 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 ATZ10 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 ATZ10 Re-Start Battery is an extremely lightweight and high-power Lithium-Ion replacement for the heavy lead/acid YTZ-10 battery found in many Motorcycles including most Street and Off-Road Motorcycles and Powersport Vehicles on the market. Additionally, the new ATZ10 offers the first FULL Battery Management System (BMS) found on a Powersport Battery and includes low-voltage cut-off, over discharge, over-charge, and thermal protections with real time lithium-ion cell balancing.

The ATZ10 battery is built with Antigravity's groundbreaking RE-START Technology (built-in jump-starting) so you won’t ever get stranded with a dead battery again! This ATZ10 is a hi-power, lightweight Lithium-Ion battery that directly replaces the OEM Lead/Acid YTZ10S and other similar size batteries Rated at 360 CA, 10 Ah (Pb Eq).


  • 690/701 (YTZ10S): Exact dimensional replacement
  • 990/950/1190-1290 Adv/Rc8 (YTZ14S): This battery has a nearly identical footprint, but is about 3/4" (200mm) shorter in height. 
  • Super Duke 1290 R/GT: The battery on this page fits perfectly in width and length, but is 2" (50mm) shorter in height. This extra space can be filled with a Dynojet Powercommander V and Ignition Module nicely. The AG-AT12BS-RS battery fits perfectly in width, but is 3/4" (20mm) thinner front to back and about 3/8" (10mm) shorter from top to bottom than the battery on this page. Also perfect for extra storage of Dynojet products or anything else that may fit. 
  • RC390: Slightly shorter in height but the rubber band compensates perfectly. Side to side, front to back is identical so it fits in very well on this bike.
