What are the Differences Between C and D Battery

The two most commonly used batteries options are C and D type batteries when using the best batteries for medium and high drain applications. Some experts claim that both are interchangeable and could use for similar applications, while others have the opposite opinion.

They have similar features that may make them switchable, but what is the truth? Continue reading C vs D battery comparison.

There are 8 differences between C and D type Batteries

1. Voltage

The most confusing thing that makes us double-minded is that both of the batteries provide the same voltage of 1.5, so for that reason, people think both of the batteries are interchangeable.

2. Capacity

While comparing voltage, we were also confused because both provide the same, but when checking their capacity, we found power’s main point. Undoubtedly both batteries offer 1.5 voltage, but D batteries are more powerful and suitable for devices that need more current. 

The capacity comparison reveals that the D battery has a power capacity of up to 17000mAh that is very high than the C battery, which is only 8000 mAh. 

3. Types

C and D batteries are divided into different types on their composition base. C batteries have three types of composition NiMH, NiCd, Li-ion, while the D batteries have only two types of composition, NiMH and Li-ion. 

4. Size

Size is one of the significant factors to consider when comparing batteries because based on size, different batteries differentiate from each other for different applications. There is a considerable difference in their size which means the C battery is not best suited to the D battery. The D battery has a larger size, 61.5mm X 33.2mm, than the C battery, with only 50mm X 26.2 mm size. 

5. Weight

In comparing their weights, we found that the D battery has more weight, almost double the size of the C battery. The average weight of C batteries ranges from 60 to 65 grams, while the average size of D batteries ranges between 160 to 180 grams.

6. Supported Devices

C batteries provide 1.5 volts that make them compatible with many small, medium, and high drain applications. But D batteries not just provide 1.5 volts but also ensure enough power that makes them perfect for high drain applications.

7. Working Hours

C battery could supply power for continuous 18 hours while the D batteries could supply for 36 hours that is double as compared to C batteries.

8. Average Life

The average life of C batteries is between 3-5 years, while D batteries have an average life of 2-3 years.


C and D batteries are common for small, medium, and high drain applications. Sometimes they are also interchangeable, but D batteries are efficient and ensure consistent performance compared to C batteries due to efficient features.
