Need new start battery for GU - are the Optima yellow tops still worth it ?

[jff45]

I didn’t even look at the different variations available but I don’t think I’d have changed for a couple of extra holes. Most seem to run the yellow tops and the D31A drops exactly in.
With those multi connection terminals I got I didn’t really need connections elsewhere.

If it’s the same specs and you think those extra holes are useful for you then why not..

As far as I understand the M is Marine, stainless terminals and possibly a very slight CCA & AH difference but negligible. Dollars I think would be higher for an M as I seem to remember paying approximately 10% extra for my tinnies D27 years ago versus yellow top variants in other trucks.

Thank you legends!!

On paper, theyre the same CCA. Same everything really. One is blue one is yellow. One has extra threaded hole, perfect for a winch hook up and my upgraded Alt-to-Batt cable... 10-15 $$$ difference.
Had me stumped why blue-tops arent all the rage. ..

Well thanks to this thread I grabbed a D27F.
It dropped straight in and the terminals were in the right spot.
It'll do me as a starter battery.
