If you have an extra inch or two above your batteries then the hands down way to go is the Costco or Sams Club dual 6 volt batteries. They are basically the same price as 12v automotive batteries and have a lot more amps on reserve for when the generator is off.
Actually 6V golf cart batteries are LESS than standard car batteries. About $90 with trade-in.
I am not sure what medical device you are using, but if you are running a CPAP, you can but a power adapter so it can run directly off of 12VDC. Much more efficient than running off of an inverter and you will be able to sleep all night on a full charge of these batteries
WITHOUT the generator.
