Battery Maintenance

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 25oC (77oF).

•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.

CAUTION: Because of the short shelf life of the battery, avoid storing a battery spare as a backup.

Pre-Failure Battery Warranty

The Pre-Failure Battery Warranty, standard on all UPS units, extends the advantage of a three-year limited warranty by applying it to the battery before it actually fails. Specifically, the Pre-Failure Battery Warranty ensures that when customers receive notification from power management software that the battery may fail, the battery is replaced free of charge under the warranty.

The highest standards in the industry are maintained, as evidenced by the Pre-Failure Battery Warranty. This warranty is beneficial in at least two significant ways:

•Reduced total cost of ownership

•Reduced downtime

A Pre-Failure Battery warning is given 30 days prior to a battery failure. The warning is indicated in one or both of the following ways:

•An LED showing that the battery is low

•Notification from power management software

This warning provides ample time to order a spare battery. To order a spare, go to

The battery warranty coverage is three years for parts. The warranty for the first year of ownership includes parts and labor. If battery spares are not available for a particular UPS model, then the entire UPS, including its battery, is replaced.
