So far I've had good luck with a red top (in an SVTF) but I do hear that the yellow is the better way to go. My alternator packed up on a NFS run (need for speed) at like midnight, I drove behind someone for about 20 miles on parking lights till I could find a safe place to park overnight, I came back after sunrise and drove it the remaining 50 or so miles home on the same battery. It easily took a full charge, and then drove it to the shop, again on the battery. If the Yellow is better it must be pretty good...
They make blue tops.......?
