Battery Maintenance Determining When to Replace Batteries When the LED flashes red and the LCD displays a Battery Test Failed alarm, you may need to replace the batteries. Depending on usage and environmental conditions, the batteries should last three to six years. Verify that battery replacement is required by initiating a UPS self-test. If the LED is still flashing and the alert displays on the LCD status menu, replace the batteries module as soon as possible. For more information on initiating a self-test, refer to the section, "Initiating a Self-Test," in Chapter 2 Obtaining New Batteries HP supplies spare battery packs for UPS R6000 models. The UPS spare battery kit part number is 401863-001. CAUTION: Because of the battery's short shelf life, avoid storing a battery spare as a backup. It is recommended that an inventory of spare batteries not be maintained onsite unless a procedure to keep these batteries charged while in storage is implemented. Replacing the Batteries The UPS is provided with an internal lithium battery and a sealed lead-acid battery module. There is a danger of explosion and risk of personal injury if the batteries are incorrectly replaced or mistreated. Only replace batteries with the spare designated for the UPS. For more information about battery replacement or proper disposal, contact your HP authorized reseller or HP authorized service provider. WARNING: To reduce the risk of personal injury, do not attempt to replace batteries unless all battery circuit breakers (UPS and any connected ERMs) are in the off position. There is a 400 Vdc across the batteries. 4-2 HP Uninterruptible Power System R6000 Models User Guide
