Aiming at the core pain points of industrial buyers such as short battery life, poor batch consistency, weak high-current start and high later operation and maintenance cost, the battery is upgraded with corrosion-resistant alloy grid, featuring anti-aging and low gas precipitation. Its float service life reaches 3-5 years, greatly reducing after-sales replacement cost. With low internal resistance and excellent high-current discharge performance, it provides sufficient instantaneous starting power to avoid startup failure of industrial emergency equipment. Products in bulk have tiny voltage difference and strong series assembly stability, adapting to large-scale factory supporting production.
