Can this battery be housed inside my trailer?

If in a battery box and vented.

Can this battery be housed inside my trailer?

What is the point of this battery vs a $70 one from Walmart or Costco?

This is a UPS. Uninterrupted Power Source. It's designed for computer use to keep the power up long enough to save anything you might need before the battery runs out. Read Short Term, like 15 to 20 minutes. You'll be highly disappointed if you put this in your trailer.

It's also an inverter, meaning that the output is 120 Volt.

I thought this one being a sealed battery would be able to be stored inside without leaking fumes during charging. I can get these for cheap, and 110AH is pretty good.

Where did you get the 110AH rating. I see nothing on the web site about that. If that battery is an SLA 110AH and you can get it cheap, less than $25.00, go ahead and use them. I use a 50AH SLA for my ham radio that came out of a UPS.
SLA = Sealed Lead Acid.
Charging can become a problem, I blew up a 100 AH SLA by attempting to charge it too fast. I don't think it would be a good idea to charge while driving. If you the charge level is too low the high charge current could rupture the case. Be sure to put any battery inside a battery box so that if the case should become fractured the acid will be contained. Don't ask how I know this.

It is 78.3 Lbs and does not list the amp hours. Other than being heavier than most batteries we might use, we can't compare the amount of power it can provide.
With taxes it will be over $300, so why bother?

Roy,
I think he was talking about the battery inside the UPS. Companies that can't afford down time, cell towers, server farms, etc. etc. They get the UPS systems installed and replace the batteries about every 2 years. Many have lots of life left in them. Sometimes you can pick them up the batteries for nothing (those companies have to pay to dispose of them). There's a local guy that picks them up, then cleans them, load test, and sells them for $5.00 to $10.00 each depending on the size. I purchased 2 50AH batteries for $10.00 each about 4 years ago. One gave it up, the other is still going strong.

It's not a bad source of batteries, but you have to be prepared for it to fail at any moment.

ok, thanks for the info guys. It's good to know. I'll probably keep on looking for another type of battery.
