Hi,
I'm wondering what would be the best solution for battery backup, in case of a power outage. I've read about the deep cycle marine batteries, and cpap.com does have the proper cables, but it does seem like maintaining that battery is difficult. Does anyone here use a marine battery? Is there an easier solution.
Thank you.

Marine Deep Cycle batteries win the "bang for the buck" prize in that you can get a 100 Amp-Hour battery for around $80. However, this is a heavy (50-60 pounds), flooded battery that needs frequent charging and watering (opening to little caps and adding water to the acid) and they can spill, so they are not well suiting to the bedroom. At the other end of the spectrum are the modern Lithium based batteries that are lightweight and easy to maintain, but very expensive and typically can't power a humidifier for long. As a compromise, I offer the following system that uses a mobility scooter battery and a quality small charger. The details of the system are the last post on this thread:JV1967 wrote:Hi,

Thank you very much for the help. Do you know which cables I would need to power up the Aurcurve 10 ASV, without frying it? Should I call cpap.com?

With the right charger, you don't need to add water very often to the battery. I use a Schumacher SE-1-12S charger and rarely need to add water. With a good charger, you just keep the battery on charge all the time.CapnLoki wrote:Marine Deep Cycle batteries win the "bang for the buck" prize in that you can get a 100 Amp-Hour battery for around $80.

I check my deep cycle battery about every 6 months and haven't had to add any water in a year or so.
The cheaper deep cycle batteries can be spilled. Non spillable sealed lead acid deep cycle batteries are more expensive. Whichever kind you get, put it in a battery box. The boxes are cheap, and even the sealed lead acid batteries can leak acid. The acid is bad stuff, but it's the same stuff as in car batteries, not some magic instant death fluid. Not a terribly big deal as long as you wash it off quickly and don't get it into the eyes. It will be bad for the furniture or carpet if you spill it.

My biggest problem with lithium batteries is that they have a bad tendency to die on you without warning, especially if you aren't careful with your charging and/or don't use them for long periods of time.
There are links to the ResMed info on battery usage in the Useful Links at the bottom of this post.
BTW, ResMed says you can use an inverter to generate power for S9 machines, but leaves this information out of the A10 information. It's not clear to me whether there's a problem with using an inverter with an A10 machine or if they just left that information out. Inverters will harm some older models of CPAP machines, such as S8 models with humidifiers.
