In most of the discussions ehre I saw that mostly 49-DL or the 94R batteries were mentioned. I drive a 99, 323 IS and my battery died on me yesterday. I went to Autozone for replacement and after putting in my car details they gave me the Duralast 48-DL. So, should I use the 48 ? Just a little confused, since, like I said, everyone here seems to mention 49-DL .. Any suggestion ??
