I’ve decided that because of my crappy power providers systems that I want a more robust backup battery system for my HE hub, Hue hub, Lutron Pro bridge. I’m going to be using a 12v agm wheel chair battery, I just need help with the parts needed and how to setup, if anyone here has setup a similar system I would greatly appreciate any help that can be offered.
Perhaps I shouldn't ask... but why not just buy a UPS?

I'd recommend simply buying an APC UPS, or similar. This way you'll be able to use all of the corresponding power supplies for each device without having to worry about stepping down the 12v AGM battery power to the correct voltage and polarity for each device.
There are actually 12v UPS equivalents out there. Belkin makes some that I purchased and use in my house.
It has a nice barrel plug and I just replace the normal wall wart for whatever 12v device I am powering.
My Hubitat is on PoE, supplied by my switch, which is on a normal UPS.
Hey Jeubanks I have a cyber power ups but my power company are about the most inept that I have ever seen in my life, I was born and raised in Md but because of my wife’s job we now live in Ga and these guys are just ridiculous the power goes out like once every 2 weeks for like a half hour to an hour at times sometimes longer. The WOF is wearing really thin because when things go out and stay out and she can’t work things she gets super pissed and wants to throw errrrrr thing out. That’s why I need something bigger that won’t cost an arm and a leg, most commercial upses for the size I will need will cost a fortune.
I have a couple of these and they work great and are affordable
That’s the exact one I have in my living room running my qnap nas and my netgear Orbi router I believe I paid $134 for mine at the time. I was just thinking a agm battery would last and run my devices a whole lot longer.
It runs all of my automation gear + network gear for several hours and I can (don't but can) connect to it and signal poweroff to my equipment if needed.
I went on facebook marketplace and bought some really cheap APC with dead battery and replaced the battery with a similar to your 12v agm wheelchar battery. The last time I tested it. it lasted around 5 days with the HE, ST, Lutron Pro, and a bunch of other network devices on it.

Huh that’s sounds very intriguing Navat604 could you share how you went about doing that? If you don’t mind.
This UPS needs 2x batteries
I did the same thing. Since a lot of companies nowadays run their stuff in the cloud a lot don't need a local server anymore and therefore don't need their UPS. So they dump them cheap.
I setup a bank of 4x 6V deep charge Trojan batteries (serial/parallel to obtain 12V DC), hooked to an intelli-power charger that keeps my batteries full all the time (as you know deep charge batteries like to stay at full charge even they can go low better than any car batteries).
Why not UPS ?
- my system can stay off the grid for days, not hours (I'm in Qc, Canada).
- most of my devices are 12V DC (router, switches, plc, ...) or can be converted to 5V DC USB, so no need to use the provided PS to convert 120V AC to 12V DC...
- I have some solar panels to charge my batteries bank when it's sunny
The only maintenance I have is to add a little deionized water every 3 months into the batteries.
The day my bank will be dead, I'll replace them with a set of LiFePO4 batteries

I have absolutely no idea what you're trying to imply or get at. The UPS Includes the batteries.
If he wanna use same UPS with dead battery and use his battery.
this specific model needs 2batteries.
Quoting and replying to me about another person's post about repairing a different UPS which was out of context to my responses to the OP is very confusing and throws any semblance of conversation out the window.
Perhaps reply to the OP or the other poster and reference my link but what I posted was an actual functioning UPS system not something to repair.
I understand what plantucha is saying the ups that others have pictured I have that same model now in use what is eluding to is if I wanted to use the model I have it takes 2 batteries originally so would need 2 as a replacement if I was to upgrade hack.
