Storing the UPS and Batteries
If you store the UPS for a long period, recharge the battery every
6 months by connecting the UPS to utility power. The internal batteries
charge to 90% capacity in less than 3 hours. However, Eaton
recommends that the batteries charge for 48 hours after long-term
storage. If optional EBMs are installed, see the recharge times listed in
Table 25 on page 90.
Check the battery recharge date on the shipping carton label. If the date
has passed and the batteries were never recharged, do not use the UPS.
Contact your service representative.
When to Replace Batteries
When the indicator illuminates, the audible alarm beeps, and the
“Battery Needs Service” alarm displays, the batteries may need
replacing. Contact your service representative to order new batteries.
Replacing Batteries
NOTE DO NOT DISCONNECT the batteries while the UPS is in Battery mode.
Batteries can be replaced easily without turning the UPS off or
disconnecting the load.
If you prefer to remove input power to change the batteries, see “UPS
Shutdown” on page 47.
Consider all warnings, cautions, and notes before replacing batteries.
