Now about the meter in series thing Paul, I'm kind of a tard when it comes to electronics, dumb it down a notch so I know where to put the probes.

Paul beat me to the current measurement idea :-)
What he meant by "in series" was, if your meter can measure currents of the milliamp/microamp range, devise a way to connect one of the battery contacts and its CyberCommander terminal through the meter rather than directly, while leaving all other connections as normal.
The most straightforward way of doing this that I can think of is take a couple of inches of the double-sided Scotch tape and paste a strip of aluminum foil (Renold's Wrap, etc.) almost as wide on each side of the tape. This would form a 1/2" x 2" sandwich of two pieces of foil and the double-sticky tape in between.
Now take out one of the batteries from the CC and put it back in such that one tip of your foil sandwich is jammed between one of the terminals of the battery and the appropriate CC terminal (which, if the battery is inserted normally and the aluminum sandwich strip weren't there, would make contact directly). It does not matter which battery or which terminal - just make sure the two pieces of foil do not become unstuck and touch each other in the process. You can confirm it's fine if the resistance between the two pieces of foil is very high (over a million ohm) or your meter shows a broken circuit. Now you can use any non-metallic or insulated clamp to get the two probes of your meter touch the two respective sides of the aluminum sandwich strip you've made.
If the connection is secure and your meter is switched to the current / milliampere metering mode, you can try turning on the CyberCommander. If the CyberCommander works but your meter is showing 0, try switching to micro-ampere range if you have it.
Please note that I am just a fellow forum participant (albeit with an EE degree) so unless Paul or TS approves please proceed at your own risk.
Also if it is confirmed that the batteries that CC considers drained, are in fact nearly full (a high open-circuit voltage alone is not enough to confirm that this is the case), the culprit must be not the high drain current but an unusually high minimal usable battery voltage requirement of the particular CC unit in question.
Good luck
