Storing the UPS and Batteries

If you store the UPS for a long period, recharge the battery every 6 months by plugging the UPS into a power outlet. 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.

NOTE: With the user-replaceable battery feature, UPS batteries can be replaced easily without turning the UPS off or disconnecting the load.
