Optima Yellow Top?

[Overdrive]

Just wondering if anyone has put an Optima Yellow Top in their Boxster, and if so, if you could tell me what particular model you used and your thoughts. I'd like to drop one into my car if it's possible. Thanks in advance for any replies and insight.

I don't think they make a reverse pole version of the yellow top so you might need longer cables.

be sure you get the model with the posts on the correct side. (34R)

Also you'll need to make or buy a mounting plate kit.

And you may need a slightly longer grounding wire.

I did it and was done in 30 minutes of actual work. Never been inside a Boxster battery mount before. No special tools. I was about 65 at the time.

I ordered online with shipping included and it was cheaper than local purchase. I wrote up the procedure at https://sites.google.com/site/mikefocke2/batteries

While you are in there, make sure your 2 front drains are clear.

a radio and a/c on with the racing batteries let alone starting the car in cold weather. Great for racing as they are light and the weight is high. But the reports I read say not really practical for daily use.

mikefocke, thanks for the info, I will definitely check out what you posted.

The position of the pole connections is something that concerned me, as I know someone who ran into that problem when purchasing their yellow top (though it apparently came with a plastic mounting plate included that raised the battery up to the proper height, which would've been nice had the poles been in the right position), so if it's not all that involved I'd definitely like to do it and have the peace of mind of having a battery that can handle all the heavy draws (like operating the top) and things that run constantly on this car.

Thanks again!

EDIT: I decided to take a look at your link in the same sitting, saw that you listed the Battery Tender Jr. as a good item to use. I do have one of these that I use more for the bike's battery, and just ordered the cigarette adapter that I'll need to take care of the car battery over the winter...now if you we could do something about the 2+ feet of snow lingering around here...

It seems that D34R is a tricky item to track down, mike. I checked that 1st-Optima link you supplied in your writeup, but they don't seem to have it listed (only the D34 and D34/78). Do I have to contact them and ask about this particular model?

EDIT 2: Um...or am I mistaken in my thinking that they actually make a D34R Yellow Top? I see it listed under the Red Top, but I was looking for a Yellow Top...would be disappointing if they don't have a reverse one of those...

I think the litronics would be the larger issue
