They don't have any built in back up protection, even in the event that the battery just runs down. Really?

I was at 17,900' about 90 miles from home in the Colorado Rockies when
my Mountain High system began chirping its alarm. I flew a high speed
final glide home (there was a lot of lift to reduce descent) thinking I
was out of oxygen. On the ground, I found plenty of O2 in my tank so I
swapped the batteries in the electronic box and everything went back to
normal. I had the batteries in the cockpit but didn't think of swapping
until I was on the ground.
