Antigravity Batteries ATX12-HD 8Ah Heavy-Duty Lithium Powersport Battery — Built-in RE-START Jump Start, OEM Fit

The Antigravity ATX12-HD is an 8Ah heavy-duty lithium powersport battery with built-in RE-START jump-start technology, a robust battery management system, and OEM-fit terminals for a drop-in replacement in ATVs, UTVs, scooters, lawn mowers, generators and many motorcycles.

The ATX12-HD blends high-performance lithium cells with an integrated restart mechanism and advanced protection electronics to deliver reliable starting power and fast recharge times. Designed for riders and powersport owners who need dependable starts in cold weather, race days, off-grid use or everyday maintenance equipment, this pack emphasizes safety, usable cranking amps and convenient installation without modifying wiring harnesses.

How does the built-in RE-START jump-start feature work?

The battery includes a user-activated RE-START button that temporarily boosts output to start a vehicle with a depleted charge—no external jump pack or donor vehicle required. A remote trigger accessory is available for hard-to-reach battery locations so you can operate the feature from the cockpit or frame area.

• On-board push-button activation for immediate cranking assistance
• Remote RE-START accessory option for mounted or enclosed battery boxes
• Eliminates need for jumper cables or separate starter packs

What safety protections does the ATX12-HD include?

An integrated Battery Management System (BMS) monitors cell balance and protects against overcharge, over-discharge and extreme temperatures. The BMS extends service life and prevents conditions that can damage lithium cells, providing dependable operation across varied environments.

• Cell balancing for even charge distribution and longevity
• Over-charge and over-discharge cutoffs to protect the pack
• Temperature-sensitive safeguards for hot or cold operating conditions

Will this battery fit my vehicle and how easy is installation?

The ATX12-HD uses true OEM case dimensions and a quad-4 terminal layout for flexible, accurate fitment in many motorcycles, ATVs, UTVs and small engines. Terminals are square, like OEM types, and the pack can be rotated 180° to swap polarity orientation without adapters.

• True OEM case sizing for drop-in replacement compatibility
• Quad 4 terminal design supports multiple harness layouts
• Turn the battery 180° to change polarity alignment when needed

How does the charging performance compare to lead-acid batteries?

The ATX12-HD charges far more quickly than lead-acid equivalents, allowing for shorter recharge cycles and more ready-to-go starts. The internal chemistry and design enable rapid acceptance of charge so you can get back to riding or operating equipment sooner after draining.

• Faster charge acceptance for reduced downtime between starts
• Higher usable cranking amps and amp-hours versus same-size competitors
• Engineered for repeated starts and cold-weather reliability

Who this battery is for: The Antigravity ATX12-HD is suited to motorcycle riders, ATV/UTV and quad owners, landscapers using mowers, scooter operators, portable generator users and racing teams who demand a compact, high-output lithium battery with on-board restart capability. If you want a drop-in lithium upgrade with fast charging, strong cold starts and built-in start-assist—without rewiring—this battery is a practical choice.
