------  New battery  static voltage  no load  12.75 VDC,  under load from
panel  12.25 VDC
------  Original battery  static voltage  no load  12.00 VDC, under load
from panel   11.75 VDC
-------    (( panel should not give "Low Battery" warning till voltage
reaches 10.75 VDC  least wise other panels only report at that voltage..))

--------  It's possible,  but  a completely different panel (2T)  gave the
same report..

-------  You'd think that  But  it's happening...

------  Doubtful locked in memory,  original panel was defaulted and then
reprogramed and again a totally different panel was  used with the same L.B.
report...
------  As for programing out the low battery feature,  I'm not sure that
can be done with  FBII panels..  You can disable the sounder on the keypad,
and disable the communication signal.  But I don't think the test itself can
be stopped..

-------  We run the panel into and out of program mode to recycle the
features..

-------   All in all   I think the keypad is the cause  but  I can not
figure out how it is causing the observed problem...
