Alkaline Battery Parameters

Introduction to D-cell Alkaline Battery

The D-cell alkaline battery is a high-capacity, cylindrical battery widely used in devices requiring long-lasting and reliable power. With a nominal voltage of 1.5 volts, the D-cell battery is larger than AA, AAA, and C-cell batteries, providing extended energy output suitable for high-drain devices and long-term use.

D-cell batteries utilize alkaline chemistry, comprising a zinc anode, manganese dioxide cathode, and alkaline electrolyte. This combination allows stable voltage delivery, high energy density, and a long shelf life. Compared to traditional carbon-zinc batteries, alkaline D-cells offer longer operational life, better performance under heavy loads, and reduced leakage risk.

Typically measuring 61.5 mm in length and 34.2 mm in diameter, D-cell batteries are ideal for medium to large devices such as flashlights, portable fans, and emergency lighting systems. They are widely available, standardized, and convenient for both household and professional applications.
