I have just replaced the Optima red top in my Suburban.
I replaced it as it was simply cranking over the big engine slower than normal.
It has never given me any issues and the Sub always started and charged just fine.
As you can see it was manufactured in June of 2005 so it is 6 years old.
It has 910 cranking amps above 32* and 720 cold cranking amps when it is freezing out.
It has the top posts and side terminals as well, the Sub uses the side terminals.
I am asking $30 for it.
Thanks for looking.
