RE-START Series: FIRST Batteries with Built-In Jump-Starting!

OEM Size Lithium Battery (Direct Replacement)

Never stranded again… Antigravity Batteries introduces the Patent Pending and incredible “RE-START (RS)” line of batteries – the first batteries with built-in jump starting!

The NEW for 2025 ATZ-10-HD (Heavy Duty) RE-START Battery takes our ultra-popular ATZ10, one of the most popular sizes in ADV bikes and other Motorcycles, and replaces the 6.1 Amp Hour Battery with a (50% larger) MASSIVE 9 Amp Hour Lithium Battery pack making it the Highest Capacity and Most Powerful “10” size battery on the market. So you ADV Riders who need the most capacity possible now have a battery with the largest battery capacity possible in this size Case!

The RE-START line of Batteries 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!

If your battery is hard to reach, we offer our “RE-START REMOTE” accessory to activate the built-in Jump Starting of our batteries without having to remove your seat or side panels. Simply plug in the RE-START REMOTE into your existing SAE Charging Pigtail and turn on/ off to activate the RE-START feature and start the vehicle. No need to remove your seat or access the battery.

The ATZ-10-HD 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, ADV and Off-Road Motorcycles and Powersport Vehicles. Additionally, the ATZ10-HD-RS offers the first FULL Battery Management System (BMS) found on a Powersport Battery and includes low-voltage cut-off, over-discharge protections, over-charge protections, and thermal protections with real-time lithium-ion cell balancing.

If you want to also track your battery status via Bluetooth, you can use our Battery Tracker.

FEATURES

Most Advanced Lithium Battery on the market.
World's First Battery with Built-in Jump Starting, using our RE-START Technology.
World's First Powersport Battery with a FULL Battery Management system (BMS) including Over-Discharge, Over-Charge*, Thermal Protections and Cell Balancing.

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.

(*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.)

For replacement of all OEM Lead/Acid Batteries of same size.
Excellent for every day use in bikes up to 1400cc.
