Cylindrical Battery Cell Sizes, Capacity, Dimensions, and Types

Cylindrical batteries are one of the most common types of batteries used in various applications due to their high energy density, low cost, and reliable performance. They are typically cylindrical in shape and come in a range of sizes and capacities to suit different applications. In this article, we’ll take a closer look at the different cylindrical battery cell sizes, capacity, dimensions, and types.

Cylindrical Battery Cell Sizes

Cylindrical batteries come in various sizes, and each size has a unique name and code. The most commonly used cylindrical battery sizes include:

1. AAAA (also known as LR61): This is the smallest cylindrical battery size and has a diameter of 8.3mm and a length of 42.5mm. It is commonly used in small electronic devices such as laser pointers and penlights.
2. AAA (also known as LR03): This battery size has a diameter of 10.5mm and a length of 44.5mm. It is commonly used in small electronic devices such as remote controls and flashlights.
3. AA (also known as LR06): This battery size has a diameter of 14.5mm and a length of 50.5mm. It is commonly used in various electronic devices such as digital cameras, toys, and flashlights.
4. C (also known as LR14): This battery size has a diameter of 26.2mm and a length of 50mm. It is commonly used in medium-sized electronic devices such as radios and portable speakers.
5. D (also known as LR20): This battery size has a diameter of 34.2mm and a length of 61.5mm. It is commonly used in larger electronic devices such as flashlights and portable fans.

Cylindrical Battery Capacity

Cylindrical batteries are available in different capacities, which are measured in milliampere-hours (mAh). The capacity of a battery refers to the amount of energy it can store and how long it can power a device. The higher the capacity, the longer the battery will last. The capacity of cylindrical batteries can range from a few hundred mAh to several thousand mAh, depending on the size and type of battery.

Cylindrical Battery Dimensions

Apart from the size and capacity, cylindrical batteries also have different dimensions, which include the diameter and length of the battery. The diameter of cylindrical batteries typically ranges from 8.3mm to 34.2mm, while the length can range from 42.5mm to 61.5mm. The dimensions of the battery will determine whether it can fit into a specific device or battery holder.

Cylindrical Battery Types

There are different types of cylindrical batteries, each with its unique characteristics and applications. Some of the most commonly used cylindrical battery types include:

1. Alkaline batteries: These are the most common type of cylindrical batteries and are designed for single-use applications. They are relatively inexpensive and offer good performance.
2. Nickel-cadmium (Ni-Cd) batteries: These batteries are rechargeable and have a higher energy density than alkaline batteries. They are commonly used in portable electronic devices such as cordless phones and power tools.
3. Nickel-metal hydride (Ni-MH) batteries: These batteries are also rechargeable and have a higher energy density than Ni-Cd batteries. They are commonly used in portable electronic devices such as digital cameras and MP3 players.
4. Lithium-ion (Li-ion) batteries: These batteries are rechargeable and have the highest energy density of all cylindrical batteries. They are commonly used in high-performance electronic devices such as laptops and smartphones.
