Just noticed something on my new AC-Delco ACD75-60 battery. I'm a little suspcious this one may have been on the shelf a while. Stamped in the case is; 1FJ100 7:16. However, on the side info decal is small print: 0B08059-7/09, top decal has 0B030354-7/09. I'm thinking the 7/09 date may be the intro date for the battery series or something along those lines?
