might be a bit late, but the exide part number is 54D not X54D the 54D is a good battery 460cca and a two year warranty. its also the OEM battery for the falcon on the other had the X56D is a much better battery and worth the extra money 550cca and a three year warranty. also a sexy red top lol. There also both made in Aus. the supercharge are imported just thought I should point out. I do work for exide, and may be a bit bias
