61 Watt-hours. That little battery could power a 60W light bulb for an hour!
(I'm currently working on a bluetooth -> IR bridge. I was worred about battery life from a coin cell, but now I'm not anymore. I will get one of these in half-AA size and keep the thing powered for the next decade :)
Batteries(maybe not these but definitely car batteries) are typically rated at the 20hour drain rating. If you increase the current draw you will increase the power dissipated over the resistance inside the battery and reduce the amount of available power in a non linear fashion.
