Neil,

While the battery may be showing 13+ VDC, that does not mean it's
"good".  Most modern alarm panels do a load test of sorts to determine
how long the battery will hold its charge during a power outage.  When
the panel says "Low Battery" it's telling you that the battery has
failed the test and is no longer able to operate the alarm system for
the required minimum time and still operate the siren upon alarm.

As others have said, do replace the battery.  They're not expensive.
The 12-Volt, 7 AmpHour rechargeable gel cell battery retails for
anywhere from $16 to $22, depending on make and vendor.  You don't need
an alarm technbician to replace it.  Just buy one and swap them out.
