Trojan Battery now offers a 4-year warranty on its TransPower ST1000 starting AGM battery for trucks (and buses).

The Trojan TransPower ST1000 is a sealed, maintenance-free AGM 31 starting battery. Several design features contribute to high cranking power and longevity.

The ST 1000 features a high-density paste formulation that’s said to optimize density, porosity and surface area, achieving the right balance of power and durability.  

Its heavy-duty plate design is thicker than standard starting battery plates, the company says. Combined with high-density paste and a gravity-cast, thick-wire grid design, the plate construction delivers nearly double the battery life of a standard flooded starting battery, Trojan says. The plate design also tolerates extreme weather conditions.

The battery is packaged in a thick-walled, durable polypropylene case that’s rigid to keep the battery’s internal components compressed. This protects the plates from damage caused by shock and vibration, the company says. The case is also resilient against engine oil, gasoline, and road chemicals like salt and magnesium chloride.
