I'm looking for a UPS that'll last a couple hours at least. It'll need a battery pack of course. Links would be much appreciated!

Are you able to hook up two battery packs to a UPS? or just shut down and switch them over...

Anything around 500W-1000W would definitely do it.

Thanks,

The one I picked out only lasts 20-40 minutes. That's kinda why I asked here, are there any that last a couple hours for home use?

What are you doing that you want a couple hours from a UPS?
 
I will echo Paul's question. Are you positive that you need a couple of hours on battery backup? That sort of goes past the intended use of a UPS. You'd probably be better off with a generator if you needed that kind of backup. Heck, it might even be cheaper too (minus the fuel of course).

Home use usually means "Keep the computer running long enough to shutdown safely". If you want two hours, you need a serious power backup. There are industrial computer solutions for that.

If you're serious, look into places that sell off-grid power equipment. You are somewhere between industrial computer power backup and the kind of setup that can save solar or wind power on a small scale. A friend of mine has a system like that based on two deep-cycle 12V batteries (look like a car battery but better long-term performance and no short term high-amp starting capability) and a combined charge controller and inverter to convert 24VDC to 120VAC. You can connect such a rig to mains power instead of a solar electric panel or wind generator. Expect to pay something like $500.
