Yellow top is the deep cycle version and the D34 or 34/78 is the size for '03 - '06 (I have the 34/78). The Red Top is for starting only and is not suitable for accessory loads (radio, AC, etc.). Go to the Optima website and read all about them.

According to many that have reported on Optima batteries at this forum, choose the color that you will most enjoy seeing again after it goes bad in 6 to 12 months!

Who made the OE battery that came in my '01? When I bought the car in 12/06 it was still cranking strong, and I only replaced it a few months later just because. With an Interstate

Interstate and Diehard are both manufactured by the same company that makes Optima (Johnson Controls). Optima offers a three-year full replacement warranty as well.
Yellow if you have a lot of electronic accessories (custom stereo, etc.), red for starting with high compression, superchargers, etc.

Not much if anything. If you are looking to save weight look into Odyssey dry cell batteries. They are expensive though.
