The HC225-12HR is an AGM (Absorbent Glass Mat) battery which is part of the Fullriver HC Battery Series (High-cranking / High-Cycling).

This battery has the capability to draw benefits from both ends of the spectrum. It is a spill-proof AGM battery which provides even more cranking power than the conventional starting battery but also combines this feature with true deep-cycling capabilities.

The HC225-12HR has a high-purity lead AGM construction which  accepts rapid re-charging, providing more usable power than traditional deep-cycle batteries.

The Fullriver HC Series are usually recognizable by their bright yellow casings but can also be ordered with powder coated black metal jacket to further improve impact resistance and durability in off-road applications including four-wheel driving and Motorsport.
