CPAP machine and batteries

[djg]

I've just been informed I have to use a CPAP machine and was wondering if anyone out there uses this with just batteries, currently have 2 AGM 12 volt batteries group 31 I think about 240 amp hrs and was wondering if that is enough power to run a home unit. We usually drive during the day and do not camp for much time mostly sightseeing tc'ers, love the driving part and love scenery

i feel better as on below marketplace for CPAP batteries as you can get good contemplative price here as per compare with others market.

I have used nothing but tap water in my cpap humidifier for 5 years with no problems. I use the highest setting, so it goes through a full tank of water in 10 hours. If any minerals start to accumulate, it is a 20 second process to wipe it off. Distilled water is an unnecessary inconvenience.

Quoting my own post here and revising my opinion. I got some nasty water down in Florida in February that left a nasty, scummy residue in the CPAP tank. So now I can see why people use distilled water, if they have water like that. I still use tap water water without issue, once I drained out that water and got a refill. But I now carry a jug of distilled just in case.

Y'all realize this thread is 2 1/2 years old don't you?

My wife has used a CPAP for years including all the years we travelled as part or full time RVers. If you have a CPAP that only operates on 120v, you can use an inverter. Get a small unit because inverters waste power as heat. Most get so hot they have a built in fan. All wasted energy. If you camp a lot or are getting a new unit be sure to get one that operates on 12 volts without an inverter.

Most CPAPs will use about 25 AH of power so the drain is manageable. The problem occurs for the use of a humidifer or one of the new heated hoses. Those devices can use several times the amount of power. It can be a major issue in cold weather. To get by my wife sets her unit on a hot water bottle and wraps it with insulation.

There was a question about the validity of CPAPs. This is not a good place for a detailed discussion but I can make a quick summary. First many people really do benefit and without a CPAP have all sorts of issues in addition to not sleeping well. Unfortunately, much of the "science" and testing is questionable. It is no accident that Respironics makes most of the CPAPs and also makes the testing equipment including the software that analyzes the results. I was among the high percentage of those tested who was told I needed a CPAP. I insisted on a retest at a different facility and got a completely negative result.

In the case of CPAP https://cleanhomeguide.com/lumin-cpap-cleaner-reviews/, in order not to suffer from still high, but now unnecessary pressure, you will have to “play” well with the setpoint but not to lower it more than necessary (carefully analyzing the results using a program like SleepyHead), or even apply for polysomnography again. If you have an APAP, then you don’t need to do anything at all. Over time, the upper limit of the pressure range will get too high, which does not lead to anything bad, the pressure will just reach, for example, not 14-15, but only 11-12, although it is still allowed up to 15.

You don't mind hearing that thing whiring away?

Some whirl and some do not. Either way, it is quieter than my CPAP.

Wow.... thanks for the comments everyone. Now I can sleep at night not having to worry about it...LOL In the winter, (I live in central Iowa)... with my humidity set at 5, I sometime wake up at night with dry mouth. Will just have to be vigilant and keep a watchful eye on the battery at all times. Going to switch over now to a lot of questions on sway bars, etc. for the new trailer and will post in another area of the forum.

My Philips Restonic (sp) is a 12 volt unit, which I think most are. So all I needed was the 12 volt cord. In the TT I installed a 12 volt cigarette lighter plug in beside the bed. I'm yet to do that in the TC, it's on The List. Right now I use the Optima 24 AGM from my trolling motor and a clip-on cord with a cigarette lighter plug end. Optimas don't spill. I'll be using that cord in OZ in couple of weeks, too. At the clinic they sell 12 volt batteries for the machines. They look like a 24 AGM battery. They claim 24 hours use from one. I hope my experiences help with your sister's travelling.

I am expecting my wife's sister for a visit and the two of them are planning on a road trip in the TC. She (sister) uses a CPAP and will need to be accommodated. I have a 300W Pure Sine Wave inverter that I use for astronomy and it will plug into the lighter socket in the cabover. Is this okay? Or is it too much inverter for the job and it will kill the batteries? (two group 27's, lead acid)

Should I have started a new thread? Sorry if I am sidetracking this one.

I camped in Namibia with mine. It's a 12V that converts the 120volt.It was simple to hook up to the bakkie battery. We had a roof tent. As I've used it I'm needing less water, I'm using #2 setting now. When I was hunting I camped in a wall tent and used a # 24 deep cycle, supposedly it was good for three nights. Off to OZ and will be hooking up to the 'ute's battery, again a roof tent.

There is what you need. you can also get an extension with clips for going right to a battery. You'll use something like 25AH per night if you skip the humidifier. What I find is that you get enough condensation in the hose to make up for the humidifier, or maybe it's just that the air when camping is not as dry or warm as at home.
