On the contrary - All UPS's I've seen use lead/gel acid batteries.
However, they are *SEALED* batteries.  

I would not recommend any kind of normal car battery that could give off
gasses or leak, but the sealed gel acid batteries are safe if treated
properly.  The alternative would be to put a car battery UPS outside, and
run some cables inside, but I doubt this would be cost effective, as
regular UPS's are not that much $$$.
