Following activation, top up cells with distilled water only as necessary.
Replace vent caps and remove any spillage. If necessary, clean up spills
as outlined below. Do not add additional electrolyte after activation.
*Do not place on charge until electrolyte temperature is below 35°C (95°F).
BATTERY MAINTENANCE & STORAGE
Batteries should be kept clean at all times. If installed or stored in a dirty
location, regular cleaning should be performed. Before doing so, assure that
all the vent caps are tightly fastened. Using a solution of water and baking soda
(100g per litre), gently wipe the battery and terminals with a damp sponge,
then rinse with water.
A common cause of failure with flooded battery banks is poor maintenance.
Systems are often installed and then left to owners who are unaware of these
requirements or simply choose not to follow proper maintenance procedures.
To maintain cycle life and protect your investment, specific gravity of flooded
batteries should be checked regularly and cells topped up with distilled water
as needed. Often customers will neglect this for long periods of time and, when
doing so, over-water the cells resulting in loss of electrolyte, overflow during
charging and/or corrosion issues. Failing to top up cells may result in plate
exposure, overheating and possible explosion.
ELECTROLYTE - ADDING DISTILLED WATER
NOTE:
If the battery cells require watering more than once every two (2) months the
programmed charging voltages may be too high. Adjust and monitor accordingly. If a
particular cell requires significantly more water than others this may be a sign of charge
imbalance in the battery bank caused by resistance and/or cell failure.
TERMINALS
Inspection of battery terminal connections is also important. Loose connections may
result in ignition of hydrogen gases or cause a short, melting the terminals. It is important
to inspect, disconnect, clean and properly torque these connections on a regular basis.
CAUTION: Do not add water or electrolyte to cells before initial charging unless plates
are exposed. If so, add distilled water until plates are submerged. Please contact Rolls
Technical Support if you have any questions or concerns.
