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, it is recommended
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 expired and the batteries were never recharged, do not use the
UPS. Contact your service representative.
Replacing Batteries
NOTE
DO NOT DISCONNECT the batteries while the UPS is in Battery mode.
With the hot‐swappable battery feature, UPS batteries can be replaced
easily without turning the UPS off or disconnecting the load.
If you prefer to remove input power to change the battery, see “Turning
the UPS Off” on page 36.
Consider all warnings, cautions, and notes before replacing batteries.
