What is a C battery?

This battery, also called a C-size battery or an R14 battery, is a dry-cell battery often utilized in toys, flashlights, and musical instruments that don't need much power.

Dry cell batteries of size C are one of the most common sizes. 

The most common sizes of dry cell batteries are AA and AAA, but because they are smaller, they don't last as long as size C batteries.

C size battery standard size: 50 mm/1.97 in length and 26.2 mm/1.03 in diameter.

Various Types of C Batteries

Regarding availability, the two most common C batteries are the standard (non-rechargeable) variety and the rechargeable variety. Before deciding which C battery type is best for your needs, you should familiarize yourself with the two options.

These two options are important in making you have a battery that easily serves your intended purpose.

Non-Rechargeable C Batteries

For devices that require moderate to heavy power, non-rechargeable C batteries are an excellent choice.
C-type batteries are manufactured to a standard size to provide compatibility with a various wide variety of devices.

Rechargeable C Batteries

This type of C battery may be recharged countless times, rendering them a long-term sustainable option. Some of these batteries are connected to the power device, while removable ones need a charging adapter.

Rechargeable C batteries come in a wide variety of types, some of which are:

  • NiMH (nickel-metal hydride)
  • Li-ion (lithium iron)
  • C Battery Voltages
  • NiCd (nickel-cadmium)


Nominal Voltages available for Non-Rechargeable Batteries

There is a clear distinction between different types of batteries based on their voltage. A battery's "nominal voltage," or maximum capacity under ideal conditions, is marked on its label. However, voltage discharge fluctuates depending on operational needs.

1.5v C Batteries

The 1.5-volt C battery is a standard, non-rechargeable 1.5V C battery in many household appliances such as clocks and radios.

3V C Battery

There aren't many uses for C batteries with a nominal cell voltage of 3V daily. They are used as professional batteries in many industries and for many professional purposes.
Most of the time, it's used in Smart gas meters, mining applications, Petrochemical facilities, and gas and leak detectors.

3.6V C Battery

The higher voltage of these batteries makes them suitable for commercial and industrial use. The typical material for these is lithium. These are necessary components of the next generation of microelectronics. Keeping the battery permanently wired into the system helps to ensure the application will continue to work well throughout a broad temperature range.

Typical Applications:

  • Industrial Applications
  • Buoys
  • Professional Electronics
  • Measuring Equipment
  • Automatic meter and professional meter readers


C Batteries Buying Guide

The Most Important Features to Consider


When looking for fresh C batteries, consider their capacity and discharge rate. C battery capacity is the milliamps it can supply for one hour (mAh). Higher mAh means longer battery life. C batteries barely hold 8,000 mAh.

Discharge rate must be considered together with total capacity because a high-capacity battery is useless if it empties quickly. Use a battery tester if you're wondering about your batteries' efficiency.

Battery Type


There are only two types of C batteries available: alkaline and rechargeable. Regarding batteries, alkaline is the most popular and affordable option. Unfortunately, once they've been released, they're useless and must be thrown away. Flashlights and emergency kits benefit most from using non-rechargeable batteries.

Rechargeable batteries have an inherently extended lifespan since they can be recharged repeatedly after use. Rechargeable batteries come in many forms, with lithium, nickel metal hydride, nickel cadmium, and other metals all being used.

NiMH rechargeable batteries are the best option for toys and electronics you plan to keep around for a while.

Shelf Life

When choosing C batteries, consider their shelf life. Alkaline batteries have a shelf life before they must be thrown away. "Shelf life" refers to rechargeable batteries' number of charges before being replaced. We recommend C batteries that last at least five years but the best last ten.



Studying battery chemistry, battery design and engineering, brand, and other factors are crucial to finding the best batteries for each use. Everyone must follow the proper steps for storing, handling, using, throwing away, and recycling the battery. With this, you're assured of choosing the best C battery of your preference.

In need of a C battery? Carefully follow the various guidelines provided, and you will find satisfaction when using a C battery.


Frequently Asked Questions About C Battery

🔋Can You Recycle C Batteries?

Yes. All common battery sizes, including C batteries, can be recycled together. Certain municipalities' regular trash collection programs include battery disposal.

In other places, the old batteries are taken to a collection point to ensure proper disposal. The parts of old batteries are taken apart so they can be used again.

🔋Can you use C batteries in place of D?

A few quarters may suffice if you have only C batteries for a device requiring D batteries. It is not an ideal long-term solution, but it will suffice in a crisis. Most batteries may be replaced for three or four quarters, which is less than one dollar.

🔋Do C batteries have more power than AA?

C batteries have the same 1.5 V voltage as AA and AAA cells but have an 8,200-mA capacity. The 12.3 watt-hour gap between AA and AAA batteries and C batteries indicates the variance in battery capacity between the three sizes.

🔋What is the difference between AA AAA C and D batteries?

At this point, the size of the battery matters. The current rating of the D-size battery is higher than that of the C, AA, and AAA sizes. Even though AA and AAA batteries have a rating of 1.5 voltage, the AA battery generates a higher current than the AA battery.
