[CPAP] Z1 Auto Question
Hello folks, new to this forum but not to cpap machines. I've have been using them since 2004. I do have a question regarding the Z1 Auto and external batteries.

I enjoy going camping and just recently bought the Z1 Auto for its compactness.

My BPS C-100 battery does not work that well with this unit in the sense that the Z1 is a 14.4 volt machine and the C-100 is 12 volt battery. The Z1 works for a few hours on this battery then shuts off, probably to due to a low voltage protection circuit built into the Z1. The battery works great on my DeVilbiss IntelliPAP machine.

I found a site the sells Lithium Ion batteries that I think would be great for the Z1.

However here comes the $64,000 question. The batteries that I an interested in are 14.8 volts and the Z1 is a 14.4 volt machine. Will the additional 4 tenths of a volt kill the Z1?????

Yes, it is likely the low voltage shut down is at fault here.

As for the battery voltage, I wouldn't think it would hurt anything but you best bet is to ask HDM.
