Lithium Battery Group 48/H6 1500CCA 12 Volt

The Lithium Battery Group 48/H6 1500CCA 12 Volt by ANTIGRAVITY BATTERIES represents a generational leap in automotive electrical systems for serious enthusiasts and professional mechanics alike. This lightweight lithium alternative to traditional lead-acid batteries delivers the cranking power you demand without the excess weight that compromises handling dynamics and acceleration. Whether you're building a high-performance street car, a track-focused machine, or restoring a classic with modern reliability, this battery eliminates the parasitic mass penalty that plagues conventional H6-group batteries.

At 1500 cold cranking amps (CCA), the Lithium Battery Group 48/H6 delivers proven starting authority in any climate while weighing just 16 pounds—roughly 60% lighter than an equivalent flooded-cell H6 battery. Lithium chemistry provides superior voltage stability under load, faster charge acceptance, and dramatically extended cycle life compared to traditional batteries. The compact 8 x 8 x 11.1-inch footprint maintains factory H6-group form factor compatibility, ensuring direct bolt-in installation without fabrication. ANTIGRAVITY's engineering emphasizes thermal management and integrated battery management systems (BMS) to maximize longevity and prevent premature discharge during vehicle storage.

Performance builders, track day drivers, and weight-conscious restorers benefit most from this upgrade, particularly in platforms where every pound impacts suspension geometry, braking balance, and acceleration. The reduced unsprung and rotational mass translates to measurable improvements in chassis responsiveness and fuel economy on street applications. Installation is straightforward for any vehicle originally equipped with an H6 battery group; verify terminal orientation and secure the battery to your existing mounting tray using factory hardware. This lithium battery is ideal for vehicles with alternator outputs between 60–200 amps and suits both stock and modified electrical systems that demand reliable cold-start performance without compromise.
