Ok, here is the whole story. yawn!
I bought a red top, and it would not hold a charge after 6 months. I took it back and got it replaced and bought another at the same time. Now, I have two of them. When I got home, I replaced the one that had come out of the car, and It wouldn't start. I tried to charge it, and it would not charge. I put the other one in and it started the car, as well as charged ok. I am in the process of getting it replaced. After 6 more months, that one is shot now.
After reading this thread, I am wondering if I shouldn't get the yellow tops instead. I will talk to the battery distributor.
