Selecting the right type of battery is important when it comes to powering your devices. Two of the most commonly used household batteries are C and D batteries. However, there are significant differences between these two batteries that you should be aware of before making a decision. In this article, we will provide a side-by-side comparison of C and D batteries to help you choose the best one for your needs.
Understanding C Batteries:
C batteries are cylindrical batteries that are 50.5mm in length and 26.2mm in diameter. The “C” in C battery refers to the size of the battery, which is cylindrical in shape. These batteries have a capacity of around 1.5V and can deliver a moderate amount of power over an extended period. The C battery size is intermediate between AA and D batteries, making it a popular choice for a variety of devices such as flashlights, toys, and portable radios.
C batteries are also known as R14 batteries. The cylindrical shape of C batteries is standardized by the International Electrotechnical Commission (IEC), and it was given the letter designation “C.” The letter designations for battery sizes were established to create a standard for manufacturers and consumers, making it easier to identify and compare different battery sizes.
Advantages and Disadvantages of Using C Batteries
One of the main advantages of C batteries is their long life. They are designed to last for several years, making them a cost-effective choice for devices that are used infrequently. Another advantage of C batteries is their versatility. They can be used in a variety of devices, including toys, flashlights, and portable radios.
However, one of the disadvantages of C batteries is that they are not as powerful as other types of batteries. This makes them unsuitable for high-power devices. Additionally, C batteries are not as widely available as other battery types.
Understanding D Batteries:
D batteries are cylindrical in shape and have a standardized size, which is designated by the letter “D.” The International Electrotechnical Commission (IEC) established letter designations for battery sizes to make it easier for manufacturers and consumers to identify and compare different battery sizes.
Compared to C batteries, D batteries are larger in size, measuring 61.5mm in length and 34.2mm in diameter. With a capacity of around 1.5V, D batteries have a higher power output than C batteries, making them ideal for high-power devices that require a lot of energy to operate, such as flashlights, radios, and lanterns.
Advantages and Disadvantages of Using D Batteries
One of the primary advantages of using D batteries is their high power output, which makes them a suitable choice for devices that require a lot of energy. However, D batteries are not as cost-effective as C batteries and may need to be replaced more frequently due to their shorter lifespan.
Choosing the right battery for your device
When choosing between C and D batteries, it’s important to consider the specific needs of your device. If you’re looking for a battery that has a longer lifespan and is suitable for low-power devices, C batteries may be the better choice. However, if you need a battery that delivers high power output for high-power devices, D batteries are the way to go.
When it comes to cold cranking amps (CCA), D batteries have a higher rating compared to C batteries, which means they can deliver more power and start engines more easily in cold weather. D batteries also have a higher discharging rate compared to C batteries, meaning they can discharge more energy in a shorter amount of time. Moreover, D batteries have a wider temperature tolerance, so they can function in a wider range of temperatures.
In conclusion, when choosing between C and D batteries, it is essential to consider the battery’s lifespan, capacity, CCA, discharging rate, temperature tolerance, cost, and compatibility with your device. By keeping these factors in mind, you can make an informed decision and choose the right battery for your needs.

Note: The table provides a brief overview of the key characteristics of C and D batteries, but it is important to check the specifications of your device to ensure that you choose the right type of battery. Some devices may require a specific type of battery, while others may be compatible with either C or D batteries.
Comparison of Chemistry Between C and D Batteries
While C and D batteries use the same principle of electrochemical reactions, the number of active materials in the battery and their size affects their overall performance. Here’s a closer look at the chemistry of C and D batteries:
C Battery Chemistry
The anode in a C battery is typically made of zinc, which oxidizes to form zinc ions and electrons. Meanwhile, the cathode is made of manganese dioxide and is reduced when the battery is in use, forming manganese oxide and water. This creates an electrical potential difference, which generates a flow of electrons and provides power to the device.
D Battery Chemistry
Like the C battery, a D battery typically has a zinc anode and a manganese dioxide cathode. The cathode, when reduced during use, produces manganese oxide and water, which creates an electrical potential difference to provide power to the device.
Some common battery equivalents for C and D batteries:
C Battery Equivalents:
- AA Battery: A single AA battery is about the same size as a C battery, but has a higher energy capacity due to its smaller size.
- 9V Battery: A 9V battery is larger and more powerful than a C battery, and is not a direct equivalent in terms of size or voltage.
- D Battery: A single D battery is often equivalent to two C batteries in terms of voltage and overall energy output.
- AAA Battery: AAA batteries are smaller than C batteries and have a lower voltage and energy output, but can be used in some devices designed to use C batteries.
D Battery Equivalents:
- C Battery: Two C batteries can be used in place of a single D battery, as they provide a similar voltage and energy output.
- AA Battery: AA batteries are smaller than D batteries and have a lower voltage and energy output, but can be used in some devices designed to use D batteries.
