The pic on the spec sheet shows the pos term on the left. Maybe the pic is wrong.

Yes, I see what your saying....I checked the spec sheets and noticed D51R (yellow top) has the reverse terminals....I will call them again tommarrow and ask about the spec sheet. I will post as soon as I find out.

This is from source:thenewx.org

They say they do have a reverse yellow top optima battery.
the part number isOPT 8040-218.

That's the same as the discussed above. Looking at the photo in the spec sheet, it is not a reversed terminal. The photo may be wrong.

So I just got off the phone with Optima Customer service and they told me that their spec sheet for the Yellow top D35 is wrong. The terminal caps where put on wrong and D35 should be exactly the same as the reverse redtop model 34R...
So it fits!

just ordered my yellow top D35 for the X. Should be installed by this weekend.

Let us know what you do for a terminal extension. I went down this road last year and gave up on it. 4 wheel parts had 5 optimas delivered damaged so I gave up.

Will do.Actully Optima said it would be a straight swap for the stock one...I gues I will have to wait and see...
will post pics when mod is done.

The only thing I don't like about the D35 is the size, not the physical size, but the fact that it has less capacity.

As stated above, it seems that there are quite a few DOA Optima batteries now. Hopefully they fixed this problem.

That's why you don't buy anything made by Interstate Batteries. Optima's quality slipped several years ago when they got bought out.

Save your money, and buy an Exide Orbital. It's an improved design, cheaper, and overall better battery. Get the marine blue w/ dual terminals & quick thumb screws for the smaller posts for accessories, for the same price as you'd pay for an overrated Optima.

I dont get it what do you mean capacity?

Did you get that thing in yet?

Take a look at the spec sheet.

Compare the D34 to the D35. You'll see the differnece. The cold crank amps are higher, the cranking amps are hight, the capacity is higher, etc.

BTW - if the terminals are reversed, just install it upside down, and you're done.

Hope not yet. It was out of stock when I ordered it, might be here this weekend.

Battery is in, but didnt get a chance to go pick it up...Damn Santa claus parade...had to take my kids to it, so hopefully next weekend it will be in with pics...

so the battery is in...and I will post pics hopefully tommarrow...and for all you 05/06 owners yes! the D35 does fit.

So like I said here are the pics took me 15 mins to put it in....




any questions?
