i have done an extensive search and have yet to find a definitive answer...

i want to put an optima yellow top in my 06 xb stock location with no (or as little as possible) modification...

what size do i need to purchase?

thanks
dan

 

well part of the problem with this is you will need to extend your + terminal to run the optima battery.
other then that just put what fits, all the optima batteries are fairly small.

 

yeah i heard you have to extend the terminal...how is that done?

also, i know they are mostly all small, but which fits our car the best? i know people on here have installed them...

I just went to advanced auto parts picked up one off the shelf and they put it in for me.
heres a pic of mine
hope this helps some?

 

yea the reg size that you can pick up at any parts store works fine, they make a HUGE one, and a small Honda one, also. You don't HAVE to extend the terminal, you can just bend it to get it on, look at Big Hungry's pic and you will see what I mean, I have had mine done that way for over 2 years now with no prob what so ever. You will need to use the plastic tray that comes with the battery to space it up so that our factory battery tie down rods will not be to long.

if you insist on extending it check here.

has anyone used the blue top?
i like the extra posted on the blue top, i know its not a starting battery.

 

thanks for all the replies...

bighungry--any chance you know the model number on that battery--that is the one i will go with!!!

thanks a ton

its the D34/78 the same one that you can pick up at any Auto Zone, Advanced, etc.

and they are all about the same price at those locations, with in a few dolors.

 

and the good thing about that model is that it has the GM style side terminal allowing you to add stuff on the side and not have to cram everything on the top.

 

OK, since there is not a lot of definitive info out there on the Optima battery. I did
a little research and a little engineering. I bought a yellow-top 34/78 battery and installed
it today. I ordered these parts from McMaster.com

#7752K41-stud to post terminal converter ($6.00)


#69645K58 - crimp-less battery terminal connector with 3/8" stud connection($2.32)


#98760A112 zinc plated steel hold down bolt, round "L" end 5/16-18 thread, 10-5/8 length pack of 2 ($7.41)
(no picture)

(these where way to long but they are threaded all the way down and I measured
them and cut them off. The factory bolts are long enough but they are not threaded
down very far)


I mounted the terminal connector to the post converter


and then mounted it to the battery thus creating the required offset. This eliminates
the need to bend the positive terminal and fuse block.



and there we have an Optima Yellow top all snug in my xB. I hope this helps others.

 

The yellow ones are for boats and RVs not cars. The proper one is the red top.

 

you got it all wrong, Jeff.
the blue is for boats, red and yellow are both for cars, yellow is better for cars that use a lot of power, cause they can recharge faster, and recharge back to 100%. The red is more for big trucks (duramax, cummins, etc) that need high cranking amps.

Try again. The blue one is the marine battery. Try researching before you post.
I would go here if I were you.

the blue one is better in my veiws, ever optimas web page said it combines the advantages of both the yellow and red

 

I asked about them at Autozone and this is what they told me. I should have known better than to believe them. Sorry.
I may get a yellow one when I add my PS2 and 17" flat panel to the rear hatch. Looking forward to GH at shows.

 

I'm sorry to say that the Autozone guys only got their jobs because they don't Know squat about cars.

How is the little boy in your Scikotics chapter that got run over? He going to be OK?

 

WOW, RUN OVER!!!!

 

He is back home and doing great. I'll see him hopefully this Sat night at our meeting. Thanks for asking.

 

Good to hear he is back home. That sounded like a horrible experience.
