Description


Shuriken AGM Power Cell Battery

The Metra Shuriken AGM Power Cell Battery line represents a premium, high-performance energy storage solution engineered specifically to meet the punishing demands of modern mobile electronics and high-output car audio systems. Built using advanced Absorbed Glass Mat (AGM) technology, these rechargeable reserve power cells suspend electrolyte fluid within tightly packed fiberglass mat separators. This completely sealed, maintenance-free, and leak-proof architecture yields an exceptional spill-free design, giving installers the total flexibility to mount the battery in any orientation or position within tight custom enclosures, cabin spaces, or trunk cavities.

Engineered to eliminate devastating voltage drops, dimming headlights, and amplifier clipping during sudden bass peaks, the Shuriken platform features closely packed pure virgin lead plates that deliver a super-low internal resistance (ESR) profile. This construction facilitates rapid, high-current power transfer and efficient deep-cycle recharging capability, enabling the cells to be fully discharged and cycled hundreds of times without structural degradation. Housed within a rugged, reinforced case built to withstand extreme automotive heat and violent vehicle vibrations, these robust power cells provide the consistent current reserves and winning edge required for serious SPL competitions and demanding street demo setups alike.

great price

The battery is small and does not take up alot of space. The battery stated it can handle up to 700 watts. My system is 600 watts. Haven't had it long enough to rate the durability of it. My lights do dim a little bit but not like before.
