When to Replace Batteries

intermittently, the batteries may need replacing. Contact your service
representative to order new batteries.
Replacing Batteries

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 batteries, see
“Turning the UPS Off” on page 40.
