I must be one of the lucky ones. I have used them for 15yrs. I got 7yrs out of one and 6 from another.
I still have one in the GT and Cobra as well as my 92 Mercedes.
I'm not happy about the Made in Mexico. I'll be looking for a USA battery from here out. I'm trying real hard this last two years to buy American made products. Damn it's hard to do. But we got to start somewhere.
