What to do if my Cover MR UPS has mains but no output when power is off?

When the Cover UPS has mains power but no output when the mains are off, begin by inspecting the battery for faults or damage. Also, check the charger and wiring connections to ensure they are secure. The issue could stem from a faulty battery, a charger problem, loose wiring, an open battery breaker, or the UPS remaining in bypass output status after a significant overload.
