Hey gang. I have a 2006 coupe with the stock battery in it and I am going to do a battery replacement this year before I hit the roads. I am looking into the Optima batteries, and see through the forums some people are using red tops and some are using yellow tops. After looking at the Optima website, it seems the yellow top will hold its charge longer, however I do have a battery tender so I'm not sure what the benefit of getting a yellow top vs. a red top is knowing that I can trickle charge the red top and keep it maintained. Next question is, the Optima website doesn't even list a yellow top that 'fits' my 2006 coupe. If anyone is using the yellow top what part number is it? The red top part number they say 'fits' is 25 (9025-160). Anyone with a yellow top willing to divulge this info? Also, if you have either of these and have any further info besides what is already out on the forums by searching the threads I would greatly appreciate it. Thanks in advance!
