DSC replacement battery problems

I have the DSC power series 832 system. We just had the cellular communicator upgraded to LTE, and the tech replaced the battery at the same time (even though it was fine).

Ever since, we've had a consistent low battery alert. The tech came back, spent a few hours, and could not get it fixed

He replaced it with the MK ES7-12-SA-X.

Is it possible the new battery isn't strong enough or isn't compatible with the older system? We are only powering 8 zones, and, 2 keypads and the cell unit.

That is a 7ah 12v lead acid battery and is the exact battery required for the panel.
It's possible but not likely a brand new battery has a problem.

Do you have a meter ?
That eliminates a lot of guessing.
Check the current voltage on the battery. Should be better than 13vDC connected.
Check the AC voltage on terminals 1 and 2. Should be around 16.5vAC.

Thanks...the tech checked all the voltages and also replaced the battery. He even added two smaller batteries to run devices separately, and we still have the low battery alert.

He said the panel is failing, and it is just a coincidence this happened when he replaced the cell unit and the battery. Feels odd to me, and if I hadn't of replaced the battery, I wonder if this would be happening.

Can you try to power cycle the panel? Also check if panel is still alive after disconnecting AC and running just on battery.
Remove AC wire, then disconnect battery. Reconnect the battery and then AC, system will reboot and you'll need to set time/date.

It’s not as coincidental as it may appear to be. Was the charging circuit output checked?
When the charging voltage with the battery disconnected is less than 12.8,12.7 vdc then you can presume the panel is on its way out and can go anytime.

I’m assuming the tech has power cycled as described above.
