Talked to a technical representative today. Salient points:
1) Recommends 40Ah for margin vs parasitic loads.
2) Re-Start is an emergency over-discharge feature, should not be frequently used to recover after long storage periods.
3) Battery should not be left on charger during long storage periods.
4) There will be a sales promotion on 11/27/20, day after Thanksgiving.

 

My 24 Ah is working just fine with parasitic loads. Not good advice.

 

Hi @AlOtaBblGm
Can you please confirm that "positive left" is the correct option for terminal orientation on AG-24-RS?

I think "positive left" means the positive terminal is on the left when the terminal side of the battery is facing the observer.

Pep Boys shows "positive right" for batteries fitting our car, but I think they are wrong.

 

@ChpEng if don't want to install it upside down... Be sure to get the one in this orientation..
Seems like on their ordering page you select Postive Left or Right.

However be forewarned it moves the cables forward towards front of battery vs towards firewall..
For example red top optima does not have that luxury, so when I ordered their group 25 I had to flip so the cables are in line with OEM spec towards firewall..

You can use the pepboys or Costco interstate battery links to see what I'm talking about on standard batteries in 24 / 24F layouts.. Use an 08 IS F vs 08 ES350 as they go in oposite corners.

Hope that make sense... When you go with a non standard replacements you run into universal fitments that are not as ascetically pleasing.. The battery below would be great if they flipped their labels.



^^^ I wouldn't order this one...




Get the one in this orientation, sticker / label will be upside down but the terminals will be in OEM spec locations

So the issue is with antigravity they aren't clear, and don't have specific pictures of where the positive terminal is.

When I spoke with them they mentioned that the orientation is in regards to the battery terminals towards the front of the battery. If that's the case then the positive would be left, and turning the battery around with the posts towards the rear would place the terminal on the right. That is at least what I remember from memory, would be best to try to contact them, but admittedly slightly difficult at this time.

 

I called yesterday and confirmed this. The correct fitment is positive left, which places terminals closest to firewall and labels/stickers upside down, exactly as shown in @AlOtaBblGm's photos above.

Thanks @Joe Z for reference to Interstate, their MTZ-34 seems like a great option for an AGM.

Happy Thanksgiving to all!

 

@ChpEng if you're a Costco member see if they have the Interstate AGM in 24 as well.

Agreed guys..!!! As seen in post 1... Label flipped around, but terminals where they need to be



As seen in post #1

Happy Thanksgiving.!!

So with my battery on the way out, I called costco for a replacement and I wanted go AGM. And, funny enough there is apparently an AGM battery shortage. With less people driving, batteries are going flat, so interstate at least has shifted to conventional batteries only for now. They had told costco that they were going back to AGM production November but my local costco hasn't seen AGM shipped in early summer at best.

That's kinda the reason I'm considering this. AGM's run 190ish with costco's great 3 year warranty. Antigravity Lithium has a 5 year warranty, but I think they said 8-9 years was reasonable estimate. So you can consider the lithium being roughly 3x the costco battery, three replacements would put you at 570 (if the battery lasts 3 years and one day), it kinda makes a little sense getting the lithium then, as you get the weight savings and it's not that much more than the AGM equivalent over 8-9 years, ESPECIALLY if you take advantage of the BF sale. Now this of course is assuming it actually lasts 8-9 years. If it quits at 5 years and 1 day...well that's going to suck. On the other side, if the costco battery dies before 3 years you're getting a free replacement.

 

Antigravity Group 24 at 30 Ah showed up today. Perfect fit and much lighter than any lead/acid battery. I paid $750 for the Antigravity battery with a CTEK charger (normally $85) using the Black Friday discount. Life expectancy is 10 years, so longer than most people keep their cars. It can never spill acid in your car. The terminals won't crack and release hydrogen to corrode your battery terminals. If it ever drops below normal voltage, it disconnects the internal cells until you invoke the restart feature to start the car and start charging again. Best of all, it's a super quick way to lose 30 pounds off the car's weight. Sure, it's not cheap for the initial outlay, but the value proposition is unbeatable.

Oh, bonus - they send you a Bluetooth battery monitor to connect to their app on your phone and monitor battery charge, starting voltage, and charging system operation. Buying this by itself is $35, but they send it with every battery they sell too.



Weights below in pounds and kilograms as received from Antigravity.

 

Waiting on mine right now, pity because it looks like I won't be able to get it in, in time for the F day track meet later today.

 

@lobuxracer Which car is this one going in ???

Joe Z

 

It's in the IS F. The Supra is getting the little battery because it benefits more from the low weight. Just for you Joe, you'll appreciate this install. No, it didn't come with the stickers like this.

 

Nice you flipped the stickers... Well done..!!

Did you cut openings into the terminal covers??

Mine was challenging too when I installed the eyelet ring terminal connectors for the tender.

Final install on mine.. For the hidden look. Don't mind my upside sticker







Joe Z

 

I would like more videos of those with antigravity batteries starting up their cars

 

I slotted the terminal covers. They're available to replace should it be necessary. Just recently did this on the Supra. The 27 year old pieces were pretty ugly after all these years.
