Carbon Battery Parameters

Introduction to AA Batteries (R14, C Size)

The R14 battery, commonly referred to as C size, is a medium-sized cylindrical battery widely used in devices requiring moderate to high energy output. With a nominal voltage of 1.5 volts, R14 batteries provide reliable power for a variety of household, professional, and portable devices. These batteries are larger than AA batteries (R6) but smaller than D batteries, making them ideal for devices that need sustained energy without excessive bulk.

R14 batteries typically use alkaline chemistry, consisting of a zinc anode, manganese dioxide cathode, and alkaline electrolyte, which ensures long shelf life, stable voltage output, and high energy density. They can also be found in carbon-zinc chemistry for lower-cost applications. Standardized dimensions—approximately 50 mm in diameter and 50 mm in height—allow R14 batteries to fit seamlessly into compatible devices worldwide.

C-size R14 batteries are widely available and are considered a reliable, long-lasting, and cost-effective power solution. Their moderate size and capacity make them ideal for medium-drain devices, bridging the gap between compact AA batteries and high-capacity D batteries.
