A D battery (D cell or IEC R20) is a standardized size of a dry cell. … D cells are typically used in high current drain applications, such as in large flashlights, radio receivers, and transmitters, and other devices that require an extended running time. A D cell may be either rechargeable or non-rechargeable.
