Exactly, unless there is some sort of on-board switch, parasitic draw will kill the best of Lithium batteries today, much less 12 years ago.
I can do the math, but a good starting place for everyone is Watt-hours and Radio receiver current draw in standby.
EDIT: Maths times!!!!!
Smallest commercial Transmitter/Receiver with specifications I could find.

Assuming hours of operation = (24 hours/day) x (365 days) x (12 years) = 105120 hours
Assuming 12 Volt battery
Assuming 5mA (0.005 Amps) of "quiet" radio operation
(105120 hours) x (0.005 Amp) = (525.6 Amp-hours) x (12VDC) = 6307.6 Watt-hours
The link below are traditional hobby Lithium-Polymer batteries. 3S means 3 LiPo batteries in series. (~3.7VDC/battery) x 3 = nominal 11.1VDC. At 5000mAh (5Amp-hours) per pack, we would need about 100 packs.

And mind you, this is without any reserve battery power left in batteries after 12 years. We still need to have enough juice to have the receiver be functional and run the motor(s) to move/shred the painting
Overall, the Maths says bulllllllllllsheeeeeeeet. Again, there is a switch installed somewhere or the frame was swapped out.
