Is it possible to use a normal 12 volt rechargeable battery with a CPAP? I have the cord, but, in addition to that question, do not know how to attach the cord to a normal 12 volt battery. Can anyone help?

This is a concern for a lot of people. I did a search and found this post that has a lot of info on this topic.

Good luck,
Rob

Use this http://www.batteryminders.com/batterych ... 16134.html and this http://www.atbatt.com/product/22345.asp. It will last a week if you have a really big storm. Just connect your 12v cpap to it. Lasts years. Or you can go to Wally World and buy a cheaper deep cycle battery $56 and works fine also. The sealed battery works in any position and wont spill.

A 75AH battery will certainly last several days (without powering a humidifier), but only a user on a quite low titration setting would get a usable week out of one.

Cheers,
