Currently have a H6 AGM battery in my 2016 JKU. Will be replacing it later this year. Thinking of going with a H7 AGM battery. Looks like it should fit.

Anyone have any strong opinions one way or the other?

Thanks!

I have an H6 and attempted to do an H7 a few years ago. It will fit with some modification to the battery box by removing the plastic wedge that holds it down. Its also very tight! tighter than I liked and decided to just get a quality H6.

Did it cause any issues with fitment of the purge valve?

Thanks for the feedback!
