BiPap rechargable battery options

My husband has been using a BiPAP since January and it’s definitely doing its job. We are RV’ers and Boaters. RVing is no problem as we stay at parks with power. Boating – we stay at marinas with power but also anchor out for several days. Plus we know we need a battery pack for house power outages.

My husband uses a Responics BiPap Pro Bi-flex (660P) with a humidifier. His two pressures are 10 and 14. I’m told that the Respironics Battery Kit for PR System One 60 Series Machine is the best for him. The other option, C-100 will run down too quickly. And of course, there is the marine battery but would like to avoid that unless it’s the only option.

There is no DC plug close to the bed so he’ll have to use the battery. To recharge the battery we have one DC plug on the bridge of the boat. We also run the generator twice a day (for one hour) to top off our boat batteries. So we can recharge using AC for that amount of time.

So I’m asking for help on what recommendations you might have for while we’re boating and if there are any other options out there. Most important are the recharge times which I know depends on how long he sleeps, leakage, etc. I was told 10 hours on battery but did not get any info on how long it takes to recharge using AC/110 which we have when the generator is on.

I was told the BiPap machine draws 1.15 amps and the humidifier 2.1.
Thanks,

Forum member CapnLoki spends a lot of time on his boat and I imagine he will stop by and try to answer your questions but in the meantime you can go here

and then click on the "members posts" link and read some of what he has offered to others in the past about battery usage.

Since you're on a boat, 12 volt DC power is pretty easy. The BiPAP 660 won't use that much power as long as you go direct DC and don't run the heated humidifier (passover only). I would just get a 12 volt outlet installed in the boat where you sleep and plug this in: https://www.cpap.com/productpage/respir ... -cord.html

Note that cord says no 60 series machines, but the 50 series and 60 series are identical except for the heated tube. You can't run a heated tube due to the higher amp requirement that might draw down your battery. The BiPAP alone won't be a problem on a deep cycle marine battery.

The 50 series machine and the 60 series machine have different sized pins...where you plug into the blower in the back..that little hole and pin.
I had that power cord you linked to and used it with my 50 series machine but when I got my 60 series machine it wouldn't fit. I had to get the one that is specific for the 60 series machine.

The one you linked to will NOT work on a 60 series machine..
instead this one is needed.

Ah, thanks. I thought they were the same...now I know. So this one http://www.thecpapshop.com/respironics- ... gQodnlQAuw

As Pugsie says, I spend a number of nights on board with my CPAP each summer, all on moorings. I don't use the humidifier on board and my basic pump load is 4 Amp-hours a night. This is only 10% of my refrigerator load (never mind the TV, computers, lights, etc) so it really doesn't add much to my power needs.

I'm curious where you heard your pump load was 1.15 - its quite hard to measure and I'd like to collect these numbers. This is 9.2 Amp-hours per night, and your humidifier is 16.8. If you need the humidifier, 26 Amp-hours may be a substantial load on your house bank. Since you will have this issue every time you spend a night on the boat, you should consider this a boat issue, not a CPAP issue, and increase the boat's house bank if appropriate. The backup backup battery I recommend below could certainly be used, but it ends up being more compicated than simply adding a second (or third) battery to the house bank. If you're running a genset twice a day, you may be limited more by battery capacity than generator power. Frankly, I have much more experience with battery power for boats (25+ years) then CPAPs, so if you'd like help with this, PM me with the details of your boat's system and usage.

As for the DC outlets, its easy to add one or more outlets around the boat - at last count my boat has 9 down below, plus one on deck. At the very least, you can get an extension cord pretty cheap.

As for a home backup, I've been recommending this system (last post in thread):

For some background on power usage:

The 35 Amp-hours of this system should be enough for one night with the humidifier. If you expect longer outages, you'll need a larger battery (or another 35AH) or plan to go without humidity.
