MacBook Pro battery flies off the handle, busts wide open

Heres the thing: that horrifically swollen, completely destroyed battery youre peering at above isnt as rare a sight as it should be. If youll recall, weve personally covered at least four MacBook Pro battery explosions, and weve also seen a similar amount of volatility over on the PC side. The story behind this one is as follows: a 17-inch (non-unibody) MBP owner was using his machine on a desk (thankfully), when suddenly an odd noise began to increase in volume; following that, the entire machine "jumped up" slightly and turned off, and this battery is to blame. Oh, and if this all-too-commonplace occurrence happens to you next, lets hope you arent actually using your laptop on your, um, lap.
