Lithium Battery 900CCA 5.18lbs

The ANTIGRAVITY BATTERIES Lithium Battery 900CCA (Model AG-ATX20-HD) is designed for automotive enthusiasts seeking extreme weight savings without compromising cold-cranking power. This battery is ideal for performance builds, classic car restorations, and weight-critical applications, replacing traditional lead-acid batteries while ensuring reliable starts in demanding conditions.

Weighing just 5.93 lbs, the AG-ATX20-HD provides 900 CCA, making it capable of starting engines even in sub-zero temperatures. The lithium chemistry offers advantages over lead-acid batteries, including longer cycle life, better charge acceptance, and improved thermal stability, which prevents voltage sag during high-demand situations. Its compact dimensions of 10.4 x 9.4 x 11.5 inches allow it to fit into tight engine compartments without modification.

This battery is particularly beneficial for enthusiasts upgrading vintage platforms, drift builds, and road-racing vehicles, as the significant weight reduction—typically 35+ lbs lighter than OEM equivalents—enhances acceleration, braking response, and overall chassis dynamics. The internal management systems ensure cell protection from overcharging and deep discharging, extending the service life well beyond that of conventional batteries.
