Fullriver DC85-12 Deep Cycle AGM Battery – 12V 85Ah Heavy Duty

The Fullriver DC85-12 is a heavy-duty 12V deep cycle AGM battery designed for applications that require reliable, sustained power delivery over long periods, making it an excellent choice for Boss Air Suspension auxiliary systems, onboard air compressors, 4WD touring builds, and camping setups with high accessory loads.

With a strong 85Ah capacity, the DC85-12 is built to handle repeated discharge and recharge cycles without loss of performance. This makes it ideal for running air compressors, air management systems, fridges, lighting, inverters, and camping accessories, particularly in vehicles where dependable auxiliary power is critical.

Ideal as an Auxiliary Battery for Air Suspension & Touring

Air suspension systems can place ongoing demand on a vehicle’s electrical system, especially during extended compressor operation or when the engine is off. The Fullriver DC85-12 excels in deep-cycle applications, making it well suited as:

• An auxiliary battery supporting Boss Air Suspension compressors

• A secondary battery in dual-battery touring setups

• A dedicated power source for camping and off-grid accessories

Its stable voltage output helps ensure consistent compressor performance and reliable accessory operation during extended use.

AGM Construction Built for Harsh Conditions

The DC85-12 uses Absorbent Glass Mat (AGM) technology, meaning it is fully sealed, spill-proof, and maintenance-free. This makes it suitable for installation in engine bays, trays, canopies, and enclosed battery compartments.

Designed with full frame plates, high-purity lead calcium alloy grids, and low-resistance glass-mat separators, this battery offers excellent durability, fast recharge acceptance, and long cycle life—key advantages for off-road, touring, and demanding environments
