What to do if my DirectUPS UPS shows Battery mode even when mains are normal?
If the LCD displays Battery mode when the mains are normal, it could be due to a broken circuit breaker. Try resetting the circuit breaker. Alternatively, the power cord might be loose; ensure it is properly reconnected.
Why is the DirectUPS UPS backup time so short during a power failure?
Shortened backup time during a power failure can occur due to several reasons: * The UPS might be overloaded. Try removing some noncritical load. * The battery voltage may be too low.
