12V 20Ah AGM Deep Cycle Battery

The Fullriver HC20 is a 12V 20Ah deep-cycle battery engineered with AGM (Absorbent Glass Mat) technology, offering a sealed, maintenance-free design that minimizes spill risk and provides thousands of useful cycles. Constructed with high-compression cells and a durable ABS plastic casing rated for flame resistance (UL94-HB), this battery is built to withstand impact and vibration. Its pure lead cells and thin plaque technology ensure reliable energy delivery even under high demand. The HC20 features M5 insert terminals and has dimensions of 181mm x 77mm x 167mm. Fullriver batteries are manufactured under strict quality controls, holding certifications such as ISO9001, ISO14001, ISO18001, UL, CE, and TEN. The HC20 offers a long useful life, typically exceeding that of moist cell counterparts due to its pure virgin lead construction and maintenance-free design. It can be mounted vertically or horizontally, offering installation flexibility. The product comes with a 2-year manufacturer's warranty covering manufacturing defects like damaged cells or internal short-circuits, but excludes damage from misuse such as prolonged overcharging, unsuitable chargers, or a faulty alternator.
