ResMed 11 Battery Backup

I do not know if this has been discussed here or not, but when switching from a ResMed Auto Sense 10 to 11, special cables must be used. The ResMed 11 DC input uses and odd (to me any way) looking connector that is not compatible with nearly any thing that you may have existing. In my case, I had a Model 10 with a Pilot Lite Battery Backup System. The cables from the new Model 11 power supply to the Pilot and then on to the ResMed 11 must be replaced with new Pilot/ResMed 11 specific cables. One vendor (not on the recommended vendor list) has a kit that includes both cables so the new connections are easy, otherwise you will not be able to use the Pilot Battery System. I image other battery backup plans may also need replacement cables. 

You will need to search for the proper cables. I had trouble finding the necessary cables from any one.

If my memory serves me correctly, look at the AirMini power cable.

I believe that I had read that some where also, but did not want to mention it without knowing for sure. In the Pilot's case, it takes two special cables. One from the new ResMed's power supply and the second cable from the Pilot to the ResMed 11. Regardless, anyone thinking about battery backup for the ResMed 11 needs to be careful.

I wonder why ResMed decided to use such an unusual DC connection.

Generally, can't people use a UPS which should work overnight or a deep cycle 12V battery and a DC to DC converter? Sure it's heavy but a CD battery would last for days.

I called ResMed about this and so far, they have no plans to make a battery backup for the Airsense 11. They have one for the Airsense 10 and it comes with the proper cable so if you kept your Airsense 10, you can get the battery backup for power outages. The two things to keep in mind are: 1) Is the pressure the same or close between the two CPAP machines 2) The battery backup for the Airsense 10 is $300.

We use a Jackery battery and get multiple nights, connecting with the ResMed 12V to adapter. Very easy solution, capable of charging our cellular phones, great for camping trips, etc. Power outages are a way of life for us, here in Tampa. In fact, we're currently under siege at the moment. Our current weather is absolutely nasty and getting worse by the hour.

I understand the struggle, nothing worse than power going off in the night and you waking up feeling like someone is holding their hand over your mouth!

In my case, I put a 1100va UPS unit under my bed. It was a unit that I got from a customer because the batteries were bad. I put new batteries in it at least 10 years ago. No more waking up in a panic! I’m sure you could buy a smaller unit for $50ish dollars at Best Buy and be good to go.
