Battery Maintenance

Charging Batteries

When connected to utility power, the UPS automatically charges the batteries. No user intervention is required while the UPS is in use. Refer to the section, “Care and Storage of Batteries,” in this chapter for information on keeping the batteries charged while the UPS is in extended storage.

Determining When to Replace Batteries

When the Alarm LED (1) is solid red, and the LCD displays either a Battery Needs Service or Battery Test Failed alarm, you may need to replace the battery module. Depending on usage and environmental conditions, the batteries should last three to six years.

To verify the above alarms, initiate a UPS battery self-test to verify that battery replacement is required. If the Alarm LED (1) is solid red and the alert displays on the LCD status menu, replace the bad battery module as soon as possible.

Refer to the section, “Initiating a Self-Test,” in Chapter 2 for more information on initiating a self-test.
