Bad news...you're screwed.  First of all, the lithium battery was dead.
That means the panel has lost its program, and you will have to send it
back to the factory for reprogramming.  Even if you had a 5200 programmer,
you'd still be screwed.  The panel contains a "datalock" code, which
prevents one Radionics dealer from programming another dealer's panel, and
now that your panel has a dead lithium battery, no one except the factory
can reprogram your panel.  (Maybe Jim Rojas knows how to fix this, but
ordinary Radionics/Bosch dealers do not.)  A 5200 programmer will show a
datalock violation, and RAM IV software won't be able to connect, either.

I'm a longtime Radionics/Bosch dealer, so I know what I'm talking about.
I've had panels I purchased lose their memory due to that damn lithium
battery, and had to send them back to the factory for repair.  I would
cheerfully strangle the life out of the engineer that designed these
goddamn things.

Rule 1:  do not ever buy a used Radionics/Bosch panel unless you are sure
the seller has restored the panel to factory defaults, and that you have a
5200 programmer or RAM IV software to program it with
