 NEW RE-START Series: The first batteries with built-in jump-starting!

Never again worry about getting stranded with a dead battery! Antigravity Batteries introduces the groundbreaking “RE-START (RS)” line of batteries – the first batteries with built-in jump starting! The revolutionary ATZ-7 RE-START Battery intelligently monitors its status, and just before going completely dead puts itself to sleep with just enough energy to get your vehicle started again. This compact, lightweight Lithium-Ion battery directly replaces the OEM YTZ7S and YTZ5 bateries. 90% of off-road bikes use this size as well as some street bikes. 


  • For replacement of all OEM Lead/Acid Batteries of the same size
  • Capable of everyday street use in bikes up to 450cc 
  • Great for Enduro and MX Electric start bikes up to 450cc
  • Race and Track Day use in 4-Cylinder 600cc sport bikes

  • RE-START TECHNOLOGY: The RE-START Battery intelligently monitor its status; if it senses over-discharge it will put itself into a sleep mode, yet saves enough energy to allow you to RE-START your vehicle. Simply press the RE-START button on battery. (A Remote RE-START Button will soon be Available so you can activate the RE-START feature without accessing battery.)
  • LONGER LIFE: Up to twice the lifecycle of lead/acid, and other Lithium batteries due to full Battery Management system.
  • HI POWER: Up to 2 Times the Cranking Amps of similar sized lead/acid batteries. Better Starting and higher voltage at start-up.
  • ULTRA LIGHTWEIGHT: Up to 70% lighter than equivalent lead/acid battery. Up to 15 lbs in bikes or 40 pounds in some Race Cars. Carbon Fiber costs thousands to lose a pound of weight; with our LiFePO4 battery a few hundred dollars will lose roughly 8-15 pounds and offers better starting and handling!
  • NEW 4 Terminal Design allows easy installation in any vehicle. Fits right or left hand Negative or Positive connections. No more looking for the correct Terminal locations in certain bikes.
  • LOW SELF-DISCHARGE: The RE-START Batteries do not self-discharge like Lead/Acid Batteries. They can hold a charge up to a year provided there are no “Parasitic Drains” (accessories that draw power when bike is off, i.e. alarms, ECUs, GPS, heated grips, and other accessories the vehicle might have).
  • DURABILITY: Our lithium batteries are shock and vibration resistant making them perfect for Racing, and other applications requiring a durable battery.
  • MOUNTING: You can mount our battery in any orientation, there are no liquids to spill or drain out.
  • ENVIRONMENTALLY SAFER BATTERY: No Acid or Heavy Metals such as Lead, Cadmium, or Mercury.
