4.1 DC Power Plant Capacity Test (high-profile sites only)

Battery plants for high profile sites shall be load tested every five (5) years. The scheduling of load testing shall be the responsibility of the contractor, but the contractor shall work with STARNet to identify and test those sites which have gone the lonest without testing or have experienced anomolies worth investigating.

Perform the capacity test procedure as follows:

1. Equalize the batteries for 24 hours at the recommended voltage. (Consult manufacturer documentation for recommended equalization voltage.)

2. Return the batteries to float charge for a minimum of 3 days (maximum of 30 days) prior to the capacity test.

3. Measure and record the individual battery/cell float voltage.

4. Check battery connections to ensure proper resistance readings.

5. Check the temperature of several batteries to obtain an average battery temperature.

6. Disconnect the charging source.

7. Connect the load bank to the battery with the load bank off.

8. Start a timer and turn the load bank on.

9. Adjust the load bank to the appropriate discharge current. Maintain a constant discharge rate.

10. Record the individual battery or cell voltage at the beginning, regular intervals, and at the end of the test, with a minimum of 5 sets of readings.

11. Maintain the discharge rate until the voltage drops to a value equal to the specified minimum volts per cell times the number of cells.

12. At the conclusion of the test, determine the battery capacity.

Battery Capacity CalculationThe equation below is used to determine the battery system capacity.C = { Ta ÷ ( Ts × Kt ) } × 100C is the capacity.Ta is the actual test time to the specified minimum volts per cell value.Ts is the rated time to the specified minimum volts per cell value.Kt is the correction factor for the battery temperature at the start of the test.
