Show original supplier description

The Antigravity AG-35-RS is a cutting-edge Group 35/Q85 lithium-ion automotive battery designed to replace your lead-acid battery with enhanced performance and innovative features. Its standout technology is the exclusive RE-START system, which provides built-in wireless jump-starting. If the battery becomes discharged, a simple press of the included keyfob remote allows you to start your vehicle without needing external jump-starting equipment or roadside assistance, even without opening the hood. Constructed with Lifepo4 lithium chemistry and a complete Battery Management System (BMS), this battery prioritizes safety and longevity. The BMS includes circuitry for over-discharge and over-charge protection, short-circuit protection, cell balancing, and thermal management, aiming for a life cycle of 7-9 years. The AG-35-RS boasts 40 amp-hours and a high power output of 1500 cranking amps, capable of starting engines up to 600 horsepower. Designed as an exact drop-in replacement, the battery features the standard Group 35/Q85 OEM automotive case size (9 x 6.85 x 8.6 inches), ensuring direct compatibility with many performance and passenger cars and trucks without requiring modifications. It is important to note that only a Lithium Lifepo4 charger should be used when charging this battery.
