Would 2 12V batteries in series avoid need for Resmed''s (A10) converter

Would 2 12V batteries in series avoid need for Resmed''s (A10) converter
Am guessing it isn't that simple and don't  remember reading an answer among the numerous posts about backup power.
I have no particular qualifications or expertise with respect to the apnea/cpap/sleep related content of my posts beyond my own user experiences and what I've learned from others on this site. Each of us bears the burden of evaluating the validity and applicability of what we read here before acting on it.  

Of my 3 once-needed, helpful, and adjunctive devices I have listed, only the accelerometer remains operative (but now idle). My second CMS50I died, too, of old age and the so-so Dreem 2 needs head-positioning band repair--if, indeed, Dreem even supports use of it now.

RE: Would 2 12V batteries in series avoid need for Resmed''s (A10) converter
You need the Resmed Airsense 10 DC power converter to run your machine from a battery, and the battery output needs to be 12 volt. The converter upconverts the power to24 volt, but more importantly, it includes a proprietary signal on the center pin. The machine will not run without the OEM connector. So nice idea, but it's been covered, and unless you're a really geeky electrical engineer that wants to hack a cable, it isn't worth it.
