Bill, did I say the Optima was a gel-cell? No. It is a spirally wound AGM
varient. I know I mentioned AGM batts. in my last post. I just re-read it. I
suggest you do the same. And I also mentioned that AGM batts don't have a
problem with high amp charging. BTW, AGM stands for Absorbed Glass Mat. I'm a
double E with over 23 years of experiance( with all things electrical, but as
you can see, I have yet to figure out how to turn the spell check on on my
son's computer...) and  work for a company called Exide. We design an make
all sorts of batteries, along with a lot of other nifty electrical gadgets.
We also make our own version of the Optima, called the Orbital. Nice batt.,
partially my baby. Any more questions?
Have a nice day,
Beckett
