Just replaced my oem batteries yesterday with the Duracell batteries from Sam's Club. I got a quote from the dealer for $155. 00 each with a 5 year pro rate, no free replacement period. He said they increased the cca to 800 or 850.
The only number I couldn't find on the Duracell batteries regardless of where I looked was the reserve capacity. The oem batteries have a RC of 150.
