Yup but all the parts guy did was ask for the last 8 digits of my vin, then read me the battery I needed. So his battery for the ED (453-982-02-00) was the online battery for the gas smart, and the online ED (453-982-00-08) was for what he sold for gas smarts. At least the online site for 451's, either gas or ED is the same battery (the 451-982-00-08). When I bought my car, carfax history showed the dealer (a NJ dealer) replaced the battery. I'm wondering if they put the wrong one in. Or maybe it just doesn't matter. A clue would be what other people with 453's have., in both gas and ED smarts.
