Battery Maintenance Determining When to Replace Batteries When the On Battery/Low Battery LED (1) illuminates amber or the Bad Battery LED (2) is flashing red, batteries may need to be replaced within 30 to 60 days. 1 2 Figure 4-1: Indicators for battery replacement To check a battery alarm, initiate a UPS battery self-test to verify that battery replacement is required. If both the On Battery/Low Battery LED and Bad Battery LED remain illuminated, replace the batteries as soon as possible. NOTE: Depending on usage and environmental conditions, the batteries should last three to six years. For more information on initiating a self-test, refer to the section, "Initiating a Self-Test," in Chapter 2. Obtaining New Batteries New batteries may be required within 30 to 60 days when the Bad Battery/Low Battery LED and Bad Battery LED illuminate. Obtain spare batteries for the UPS when this occurs. HP supplies spare battery packs for this UPS. The UPS spare battery kit part number is 240791-001. CAUTION: Because of the short shelf life of the battery, avoid storing a battery spare as a backup. Do not maintain an onsite inventory of spare batteries unless a procedure to keep the stored batteries charged is implemented. 4-2 HP Uninterruptible Power System T700 Models User Guide
