Antigravity G35/370Z/G37/370Z/Q50/Q60 Q85/Group 35 Lightweight Lithium Car Battery w/Re-Start

The AntiGravity Group 35 Lithium Battery is the ultimate direct-replacement upgrade for VQ-platform cars including the G35, 350Z, G37, 370Z, Q50, and Q60. Weighing only 14.2 lbs compared to the ~40 lbs stock lead-acid battery, it bolts straight into the factory tray with no modifications, adapters, or custom brackets required. This means it’s the easiest and cleanest way to shed almost 25 lbs from the highest point in the engine bay, instantly improving handling balance, steering response, and overall performance.

Beyond the weight savings, this battery delivers superior starting power and consistency thanks to modern lithium LiFePO₄ technology. It’s designed to last 10+ years, far outliving traditional lead-acid units, and features AntiGravity’s built-in RE-START technology, allowing you to safely restart the car if the battery is ever over-drawn. With its ultra-low self-discharge rate, it stays ready to go even after long periods of sitting, making it perfect for both street and track cars.
