Which battery?

Post by Kiralynx » Mon Apr 04, 2011 8:22 pm

OK, so I have the connector for my Bipap ASV to run off battery, from CPAP.COM.

But I still don't know, other than a generic "100 AH" battery, what kind of battery I need to get through a night with my ASV on EPAP = 6, MinIPAP=10, and MaxIPAP=14.

Last Tuesday night/Wednesday morning, the power went out abruptly. Just my block. Everyone else in the neighborhood had power. We didn't. Not until 10p Wednesday.

The power just flickered again. I can't take no sleep, not when the store's closing, and my job ends at 1P on April 12.

I have GOT to have a battery. But I don't flaming know what to buy!!

Hi,

From my experience, a 55AH Deep Discharge (marine) battery will keep my M-series BiPAP Auto w BiFlex and the Integrated Heated Humidifier (at a setting of 3) running for two days of camping (at a pressure range of 9-15cm H2O.)

Cheers

I'm sorry. I'm too tired and too stupid to be able to compare your machine to mine.

I am NOT an electrician or electronics specialist. I just want something that WORKS. Simple. Easy. No soddering or finding this arcane bit of whatever and connecting it to that arcane bit of something.

How long do you want this battery to run your bipap? The larger the battery the longer it will operate your unit' .

Cheap way: Go to wally World and purchase a Marine deep cycle battery.55 amp ($55) or 105 amp ($75 ).and battery box($10). They make 1 with the auto style connector built in ($19). Small battery maintainer such as a Batteryminder 1.3 amp available on line for $50. Connect unit to battery permenently. Don't fall for cheaper chargers they will roast your battery.
I keep mine on a very small furniture dolly I bought from Northern tool on line. $10. Whatever connector you need for your unit. May be a "M" style plug. Radio shack or cpap.com. Take your unit to RS to show them. Total cost this way is less than $150. The battery will last several years with the batteryminder brand charger. Much less with others.


More expensive way is to use a sealed battery. Works in any position . Specialty battery store, power wheelchair store(expensive) or solar supply on line. They last longer and don't spill.

Even more expensive is the cpap batterys sold online.

Good luck

Hi,

A 55 AH Marine Deep Discharge battery should keep you going for at least a good night's sleep.

Do you have an automotive type battery charger to recharge the battery after you use it? You should recharge the battery (if you use it or not) at least monthly.

Cheers

Battery capacity varies with the discharge load that is put on it.

A 100 Ah capacity battery has a "reserve capacity" of about 240. This means that under a 25 amp load, the battery will last for 240 minutes.

The chart showing how this battery performs demonstrates this.

http://www.odysseybatteries.com/battery/pc2250.htm

As you can see, if you put a 671.6 amp load on that battery, it will only last 2 minutes, however, if you drop the load down to 11.4 amps it will last 10 hours.

Here is one from OReilly auto parts that has a similar specification.

http://www.oreillyauto.com/site/c/detai ... &ppt=C0327

Notice the size of it. It is a little bigger and heavier than 2 car batteries.

Another option is to parallel 2 car batteries like this.

http://www.oreillyauto.com/site/c/detai ... &ppt=C0327

Are you sure you require 100 amp hours of capacity?

Kira, sorry you're having power issues.

As you may remember, I bought a very portable battery from BatteryGeek (their C-222, which weighs less than 5 lbs. but no longer appears on their website). They have lots of xPAP batteries listed, though: http://www.batterygeek.net/v/vspfiles/C ... _Packs.asp. I would suggest calling them to find out which of the batteries will power your ASV for the amount of time you're hoping to get out of a full charge.

My battery was more than adequate to run my former machine (I got over 27 hours out of a full charge with the M-Series), but we both know that the ASV uses a lot more power than any typical xPAP. The only additional piece of equipment I had to purchase in order to use the battery with the ASV was an inverter. My pressure range is higher than yours, and I get about 6 hours out of a full charge - enough to get me through an emergency.

FYI, these portable batteries are more expensive than the larger ones. I like that mine is so small, as it can (and does) sit on the nightstand next to the machine for those middle-of-the-night outages. Not a big deal to hook it up and get back to sleep.

Hope that helps. (And if it's any comfort, none of this technical stuff makes any sense to me, either. )
Veni, vidi, Velcro. I came, I saw, I stuck around.

Dx 11/07: AHI 107, central apnea, Cheyne Stokes respiration, moderate-severe O2 desats. (Simple OSA would be too easy. ;))

PR S1 ASV 950, DreamWear mask, F&P 150 humidifier, O2 @ 2L.

You will need a BatteryGeek CPAP-250 li-ion battery to suceesfully power your BiPAP Auto SV (sans humidifier) for 8 continuus hours. You will alo need the Respironics proprietary DC Cable.

I'm using this battery now with my Auto SV, in Vietnam.

I have the Respironics Battery pack from cpap.com. I have had it for several years and have used it seveal times. At my pressure of 12 cm it will last for 3 nights - without heated humidifier.
There is an extra cable so I would call cpap.com if you are interested in this one to be sure you get everything you need and to make sure it will work with your machine. It is a bit heavy but I can lift it even with arthritis in my shoulders. Not very good for travel.

I know little to nothing about batteries and that's why I bought this one.

See... this is all completely confusing. All I know is that Respironics told me I needed a 100 AH battery to run the Bipap ASV.

I don't know what it means -- and frankly, I don't CARE. My area of expertise is not electricity.

There's one thing I do know, and that's that a Wally World Battery that is too heavy for me to pick up will be d@mn dangerous to my two dachshunds, and the beagle, who chews on everything. I have to be able to PUT IT somewhere safe. But I also have to be able to get to it easily and safely in the event of a power outage.

I have nothing except this https://www.cpap.com/productpage/DC-Pow ... Bipap.html, which is what both Respironics and CPAP.COM told me was needed for connecting to DC power.

I would probably pick a night -- possibly the first of each month, where I would sleep with the battery power for a night so as to keep it ready.

Actually, I'm not sure of anything you wrote. It might be helpful to someone else, but it makes no sense to me.

No, I'm not SURE that I need 100 AH... but that's what Respironics said I needed, since I may need it to run for 2-3 nights in the event of power outage due to hurricane.

BB,

Yes, thanks -- I did talk to someone named Sean today. He seemed to think their 250 model would work for me, especially since I have this gadget https://www.cpap.com/productpage/DC-Pow ... Bipap.html which means I don't have the double power loss of going from DC to AC to DC with the inverter. At my pressures, he seemed to think I might get two nights out of the 250.

I admit that the idea of a compact unit which can sit, out of reach of fur kids, has an attraction.

I just have to figure out how to afford it since my job terminates on Tuesday.

Thank you. Is the "Respironics proprietary DC cable" this one: https://www.cpap.com/productpage/DC-Pow ... Bipap.html??

What pressures do you use it with, and how long a usage do you get?

Have you, perhaps, tried the solar recharger?

Well, that makes two of us. Or three, if we count BB in on this.

I have looked at the Respironics battery, but Respironics themselves told me it was likely inadequate for a Bipap ASV. The set up I've referenced several times now (https://www.cpap.com/productpage/DC-Pow ... Bipap.html) was recommended by CPAP.COM and by Respironics as what I needed. Apparently, the ASV uses 24 volts and requires a step-up transformer, which is what this gadget is, in part. I don't pretend to understand.

Travel is important -- especially if I am evacuating for a hurricane!
