My alarm panel generated a low battery alert and chime, so I replaced the backup battery that connected to the CPU. After 24 hours the battery is fully charged and test at a healthy 13V. The problem is that my panel is still generating a CPU low battery error.
I tested the leads where they connect to the system board and the voltage there is consistent at 13V. I also tested my old battery and it's still outputting 11V.
I'm not sure what to do next in terms of troubleshooting or clearing the error. Does anyone have any ideas?
