6.3 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 batteries charge to
90% capacity in approximately 4 hours. However, it is recommended
that the batteries charge for 48 hours after long-term storage.
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 status summary screen displays the UPS fault icon with the
"Service Battery" alarm and the audible alarm sounds continuously, the
batteries may need replacing. Contact your service representative to
order new batteries.
