We have partnered with blue-chip manufacturers to jointly develop our products. In addition to maintenance-free batteries with a long service life, the range also includes basic specification batteries designed for cost-effectiveness and durability, with a robust structure that suppresses shock and vibration. The maintenance-free battery uses a special calcium alloy and high-purity lead, which prevents a reduction in service life due to its resistance to heat and corrosion in high-temperature environments. The double top cover reduces electrolyte depletion and the use of materials with excellent durability and electrical properties for the electroplate ensures a long service life. The low-resistance separator prevents shorts between the electrode plates and ensures stable starting in all environments.
