07 PT Cruiser Start Issues

The reason I suggested the load testing is I had 3 batteries go south in less than 10 months. I had them try to load test them after charging & it said internal short. I had the 4th battery load tested before I took it & tested good. It's been going strong for 4 months now. The battery manufacturer got my name & number from the people I buy my batteries from. They called & said the had a bad batch of batteries during the time of my problems & said there were a lot of others because it is a very popular size. They sent me & a bunch of others a 50.00 Visa gift card for all of the problems. I'm not going to mention who the manufacturer is because other than the 3 batteries in my truck, I had great service from plenty of their product line.
