Alkaline Battery Parameters

Introduction to C-cell Alkaline Battery

The C-cell alkaline battery is a versatile, medium-sized cylindrical battery widely used in consumer electronics, professional devices, and portable tools. With a nominal voltage of 1.5 volts, C-cell batteries are larger than AA or AAA batteries but smaller than D-cell batteries, making them an ideal choice for devices that require a balance of size and energy capacity.

C-cell batteries feature alkaline chemistry, consisting of a zinc anode, a manganese dioxide cathode, and an alkaline electrolyte. This combination ensures reliable performance, high energy density, and long shelf life. Compared to older carbon-zinc batteries, alkaline C-cell batteries deliver longer operational life, better performance in moderate- to high-drain devices, and reduced leakage risk.

The cylindrical design, typically measuring 50 mm in length and 26 mm in diameter, allows these batteries to fit compactly into devices while delivering stable power. C-cell batteries are widely available and standardized, making them a convenient and dependable power source for a variety of applications.
