Anyone have an overcharging alternator fry a battery?

My only experience with this is once the regulator went bad and was stuck on charge. The gauge would let every time the car ran. The battery swelled fat and boiled all the liquid out dry. No other electrical items in the car were harmed.

I first replaced the battery since it was burnt toast.
The regulator was next since it was cheaper than an Alternator. Problem fixed and lucky for my young & broke wallet.
