help me brainstorm(atv battery)

I have a 12v atv battery that came out of my brute force 650 atv laying around.I was going to sell it but started thinking that since it's 12v maybe I could do something with it.....Its nice and and small so it could be crammed anywhere.
Is there any chance that I could turn it into a booster pack to jump dead batteries in an emergency?Or does it not have enough cca's for automobile starting?Probably not...
Or maybe a portable aux. 12v power source for powering camping stuff.....
another idea I had was to use it to power my cb.Think portable.:dunno:
