im in the market for an optima yellow battery, but just don't know which size to buy

can someone point me in the right direction?

i think they're all the same

 

i guess it's not really size i'm looking for then, i guess what i'm asking is do i get the D31, D34/78, D35. D51, D51R?

I did a search and found a few people saying get the D34/78 and a couple others saying to get the D51

can someone clarify?

I'm doing this battery upgrade mainly b/c of stereo system, that's why I have decided upon yellow.

 

The 51R is the small battery used if you go with the Supercharger. If you're in stock form, I think the RED75/35 is a better alternative.

 

Go for the 34/78, make sure it comes with the spacer since the battery sits short. Add the spacer and replace the battery as usual. Works nicely.

 

Dustin-
Do you have the Optima as well? if so, which one? and where did you order it/pick it up from?

34/78 and yes make sure to get the spacer. Check Costco or AutoZone.

 

Thanks all.

 

You can kinda see the spacer in this pic.
