Post #90554731 added 10-22-2016 3:25 PM by Dh3256 in Deal Talk
The point is that we don't know that, and because of the way the CPAP uses power vs the way a jump box is designed to provide power, we lose efficiency. As noted, this jump pack will start a truck,...

A regular lead-acid battery doesn't tolerate deep discharging well. They are not less efficient. A CPAP meant to operate on 12V will for sure go longer on this battery, whose capacity is about 5...

A CPAP draws lower power for longer periods of time, a jump box is optimized to provide high power for short periods. In lower power usage like a CPAP, the efficiency drops and a lot of the energy...

Oh, you are back for more lol. Sorry, still incorrect. Like I said, I'm not willing to spend the time to teach you about batteries, or correct your errors point by point. If you want to...

Not long enough? How do you figure? This battery's capacity is much higher than the one coming with the CPAP pack. Lighter? Yes.

A maintenance free car battery is a sealed lead acid battery. And both types of batteries is nearly identical except for the high pressure gas value. In any case, we are talking about this battery...

Yes, but probably not long enough to be much help. You would be better off getting a travel CPAP with a battery pack.

Nope, car batteries are not sealed lead acid batteries. Not sure why you are so confused about this, but not surprised you can't find any support for your opinion. Manufacturer's data sheets...

Sealed lead acid battery. Exactly the same. I'm done. Folks, don't believe me or Dh3256, do your own research. Lots of manufacturer specs sheet and even lecture notes from professors stating...

Here is the spec sheet from Yuasa, a 1st tier sla battery manufacturer. Take a look at the self discharge rate. At 20C, the battery will lose over 50% of capacity over 18 months, at 10C, about 30%...

The facts were stated in my post, so those have already been provided. The spec we normally use for lead acid batteries in industry is IEEE 450-210 . That is for stationary installations so it is...

No, if your battery is dead you use to to get it back up and running.

No, your example is not realistic at all. Technically true - the jump packs will discharge a bit if not recharged for YEARS, but will never self-discharge enough to freeze at any environmental...

I bought it for the other features, but would have been a golden purchase for me if I could clean my CPU fanbto boot. Guess not. Oh well
