Battery Maintenance 5-3
When to Replace Batteries
If the red LED flashes, check the LCD display for the type of alarm. If the
alarm reads “Battery Self-test failed,” your batteries should be replaced within
30 to 60 days. The red LED will be accompanied by an audible alarm, if
enabled.
NOTE: Depending on usage and environmental conditions, your batteries will last 3 to 6
years after purchase.
Verify that battery replacement is required by initiating a UPS self-test (press
the Test/Reset Alarm). If the red LED is still flashing after the test, replace the
batteries.
See Chapter 3, “Operation,” for information on initiating a self-test.
Pre-Failure Battery Warranty
The Pre-Failure Battery Warranty, standard on all Compaq Uninterruptible
Power Supply (UPS) models, extends the advantage of a Compaq three-year
limited warranty by applying it to the battery before it actually fails.
Specifically, the Pre-Failure Battery Warranty ensures that when Compaq
Power Management software notifies customers that the battery may fail, the
battery is replaced free of charge under the warranty.
Compaq maintains the highest standards in the industry, as evidenced by the
Compaq Pre-Failure Battery Warranty. The Pre-Failure Battery Warranty is
beneficial in at least two significant waysreduced total cost of ownership
and reduced downtime.
Obtaining New Batteries
Compaq supplies replacement battery packs for all UPS models. Procure
replacement batteries for the UPS when the LCD alarm reads “Battery Low,”
indicating that new batteries will be required in 30 to 60 days.

batteries on-site unless you implement a procedure to keep these batteries charged while
in storage.
