Difference Between D2 And D3 And D4 And D8 Batteries | KET

D2, D3, D4, and D8 batteries are all types of cylindrical batteries, but they have different sizes and capacities.



D2 batteries, also known as 2D batteries, have a diameter of 25.2mm and a length of 34.2mm. They have a typical capacity of around 4000-5000mAh. They are commonly used in electronic devices that require a moderate amount of power, such as portable radios, flashlights, and portable speakers.

D3 batteries, also known as 3D batteries, have a diameter of 25.2mm and a length of 50.5mm. They have a typical capacity of around 6000-7000mAh. They are commonly used in electronic devices that require a moderate to high amount of power, such as portable radios, flashlights, and portable speakers.

D4 batteries, also known as C batteries, have a diameter of 26.2mm and a length of 50.5mm. They have a typical capacity of around 8000-10000mAh. They are commonly used in electronic devices that require a large amount of power, such as portable radios, flashlights, and portable speakers.

D8 batteries, also known as 8D batteries, have a diameter of 34.2mm and a length of 61.5mm. They have a typical capacity of around 20,000-25,000mAh. They are commonly used in large electronic devices that require a lot of power, such as backup generators and portable power stations.

In summary, D2, D3, D4, and D8 batteries are all types of cylindrical batteries, but their sizes and capacities make them appropriate for different applications. D2 and D3 batteries have smaller size and lower capacity, while D4 and D8 batteries have larger size and higher capacity.
