Hi,

Try resetting the UPS

 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.

If it still will not charge after the reset that would indicated the charging circuitry took a hit during the power outage and the UPS should be replaced.

I have the opposite need. I'd like to disable the battery charger, because Im using lithium batteries and have an external charger, SUA1500.
