BX1500G shows no bars on battery indicator nor time remaining

[Anonymous user]

The battery went kaput on the unit a while back and I got around to replacing the batteries.

With AC plugged in and batteries in, I get a solid battery with no bars and no time remaining.

Disconnect AC power, I hear it switch to battery as the fan kicks on, and it still has the same battery display with no bars and no time remaining.

I know the battery is good as I have another of the same unit and swapped it out and it works fine.

To do this, follow the below procedure; 

1: Disconnect any attached load.

2: Unplug the UPS from the wall socket.

3: Disconnect the UPS' internal battery.

4: Push and hold the "On" button on the UPS for 5 seconds

5: Reconnect internal battery.

6: Plug UPS in to known good power source.

7: Turn UPS on.
