I need to replace my battery. If price isn't an issue, which is the best to get? I assume Optima - which one?

Any alternatives?

Thanks!

Optima is probably the best performance battery out there but they are pricey. There is no best one without knowing the application. Red and Yellow seem to be the ones people are going with but I've actually looked into the Blue top ones too. They are a deep cycle marine battery. Why you ask? At the track I run my battery down pretty low with my electric H2O pump and hi-speed fan between runs. A marine deep cycle might be the best if you constantly run the battery down and recharge it. Do you have a heavy draw stereo system? Many things to consider when figuring out the best battery.

Red has the most cold cranking amps for starting your car, yellow has the deeper cells which allows you to run accessories longer when the car is off

Thanks for the replies. I think the Yellow Top is the best one for me after more research. I tend to drain the battery at the track because of the water pump, intercooler fans, fuel pumps, etc.

Anybody know the difference between a D34 and a D35?

D34 D35 refers to battery group size. The actual physical dimensions of the battery itself as well as the CCA and CA.

The 34 shows more CCA and is 1 in longer.

Some also include side terminals.
