Battery Preventive Maintenance Procedure

The purpose of the preventive maintenance is to ensure that the battery is in good, working condition. The observations, measurements, and tests performed are designed to determine the “state of health” of the battery. It will also allow for the prediction of future performance and preempt possible failure.

1.Measure the float charge voltage.

a.At the power bay bus.

b.At the battery.

c.Reset voltage if necessary.

2.Measure the float current on each battery cable. If it is fluctuating, measure maximum and minimum.

3.Measure the ac ripple voltage at the battery.

4.Measure and record the float voltage of each cell or monoblock.

5.Perform a load test on each cell or monoblock and measure the internal cell resistance and inter-cell resistance of each cell or monoblock.

6.Ensure that all protective covers are replaced and that the battery is electrically non- hazardous to personnel that could be working in the vicinity

6.4Final Inspection:

1.Verify that the interior and exterior of the system is clean and free from debris.

2.Ensure all wires connected and bolts are properly tightened.

3.Ensure the following the User, Service, and Calibration parameters are set

properly on the controller (default settings are in parenthesis): LVD (Param)

LVD1 Trip (-42.00 V)

LVD1 Reset (-48.00 V) Batt (Set-alm)

Batt Disc Thr (10 A) Batt (Param)

Batt Float (-54.00 V)

Batt Max Rech (10 A) Batt (Comp)

Comp Method (ON).

4.Verify on the status menu that the system is functioning correctly with no alarms.

5.Be sure to leave the site as orderly and neat as possible.
