Battery power.

After thinking about this and seeing the brochure, it’s lists a column for 12V batteries and a column for 24V batteries.
I’ll take a picture of it and post it to see what y’all think. I’m going to check on the coach tomorrow.
Since ours are 24V, I would think we follow the amp hours that I mentioned.

Which service do you plug your crap into? I am still lurking!!!

FWIW , I know you asked Mark but My Bi-pap is 110V so it has to be plugged in an outlet. I have read about 12V versions of the CPAP however. There are folks out there that are making Li Hybrid batteries now. That have 48V and 12V in the same battery. They use 48V inverters for the house side and 12V for lights and 12V electronics. The 48V side charges the 12V side of the battery internally while solar or shore or gen charge the 48V side. Technology is evolving in the Li world. They even have come up with one now that has its own internal heater that will kick in and warm the battery when ambient temps gets down to a dangerous level.

KK, I don’t use a CPAP.
Here is the pic that I took today. Had to go out to the coach to empty the holding tank and fill with fresh water. And, exercise the genny.
Sorry about the pic being sideways. That’s the page where I got the info on the amp hours.
If you click on it, it shows correctly.

All the CPAP’s I have had have 120 to 12v converters, the machine actually runs on 12v and you can buy a 12v plug for mobile use.

Thanks for posting Mark. If you have only gone down to 70% DOD (30% SOC) twice you are going to get much much more than the 2,000 cycles that they are rated. Interesting asterisk at the bottom regarding temperature and how it can affect life time and cycles but no expected life time is mentioned outside the number of cycles. I would think that 15 plus years should be doable.

Also interesting is the interconnect balancing batteries = yes , up to 48V
Humm, What could that be for , Built for future solar maybe ?

I have AGM batteries, and for almost 15 years have used them exclusively for house batteries. Like everyone else I want them to be trouble free and to last forever. But the reality is our batteries have a life span and eventually have to be replaced. What concerns me about the status of the battery world today is how to compare AGMs with Li batteries. I really like the reduction in weight. I would like to own a set of batteries I will never have to replace for 15 or 20 or even more years.
But those who now have Li batteries haven’t had them long enough to provide a true evaluation of them compared to AGM and I am not sure the economics have yet been proven. Worse, when I dig deep for information I am not sure the information available is entirely accurate.
XXXXX lithium batteries provide up to 10 times longer life than lead-acid batteries, and they still provide 80% of rated capacity after 2,000 cycles. Most lithium-ion batteries last five years or more. The average lead-acid battery lasts just two years. Lead-acid batteries also need to be maintained, requiring water replacement to avoid structural damage; if they aren’t maintained properly, their life span is shortened even further. Because lithium batteries require no active maintenance, a one-time purchase guarantees longevity.
The above is from a Li manufacturer’s web site. Since I reliably get 5 years from AGMs I can infer Li replacements either have the same life span, or to use the 10X statement I can expect 50 years. Which is true?
I am a power pole to power pole user, and when I am not hooked up to power I am driving or the generator is running. I do not work my batteries hard and it has paid off in trouble free life. If I were to replace the AGMs with Li, would they be the last batteries I ever purchase or would Li batteries used as I use my AGMs really last for substantially more years than AGM. I have heard many Li owners with problems and replacement in less than 10 years. I really like the weight savings, but for the cost difference between Li and AGM there has to be not only reliability during the life of the batteries, but a substantial gain in battery life.
How can we gather the information needed to truly understand the benefits of Li when even the manufacturer’s information seems unreasonable?
