Building a clean, capable car-audio system on a budget does not mean settling for inferior power storage — and the XS Power PS975L 12V AGM battery proves it. This mid-range PowerSport unit delivers solid cranking amperage and meaningful reserve capacity, giving your amplifiers a stable platform without the voltage sag that strangles dynamics at high volume.The PS975L's L-terminal layout simplifies cable routing in custom installs, and its sealed AGM chemistry eliminates the acid and maintenance concerns that come with flooded batteries. For a daily driver that has been upgraded with a quality subwoofer stage and a mid-level amplifier, this is a high output battery that keeps the electrical system honest without breaking the budget — and the PowerSport lineage means it is built to last through years of real-world cycling.This Listing Includes: (1) XS Power PS975L Group U1R 12V AGM Car Audio BatterySpecifications BCI Group Size Group U1R Volts 12v Max Amps 2100 CA 604 CCA 532 Ah 43 RC 72 Primary Watts NA Secondary Watts NA Polarity R Included Hardware M6 Hardware Included Warranty 2 Year — view warranty (PDF) Instructions Download instructions (PDF) Length (Inches) 7.83 Width (Inches) 5.3 Height (Inches) 6.68 Weight (lbs) 28.5 Weight (kg) 12.95 Available from JS Alternators.PROP 65 WARNING: This product can expose you to chemicals including lead and lead compounds, which are known to the State of California to cause cancer or birth defects or other reproductive harm.
