Below is the video about the relay fault found in AVR UPS.

Thanks to Allen S for recommending this video. By the way one common symptom of AVR UPS after replacement of batteries and the battery LED level still low then you need to reprogram the EEprom IC.

    Very nice; I'd be tempted to only replace the bad relay and any of the same model and manufacturer.
