ONT Backup Battery Replacement

[mkoslosk]

I'm attempting to replace my ONT battery to make the beeping stop.  I attempted to do it both here and through my set, but in both cases I get a message that says "this service is currently not working.  Try again later."  It's now been 10 days.  I give up.  My current battery model # is PX12072.  However, when I search this site it apparently does not exist.  The only one I can find is a GT-12080-HG (and you have to zoom in on the photo to see the model number, as no technical specs are provided).  Is this the appropriate replacement for my unit?

The GT12080-HG is the original battery.  The PX12072 is a substitute.  Either will work, though the GT12080-HG has a slightly higher Ah. (8Ah vs 7Ah)   The main difference is cost.

Thank you and Kudos to all of you that has helped me with this subject.  Was ready to tear out my hair.
