CR123 and CR123A are two batteries that are quite popular in the world of electronics and here are some solid reasons behind their massive popularity. Affordability and availability are among the top reasons behind their popularity.

Additionally, both are top-performing batteries. Of course, this is something that you should expect to get from lithium-based batteries. They are designed to deliver the desired performance levels in their respective application areas.

However, the biggest issue is, which one should you buy between CR123 and CR123a? this is a question that most buyers tend to ask.

Before you take that step of purchasing the battery, you should start by knowing the differences between them. To help you make the right decision, we are going to discuss in detail the differences between CR123 vs. CR123a.

What is a CR123 battery?

CR123  is a small 3V lithium-ion battery used in many small devices such as cameras, flashlights, and alarms, among other electronics. The battery is also used in some commercial and military applications.

The power capacity of most CR123 batteries ranges between 1500mAh and 2500mAh. With these figures, it means that most CR123 batteries can easily supply power to a device that is designed to draw power of 100mA for up to 30 hours. The  operating current of CR123 batteries  ranges 1000mA and 2000mA

What is CR123A battery?

CR123A battery is always considered an upgraded version of the CR123 battery. It is also a lithium-ion battery that is designed for small devices and gadgets such as cameras, and alarms, among others.

The power capacity of the CR123A  battery is similar to that of the CR123. It also ranges between 1500mAh and 2500mAh. However, it has a slightly higher operating current which ranges between 1500 mAh and 2500 mAh.

Differences between CR123 vs CR123A

 Let’s look at the main differences  between CR123 and CR123A;

Size

 This is the main difference between CR123 and CR123A. While both are small lithium-based batteries that are designed to fit into small devices, there is a slight difference in terms of their dimension.

CR123 batteries are slightly longer than the CR123A. They are also thinner, meaning that the latter has a larger width than the CR123A. The difference  is not more than 0.55mm

However, compared to the AA alkaline batteries, both CR123 and CR123A are shorter yet still deliver better performance. They are also thinner.

Durability

 Which is more durable between CR123 and CR123A? When used at the right temperature conditions, both batteries will give you a lifespan of 10 years.

In other words, CR123 and CR123A are durable batteries that will serve their purpose for a long.

However, the durability of these lithium-ion batteries will depend on their storage and usage. Some gadgets are known for draining the durability of batteries at faster rates than others. Of course, this is accompanied by how you handle the battery, and the device that uses the battery.

Voltage

Both CR123 and CR123A have a nominal voltage of 3 volts. However, the standard voltage of these batteries ranges between 2 and 2.5 volts.

With the same voltage ratings, these two batteries can be used for devices with the same power requirements. Also, 3 volts is enough to power most devices. What makes them more desirable is they can provide adequate power despite their small sizes.

Chemical composition

 CR123 and CR123A are lithium-ion batteries. Their chemical compositions comprise Lithium and Manganese dioxide (LiMn02).

The positive terminal (Cathode) of both batteries is made of manganese dioxide that is heat-treated. The chemical composition of these batteries is credited for their electrical properties.

Safety levels

Which one is safer between CR123 and CR123A?  Lithium is quite a dangerous chemical especially when exposed to extremely high voltage or when it comes to direct contact with the skin.

Since both batteries have safe chemical properties, their safety is at the same level.

Furthermore, both CR123 and CR123A come with temperature protection features that disconnect the battery from the circuit in case of an overcurrent.

Which should I choose between CR123 vs CR123A?

After analyzing the differences between CR123 and CR123A, which one should I choose?

 The main difference between these two batteries is the letter A. Otherwise, they have the same physical and electrical properties. They will deliver the same level of performance in their respective application areas.

Perhaps you may raise issues regarding their dimensional difference. However, The difference is barely unnoticeable. This means that the two batteries are interchangeable: You can use CR123 in the place of CR123A and vice versa.

 Regardless of the battery that you choose, you should be careful with the brand. This is because CR123 and CR123A batteries are manufactured by different brands. Ensure that you buy from reputable brands as you can be assured of the quality and reliability of the battery.
