Car batteries are not good for a UPS because they are not "deep cycle"
batteries (that is they don't expect to be drained all the way to zero,
which damages them)
I built a UPS for my wife out of a couple of deep cycle marine batteries
and a 600W inverter. We've got a solar panel that keeps it topped off. Can
run the laptop for days ...
