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.

Best battery ever!
have had a bt80 under the hood for 5 years and still going strong. I have 2 bt140`s in the back and about to have 3. The larger the load you put on these batteries the more they put out. Would recommend over all others.

ABSOLUTE BEAST MODE!!!
Have a big audio system in excess of 3000 watts RMS??? Still using a capacitor to supposedly "fix" light dimmage and keep up voltage only to realize they are no better than just having a voltage display??? LOOK NO FURTHER because this batt is for you!! As long as you have a HO alt, you will not have any electrical issues while using this product, and Sonic has the BEST prices anywhere!!!

Great dependability
I have had one of these in the trunk of my Dodge Avenger RT for 5 years now and I might have charged it 5 times and it’s still going strong powering a JL HD1200 and Alpine 45x4 amp. I only have 4 Gauge feeding it from the front and 1/0 going from the battery to the amps and it does great.

??????????
The SK-BT140 absolutely exceeded my expectations. From the moment I powered it on, I could tell this wasn’t some average, run-of-the-mill device. The sound quality is crisp, powerful, and surprisingly deep for its size — clean highs, solid mids, and bass that actually hits without distortion.
What really sets the SK-BT140 apart is how far above other brands it stands. It’s not even close. While competitors struggle with weak output, spotty connections, or flimsy builds, this unit delivers consistent performance, superior clarity, and rock-solid reliability every time. It outperforms comparable models by a wide margin.
Another huge advantage is that it’s a fully enclosed unit, meaning it can easily equip and integrate into virtually any setup. Whether you’re upgrading an existing system or starting fresh, it adapts seamlessly without needing complicated modifications. That kind of versatility makes it a standout choice.
The Bluetooth connection is fast and stable, pairing instantly without any hassle. The build quality feels durable and premium, not cheap or fragile. Battery life is impressive too — it keeps going without constantly needing to recharge, making it perfect for long days, gatherings, or everyday use.
If you want something that outclasses the competition, fits any configuration, and delivers serious performance, the SK-BT140 is the clear winner. Highly recommend — this one punches way above its weight.
