Something is drawing current. Somebody needs to explain what it might be. My only thought is crossed -/+ which would consume energy as heat. Are the wires warm? I know that's a dumb question. Do any indicator LEDs or anything stay lit on the board?
Might not be worth tearing out the mpu board to find out. Maybe a timer or chip that doesn't stop when powered down.

I would ask on RGP.
I'll check if the wires are warm. Nothing stays lit on the board and I'll post on RGP too.
If the batteries last 3 weeks, you will surely not detect any heat, as the decay rate is too 'slow' to generate noticeable heat. It would be different if the batteries lasted 3 minutes!
It *could* be a bad 5101 CMOS RAM chip, or one of the mod.

Yes, they will still drain down, the wall voltage has nothing to do with the backup batteries. You need to check D17 first and if it is okay, then look at the 5101.
