Antigravity Batteries AT7B Lithium Motorcycle Battery 12V 3.5Ah with RE-START Jump-Start

The Antigravity AT7B is a lightweight, high-performance lithium motorcycle and powersport battery engineered for quick starts, extended life, and added convenience. Designed to swap directly for YT7B-sized lead-acid batteries, the AT7B delivers stable voltage and cranking power in a smaller, lighter package while adding built-in jump-start capability via the RE-START button. It’s optimized for motorcycles, scooters, shifter carts and other small powersport vehicles that demand dependable starting power without the bulk of conventional batteries.

How does the AT7B simplify getting a dead vehicle started?

The AT7B includes Antigravity’s RE-START Technology—an integrated, push-button jump-start system that eliminates the need for external jumper cables or a separate starter pack. If the battery is drained, press the RE-START button, start the vehicle, and ride away. A compatible remote RE-START accessory is also available for installations where the battery is hard to reach.

• Built-in RE-START button for immediate on-battery jump starts
• No external jump boxes or jumper clamps required
• Optional wireless remote triggers RE-START without accessing the battery
• Safe, controlled pulse to assist cranking without harming electronics

What are the performance and compatibility details?

The AT7B is a 12V, 3.5Ah lithium battery designed for high cranking power in a compact form factor. It replaces YT7B and similar size batteries and is suitable for many Ducati models, scooters, shifter carts and other small-displacement powersport machines. Its lithium chemistry gives a better power-to-weight ratio and improved cycle life versus comparable lead-acid units.

• Nominal voltage: 12V; capacity: 3.5Ah
• Direct fit replacement for YT7B-sized batteries
• Ideal for motorcycles, scooters, shifter carts, and small ATVs
• Higher energy density and lower weight than lead-acid alternatives

How durable and safe is this lithium option for powersport use?

Antigravity designs the AT7B with robust internal protection to handle vibration and typical powersport use. The battery includes safeguards against over-discharge and short conditions, and the RE-START function is engineered to deliver a controlled assist rather than an uncontrolled surge. Proper installation and following the manufacturer’s charging guidelines ensure long service life.

• Built for vibration resistance common in motorcycles and off-road vehicles
• Internal protection circuits to minimize over-discharge and fault risks
• Controlled RE-START pulses to protect vehicle electronics
• Requires compatible lithium-capable charger for optimal longevity

How does weight and size impact handling and installation?

The AT7B’s lithium construction significantly reduces weight compared with lead-acid YT7B replacements, improving handling and simplifying installation. Its compact footprint fits many OEM battery trays, and lighter mass can lower overall vehicle weight for a more responsive feel. Always confirm terminal orientation and mounting points before installation.

• Smaller, lighter than equivalent lead-acid batteries
• Fits many OEM trays that accept YT7B dimensions
• Reduced vehicle weight can improve handling and balance
• Check terminal polarity and mounting brackets prior to install

Who is this for: The Antigravity AT7B suits riders and powersport owners who want dependable starts, reduced battery weight, and the convenience of an integrated jump-start system. It’s a strong choice for Ducati riders, scooter owners, kart and shifter cart enthusiasts, and anyone replacing a YT7B-style lead-acid battery who prefers modern lithium performance and easy recoverability from a dead battery.
