance
Water Levels Flooded lead acid batteries require periodic water refills in each battery
cell. Only distilled water should be used in a battery, as tap or mineral
water may contain contaminants which will upset the battery chemistry
and may damage the battery.
When filling the battery, clean the surface first to prevent dirt from
entering the cell. Fill the cell to just above the plates or to the bottom of
the internal collar inside the battery. Never fill the cells to the top or acid
will leak out during charging.
Check the water level in the batteries frequently when performing an
equalize charge and add water if necessary. Always follow the safety
steps covered in the front of the manual.
Battery Cables and
Posts Battery posts must be clean to reduce the resistance between the battery
post and cable connection. A buildup of dirt or oxidation may eventually
lead to the cable terminal overheating during periods of high current draw.
Use a stiff wire brush and remove all dirt and corrosion from the battery
terminals and cables. Use an alkaline solution of baking soda and water to
clean the terminals and neutralize any battery acid on the terminals or
cable lugs.
Torque Battery
Connections After the terminals are clean, reassemble the cable to the battery terminal
and torque the connections to the battery manufacturer’s
recommendations.
Coat the battery terminals with an antioxidant compound.
WARNING: Shock Hazard
Before attempting to clean the battery posts, turn off the DC circuit breaker. Use
only insulated tools and remove all jewellery.
CAUTION: Damage to Batteries
Never let a baking soda solution get into the battery as it will neutralize the acid
resulting in permanent damage.
