Ensure that you unplug the battery backup from its own power supply so that you get an accurate reading. I believe that you will get a false reading if it’s plugged into power, even if the battery has significantly degraded. A good way to test this is to cut power to your system on a regular schedule (monthly, in my case) to verify that all equipment still functions as expected during a power outage.
