Periodic Evaluation
Upon replacement of a battery (or string), 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 terms of the warranty.
Bring the batteries to a full state of charge before performing either of the following tests.
24-Hour Open-Circuit Test
Remove all battery connections, then allow the battery to rest in this state for 24 hours.
Test the battery voltage, compensating for temperature. The EnergyCell PLR should measure
12.8 Vdc. A battery below 12.6 Vdc has lost capacity and may need to be replaced.
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.
NOTE
: The batteries should be equalized on a monthly basis as noted on page 14.
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 Temperature of electrolyte in representative cell(s), typically one cell/tier distributed throughout
the battery.
o Record findings clearly. List the dates for all entries.
