Tried Out Dreamstation On 12V

Post by edatlanta » Wed Apr 11, 2018 5:48 am

I live in an RV full time and will be boondocking week after next so I tried out my Dreamstation on 12v last night. I used the 12v plug from Respironics and it worked like a champ. I have 2 golf cart batteries in series for power and a generator to keep them charged up. I usually have the generator on for an hour in the mornings for coffee and a couple of hours in the evening for TV.

Talladega here I come. I volunteer there for the races so I will be there for 6 nights.

Oh man, party time. Have fun.

Many, many moons ago I worked at the hospital in Talladega....worst punishment in the world was being on call race weekend.
You might as well bring a change of clothes and plan on staying the weekend. I lived in Anniston so it was a bit of a drive every time I got called back.
Man, I hated that damn race back then. :lol:

Now I am a bit green with envy because I secretly would like to be there and part of all the fun.

The golf cart batteries have been the "bang for the buck" winners for me. Two of the smaller size, as in Trojan T105 6V, will provide 225 Amp-hours at 12V, plenty for a cpap even with humidity (which you won't need near Talladega). I use 4 oversized T145's for about 500 amp-hours on my boat, but I'm running a fridge full time, on top of all the smaller devices.

Glad it worked. Did you use the humidifier?

I don't know how it would work for me as my min pressure is 13.5 and I use highest humidity and highest setting for heated hose.

Note that you need to use a Respironics compatible cord interface. If you use another 12-volt DC cord that fits in perfectly, it still would not work.

When we use our trailer without power we depend on two 6 volt golf cart batteries as well. I have found with a ResMed S9 and no humidifier, we can do a long weekend without any AC power. However sometimes we camp longer, and I have added a 70 watt solar panel. It keeps up and we can go on indefinitely with it. But if I was buying again, I would get a 100 Watt panel.

I added two 100 watt panels on my boat - one on either side so that one always gets the full sun, and sometimes both. The result is my boat can be left unattended with the fridge running almost indefinitely. The fridge load is 35 to 50 AH, more than a cpap with full humidity (as long as its not through an inverter!).

Yes, that was with my wife's S9 running off an inverter. I've now joined the CPAP club with an A10 and have bought the 12V to 24V converter to minimize the load. Need to buy the same for my wife's S9 and ditch the inverter. Hoping that the existing setup will do the job, and based on ResMed's battery guide, it should. If not I see Costco has a 100 Watt panel on for $170, and that may be in the cards if it doesn't.

I drive one of the ADA golf carts around the track. I'm not a big race fan, but driving this cart I have go anywhere pass and the cart can go anywhere except the hot pits and I can get right to that. This is people watching at it's best or worst depending on your perspective. I have taken two people to the track ER so far. Both suffering from too much of the night before that thought they were dying.

Mine are T105's. They have been in service with full time RV use since late 2010 and they are still going strong. I make sure they NEVER get low on water and they just keep on keeping on.

My husband loves it. He would love to be there and camp out and get right in the middle of all of it.
Me...not so much...the noise does a real number on my headaches and it's not a good number. When I lived down there it was the last place I ever wanted to go but I don't do well with crowds..drunk or sober. :lol:
I was working at the hospital when that driver got killed there some decades ago.
I saw all I wanted of the race aftermath in the ER.

Now I am content to watch it on TV and I will wave to you wherever you are. Enjoy and have fun.

Mine seem to last 7 years. They get heavy use 6 months of the year, then near total neglect during the winters. Hopefully with the solar panels keeping them well charged during the winter they'll go a few years longer. I try to replace them when they're down to about 80% capacity.

When I got my last set I asked for the automatic watering system but I was told that in a bouncy environment they failed too often. It does seem that I use less water now that the solar panels keep the charge level higher. Or maybe the alternator, which I use infrequently now, overcharges a bit and boils some off.

I bring mine inside in the winter. I've had too many freeze and split. Another trick is if you possibly can, is have them fully charged before you transport. An electrical engineer friend tells me that the plates are more physically stable when they are fully charged. If not charged and subject to vibration material can slide off the plates, go to the bottom of the cell, and cause permanent damage. Not always possible to do, but with solar panels, you have a better chance.

I apologize if I missed it by why use 2 6V batteries when 12V deep cycle battery is readily available? I have a 12VDC/120VAC power pack that I keep at the ready. Have not yet tried it.

The short story is that golf cart batteries have more amp hour capacity and are built different with wider spacing to be truly suitable for deep cycling. The Group 27 automotive and described as deep cycle, often are identical to the automotive version but have shorter warranty periods, to protect the supplier, not you. If you consider life, the golf cart batteries come out ahead. See this article for a bit of a comparison.
