Batttery pack ? for dummies, like me

While both you and I can build our own battery box can you believe there are folks who don't want to?

Your point about relying solely on reviews was discussed in the "Another Battery Option" thread and summed up pretty well here

Or there are a few Bone-Heads that don't read and follow the directions

You put your faith in the reviewers who you don't know and have no idea what their motivation is; we all know that competitors are forever disparaging their competition on the internet. Then you totally disregard the people here (on this forum) who have recommended this jump start battery for cpap use during commercial power failures.

This 22ah battery will easily supply 2-3 nights of service to most people and if more is needed it would be prudent to purchase either another jump starter or an additional battery (or both) which this jump starter can easily be connected to (using the jumper cables provided) so it can last as long as your wonderful configuration but is much easier to set up for people who are NOT as saavy as me and you.

There is no one size fits ALL - accept it.

Either suggestion works, although the Sears unit supplies all the power/time I need here in the suburbs for a power outage that will usually be no more than six hours or so, I must admit that I like the Captain's 35 AH battery for the extra juice. But bottom line is both end up simply being Sealed AGM Lead Acid Battery solutions in slightly different forms. I got the Sears unit for the convenience factor and I bring it with me in car and or boat as a spare jump starter in case I ever need it.

I have been using the Deltran Battery chargers for years to keep my motorcycle batteries charged during the snowy winter months, they are great quality and easy to use for charging batteries so I think everything that the Captain has suggested is great quality stuff.

I think the big take away from this thread is go ahead and get the 12 volt DC power cord for whatever cpap unit you own because that is a much more efficient method to run your cpap off a battery than using an inverter.

This thread has been very informative to me. I need some sort of battery back up and either the Sears or 35 AH sounds pretty darn good (sleepyhead term) to me! I like all the suggestions equally and now I have to choose. 35 does sounds pretty good for $150. Can't beat that with a stick! Well....hehe. 12 volt DC power cord! Check! I have never owned a battery back-up for my CPAP but I know that I need something. This sounds pretty good.

Make sure you get the correct 12V adapter for your machine - the PRS1 "50" series and "60" series use two different versions of this.

You keep talking about "building a battery box" but I'm not suggesting that. I'm thinking JohnBFisher did the group a dis-service with battery box description that made it look like a major engineering project. It isn't.

1. Bolt on color coded cables to battery. This is the only tough part. It does require a pliers, maybe two
2. Place in box. Not "build a box," just pick it up and put it in!
3. Connect several "fool proof" connectors. There are three connections; splitter to battery cable, charger to splitter, cigarette socket to splitter. Done. no solder, no splices, etc.
4. Enjoy.

The proud owner of the Sears is still trying to read the manual...

Are you claiming your device attracts buyers too stupid to read the manual? Maybe you have a point!

You put your faith in the reviewers who you don't know and have no idea what their motivation is; we all know that competitors are forever disparaging their competition on the internet.

Yes its all a great conspiracy! And only against your favorite product! You're too funny! Yes, a few people have claimed to have used these devices successfully. And there were many reviewers to that said their units worked. Maybe the odds of a good one are 70%, is that what you really want for your medical backup?

This 22ah battery will easily supply 2-3 nights of service to most people

Wrong! My test last month clearly showed a 560 with pressure 9, S1 humidity 3, heated hose 3 - in other words a pretty average setup - using almost 20 Amp-hours a night. Odds are the battery would be near zero in one night. Yes, if you woke up and turned off humidity and hose you could get a lot more, but that pretty much defeats the concept of using it in UPS mode. Getting an undersized battery might make sense if you're hiking, but there's no reason to skimp at home.

and if more is needed it would be prudent to purchase either another jump starter or an additional battery (or both) which this jump starter can easily be connected to (using the jumper cables provided) so it can last as long as your wonderful configuration but is much easier to set up for people who are NOT as saavy as me and you.

WOW! Listen to yourself! Yes, buy two or three! maybe one will actually work! And all those folks who couldn't bolt a cable onto a battery are better served by jumper cables in their bedroom. You are one big wack-a-dooldle, guest!

There is no one size fits ALL - accept it.

Then why do you keep recommending this one unit to everyone?

Funny thing is, I wasn't complaining about the concept, I think that's rather nice though the battery is a bit small; I was complaining about the reliability of this particular version, a few other similar units. But the more I use my setup, the more I'm convinced its within the capabilities of the readers here.

You do seem deeply opposed to giving the OP and readers a choice of their own while trying to make mountains out ideas that were not your own.

On the contrary, the readers are certainly free to make there own choice. I just feel they should be well informed about the gear they are purchasing and relying on. By claiming the harsh reviews are fraudulent you are not helping the readers.

By claiming fraudulent reviews only pertain to this product you are out in the weeds.

You certainly have a very biased way of processing information.

I resemble the "Tim Taylor" TV guy in that I overbuild everything often making it worse. I planned to construct a terrific battery in a box with all the neat stuff but didn't get around to it. To cover it in the meantime I got a jumper/power kit like the Sears unit in prior posts and haven't looked back. It apparently uses a bypass converter direct from AC to DC, and goes to battery without a blink.

One night the power went out while sleeping and I wold up when the APAP died. I had the humidifier and hose heater going and the battery cannot handle that. I used to have a F&P humidifier that had a short hose from the blower to the F&P then to the mask with the hose having a fleece cover. The F&P ran off of a separate AC plug so if power went out the F&P would just stop heating, but with the battery the blower run all night. The hosed cover took care of heating the hose.

I'm not sure even a marine battery built unit would run a hose heater plus humidifier plus blower all night.

My setup had no trouble running the pump, medium humidity and medium heating hose for a full night (my normal settings). My Amp-hour meter recorded this as just under 20 Amp-hours. In other words, I can run in "UPS Mode" where it will switch from AC power to DC seamlessly and carry that for more than one night. This battery was a 35 Ah scooter battery; most so-called marine batteries are 2-3 time bigger - 70 to 100 Ah.

Of course, if you were running the F&P on the inverter, then I can see a problem there.
