Trojan Battery Co., a manufacturer of deep-cycle technology batteries, has announced that a four-year warranty is now offered for its TransPower ST1000 starting AGM battery for commercial transportation markets. The increased warranty coverage provides customers the lowest total cost of ownership available over the life of the battery, the company said.
The Trojan TransPower ST1000 is a sealed, maintenance-free AGM 31 starting battery engineered for rugged durability, outstanding cranking power and long life. It features an advanced paste formulation, heavy-duty plate design and rugged polypropylene case, according to the company.
Battery performance and longevity are influenced by the physical structure of the active material, the maker said. Delivering high cranking power requires a paste formulation with high porosity characteristics and maximum surface area. Longer battery life requires higher density paste characteristics. The Trojan TransPower ST 1000 features a high-density paste formulation, which optimizes density, porosity and surface area achieving the right balance of power and longevity, the company, noted.
The new battery is constructed using a heavy-duty plate design that is thicker than standard starting battery plates. Engineered with a combination of 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. The heavy-duty plates are encased in a glass mat envelope, minimizing the risk of internal shorts. Additionally, the plate design tolerates extreme weather conditions through a wide range of operating temperatures, according to the company.
Within the plate design is a grid network constructed with thick wires, which are highly resistant to corrosion, which is a typical failure mode in batteries. The wires are arranged in a sunburst array architecture that ensures peak performance by guiding the battery’s power to a focal point of charge resulting in 1,000 cold cranking amps, the company said. The overall grid framework is manufactured using a gravity cast process to produce a grid with uniform properties throughout the framework, ensuring maximum recharge efficiency and long life, according to Trojan.
The battery is packaged in a thick-walled, durable polypropylene case that is rigid to keep the internal components of the battery compressed. This case structure effectively protects the plates from damage that is caused by shock and vibration. The polypropylene case is resilient against engine oil, gasoline and other road chemicals including salts and magnesium chloride, the maker added.
