I've been using an ATX12HD RS for years.
Other friends plus our E46 M3 have used an ATX20RS, without any issue for a few years.
Still highly recommend!

The batteries last at least as long as lead acid with the low usage I put them through and the restart has saved me tons of time with how frequently I forget to trickle charge.

I have never hooked my 370ztt up to a battery tender. I do watch the bluetooth charge module to tell me when I need to go for a drive.

So the battery showed up last night and threw it in the car. The weight difference is comical. The Antigravity battery is so light it almost feels fake. But so far it works great. I just hope my wife never finds out what i paid for this battery

I opted for the 30Ah battery so that's a difference of 29.15 lbs.

yeah, the physical dimensions are only a bit smaller but when you pick it up it's shocking how much lighter it is

damn thing might get yeeted if you aren't careful lifting it the first time

is there another part of the car where you can lose 30 lbs that easily?

If only I can lay off those burgers..

You had no issues of it moving around out on track? I tightened it down as much as I could. Your pictures look the same as mine. There is a good 2-3 inch gap in front of the battery.

I have been working on my Z lately and have been redoing my battery compartment. As my anti-gravity is still going strong in my GT-R, and my Z's DieHard battery has failed, I put my stock GT-R battery in it. I am hoping to have some time to make a simple mount kit for R35 sized battery cases into the 370z in the next few weeks. I am not aware of anyone having issues with the R35 size Anti-Gravity I sold them sliding around, probably partly because its so light, but I have been wanting to get it fixed solid and proper in there all this time.

A simple 3D printed plastic tray insert and maybe even a top piece will work. Suprised no one has mentioned it. is it expensive? or readily not available?

No, these days 3d printing simple parts like that is very cheap and very available. You can actually just brace it with a small piece of wood or MDF or use threaded rod and nuts for a tie down. There is no shortage of DIY ways to keep a battery stationary.
