I spoke with Bosch Tech support last week about spark plug recommendations for my car. Since I already had them on the phone, I asked who made their AGM batteries that are sold at Pep Boys. They said it was Exide.
Funny thing was they refused to provide information regarding spark plug choice but to contact the Porsche dealer!
I pass on the exide batteries as well.
I honestly can't believe people still buy their batteries because they usually don't last.
I try to get Johnson Control batteries or East Penn/Deka batteries
The Bosch Platinum from Pep Boy's does have a 4 year replacement warranty.
