Just to be clear, overcharging isn't 'boiling,' like boiling water. The 
too-high charging voltage causes the sulfuric acid electrolyte to release 
hydrogen gas; the bubbles are the result of a chemical reaction, not heat. I 
don't remember the equation but, basically, you're releasing the H2 from H2SO4. 
The SO4, 'sulfate,' will settle to the bottom of the battery and short out the 
plates.

Thanks to all who replied! 

It is always a learning experience for me when I deal with a new issue 
with my Roadsters. (learning to be a petrol head one issue at at time.) 
I didn't know it was the actual boiling of a battery that caused the 
release of the dangerous gasses. 

I was told some years ago that you have not had a complete day until you 
have learned something new. Yesterday was a comlete day! 

PEACE :-)
