Periodic Evaluation
Upon replacement of a battery, all interconnect hardware should be replaced at the same time.
To keep track of performance and identify batteries that may be approaching the end of their
life, perform the following tests during on a quarterly basis following commissioning (see page
13). Tests must be made with a high-quality digital meter. Voltages must be measured directly
on battery terminals, not on other conductors. All connections must be cleaned, re-tightened,
and re-torqued before testing. If a battery fails any test, it may be defective. If this occurs under
the conditions of the warranty, the battery will be replaced according to the warranty terms.
Bring the batteries to a full state of charge before performing the following test.
Monthly Battery Inspection
o General appearance and cleanliness of battery, battery rack and battery area.
Inspect for contamination by dust.
Inspect for loose or corroded connections.
If necessary, isolate the string/battery and clean with a damp soft cloth. Do not use solvents or
scouring powders to clean the batteries.
o Cracks in cell containers or leakage of electrolyte.
o Any evidence of corrosion at cell terminals, connectors or racks.
o Ambient temperature and condition of ventilation equipment.
o Current and voltage during charge cycle. Measure individual battery voltages at the battery terminal.
The measurements should be within 5% of the average.
o Voltage at end of charge cycle. Measure individual battery voltages at the battery terminal.
The measurements should be within 5% of the average.
o End of discharge voltage measured at the battery. Measure individual battery voltages at the battery
terminal. The measurements should be within 5% of the average.
o Record findings clearly. List the dates for all entries.
Quarterly Battery Inspection
This should include the monthly observations, plus:
o End of charge voltage of every cell and battery terminal voltage measured at battery.
o End of discharge voltage of every cell and battery terminal voltage measured at battery.
o Electrolyte temperature in representative cell(s), typically one cell/tier distributed throughout battery.
o Record findings clearly. List the dates for all entries.
Annual Battery Inspection
This should include the monthly and quarterly observations, plus:
o Inter-cell / inter-unit connection integrity.
o Retighten terminals to specified torque values. See page 25 for specifications.
o Record findings clearly. List the dates for all entries.
o Perform an equalization (see page 16 for details).
