C Batteries

C batteries are known as ’dry cell’ batteries, due to the fact that they were created to operate in applications or products with minimal internal moisture. C batteries are larger than other standard dry cell batteries, such as AA and AAA, and as such they offer a reliability and longevity you may not get from other batteries in the same circumstances.

C batteries are built to the standard size of 50mm/1.97inches in length x 26.2mm/1.03inches in diameter.

C batteries are also known as R14s, following their designation by the International Electrotechnical Commission (IEC).

What are C batteries used for?

Typically for high drain applications like torches, digital cameras or security lighting, where you require a battery that will last a long time, the C battery can be installed to suit those needs. Coming in a variety of brands and capacities, always check what applications you will be using them for. For help choosing the type of battery best suited to your needs, please see our C batteries guide.

Standard C batteries are ideal for portable devices which consume mid-high levels of power. They are widely used in:

  • Torches
  • Cameras
  • Radios
  • Intruder alarms
  • Musical instruments
  • Walkie-talkies
  • Toys

What types of C batteries are there?

C batteries are available in standard (non-rechargeable) and rechargeable types, each with their own strengths and weaknesses. For more information on our rechargeable C batteries, please visit our range here.

Standard C batteries are available in two chemical types:

  • Alkaline – these are the most widely used types of batteries due to their energy density and long shelf life and are commonly found in everyday items.
  • Lithium – Also noted for their long performance lives, lithium C batteries are distinct from the rechargeable lithium-ion V batteries typically found in laptops or smartphones.
