Battery Replacement Question 08WK3.7

WalMarts Maxx battery get a good review in CR but if I use their in store battery finder it shows a replacement number of 94R and the shelf # is skipped. It was the same online until recently where the online battery finder now shows a Maxx H7. I copied the dimensions and will check my WK tomorrow but I was curious if anyone else has installed this H7 Maxx and can verify it is the correct replacement?

Battery Replacement Number

I have an 08 with 3.7 engine. It has the original Mopar battery that identifies it as H7-72. I assume the 72 refers to months.

2008 JGC Limited, 4.7L.....Just put in the Wal-Mart H7 MAXX.
This is the same dimensions and a drop-in replacement.
I think it may even have more CCA than the original.

Oh, FYI....I had to stand on a stool in front of the battery so I could lift the old one out and install the new one.....they are heavy.........

Let us know how you make out.

94R and H7 are the same battery. They are different codes from different industry size indexes that are equivalent
