NEW! OEM Sized Lithium Batteries with Wireless Remote Built-In Jump Starting!

The first Intelligent Lithium-Ion Automotive Battery that won’t leave you stranded!

Antigravity Batteries has changed the game again with our latest Lithium-Ion Car Batteries. The newest RE-START line of batteries offers built-in WIRELESS Jump-Starting! That means if your battery is ever discharged, simply press the Button on our provided Keyfob, start the car and drive away! No need for a Jump-Starter, or Roadside Assistance. You don’t even have to open the hood of car to access the battery, and can do it from the safety of sitting in your car!





Our amazing RE-START Technology is the first battery ever to offer Wireless Remote-activated built-in Jump Starting. (Can also be activated manually by pressing Restart button on top of battery.) So it won’t allow you to get stranded with a dead battery! For example if you left your lights on, the intelligent Battery Management System (BMS) in each RE-START battery would put itself to sleep before being drained dead, yet save just enough energy to start your car again and get you out of that emergency. And with our WIRELESS REMOTE KEYFOB you can activate the Jump-Starting without ever opening the hood of the car. Simply press the Keyfob Button, start your car and drive away.




The Antigravity Batteries RE-START system offers the latest technology for the safest, longest life cycle possible. Our superior on-board Battery Management System (BMS) offers Safety Circuitry to prevent Over-Discharge and Over-Charge, and has Short-Circuit protections, while additionally offering Cell Balancing and Thermal protections. These advanced features of our BMS make the battery not only as safe as possible, but also extend the life of the battery by keeping the battery in the prime operating zone and not allowing damage to the battery. Therefore creating the longest possible Life Cycle. From 7-9 years are expected from the Antigravity RE-START Batteries depending on use and climate.




The Antigravity Batteries RE-START Car Batteries come in EXACT FIT OEM sizes for most all Performance and Passenger Cars. We are the First Lithium-Ion Battery company to offer the most popular BCI sizes including H5/Group 47,  H6/Group 48, H7/Group 94R, Group 35 and others. These sizes are standard sizes in most every Hi-Performance European and American Cars. So whether you have a Porsche, Lamborghini, GTR, Mustang, Camaro, Corvette, Viper, BMW, Audi, Subaru or other Performance Car, we have a model that can fit. But keep in mind Lithium isn’t only for Performance Cars; it works great in passenger cars too!



Weight: The Antigravity RE-START Batteries weigh from 8.5 lbs to 16 lbs (4-7 Kg) depending on Model. On average this equates to a weight loss from 35- 60 lbs (16-27 Kg) over a typical Lead/Acid Battery! The incredible weight savings will increase your vehicle’s performance in several key areas such as handling, allowing shorter braking distances, improved acceleration and even better gas mileage. Additionally, our Lithium-Ion battery is by far the most economical weight loss product on the market! A 30 lbs weight reduction in Carbon Fiber or Titanium would cost over $50,000 dollars compared to roughly $700-$800 dollars for our Battery.
Power: The high cranking power of the Antigravity Lithium-Ion Battery can start Motors up to 900 Horsepower easily! Additionally for even more weight loss you can go with a smaller Amp Hour Battery if you want the lightest weight possible. Power will rarely be an issue being our small batteries will easily turn over Hi-Performance Motors up to 600 Horsepower!



At Antigravity Batteries we realize our customers have different applications. So we offer different Amp Hour Capacities in the same Case Size. For example the H6 Case Size is used in the Porsche 911 Series of Cars, but is also used in some SUVs. So a higher Amp Hour Capacity Battery will be desirable in an SUV, but the Porsche owner might want to lose as much weight as possible for Track use, so we have a 24 Ah H6 Size battery that saves another 10lbs and benefits the Porsche Owner. So you can choose the option that suits your application the best. We have most models available in 24Ah, 30Ah, 40Ah and 60Ah.



Models Available in 24Ah, 30Ah, 40Ah, 60Ah

Strong cranker

Replaced an ailing lead acid battery on my 458. No more error messages and cracks like it means it. Early days but so far so good.

Best battery money can buy.
16 April 2022  | 

I bought this 60Ah battery for my Volkswagen Mk5 Polo 1.6TDI. Old 75Ah lead battery weights 17.5kg, this new one only 8.5kg. So it gave me almost 10kg of wight savings in most crucial place in car (engine bay) and I can notice slighty better car handling on the road. Battery is a beast, it have plenty of power, almost 1000cca more than old lead acid 75Ah. Also, I have to never again worry about draining a battery if I listen music for too long when car is turned off. This is purchase is expensive as f but I highly recommend it to everybody who have funds to buy it.

An excellent and necessary upgrade for my Ferrari Italia
28 July 2020  | 

I bought this battery, a 60Ah version which was delivered to the Far East within three days which is an amazing speed. The service was extremely efficient. No issues. The battery gives a strong cranking charge for my Ferrari 458. The pre-cranking voltage is usually above 13v. It holds its charge well unlike my previous ordinary lead battery which showed signs of sloppiness after only two days of not driving. With all the modern cars and their numerous complicated computers constantly draining electricity even when the car is not driven, a lead battery simply cannot hold enough charge for long enough between drives and one has to drive the car at least two to three times a week which is too much mental pressure. With the lithium battery, there is no such pressure and I can now truly enjoy driving the car without the constant worry of the battery going flat.
