Table 2-9: Battery Discharge Test
Step Action
1 Turn the battery test switch on the Meter Alarm Panel, ON (see Figure 2-3). The rectifier output
voltage and current should decrease by approximately 10% as the batteries assume the load. Alarms
for the Meter Alarm Panel may occur.
2 Measure the individual battery string current using the DC current probe. The battery discharge
current in each string should be approximately the same (within +
5 A).
3 Turn Battery Test Switch OFF.
Failure to turn OFF the Battery Test Switch before leaving
the site, will result in low battery capacity and reduce
battery life.
CAUTION
