Replaces: YT12-BS, YT12B-BS, YT12B-4, YT14-BS, YT14B-BS, YT14B-4

The NEW Antigravity AT12-BS-HD battery is built with Antigravity's groundbreaking RESTART Technology (built-in jump-starting) so you won’t ever get stranded with a dead battery again! This is the HEAVY DUTY version of our standard duty AT12-BS-RS and offers more capacity/cranking power for those who need it. The AT12-BS-HD is a hi-power, lightweight Lithium-Ion battery that directly replaces the OEM Lead/Acid YT12-BS, YT12B-BS, YT12B-4, YT14-BS, YT14B-BS, and YT14B-4.

The revolutionary AT12-BS-HD 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. Simply press the RE-START button located on the battery, start your vehicle and drive away… No more dead battery emergencies or being stranded!

The new AT12-BS-HD is an extremely lightweight and high-power Lithium-Ion replacement battery for the heavy lead/acid YT12-BS battery found in many Motorcycles and Powersport Vehicles. The AT12-BS-HD offers the first FULL Battery Management System (BMS) found on a Powersport or Yamaha motorcycle battery and includes low-voltage cut-off, over discharge, over-charge, and thermal protections with real time lithium-ion cell balancing. 

  • For replacement of all OEM Lead/Acid Batteries of same size.
  • Excellent for every day use in bikes up to 1500cc.
  • Excellent for Modified motors, Adventure Bikes and applications where extreme power and larger Amp Hour capacity are needed.
  • Great for use in Race Cars up to 600 Horsepower.
  • Excellent for use in Race Cars of all types up to 500 Horsepower.
  • Not for use with Personal Water Craft (PWC).
  • Not for deep cycle application. Meant for starting applications only.


  • 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.
  • FULL Battery Management System (BMS) including Over-Discharge, Over-Charge*, Thermal Protections and Cell Balancing.
  • 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.
  • 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”. Bikes with accessories that draw power when bike is off like alarms, ECUs, GPS, heated grips, and other accessories should be maintained with a charger.
  • 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.


Per Antigravity Inc.:*Over-Charge protection will not protect from a faulty/old Voltage Regulator spiking Hi-Voltages to Battery. If you have a Pre-1990s Motorcycle replace your voltage regulator; it is over 25 year old and most likely broken by now.
