Introduction
The D-size alkaline battery (LR20) is a high-capacity, high-drain primary cell engineered for applications requiring long-lasting power and strong current output. Compared with smaller alkaline batteries, the LR20 delivers significantly higher energy storage and superior discharge endurance, making it ideal for industrial, professional, and heavy-duty devices.
Built with high-density manganese dioxide, reinforced zinc alloy anode, and an advanced alkaline electrolyte system, it ensures stable 1.5V voltage, low internal resistance, and excellent performance under continuous or pulse load.
The D-size cell provides extended operational life, enhanced leak-proof reliability, and outstanding temperature stability, suitable for flashlights, radios, emergency equipment, portable lighting, and large medical or industrial instruments.
Compliant with ROHS, CE, and MSDS standards, this battery combines durability, safety, and long-term energy consistency, making it the preferred choice for high-power and long-duration applications where smaller cells cannot meet performance demands.
