I ordered the B2317 for it's 17# weight and it's 21# weight savings over the Optima that's failing on me right now. I guess I'll see how well this battery does. I'm cautiously optimistic.

Just a little info to save you a few bucks. That battery you ordered is a Deka etx motorcycle battery with brass automotive adapters. It has no where near 475 cca's. You are better off getting one from a Deka Battery dealer and buying the adapters.

I guess I'll find out soon enough.... it's already on it's way.

If it has no where near 475CCA - how much does it have, and what other product will be as light and DOES have the advertised CCA available?

(I hate false advertising)

Hahaha.... just so the cranking power doesn't go down when it's hot out!

The factory bracket that holds the batter up weighs more than this battery will weigh. Or at least it USED to.

Unfortunately when it comes to batteires, to increase the capacity the physical size usually has to change. I have yet to see an AGM battery in that size with that kind of cold cranking amps. Cold cranking amps is a 0 degree rating, the hotter it gets the better the battery will perform. Hopefully the battery does what you need it to do.

Thanks. Lucky for me - I'm more concerned about how it reacts to heat.

They refuse to let us race anywhere around here if the track temps get below 65°. It will never ever be used to try and crank anything at any temp below 45° to 50° anyway. I just hope it works fine at a heat soaked 200°.
