4.1 Recommended Maintenance Tasks
In order to prolong battery life, perform regular maintenance and inspections.
Monthly Maintenance
Keep the batteries and battery room clean.
•
Measure and record the ambient temperature of the battery-room.
•
Check for damage and overheating evidence on the terminal, container, and lid.
•
Measure and record the total voltage and floating current of the battery system.
•
Quarterly Maintenance
Measure and record the floating voltage of every on-line battery. If the voltage of
more than two cells is less than 13.0V after temperature adjustment, discharge the
battery and then recharge at the float rate. If the problem still exists, conduct yearly
or three-year maintenance procedures. If the problem persists, please contact Alpha
Technologies.
Yearly Maintenance
Check for loose connections.
•
Conduct a discharge test to check the exact load, discharging 30-40% of the
•
rated capacity.
Three-Year Maintenance
After three years of operation, conduct an 80% capacity test annually.
