One last thing I wanted to touch on is chargers and battery maintainers as well. Now while there are scenario's where it's absolutely necessary (especially with lead/acid batteries) to have a tender/maintainer, it's not really ideal for any battery to be on one constantly. Really what it comes down to is that the battery is being unnecessarily cycled which in the long run is going to wear on the life of the battery. Lithium in particular has an extremely slow natural discharge rate so if the parasitic draw is low enough the battery can sit and be put on one only when it needs to be charged if at all. If it's higher or the vehicle in a location where it's not accessible for long periods of time then of course you'll want to use one more often as to not loose any settings or info dependent on memory retention.

I have the Antigravity ATX-30 in my GT3 5.6lbs. Works perfectly so far.

Hi Scott,
I have your ATX-30 battery in my car that I purchased from you earlier this year (order #45977). I've only used it a hand full of times as the car is a weekend / track car. Up until now it has performed flawlessly and has always started the car easily and without any issues but today I started having problems with it. I drove the car yesterday for about an hour and everything was fine. I went to start it up today and the car was totally dead. I popped the front trunk and went to check the battery voltage. It showed 0 volts. I then pressed the restart button and the battery came back to life and showed 12.87V when I checked it with my voltmeter. The car then started easily and I let it idle for about 10 minutes. Upon shutdown, the battery showed 13.14V when I put my voltmeter on it. When I went to start to car in a few minutes, it was again dead. Same process, I pressed the restart button and the battery came back to life and showed 13.13V. The car then started again.
I tried to call your support like but the mailbox was full. Can you please tell me what is going on with the battery? Obviously something is wrong with it since it keeps shutting off internally while the voltage is good. At what voltage is the battery programmed to shut itself off? At this point I'm a bit skeptical of it as I don't wanna keep dealing with a dead battery that I have to keep turning back on via the restart button and also having to deal with the electronic opening of the front trunk which is a pain everytime the battery shuts down.
I do have your fancy Li-Ion Optimate BC-OPT-291 battery charger/optimizer that I use on the battery. In case you are wondering, the car does not have any high draw accessories as it has no radio or other electronics. The Alternator is good and charging properly. I have a track event coming up in a week and hope you can shed some light on this so I can get this resolved as soon as possible. Thank you very much in advance for your prompt attention to this.

Great battery....finally ordered one.
What is the recommended charger since there are 4 to choose from on your web?

Hello, I have a question for Antigravity Battery poster. I do not own a turbo, I found this thread while searching for info on lithium batteries.
I have a 2009 Cayman S. I am about to pull the trigger as I am due for a new battery. And most of my questions have been answered in this thread. Except for one thing, I live in Arizona a very hot climate. My car is a weekend fun car and sometimes track car. It will likely never see extreme cold. But often in the summer I will take it for a drive at 105 to 115° But I will not track the car over 100°. Would this be a problem for this battery?
When I use your website‘s battery finder this is the battery that comes up for my car, “Antigravity H7/Group-94R Car Battery”. If I purchase today how long would you expect before it can be shipped to me in Phoenix Arizona?
Thank you, I will look forward to your reply.

You are correct on the H7 model and orders will usually ship within 1-2 days so it wouldn't take that long at all.

The temperatures in the Porsches are not really a concern ever.... this is because the battery is in the front of the Car without the heat of the engine around it.... Many of the other cars that use our battery have the Battery in the Engine Bay which creates a much higher degree of heat. So that is a use we expect and won't have a problem with. So the Porsche is not even a concern.
As for the Battery size... YEs you car does come with a H7... but the Porsches in most all models accept the H6, H7, and H8 sizes being they have an adjustable cleat. So while we prefer to keep the stock sizing, for any particular vehicle you can opt for the H6 size and it will fit as well but be about 1.5" LESS long (left to right dimension) ... but all other dimensions are the same.

Hi, I may be in the market for a new battery. What would be the best option for a 2010 997.2 Gt3Rs. Not frequently driven so it sounds like the 40ah is the best option. Would the H7 be the best option available?

An H7 or H8 AGM. The biggest one you can fit in there, on a CTEK tender.
