Compaq Presario V2000 Battery
 

Have one up on ebay, great condition, barely used. My boss didn't like the double thick battery which raises up the back of the laptop (I would have loved it.) and wanted me to toss it up on eBay. May fit other models, not sure on which ones exactly, few listed in the auction that I found in others.
