Perhaps it would be possible to include a script to disable battery compatibility checks or set them however the user likes.  Does chdk support the idea of a script executed at startup like a users profile?
You can have a script autostart when the camera powers up.  But you can only have one currently "active" script, so that limits your ability to run other scripts.

Regardless, this would still put CHDK in the position of defeating something Canon has every right to put into their cameras. For the first time ever. 

Very much not a good idea.  Moves CHDK from a possible "fair use" position to something much, much more risky. 

If it goes down this route, I'm completely out of here!

I checked in the non-battery parts of the patch posted earlier, trunk r4745.

I'm not inclined to add any code to specifically defeat the battery check.

Non-Canon Battery  (as found, by H-H, on the 16/June/2016)

Note:- The LP-E17 Battery might also contain a microprocessor. !!!
(for the full Details, see the attached file "Non-Canon Battery.txt")

Obviously, what users do with the existing startup script functionality or their own builds is up to them.

I doubt that CHDK will have time to run the script before battery menu appears.
At this moment menu-disabling code is executed before the moment when camera initializes controllers and starts GUI.
On M3 battery menu appears only one time after battery cover was closed. How it works on your cameras?

Your strings are present in .xml file that I attached on previous page. But we don't know how Canon uses this information...

I own nine different Powershots - six of which use Canon proprietary batteries (i.e. not standard AA cells).  I have one genuine Canon battery for each and many low cost 3rd party batteries as well.   

All the Canon batteries still function properly, although the oldest have somewhat diminished capacity of course.  Of the 3rd party batteries (i have several per camera and many different "brands") more than half have swollen up enough that they don't fit into their camera very well, and about 20% will no longer charge.
 

I can agree this.
Just checked them

Still my old batteries (15 year old) from my S45 have around 30% capacity…

It's interesting that camera is collecting information about batteries usage(G7X too) and maybe sends it to somewhere...

Interesting stuff…
But what is the camera doing with a cheap plastic DC coupler?
As I know these couplers have no electronics inside…

In this case battery icon is not displayed and battery temperature is not measured
But in future I'm expecting new DC couplers with a chip. This corresponds to chosen marketing policy.

Is the handling from DC couplers and non-Canon batteries different?
When yes => how the cam knows, that is a DC coupler?
When no => why it is so difficult to build non-Canon batteries?

But not actually for the M3 or G7x …
