Stark Energy AGM batteries are built with the harshness of the Canadian climate in mind; the Stark SRK-125AGM continues to operate at -40C. They are spill proof and easy to transport. Their advanced absorbed glass-matt design (AGM) ensures that the electrolyte stays close to the battery plates, and recombines gases during charging, allowing Starks to be sealed, maintenance free and spill-proof construction.

The key benefit to the Starks AGM batteries over competitive brands is the improved cycle life. Stark's offer: 1. Cycle life to 100% DOD: Stark 25% Better (>300) 2. Cycle life to 50% DOD: Stark is 50% Better (>900) Starks offer better life and longer trouble free operation than their competitors. Just compare the specification sheets - if they don't talk cycle life, they are a light duty battery!
