Antigravity ATZ-7 Performance Lithium Motorcycle Battery - Built-In

In this review the Antigravity ATZ-7 is evaluated as a lightweight performance replacement battery aimed at riders who want reliable starting power and a built-in emergency restart feature. The single biggest reason to buy is the integrated RE-START technology, which eliminates the need for separate jump packs or jumper cables and turns a dead battery into a temporary starter solution, making it particularly attractive for off-road riders and commuters who value compact weight savings and convenience.

Key Features

• Built-In RE-START: The onboard restart button lets a rider start a vehicle after a dead battery without external gear, reducing downtime when stranded.
• Compact, Lightweight Design: Its small size and low weight save space and shave pounds compared with stock lead-acid batteries, improving handling on bikes and ATVs.
• High Cranking Power: The battery provides strong starter current, which helps crank engines harder and faster on installation.
• Remote Access Option: A remote RE-START accessory is available so users can trigger the restart without accessing the battery directly, useful for hard-to-reach batteries.
• Performance Chemistry: As a lithium powersport battery it delivers higher energy density and reduced self-discharge versus older lead-acid types.

Who It's For

The ATZ-7 is best for motorcycle, ATV and powersport riders who prioritize weight reduction, compact packaging and reliable starting power, including weekend trail riders, racers fitting light-weight components, and commuters who need dependable starts. Riders who often find themselves off-grid or out on long rides will appreciate the convenience of the built-in restart button.

It is less suitable for someone who prefers a simple, maintenance-free lead-acid swap without learning a new feature, or for vehicles that require a different physical battery size or much higher capacity than the 3.5 amp hour class implied by this model.

Pros & Cons

Pros

• Very lightweight and compact, giving measurable weight savings over stock batteries.
• Built-in RE-START feature removes the need for portable jump starters in many situations.
• Strong cranking power that starts engines quickly and reliably.
• Optional remote restart accessory adds convenience for difficult battery access.

Cons

• Battery life and long-term durability received mixed feedback, with some users reporting variable charge retention versus others who had no issues.
• Smaller amp-hour capacity than larger lead-acid batteries, so check vehicle compatibility and charging system before replacing.
