What is a Cr123a Battery?

The CR123A battery is a type of lithium battery. It's called CR123A because the "CR" indicates the lithium chemistry, specifically LiMnO2.

The size of the CR123A battery is a key part of its name, with "23A" referring to its dimensions. In this case, it's 2/3 the length of a standard A-size battery.

This battery meets industrial testing standards, giving you peace of mind when using it.

Why is it called a Cr123a?

The CR123A battery gets its name from a combination of its chemistry and size. The "CR" prefix indicates that it uses lithium chemistry, specifically LiMnO2.

The "123A" part of the name refers to the size of the battery. It's 2/3 the length of a standard A-size battery.

A battery is essentially a container that stores energy in the form of chemical energy, which can be converted into electrical energy when needed.

Batteries come in various shapes and sizes, but the CR123A battery is a specific type that has a cylindrical cell shape, similar to a smaller version of a C Cell Battery.

These batteries are widely used in many applications, including medical devices and military-grade technology.

The CR123A battery is made with lithium chemistry, which is a type of battery chemistry that is known for its high energy density and long lifespan.

The shape of the CR123A battery is also often described as resembling a can, which can be a helpful reference for those who are unfamiliar with the battery's appearance.

Battery Options and Alternatives

The CR123A lithium 3 volt battery is a popular choice, but if you're looking for alternatives, there are a few options to consider.

The 16340 battery is a direct equivalent in terms of size and shape, but it uses a lithium-ion chemistry that's rechargeable and can provide similar performance to a CR123A.

However, it's worth noting that the 16430 battery may not offer the same performance or lifespan as a CR123A, even though it will fit in the same locations.

Sometimes, but not always, you can use 2 x AA batteries instead of an 18650 battery. Some devices have long, spring-loaded interiors to account for varied battery length, allowing 2 x AA batteries to squeeze in.

You may need a battery sleeve for a secure connection, as AA batteries are slightly thicker than 18650s.

Do Rechargeable Batteries Exist?

Yes, rechargeable batteries do exist. They are often referred to as RCR123A or 16340 batteries.

RCR123A batteries are a type of rechargeable battery that is slightly shorter than CR123As. They utilize lithium-ion chemistries and have lower energy capacities.

These batteries usually have a 3.6 – 3.7 voltage, and not all devices can use both CR123As and their rechargeable counterparts.
