need recommendation on Battery pack for CPAP

[B_4]

383:

I am an assistant scoutmaster with my son's troop. I have the following rig for camping:

CPAP - Respironics DS250 - Compliance only but it has CFEX I purchased for $250
https://www.cpap.com/productSearch.php?query=ds250


Battery Pack - Respironics 1028869
https://www.cpap.com/productpage/respir ... e-kit.html


I can get about 3 full nights on the battery CPAP combo. The battery pack weighs about 12.5 lbs. I bought them both from secondwind cpap for a total of about $500 delivered. I like having a second CPAP so I am not taking my primary CPAP into the woods and weather.

Good luck!

There is no substitute for having a spare mask/machine for travel, camping, or whatever. Loss or damage aside, you can also reduce the chances of forgetting or leaving something behind (coming or going) plus when you get home you may be tired and just want to lay down (w/o unpacking).

Forgetting to dump the humidifier water before packing is the biggest cause for a ruined cpap. IF you forget just do NOT apply power to the machine until it is completely dry inside and it may take 2 or 3 days.

The question that I really don't know is how long will the Lead Acid battery last compared to the Lithium Ion since I will be using it once a month and can the batteries be bought and replaced separately through a battery shop as opposed to buying a whole new setup.

If not abused, the lead acid battery pack will probably last longer than the lithium ion. The lead acid pack will also tend to die slowly by slowly getting shorter run times giving you some warning before it becomes useless. The lithium ion pack will probably suddenly not work at all at some point in the future when you get ready to use it.

We have a company by me that specializes in making battery packs and I wonder if they could put something together that would work that would be more economical to maintain such as replacing batteries going forward.

That's probably OK for lead acid or NiCd/NiMH battery packs. I'd be afraid of getting a custom made lithium battery pack. It's too easy to get a fire or explosion hazard with jury rigged lithium battery packs and chargers.

I went ahead and purchased the lighter Lithium Ion battery from CPAPCharge dot com The guy there named Matt was real helpful throughout the process and they shipped the unit quickly (less expensive than the Lead Acid Respironics battery pack and a lot ligher). I used it this past weekend camping and it worked like a champ. It ran the machine solid for 2 nights and I think it might have been able to handle a 3rd night since it only took about 2 hrs to fully recharge. It comes inside a small camera case that fit in my tent cot very nicely and has room for other items (I will most likely get a 2nd spare battery for in the future). I couldn't have been more pleased with the outcome so far and only time will tell for the long run. I will be using it on a 7 day campout at the end of June (they have a charging station at the camp) so we'll see how well that works out. If I can get 2 nights followed up by a 2 to 3 hour charge and be good for another 2 nights, then I think this unit will work fine.

I would recommend this to others......so far.

I tried to include a link to what I purchased but if you go the CPAPCharge website you will find a system for you unit.

This is exactly what *I* have!

I am doing an experiment this week because of a (short) power outage we had Monday. At about 9:30 am (my work schedule is currently noon to 9:00 PM or later), my power went out. I'd been in bed about 3 1/2 hours. It was out just long enough to wake me up and (naturally) for my clock to start blinking.

I've had this DieHard unit plugged in for about 6 months - just in case. So I brought it into the bedroom, plugged the machine and clock into it...and left it that way. I shouldn't get awakened in the middle of my sleep cycle.

But because it's constantly in use, it never goes back to a 100% fully recharged state. So what I'm watching is whether that number will dwindle (too much drain) or stay constant (drain vs. recharge is equal). If it's the second, I think I'm just going to leave this plugged in the way it is.
