General
• Comes in factory filled, charged and ready to use.
• No topping up is required.
• Spill-proof and Leak-proof.
• User friendly and explosion proof.
• Easy to install and environment friendly.
• Flame retardant containers.
Monthly check
• Check the float/charge settings of the P/P.
• Float Voltage:
• 2.23 volt/cell or 53.5 volt at SMPS output.
• Charge Voltage:
• 2.3 volt/cell or 55.2 volt at SMPS on Charge Mode.
Quarterly check
• Discharge the battery with equipment load for 15 minutes
by switching of the P/P.
• Note down the individual cell readings.
• If the average cell voltage is greater than 2.0 volt, then
the cells falling below by 0.03 volt of the average cell voltage are
considered weak.
• If the average cell voltage is lesser than 2.0 volts then
the cells falling below by 0.1 volt of the average cell voltage are
considered weak.
• Focus on the identified weak cells.
Actions to be taken
• Ensure the tightness of the terminals.
• Check for any terminal post corrosion.
• If corrosion is observed,disconnect the battery and clean
the terminal connectors and bolts with a brass brush or emery paper.
• Reconnect the battery and have a charge discharge cycle.
• If no improvement, replace the cell.
Half yearly check
• Ensure the tightness of the battery terminals.
• Check for the terminal post corrosion.
• If corrosion is observed,clean the affected area as follows:
1. Disconnect the battery bank from the circuit and remove the affected
terminal connectors
2. Clean the terminal with a brass brush or emery paper.
3. Reconnect the connectors and apply a thin layer of petroleum jelly.
Annual check
• In addition to the above checks,once a year TEST DISCAHRGE
of the battery to be carried out to determine the health of the battery.
1. Charge the battery at a constant voltage of 2.3 volt per cell or
55.2 volt at charge mode for 48 hours with a current limitation of
20% of the rated capacity.
2. Then discharge the battery at 10 hour rate. If the battery is 600
AH the discharge current to be 60 Amps
Annual check….
3. The discharge is to be stopped when the total voltage across the
bank falls to 42 volt or any one of the cell goes to 1.75 volt.
4. Normally 10 hours of discharge is expected and the capacity of
the cell is 100% rated capacity.
5. Requirement: The actual capacity shall not be less than 90% of
the rated capacity.
