D vs C Battery: Which Battery is Better

Introduction

D and C batteries are both cylindrical batteries that are commonly used in a variety of electronic devices, such as flashlights, portable radios, and toys. However, they differ in size and capacity, which makes them better suited for different applications.

D batteries are the larger of the two, with a diameter of 33.2mm and a height of 61.5mm. They are commonly used in devices that require a lot of power, such as high-powered flashlights, lanterns, and boom boxes. D batteries typically have a capacity of around 10,000 milliampere-hours (mAh), which means they can provide more power than smaller batteries and last longer before needing to be replaced.

C batteries, on the other hand, are smaller and more compact than D batteries, with a diameter of 26.2mm and a height of 50mm. They are commonly used in smaller electronic devices, such as portable radios, toys, and small flashlights. C batteries typically have a capacity of around 6,000 milliampere-hours (mAh), which means they have less power than D batteries and may need to be replaced more frequently.

When choosing between D and C batteries, it’s important to consider the power requirements of the device you are using them in. If you are using a device that requires a lot of power, such as a high-powered flashlight or boombox, D batteries may be the better choice. If you are using a smaller device, such as a portable radio or toy, C batteries may be more appropriate. It’s also important to consider the cost and availability of the batteries, as D batteries tend to be more expensive than C batteries due to their larger size and capacity.
