Battery Back-up UPS

Linda3032 · Post by **Linda3032** » Fri Feb 16, 2007 12:15 pm

There's been so much talk lately about having a battery backup for our cpap machines that I thought I would pass this along.

Office Depot, for it's Presidents Day Sale has what appears to be an excellent price for a UPS.

And someone in the know can correct me if this isn't a good price, or if the unit won't run a cpap. Here's the ad, it's in-store-only. So you might call your local store to see if they have any.

Here is a link to the technical specs.

Doesn't tell the type of sign wave though. Pure or Modified?

Doesn't have a very long life when power is out. These types of battery backups are designed for use with computer equipment. Its purpose is to provide power so someone can shutdown a computer system (properly) in the event of a power outage. The battery backup unit is only there to save the computer system from being "unplugged" while all programs are running. Some of these types of battery backups even have software that can - once a power outage is detected - automatically shut down all the programs and the computer system itself.

For xpap I would want something that would last for many hours in the event of power loss.

Someone else please chime in. This does look like a very good price but don't really think it's good for xpap.

I'd be interested in hearing what's recommended for those of us living where heated humidifiers are the norm (arid areas).

Computer type UPS's have their place, and I use one with my CPAP that has a built in heated humidifier.

Much of it depends upon what type of power outages you have. If you tend to only have long duration outages then you need something else instead of or in addition to a UPS. During summer storms we get quite a few short duration (less than 10 minutes) power outges and my UPS works great to ride out those outages.

We can get an occasional outage that lasts for hours, and we even had an outage that lasted for three days. For longer outages, I have a small 12 volt powered CPAP, large RV type deep cycle battery, and a passover humidifier. In theory the RV battery should power my CPAP for at least three nights.

Me-thinks that the flow generator consumes less energy than the hotplate in the humidifier. I plug my APAP into the battery back-up side of the UPS and the heated humidifier into the non-backup side.

Checking out the pure vs. modified sine wave requirements of your xpap equipment BEFORE buying a UPS is pretty important. It would be nasty if you fried your xpap.
