Looks like I’m on the right track…

Replacement battery recommendations?

Well the cold weather appears to be taking it's toll on the stock battery. We have an 06 Off Road with big tow. The last couple of days I have noticed it doesn't sound quite as strong when starting. From reading other battery threads it seems like the stocker doesn't give much warning before it...

I wasn’t sure if I could trust the measurements on the Walmart site as the specs given in their descriptions varied from the picture with the diagrammatical measurements.

The measurements I posted were from either a universal chart or a battery manufacturer.

I also found a reference that H7 is also known as 94R. In which case odyssey shows 840 CCA vs 810 for their popular pc1700 ($440) but for “only” $340 for the H7.

Hmmm, cheaper and more CCA?

Edit: apparently the sizes are more like suggestions where a manufacturer can spec a battery group size and the vehicle should fit any battery of that group, as there is a maximum size any battery in that group can be. But for us tinkerers it means the brand might make a difference. I also read the style as in type (AGM, leaf acid, etc) can make/account for the variations in case size.

Good times. Off to Walmart with a tape measure, I’ll mind the terminals

 

I checked clearance with the 24F by putting tin foil fashioned into a cylinder (oriented like tin can on a shelf). I’m showing 2 1/4 inches clearance before the hood foam pad deforms it.

According to the Walmart site diagrams the H6 is only 1 1/2” taller so should work.

Just posting in case anyone else is out for a battery right now. I’d have used modeling clay but it’s too hard to bother with in the winter.

 

It may clear your hood but will your battery cables reach a extra 1.5" in height?

 

Good looking out, I’ll have to check :-/

 

Bumping this thread to confirm that the H7 fits my ‘21 P4X. Positive power is about .75-1” aft, but hooks up fine. No battery tray trimming, no issues.

This was an Interstate battery at Costco for $169. 800CCA’s, same price as the 750CCA H6 next to it.
