Thats awesome..... I have the Same Exact batteries in my Axis. I did a write up about them two years ago and they are still going strong.
I guess was lucky to find them around $250 each (in 2018) but when I checked out (local Battery Depo or Battery Plus - not sure which one) they gave me around 10% / 12% off at check out just for asking.
Yep they are heavy. I scaled mine in at 73# each (OEM was 46# each). Just barely fit under my steps with zero mods and just enough clearance with step door closed (1/2 inch?) - no tape needed for my application.
