Are OEM WH batteries AGM?

I guessing no room under the seats to fit one in?

In what way are you limited on space?
I've had a D34 yellow top and currently have a D34M (blue top) in my hemi, plenty of room.
Definitely not enough room under the seats in a WH... unless you're referring to the WK aka WK2 (this the WH/XH forum.)?

PS genuinely asking how you're limited for space, not having a dig at ya haha.

I am limited in room because the WH 5.7 drivetrain is under a 1948 Willys Truck body!

I found a spot above the mufflers with 25mm of clearance if I go as tall as 190mm. Length and width not a problem there.
Thinking maybe this one would exceed all the specs needed?

Aaah yes of-course! Forgot who I was replying to

Yep hemi electric gear would be sweet with that Start-Stop AGM one. Start-Stop batteries typically have the plates compressed together with more force, which should give some leeway if you end-up with more heat or vibration than a factory location.

I have moved my K member so I can get a 100mm more height between the mufflers and bottom of the battery now. So I can run any size I like. Might run a more common Land Cruiser 4wd one like the N70ZZLHD MF

Has to be a MF, maintenance free, as can't check the levels of the cells.

Speaking to the engineers there at Century they also recommended the dual purpose AGM one. https://www.centurybatteries.com.au/.../27x%20mf/info

On numbers alone though this one is hard to beat.
