RE-START TECHNOLOGY

BUILT-IN JUMP-STARTING

Never stranded again… 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 the battery would put itself to sleep before being drained dead, yet save just enough energy to start your vehicle 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.

FULL BATTERY MANAGEMENT

BUILT-IN BMS FOR SAFETY AND LONG LIFE

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.

EXACT DROP-IN FITMENT

EXACT FIT FOR MOST VEHICLES

The Antigravity Batteries RE-START Automotive Batteries come in EXACT FIT OEM sizes for most all Performance and Passenger Cars/Trucks. We are the First Lithium-Ion Battery company to offer the most popular BCI Sizes of H5/Group 47, H6/Group 48, H7/Group 94R, Group 35 and others. These are standard sizes in most all European and American Cars and Trucks.  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! (Please check our Car Battery Fitment and Car Battery Installation pages for details).

PERFORMANCE BENEFITS

Weight: The ultralight Antigravity RE-START Batteries weigh from 8.5 lbs to 16.5 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!

AMP HOUR / CAPACITY OPTIONS

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 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.

FEATURES & BENEFITS

  ULTRA LIGHTWEIGHT: The Antigravity RE-START Battery can be as much as 70% lighter than the Lead/Acid equivalent. This equates to roughly 25-55 lbs of instant weight-loss just by changing out the battery! That makes the Antigravity Lithium-Ion Battery the most cost-effective weight-loss product hands-down, while offering better starting, handling and braking! A real performance value!

  LOW SELF-DISCHARGE: The RE-START Battery does not self-discharge like Lead/Acid Batteries. It offers a longer storage time provided there are not excessive Parasitic Drains on the battery.

My lab loved it too much, too fast…
Color: blue, Color: blue
It arrived an hour ago and my lab has it in pieces within minutes. It kept him busy for a bit though! I’ll give it to him again but I’ll have to sit with him, for sure. No squeak? I guess he just didn’t get to that part of the toy. It felt sturdy but ultimately didn’t pass the test.

Colorful, Sturdy & Great Value
Color: Large Set of 4
Purchased for our two puppies when they were 2 months old and weighed about 14 pounds so theses balls were a little big for them to hold in their mouths but that didn't stop them from trying. While they did like these balls they much preferred softer soccer balls, the later of which did not hold up well at all. I had hoped they would play with these balls more when they were older but that hasn't happened 5 months later. I guess it's no fun if you can't tear the toy apart. Colors are very bright and they do enjoy chasing after them as long as I am the one rolling them across the room for them. Maybe when they progress to batting things with their paws they will start to do this for themselves.
