The Optima website recommends the 35 red or 75/35 red for my "99 SEL.

This car's fully loaded. I'd like to get the yellow top for it's deeper cycling. Which yellow top (model number) should I get?

Thanks.

 

I put the D34/78 yellow top in my 95. Its the one with the GM posts on the side as well.

 

I got the Optima Red Top 34R...Great Battery...A bit more money then the other units, but worth it

 

this is the one you want IMHO, I have it in my 97' SE' and it is a direct fit but you have to put a piece of MDF(wood you would make a sub box of) or something under it to make the hold-down work. it has both top and side posts so you can hook it up just as you would a stock battery and use the positive side post for your system and the negitive side post for an aux. ground.

 

I forget which one I bought but it came with a plastic adapter which gave it the ability to be a direct fit.

 

I bought the red top over the yellow top because,
A. its cheaper
B. red top has 3 year free replacement, yellow top has 1 year free replacement

Just something to think about.
