Yeah, I had been looking at some videos of those projects as well, people making electric bikes and whatnot from old li-ion cells from laptops. Cool stuff, but when you see the price of UPS's nowadays, maybe it's worth investing as they don't cost more than 150 bucks. (this is for offline UPS, On-Line ones are much more expensive.)

Yea but they only last like 20 minutes and being they use lead acid batteries you could get more electricity stored in the same space with old laptop batteries. Also something I looked into was using an old UPS for $20 with no battery then adapting it to take a lithium battery.
