What would you do with a small collection of 18650 lithium cells?

This is my little pile of laptop batteries, made up of "18650" lithium cells - the same cell format Tesla uses in its roadster.

Even though I only have to collect 6798 more cells to make my own Roadster battery pack, I'm thinking that might not be a realistic goal.

The top battery was brand new last summer - right after I got it, the internal battery charger in the laptop died, so I ended up getting a new laptop.

The other two are old batteries of unknown condition - probably not too healthy.

I hacked them apart just to have a look-see. Never been inside a laptop battery before, or played with lithium.

Anyone have any creative ideas? I don't want to just recycle them if there's some other interesting life they could lead. What would you do with them?
