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
3 hours. However, to fully charge, HP recommends that the batteries charge for 6 to 24
hours after long-term storage.
Check the battery recharge date on the shipping carton label. If the date has passed
and the battery was never recharged, do not use the UPS. Contact your service
representative.
