What is a Battery?

A battery is a compact energy storage device designed to fit into devices where space is limited.

Manufacturers define these devices by their small dimensions, ranging from a few millimeters to a few centimeters.

Batteries are crucial for powering electronic devices, from smartphones to medical equipment, where larger batteries would be impractical.

These devices store energy in a compact form, making them essential for our daily lives.

Alkaline batteries are one of the most common types of small size batteries. They have a long shelf life, lasting up to 10 years when stored properly.

Their relatively low cost and wide availability make them a popular choice for everyday use.

Alkaline batteries are also known for their high energy density, which means they pack a lot of power into a small package.

They're widely used in household devices such as flashlights, toys, and remote controls.

Battery Applications

Small batteries are incredibly versatile and find their way into a wide range of applications, particularly in devices where space is limited.

In wearable technology, small size lithium batteries power smartwatches, fitness trackers, and health monitors, keeping them lightweight and comfortable for users.

Medical devices such as hearing aids, insulin pumps, and portable diagnostic tools rely on small batteries for reliability and longevity.

Consumer electronics like remote controls, digital cameras, and portable gaming consoles also benefit from small size batteries, which deliver high energy density compactly.

The Internet of Things (IoT) devices, including sensors, smart home devices, and wearables, require long-lasting power in a small package, making small-size lithium batteries a vital component.

Drones and robotic devices, too, rely on small batteries to provide the necessary power for flight and operation without adding significant weight.

CR Battery Information

CR batteries come in various sizes, each with its own specifications that impact performance. Choosing the right size ensures optimal performance from your battery.

A CR battery size chart can help you determine which size is best for your device. For example, the CR1025 battery is 10.0 mm in diameter and 2.5 mm in height, with a capacity of 35-45 mAh, making it suitable for key fobs and small devices.

Here are some common CR battery sizes and their applications:

CR batteries typically have a voltage of 3.0 volts, which is consistent across most sizes, making it easy to use different sizes interchangeably.

CR Battery Naming Convention

The CR battery naming convention may seem like a mystery, but it's actually quite straightforward. The most common format follows the pattern CR####, where the "C" and "R" represent the lithium chemistry and the round shape.

The numbers that follow provide crucial details about the battery's size and capacity. Let's break it down:

The first two digits (e.g., 20 in CR2025) represent the diameter of the battery, measured in millimeters (mm). This is important to know because the diameter of the battery needs to match the device it's going into.

The last two digits (e.g., 25 in CR2025) indicate the thickness (or height) of the battery, also in millimeters. A thicker battery can be a problem if it doesn't fit in the device.

For example, the CR2025 battery has a diameter of 20 mm and a thickness of 2.5 mm. Other common CR battery sizes follow the same pattern, such as CR1632 (diameter of 16 mm, thickness of 3.2 mm) and CR2032 (diameter of 20 mm, thickness of 3.2 mm).

Here are some common CR battery sizes to keep in mind:

CR Battery Voltage

CR batteries typically have a voltage of 3.0 volts, a key factor in their widespread use. This consistent voltage makes it easy to use different sizes interchangeably.

The voltage determines the amount of energy that the battery can deliver to the device. 3.0 volts is relatively high for such a compact form, which is why CR batteries are so effective at providing consistent power for extended periods.

In most cases, the voltage won't change much from one size of CR battery to another. However, the capacity does change, which affects how long the battery lasts before it needs to be replaced.

Battery Sizes

Lithium-ion batteries come in various sizes, each with its own unique characteristics. The size of a lithium-ion battery is often represented by a five-digit code, with the first two digits indicating the diameter, the next two digits indicating the height, and the final digit indicating the type.

The most common sizes include 10440, 14500, 16340, 18650, 21700, and 26650. These sizes vary in capacity, with the 18650 battery having a capacity of 1500-4000mAh, while the 21700 battery has a capacity of 3000-6000mAh. The 26650 battery, on the other hand, has a capacity of 2400-6000mAh.

Here is a list of some common lithium-ion battery sizes and their corresponding capacities:

These sizes are used in a variety of applications, including laptop computer batteries, cordless power tools, and electric vehicles.
