Garage
Optima Owners - which size are you using (and why?)

Time to replace the LARGE Die Hard with a new battery (battery died last weekend, so I'm due). I've checked the charging system and am getting 13.6 volts across the battery terminals, so I'm pretty sure its just the battery.

I'm pretty much decided on the Optima, but the question is, which size Optima Red Top?

34/78 with CCA = 800
75/25 with CCA = 720

Car lives in the garage and the outside temps almost never go below freezing.

Yes, I've searched and haven't found a consensus on the size.
