Red, any "sealed" battery will be a Calcium/Lead battery. I'm not saying everyone with a sealed batt will have trouble, just something to keep in mind. On the corrosion, I should have said any modern GM (80's & up) with the tray & frame rail corroded. This is from practical expeience. I've worked for GM for almost 20yrs. now. I've seen quite a bit. I had a customer today that reminded me of this. He wanted to know why his battery went bad so quickly. He had an aftermarket Antinony battery installed at a service station.
