Lightweight battery

Swapped in my Antigravity battery today with only 54 miles on the odometer. It was easier than expected, taking about 20 minutes. I also added their "battery tracker plus" bluetooth module that's fun/helpful for data nerds. It graphs your voltage, cranking amps, temp, GPS if you forget where you park your car, etc.

My Emira is now ~30lbs lighter and my wallet $880 lighter :ROFLMAO: but I feel good knowing this will perform much more reliably than the OEM battery and probably last 10 years or more. Plus it has a reserve jump start capability which is huge if I forget to unplug my dash cam with parking mode running for a few days.

Did you install the screws on top or no?
 
Yup I’m doing mine now I just got my antigravity in.

It’s got 2 options 12v vs 6v and AGM/flooded vs Lithium LiFePO4

So I selected 12v and Lithium LiFePO4

For those that have installed it have you noticed small movement laterally? If I push it hard it moves slightly, wondering if this is a problem during lateral force when turning.

Yeah, I noticed that also on my first attempt at tightening the bracket, so I figured the Antigravity battery's lower lip is a bit smaller than the OEM lip. I placed a thin strip of self adhesive rubber (not foam) on the inner slanted section of the bracket and that secured the battery firmly in place. Hope this helps.

You think heavy duty double sided tape would work too? Idk what’s safe to put by a battery lol I know it’s only the bottom.

It probably would work, but do you really want to have the aluminum bracket glued to the battery lip, instead of just glued to the aluminum bracket? Also, depends on the type of double sided tape you plan to use. I don't think it's a matter of the battery's safeness, as they are well insulated, but the Emira's trunk does get very hot and, over time, the frequent exposure to the heat, could deteriorate the foam type, thus my suggestion to avoid it and opt for a rubber type trim instead.

Something like this from Amazon would work great...

I’ve had it installed for 8 months and it’s nice and tight in there. No issues when turning

Maybe you’re not driving fast enough ;) lol jk.

It’s tight but with some pressure it does move slightly. More of a peace of mind to ensure it’s not moving at all is what I’m trying to achieve.

Yeah I ordered some other rubber 1 sided sticky and the other grippy.
 
Nope. Fires right up.

Also there's room on the outboard side of it, so that's there the extra battery for my dashcam lives.
 
Anyone else who has done the 40 antigravity notice it takes just a little longer to fire up?
I haven't noticed the slightest difference to the OEM's start up speed or 1st time consistency.
 
Maybe it’s in my head, first time was fine started no problem after I charged it and the installed it soon as it got to 100%.

Next day it’s fired up first try just seemed slightly longer idk.

I do have the 440 tune, I don’t think that has to do with anything.

I’ll try it again after couple days and see.

FYI- it’s not on a battery tender yet. Seeing how it does without it. I would go 1-2 weeks without starting OEM battery no issues.

The Antigravity's last resort remote start works really well too, should it drain to the point of not firing up with the car's flip start button. How do I know? I left something on accidentally overnight which drained it, and the next day, using the remote, it fired up on first attempt, saving my hide. No need to use that emergency manual pull anymore..

Would the button on the battery work too if you don’t want to carry the remote?
