Battery Maintenance
Conducting a Battery Commissioning Test
When replacing battery modules, Compaq recommends running a battery commissioning test.
This test will set a base line so that the UPS accurately displays battery run-time. See the
section, "Set Hardware Configuration," in Chapter 3 for instructions on enabling the battery
commissioning test.
NOTE: The battery commissioning test runs in the background. Once enabled, the test can take up to
three days to run.
Disposing of Used Batteries
The spare battery kit includes the instructions and packaging required to return used batteries
to the appropriate location for disposal.
Care and Storage of Batteries
To maximize the life of batteries:
•
Minimize the amount of time the UPS uses battery power by matching the UPS
configuration with utility voltage. Refer to the section, "Matching the Utility Voltage," in
Chapter 3 for more information.
•
Keep the area around the UPS clean and dust-free. If the environment is very dusty, clean
the outside of the UPS regularly with a vacuum cleaner.
•
Maintain the ambient temperature at 25
•
If storing a UPS for an extended period, recharge the batteries every six months:
— Connect the UPS to utility power.
— Allow the UPS to remain in Standby mode.
— Allow the UPS to charge the batteries for 24 hours.
— Update the Battery Recharge Date label.

Batteries, battery modules, and accumulators should not be disposed of
together with the general household waste. In order to forward them to
recycling or proper disposal, use the public collection system or return them
to Compaq, your authorized Compaq Partners, or their agents.
CAUTION: Because of the battery's short shelf life, avoid storing a battery spare as a
backup.
