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 o C (77 o F).
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
www.hp.com .
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.
