So can someone clarify the difference between the red top and the yellow? Yellow is for sound systems and the red is for CCA (quicker start etc)? thanks.....

The Yellow Top is a deep cycle and cranking battery. The Red Top is primarily a starting (cranking) battery. If you tend to run high powered equipment with the engine off (utilizing the deep cycle functionality) then I'd go with the Yellow Top. If not, the Red Top will be just fine.

Do not get a yellow top, looks like you only get 1 year free replacement versus 3 with Red top.

Warranty info from the Optima site:

lol, why post all that jazz with no time frames?

Let me help you out, info from optima's websites.

OPTIMA YELLOWTOP WARRANTY INFORMATION
D34/78, D75/25, D34, D35, D51, D51R Automotive, LTV, Commercial, Car Audio 12 Months Free Replacement, Remaining 12 Months Prorated

OPTIMA REDTOP WARRANTY INFORMATION
12V Passenger Vehicle / Light Truck (noncommercial) 36 Months Free Replacement, Remaining 36 Month Prorated

Pretty simple to make out. Redtop warranty is alot better. This information exactly matches what Autozone's website states.

Now that this is settled, I would never recommend buying a yellowtop as the starter battery. Your up ****'s creek after a year. $200 for 1 year warranty is pathetic.

Over the past few years, I have heard so many horror stories about Optimas,from different car owners, I wouldn't touch one with a ten foot pole!

yellow is a deep cycle battery that's better if you have a lot of accessories.

Size 34/78 is $140 at Sam's Club and fits without much effort.
