C Rechargeable 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. Rechargeable C batteries have a slightly different chemical composition from standard C batteries, allowing their energy levels to be replenished and extending the shelf life of the battery.

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.

Due to their energy density, 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 rechargeable 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 non-rechargeable C batteries, please visit our range here.

As the name suggests, rechargeable C batteries can be recharged hundreds of times, making them a truly sustainable choice. Some C size rechargeable batteries are built into the device that they power, such as smartphones, laptops and other portable devices, while removable models require a separate adapter for the charging process.

There are various different types of rechargeable C batteries available, including:

  • NiMH (nickel-metal hydride)
  • NiCd (nickel-cadmium)
  • Li-ion (lithium ion)
