Battery care and storage guidelines
CAUTION: Because of the short shelf life of the batteries, avoid storing a battery spare as a backup. Do
not maintain an inventory of spare batteries on site unless a procedure to keep these batteries charged while
in storage is implemented.
To maintain the batteries:
• Minimize the amount of time the UPS uses battery power by matching the UPS configuration with the
utility voltage. See "Selecting the UPS voltage configuration (on page 22 )."
• 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°C (77°F).
• If storing a UPS for an extended period, recharge the batteries (" Charging the UPS batteries " on
page 27 ) every 6 months, and then update the battery recharge date label.
UPS battery replacement procedure
This component is hot-swappable and can be replaced without powering down the UPS.
1. (optional) To replace the component with the UPS powered down, refer to "Powering down the UPS
(on page 36 )."
CAUTION: When hot-swapping batteries, the UPS is not protected in the event of a utility power failure,
unless an ERM is installed.
2. Remove the UPS front bezel.
