458 Antigravity Lithium Battery Fail.

Got it.

So when you attempted to start the car, previously - using their re-start feature - did the starter motor attempt to crank at all?

Definitely a faulty battery. That is a test the battery should handle. Dan from Normal Supercar Guy did exactly that test with his 458. There's a video of him doing it on his channel. Do a small video showing your car not starting and sed it to AG along with a link of Dan's video showing the restart working properly.

It's a bit disconcerting when their fail safe system fails...

I'm glad they stand behind their product, but I still say upgrade to the Braille i48CS.

Indeed, but failures happen.

When they do, it is imperative that it is handled swiftly and properly.

You know I'm a big fan of Braille, and I think highly of their products. However, I cannot say that I have experienced the same level of customer care as that I have experienced with AntiGravity. A local guy had an issue with an I49CS in an FF which would not take a proper charge, and it was evident that it was the battery. It turned into a saga lasting for a month, during which we were basically told that we were idiots. Then after a few heated phone calls and a test done by someone I know in Bosch Automotive, they reluctantly took it back and sent out a new one. They still charged the guy for shipping the old back and the new out. It was 5 months old when he had an issue, and it's a 3000 Euro battery. That's just not good enough. I love their stuff and I stll think their AGM stuff is above and beyond, and I like their Lithium stuff too. But their service needs to be better, especially when you pay top price.

I have personal experience with a few AG,batteries at this stage, and honestly it gets harder and harder for me to justify the high price of the Braille CS batteries. The technology is getting cheaper and is developing, but Braille has not adjusted pricing for years. Maybe it's time they re-evaluate things a bit.

Having owned a number of companies myself, I definitely agree with you that customer service is often as important - if not more important - than the product or service itself.

I've always had top notch customer service from Braille myself.

The fact that Anti-gravity has jumped in here quickly to help resolve this situation certainly speaks highly of them as well.

Just to get you off to the best start. Charge the battery fully before you install it. It should read about 14.4 volts when at maximum charge.

 

I thought the AG battery just shut down just before reaching a voltage insufficient to crank the car. When the reset button is pressed, you have 1 start left in the battery which can the recharge while driving. Nothing more than that, but please correct me if I am mistaken.

 

That could be. I'm not really sure what method they are using.

So what's the latest in this saga?

Now attach it to a Li charger and let it charge to 100%.

Then you can remove the charger as long as you give it a good run once a week.

i recently installed antigrav battery and bluetooth tracker on my F12 so far so good. however it seems anyone can download the app and access my battery tracker and initiate crank/charge tests and change notifications. is there a way to restrict access to the tracker via a pin code or something similar?

 

My 458 sat at an airport parking lot for 46 days with an antigravity lithium batter. Came back and the car started as if it was sitting for just a day.

Separately, I left my emergency flashers on for 24+ hours and it drained the battery. Car wouldn’t start. Hit the remote button for the battery, gave it enough juice and car started right up.

Frankly speaking, that's amazing. My Ranger Raptor (2021 model) was recently shipped from one side of the world to the other. Reconnected the battery, started right up, and charged it. Wanted to move it to a different spot the other day (I'm still waiting on the registration documents), battery completely dead. It was sitting maybe 3 weeks, with a traditional battery.

To have an ''older'' car (as the 458 is right now, amazingly) sit for about twice as long and start right way says a lot!

 

I couldn’t get past this

 

When I started it after 46 days, there was no delay. As soon as I turned the key everything came on normally, quickly, not a single error, hit the start button and she fired right up without any clogging or delay. The antigravity lithium battery is the real deal. I’ll never own a car without this battery ever again.

For the starter of the thread with issues….these batteries are made in China. You probably just got a lemon. Swap it under warranty and you’ll be fine.

+1 on the Braille i48CS. I'm an Aerospace/Software Engineer in the defense industry and have looked at the AG "smart" electronics/software. I personally wouldn't trust it farther than I can spit.

 

Cool story bro.

 

It worked well for me, exactly as advertised.

Battery lasted 46 days and the Ferrari fired right up without being on a tender and just sitting there.

Separate occasion, battery died because I left the emergency flashers on overnight which is a massive drain. The car wouldn’t start and was dead…I pressed the button on the Antigravity key fob, the cars electronics turned on, I hit the start button and it fired right up.

The AG batters are excellent and their technology is a marvel that worked as advertised for me.

The OP simply got a lemon and should exchange it under warranty and not look back.

Has anyone had issues with ag batteries? It's worked fine in my ferrari and lambo for 3 years but I have one in my track bmw car and I just had two dead batteries

One they replaced under warranty, the second In less than 8 months while completely disconnected it went completely dead for no reason

I emailed them again just to ask if there's a known defect with the model I had and they never responded back.

 

I purchased an AG battery, and let it run out on purpose to see if the restart button would work. It worked just as advertised. Nobody mentioned it here, but it's also a very easy way to shed about 30 pounds from the car. You need to buy a LOT of carbon fiber to get an equivalent weight savings.
