battery blow up

My Problem

battery didn't work anymore. got a new one, realized, that the old one has almost doubled its size - thankfully, there wasn't anything else destroyed.

My Fix

battery was replaced in no time - was a bit disappointed that it only took a few minutes as I was prepared to work for half an hour or so. well the macbook is back in the "wireless-business"...

My Advice

open your device from time to time or you get full of dust...
