Shuriken SK-BT120 12-Volt High Performance AGM Power Cell Battery for Systems Up To 2400-Watts

I had this exact battery for 3.5 years then I needed to buy this one. This battery is reliable and would recommend to any audiophile that needs a lot of power.

The perfect battery for your audio car

Don’t waste your time on this, battery died n doesn’t charge . I’ve contacted the owner and says they don’t sell on Amazon and won’t warranty it. Garbage company as a whole . Spent over 1500$ in their battery’s in a year.

Excelente precio, llegaron en un dia xq el vendedor esta en florida. Sim embargo una de ellas llego con un pequeño golpe en una esquina y tuve que reparar con pega epoxica el borne que presentaba una pequeña fuga.

As with all flooded, lead acid batteries, you wont get full amp hour rating, may be half if your are lucky. Lead acid batteries are old technology, the only lead type battery, if I was going to buy a lead acid, would be the Chrystal type battery and for sure the LiFePO4 battery.

After a recent stereo upgrade in my 2009 Toyota Tundra Crewmax, I bought this battery as part of a BIG 3 upgrade kit. In addition to the battery I upgraded the wiring from the alternator to the battery, the ground wiring to the engine block and chassis. It was really easy with a kit I purchased online just for my Tundra. The wiring and this battery fixed my "dimming" issue when my subs would hit low notes. As an added bonus, I can run off the battery for nearly 3 hours (stereo blasting) without having to turn on my truck. My stock battery would only last about 45 minutes.I had spent $200 on a capacitor after being told by an "major" online audio provider that is what I needed. Fortunately they took the cap back and I applied the money to my big 3 upgrade and this battery. Could not be happier.Stereo System: Pioneer NAV Z110BT, Alpine PDX-4.150 & PDX-1.1000, Image Dynamics XS65 Components Speakers Front and Rear Doors, 2 Image Dynamics IDQ12V3 subwoofers in a port tuned box. The battery made the notes sound clearer and the system is UNREAL volume and clarity.A few of the items in my system. I purchased the Amps through Amazon, saved $400 over the "other guys". I love me some Amazon!!Alpine PDX-4.150 - Amplifier - 4-channelAlpine PDX-1.1000 - Amplifier - 1-channelPioneer AVIC-Z110BT 7-Inch Flagship In-Dash Navigation A/V Receiver with DVD Playback and Bluetooth

A little bit of real world information: Depth of Discharge for an AGM is about 50%-70%, where it's 80%-100% on Lithium Iron Phosphate batteries (Lipo4). Lipo4's last up to 10x longer. And they are half the weight of lead acid chemistry. I just bought a 100Ah Lipo4 for nearly the same cost, mind you it doesn't have cold temp cut off on the BMS but that didn't matter to me since it's a battery for my trolling motor. It weighs 23 lbs.
