How long will this UPS power my system when the power goes out?

Runtimes of any UPS will vary based on the amount of power required by your connected devices.

Will the UPS automatically switch off from the battery backup when power is restored?

Yes, when adequate power is restored to the UPS and is within the operating voltage range of the UPS, it will revert to passing utility power to connected electronics.

My UPS is on, but my power button is blinking and beeping.

The battery needs to be connected first. Please read the user manual for instructions on connecting the battery.

Can I plug the UPS into an extension cord, or does it have to be plugged into a wall outlet?

To get the best power available, your UPS should be plugged directly into the wall outlet. Plugging your UPS into a surge protector may cause the UPS to go to the battery often when it usually should remain offline.

Is this UPS battery user-replaceable?

Yes, the UPS is compatible with a dedicated user-replaceable battery, and the APC replacement battery cartridge helps restore UPS performance to the original specifications.
