What's the difference between T6 and H6? Antigravity website "Battery Finder" says to us the T6. I'm looking for my 360 Spider. Thank you.
I have the T6. It is slightly less tall than the H6, easier to install on our cars due to the metal bar on top... Highly recommend the T6.
Hi Planning an antigravity for my piloti. Can anyone confirm which battery fits? Also is is a direct drop in? .... Or is there programming involved? Thank you
T6/L2 for a 360. Best you get the 60Ah version. Perfect fit. H6 is slightly taller and tight fit but can be made to work. H6 for a 430. Sent from my iPad using FerrariChat
I put this in mine. I dropped 300 pounds of the car and the battery was actually some the cheapest per pound reduction. I was concerned about it being too small but have been pleasantly surprised by it. The car cranks very hard on startup and has no problem during regular use. I do keep it on a tender when at the house though, just as I always did with the old boat anchor of a battery. This only weighs 5lbs. As for the fire concerns I think that my phone is more likely to spontaneously combust due to the way its battery is abused daily. This thing gets the princess treatment.

15 ah is really small. How long have you been using it? I would be very concerned leaving that without a tender for more than a week or two. 40 ah would seem to be the bare minimum just to have a little reserve capacity. 60 ah would be more to my comfort level. I believe the factory battery is around 70 ah. Just checked now and here is what Antigravity recommends on their website: "Ferrari (use H6-60 battery; 60Ah Minimum due to higher parasitic draws on Ferraris)"
It’s on the tender anytime it’s at home. It’s just generally a bad idea to let the car sit for that long as it’s hard on the battery and the alternator even if the car does start after that long. It will negatively impact the life of both. It’s more than enough power to operate the car but yes it wouldn’t be optimal to leave unplugged for long periods of time. Saved over 45lbs over the stock battery and mount though so it was a must for achieving my weight goal. I did get the 60ah Antigravity for my 458 though as it’s a much more needy car, electrically speaking. I still keep it on the tender religiously but have gone a couple of weeks one time off tender, without starting it and it fired right up. I’d never do that on the 360 w this battery, but if weight savings is the overriding goal and you keep your car on a tender anyway no one would ever know my car has such a teeny battery. It’s fine idling in 100 degree weather with the headlights on and the AC on max with the cooling fans blowing. Sent from my iPhone using Tapatalk
It works for him because he has it on a tender. But for many of us, part of the reason to get an Antigravity is to be free of tenders. The Antigravity replacement battery versions have built-in battery monitors that shut them off if the charge gets too low. But there is a reserve. Press a button on the included fob and it unlocks the reserve. They also hold higher voltage and charge until they are depleted. So a lithium ion battery is likely to start your car and all electronics will function normally for a long time even if left off a tender. So unless you leave the car undriven for maybe a month or more, there’s no need to keep it on a tender. Also, you need a lithium ion-specific tender. I have one but rarely use it. Note also that unlike lead-acid batteries, lithium ion batteries don’t last as long when always kept at 100%. Finally, while it’s really cool that lithium ion batteries weigh a lot less, even a T2 or H6 60Ah will weigh significantly less than its AGM or lead-acid counterpart, and there isn’t that much advantage to shaving another 15 pounds or so by going to a super light weight model because it’s sprung weight. https://www.midtronics.com/blog/is-it-bad-to-charge-an-electric-vehicle-to-100/#:~:text=Charging%20fully%20can%20be%20bad&text=And%20just%20like%20in%20other,sets%20off%20a%20catastrophic%20failure.

All true. I do however think that the BMS doesn’t hold it at 100% of its actual cell capacity(even though it tells the humans it’s at 100%) because that wouldn’t really be managing the battery at all. I have no data on that though so we’d have to ask Antigravity to find out but it just seems weird that the would break that golden rule. My main takeaway from my experience is that Li batteries save tons of weight, even if you were to go up in amp hour rating over stock. The other is that the characteristics of these batteries result in very strong starting/cranking performance even when dealing with a way undersized setup like I did on my 360. Lots of things to consider(cost, weight, capacity)when buying a replacement but people definitely should not be against the technology itself. I’d bet that they’re going to be standard in the not too distant future. Sent from my iPhone using Tapatalk
I bought the hype and began transitioning my cars to Antigravity batteries three years ago. Then I found out that they discharge almost as fast as a regular battery so you still need the special lithium tender, you can't use a regular charger if they go dead (only can jump start), and worst of all the reserve isn't enough to start my cars. The AGs in both my 993 and my Lotus Exige 260 Sport died (2 months idle). The reserve was enough to crank the cars but not start them. I talked to AG and they said it can happen. I don't track my street cars so the weight doesn't matter, so I'm back to regular batteries.
Interesting.... My T2 60Ah lasted 2 months in New England cold weather with no charger, and started right up without the reserve trick... still had 12.2V when I got to it . This is the F430 . Your cars might have a lot of drain ? To put it into perspective, the AGM I have in the M3, which was put in about the same time as the AG, found it with clock reset after one month of sitting; which means the car shut off the accessories as battery voltage dropped under a certain threshold.
My experience has been like yours. 60Ah. No issues. Hardly ever use lithium ion specific charger. Sent from my iPad using FerrariChat
