Vehicle car battery as a CPAP power source?

I didn't think that it needed moderation until just today.
Number 1....I don't like bringing politics into things...not needed and to be honest it really turns my stomach.
Number 2....I don't like people being dishonest.
Number 3....I don't see trolling here....I see honest remarks that someone didn't like seeing for some reason or other.

Just because we don't like the truth doesn't mean it is "trolling".

Sigh..


Get back on topic or risk thread lock down...and in case anyone forgot...the topic was batteries.
Everyone knows this is the one and only warning.
Thank you.
