Cr2 vs Cr123

 

In order to get the maximum performance from your electronic devices, choosing the right battery is crucial. It is common to consider CR2 and CR123 batteries when considering lithium batteries. In order to ensure compatibility with your devices, you must understand the differences between these batteries. We will examine sizes, capacities, and applications to help you better understand the differences between CR2 and CR123 batteries. So if you want to learn about the Cr2 vs Cr123, then just continue reading our article till the end!

What does the CR stand for?

Lithium-chemistry batteries are identified by the prefix CR in the IEC. Batteries such as LiMnO2 (Lithium-Ion Manganese Oxide) are commonly used. R indicates that the batteries are round, and C indicates that they are lithium. Batteries are sized according to the numbers that follow. The 123A battery has a size that's two-thirds that of a regular A battery. The A may be omitted by some manufacturers. 

 

What is a CR123 Battery?

A CR123 battery has a high power rating of 3V and is small and lightweight. A variety of small gadgets, such as alarm clocks, flashlights, cameras, and watches, use these batteries. Between 1,500 mAh and 2,500 mAh is their typical power capacity. 

 

They can handle continuous currents of 1,000mA - 2,000mA and pulse currents of 3,000mA depending on the brand. These batteries are rated at mAh (milliamperes), which means that they can supply power to devices drawing 100 mA (milliamperes) for as long as 30 hours.

 

Note: Batteries are rated by milliampere hours (mAh) in order to determine their energy capacity (how much power they can produce and for how long).

 

What is a CR2 Battery?

CR2 Battery

 

A cylindrical cell battery with lithium chemistry is referred to as a CR2 battery. CR2 batteries resemble smaller versions of D-cell batteries, or even like cans for simplicity's sake. Various applications can be achieved with these batteries. These batteries are mostly used in cameras as well as many industrial applications that need high power lithium batteries. As the battery has so many uses, it is often difficult to find in stock because it is so popular. Panasonic, Duracell, and Energizer are among the brands that produce them.

Cr2 Vs Cr123

Technology has become extremely important in this time period. Humans use technology at an incredibly high rate in their daily lives. The number of electrical devices owned by everyone exceeds five, sometimes it is too high. Some of these devices require a portable electric connection, even when they don't directly connect to the electricity.

 

Taking pictures is possible with the help of a camera, for example. Taking the time to travel is something people do. The main electricity supply cannot be reached while traveling. Electricity, however, is required to operate the camera. An electric battery is the solution.

 

Chemical reactions inside batteries produce electricity by storing chemicals and producing electricity through chemical reactions. A battery works on a simple principle. Electrons are transferred from one metal to another in the chemical to produce electricity. Cell chemistry may be familiar to some. Cell chemistry is demonstrated in the construction of the battery. Three main components make up a cell.

 

Electrodes and electrolytes are its two basic types. A separator, a container, and terminals complete the system. A cathode and an anode are the essential components of the system. Cathodes are positive electrodes and anodes are negative electrodes. Therefore, the positive energy is present in the cell. During a circuit reaction, the anode reduces electrodes. Positive electrodes accept electrons from external circuits, while cathodes reject them.

 

Electrolytes are the most important component after anodes and cathodes. Charges are transferred through ions through it. Between the anode and cathode, ions transfer electricity. Depending on the arrangement, the battery can contain one or more cells like described above.

CR2 vs CR123: Batteries

In this section, we will discuss the batteries cr2 and cr123. People commonly use these two types of batteries. Their power and size made them popular. It is common for people to get confused between batteries when choosing them. So, they need to know which one is the better one. There is nothing difficult about discussing and telling about it. These two batteries differ quite a bit from one another. Those specifications are, in order to understand the differences, the following:

Construction

Manufacturers of cr2 and cr123 use lithium in their main constructions. A high-quality battery should be made from lithium, which is lightweight and has high energy density.

Volts

The voltage of cr2 and cr123 is 3 volts. As a result, both batteries have many similarities. It is important to pick the exact volt when changing a battery for any specific device. The circuit of the device can be damaged by a higher voltage.

Dimension

Differences between cr2 and cr123 are most visible in their dimensions. There are differences in the dimensions of both batteries. It is important to consider the physical dimensions of the battery carefully when replacing one battery with another. There are 34.5 mm of length and 17 mm of diameter in the battery CR123. While the CR123 battery is 35mm long, the CR2 battery measures 27mm long, which is 6.5mm shorter. There is a 2.6mm difference in diameter between CR2 and CR1.

 

As a result of their dimensions, it is evident that they can't be replaced with one another. As the battery holder size in a device is fixed. Neither can it be extended nor minimized.

Run Time

Based on the mAh rating, this battery will run for a very different amount of time. CR2 batteries run for a shorter period of time due to their lower mAh rating. There will be 5.5 to 8 hours of battery life on this battery. Batteries with CR123s, however, have a lifespan of between 6 and 50 hours. Due to its high mAh rating, the battery has a longer runtime.

Charging Option

Electronic devices are most commonly powered by rechargeable batteries. Unfortunately, neither cr2 nor cr123 batteries can be recharged. If the battery is fully discharged, it cannot be recharged. Due to their lower discharge rates, both batteries last longer than other batteries. The charge is lost by 5% per month if they are used regularly. The fact that it can be used for a longer period of time makes it a good choice.

mAh Rating

The mAh rating of cr2 and cr123 is one of the most significant differences between the two. CR2 batteries are rated between 400 and 800 mAh, whereas Cr123s are rated between 1500 and 2500 mAh. There is a big difference between the two. Because these batteries have different characteristics, they are applicable to different situations.

Which battery type are CR2 and CR123?

The two main types of batteries are sealed batteries and rechargeable batteries. It is divided into two categories: primary and secondary. It is necessary to look closely at their specifications in order to know what type of CR2 and CR123 they are. One type of battery is non rechargeable, while the other is rechargeable. Furthermore, CR2 and CR123 batteries cannot be recharged, which validates the second point. When the batteries run out of charge, they cannot be recharged or reused. The primary battery is thus them.

Cr2 Vs Cr123: Which one is the best fit?

User needs will determine whether to use CR2 or CR123 batteries. It is their responsibility to choose the type they need for their device if it requires a particular type. Choosing the right battery type is also influenced by the battery holder space of the device. It is also not possible to use a 5V battery if the device requires a 3V battery. The main circuit of the device can be damaged by high voltages. So, when choosing batteries or devices, one must be specific.

 

In contrast, CR123 batteries are an option if one wants a long-lasting battery. They have a high mAh rating, which makes them durable and long lasting. The CR2 battery, however, is ideal for small flashlights. You will be able to work for a short period of time with it since it is lightweight. As far as what the user needs is concerned, it's up to them.

Answer: Battery storage at a cool, dry place will typically extend the shelf life of both CR2 and CR123 batteries. Make sure the battery packaging is marked with the date of expiration or manufacture before use.

Final Verdict

Most people think of CR2 and CR123 batteries when it's time for them to replace their non-rechargeable batteries. Since both share the same voltage, many people believe they are the same. The size of the battery holder on their device is one of the most important details they forget when it comes to replacing the battery. Although both batteries share the same size, their power is different. These batteries cannot be interchanged mainly because of their dimensions.
