Which optima batt?

The primary difference between the red top and the yellow top is that the yellow top is a deep cycle battery. That means it's designed to handle frequent discharges without loss of capacity - in other words, you can run accessories (stereo or whatever) for longer without the engine running and the battery will recharge without damage. Normal usage (only occasionally running stuff with the ignition off) calls for getting a red top which has more cranking amps for daily use.
