Air Mini or Micro 501 with batteries

I've been using a CPAP for over two decades now. I'm increasingly camping in areas with no electricity and even backpacking for several night trips. Been looking at these two options, but can't find info on how much their portable batteries weigh and how long they last at a setting of 10-12.
Anyone use either of these with the portable batteries that could tell me how much the batteries weigh and how long they last. Thanks in advance.
