Infinite AGM Power Cell Battery

The DS18 Infinite AGM Power Cell Battery line represents a high-performance electrical solution engineered specifically to support the rigorous current demands of high-output car audio systems. Built using advanced Absorbed Glass Mat (AGM) technology, these premium batteries suspend electrolyte fluid inside high-purity fiberglass mats to optimize energy transfer. This completely sealed, maintenance-free, and non-spillable design gives installers the flexibility to mount the power cell in various orientations within tight cabin or trunk cavities while offering maximum safety and superior resistance to severe vehicle vibrations.

Designed to eliminate devastating voltage drops, dimming headlights, and amplifier clipping during intense bass peaks, the Infinite AGM platform features an ultra-low internal resistance profile that facilitates exceptionally fast discharge rates and rapid charging recovery. The internal lead-calcium grids are tightly packed and housed within a rugged, heat-resistant ABS plastic casing, maximizing cell plate compression to extend the battery's deep-cycle lifespan. Serving as a rock-solid electrical foundation, this power cell delivers clean, consistent burst current to keep multi-amplifier builds performing at their full musical potential with uncompromised dynamic headroom.
