Hi Mark,
Sorry I'm not answering your letter directly. It's a long story. I'm
using a Puritan-Bennett 2801. I just got new batteries so I can stay on
battery power for over 30 hrs. I wired two deep cycle marine batteries
together in parallel to get that length of time. I wonder if anyone
else is having this problem. I have two PB 2801's and ran one on
batteries for 34 hrs. I switched to the other one and it only lasted 5
or 6 hrs. Does anyone else have a problem like this?
Eric
