SAT battery

[John Ross]

I wouldn't risk removing the disk, unless you parallel connect another 
battery with it. It IS your program hold on voltage.
When it is time to replace the disk, it might be advisable to send it back 
to Inventronics for a service.
The do any updates, and also replace the capacitor. I believe it only costs 
$125, plus the battery cost.
The operation of the voltage system, as I understand it, is. When you turn 
it on, the charged battery charges the capacitor, which keeps the program. 
If the capacitor goes flat, then the disk keeps the program.
That is why, if you are not using it, you should turn it on once a week, to 
keep the capacitor charged.
If the disk goes flat, then you have lost the memory and it has to go back 
to be reprogrammed.
The rechargeable battery just runs the program, as you use it.
The beauty of the SATlll is that it has a flash memory, and doesn't lose 
it's program.
