Looks to me like not only did he use the plain 34 but he actually might have used a 34/78 which is just a touch deeper.

Suggestion

If you look at the link to my installation instructions on Renntech (which uses a plastic mounting plate), the battery is more toward the center of the plastic mounting plate, so it might actually reach if you used a non-R Optima.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Which battery of the optimas has the four holes in the base for the yellow dog/other plate AND the correct terminals. 34R? Thanks. (can you get a yellow top with the 34R size?) jeff

POST 2Original post

Quotes source post: 6436945

Yes to both. I have the 34R Red Top in my car. It looks as though the battery cables might reach even a regular (non-reversed) group 34. So if you can buy a regular 34 from a place where you can easily exchange it, you might want to give that a try.

POST 3Original post

Here is a link to my install https://rennlist.com/forums/996-foru...a-battery.html You need the 34R size. The stock battery cables will NOT reach a regular 34.

POST 4Original post

Looking at the photo of your mounting plate, I can see why the battery cables will not reach. The battery sits way off to the right on the aluminum plate. If you look at the link to my installation instructions on Renntech (which uses a plastic mounting plate), the battery is more toward the center of the plastic mounting plate, so it might actually reach if you used a non-R Optima.

POST 5Original post

Here's a link to "Rob in WA's post. https://rennlist.com/forums/996-foru...a-battery.html Looks to me like not only did he use the plain 34 but he actually might have used a 34/78 which is just a touch deeper. Anyway, I ordered the regular 34 and will be installing it this way on the weekend.

Only the red is available with the reverse polarity (34R)

POST 7Original post

Ok, so I installed the 34 Red Top today. It fit pretty well. Just drilled 2 holes in the stock pan and it went in no problem. However, if you can get a 34R it would probably be a little easier to connect the cables.

This is a source reference. Confirm exact model applicability in the original material.
