batteries for machine

Post by Rick B » Thu May 27, 2010 6:35 pm

I did some checking on batteries online and it seems the 2 that stand out are the one provided by Respironics and one by BatteryGeek.net.

Does anyone have any information that would help me out. Have you used any of these? What do you use? These are really expensive batteries.

And what happens if I go without the machine for a few nights?

Dear Rick B -

Yes, the ones from Battery Geek really are terrific, however, yes, they really are expensive. My husband and I are both on cpap now and it would have been cost prohibitive for me to purchase (2) of these expensive BatteryGeek batteries. I reached out on the forum and a friend told me about the Duracell 600 powerpack (you can purchase it from Amazon.com for about $150.00. Here is the link: http://www.amazon.com/Duracell-DPP-600H ... 858&sr=8-1) You can't use the humidifier with it, but you can't with the batterygeek batteries either. My friend used it for 9 hours and still had 30% charge left. Of course if you have a high pressure, you might get less time out of it. My friend ordered it, charged it up, plugged in his cpap and tried it out for a night. It is a wonderful less expensive alternative. I have had some power outages this year and although not one lasted all night, I was worried about what to do if by some chance at some point it did. So, if you can survive a night without the humidifier turned on, (you could still put a bit of water in it but just not turn on the heater - this is called passover mode), consider this less expensive alternative. Our batteries are all charged up now and I no longer lose sleep over the what ifs. I do NOT recommend that you don't use your cpap in a power outage. Better to be prepared and have a back up plan with some kind of battery.

Best regards,

Jersey Girl

If you are using your Remstar it runs on 12 Volts. For my Respironics M Series I am using a 75 amphr. Deep Cycle Marine Battery with a float charger. I have over three eight hour sleep cycles with running the humidifier and still had plenty charge left. I started out to have it as a backup for emergencies and when I go camping. But since it is working so well I use it all the time with the float charger plugged in. The whole system cost me about $145 dollars.

I use the Respornics Battery pck for my M-series Bipap Auto. As a back up for here at my house and if I am not in my RV. I have 6 6v battery's in my RV and Solar on the roof so I have battery power for my M-Series.

More than you might have wanted to know about building a Backup Battery for your unit. My ASV unit pulls a lot of power. Plus we occasionally lose power for several days. So, I needed a battery that could last at least two full nights and possible three or four. So, I had to build a unit that would handle the power demands I had. You can see what I did and take it from there:

John
I built my battery system based on your posts, good job. I am confident that I could go at least four days without power, using my humidifier, probably seven without. I am thinking of building a electronic switching system/battery monitor, but I am waiting to see how everything works before I build it. Thanks again for all the posts they were a great help.
