Only thing is to make sure you have a UPS rated at double the wattage you need. So when you hook up the car batteries the components can handle the extra heat.

What CM125 said. When converting UPS to use larger external batteries, you need to be aware of the charging characteristics & capacity of the UPS circuitry. The switching circuit/relay & fusing of the whole shebang also needs to be looked at & modified. If you're not familiar with how that functions, you could be setting yourself up for a disaster. Personally I'm not a fan of trying to do this with something that's designed for a smaller capacity battery. My Dad had a small UPS for his computer years ago. When it stopped working I disassembled it & found the battery bulging at the sides. Could have blown & caused a fire or corrosive damage. I don't think UPS units available for home computer back up are particularly well built. Be careful.

I use computer UPS too. No issues here.

Here is mine. You can use a battery or multiple batteries as big as you want to run DC equipment.
