Hello,
I am replacing the OEM battery in my 2009 Hyundai Elantra, a 121R. (13 Alaskan winters of service.) I bought a NAPA Legend on sale today "guaranteed to fit" my Elantra. The OEM battery is 8 7/8 wide, 6 1/2 deep and 8 inches tall to the top of the plastic case (8 3/4 to the top of the posts). The NAPA part number 75121R is 8 1/8 wide, 6 1/2 deep and 7 1/4 to the top of the plastic case (8 to the top of the posts). It will fit as the hold down doesn't know that it is shorter and narrower (left-right) than the OEM battery it is replacing. NAPA's website says this battery is 8.25 wide, 6.93 deep and 8.125 tall. I see different references to what a 121R should be online. Can someone tell me if I should be concerned/annoyed that this batter is quite a bit smaller that the battery my car came with? The cranking amps on the battery are correct, I just assumed that the replacements should be nearly identical to what came in the car. A misperception on my part? I browsed BCI charts and don't see a group that matches much closer, it just seems like NAPA (East Penn) is undersized for this group. Thank you-
