Introduction
The C-size alkaline battery (LR14) is a medium-high capacity primary cell engineered for devices requiring sustained power and moderate-to-high current output. Positioned between AA/AAA and D-size cells, it offers larger energy storage than small cells while maintaining compact form factor for versatile use.
Manufactured with high-purity manganese dioxide, zinc alloy anode, and optimized alkaline electrolyte, it delivers stable 1.5V output, low internal resistance, and long-lasting discharge. The LR14 is ideal for portable radios, mid-sized flashlights, toys, medical instruments, and other mid-power devices.
With enhanced leak resistance, temperature tolerance, and over 5-year shelf life, it ensures safe, reliable, and maintenance-free operation. Compared with smaller AA/AAA or larger D cells, the C-size battery offers the best balance between energy capacity, current output, and device compatibility, making it the optimal choice for medium-drain applications.
