Things to Keep in Mind When Buying The Best CR123a Battery


Milliamp hour or mAh is a unit that measures the energy capacity of a battery. It measures the electric power the battery can deliver over time. Generally, a higher mAh indicates higher battery life. But comparing the mAH of batteries powered by two different chemicals will not give us any useful information.

Alkaline batteries may have higher capacity ratings than lithium batteries, but when used in high draining devices they run out of power way quicker. Lithium batteries on the other hand have a run time that’s at least three times that of alkaline batteries.

However, you can compare the capacities of batteries powered by the same core chemical.

CR123 batteries come in rechargeable as well as non-rechargeable variations. The rechargeable variations have a lower mAh than the non-rechargeable ones which means they run out of power faster.

Typically non-rechargeable CR123s have a capacity of 1,500 mAh and rechargeable ones have ratings of 500 to 800 mAh.

Shelf Life

Non-rechargeable lithium batteries such as the CR123a have the longest shelf life out of all other kinds of batteries. They can be stored in a battery storage container for up to 10 years or 12 years before they begin to deteriorate.

Rechargeable lithium batteries on the other hand do not have such a long shelf life. After a year of storage, they lose 10% to 30% of their capacity to store charge. At most these batteries have a shelf life ranging between two to four years.


Lithium batteries are usually pricier than alkaline batteries. However, they can be used on high-draining devices and they last longer. In the long run, getting batteries that last longer works out to be cheaper.

Since non-rechargeable lithium batteries have a higher capacity than rechargeable ones,  they are more expensive. Once they run out of charge you will have to throw them out and get new batteries as well.

This makes rechargeable lithium batteries an attractive option to those looking to save some money in the long run. Not only is the initial investment cheaper, but you also won’t have to keep spending money every time your batteries are out of charge.

This also means that rechargeable batteries create less waste than disposable ones making them an eco-friendly option as well.

Frequently Asked Questions

CR123 vs CR123A What Is the Difference?

There is no significant difference between the chemical properties of CR123 and CR123a cells. They are interchangeable batteries that can be used in a variety of electrical devices.

Both CR123 and CR123a are cylindrical lithium-ion batteries that typically have a diameter of 17 mm. The difference exists only in labeling. The labeling changes depending on the manufacturer but they are essentially the same. CR123a batteries are also known as K123A, EL123AP, 5018LC, VL123A batteries.

However, there are differences between rechargeable and non-rechargeable CR123a batteries. Both have their specific applications and you must be careful when interchanging the two kinds.

The non-rechargeable variation is a disposable battery that is meant for one-time use only. They usually have a nominal voltage of 3V and a capacity of 1500 mAh. You can check the state of your batteries using a small household battery tester, this will show you the voltage and condition of the battery.

The rechargeable variation is a reusable battery that has a voltage ranging between 3.6 and 3.7 volts and a capacity ranging between 500 to 800 mAh.

For How Long Will My CR123a Battery Last?

The life of a CR123a battery while in use will depend on the equipment being powered using the battery. People usually get CR123a batteries as they have a high-energy output that can power high-drain devices for longer durations than regular alkaline batteries.

Disposable batteries of 1500 mAh will obviously last longer before they have to be replaced than rechargeable batteries with capacities ranging between 500 and 800 mAh.

If you are looking to store batteries for future use, disposable CR123a batteries have a longer shelf life than rechargeable ones. In fact, disposable batteries have a shelf life of 10 years.

How Many Volts Is a CR123a Battery?

Non-rechargeable CR123a batteries have a nominal voltage of 3 volts. This means that they can be safely used in a variety of electrical equipment including high-drain devices.

Rechargeable CR123a batteries usually have a higher voltage ranging from 3.6 to 3.7 volts. This means that you should be careful when using rechargeable batteries in your equipment as sensitive devices may malfunction due to the higher voltage.

Check your device’s voltage requirements before using any kind of battery to ensure optimal performance.

Final Thoughts

There are many reasons to consider switching to CR123a batteries. They are economical in the long run as they last longer than regular batteries and have a longer shelf life. Since you need to replace them less often you are also generating less waste.

And if these reasons aren’t compelling enough, their high-energy output and stable voltage optimizes the performance of your equipment and prevents it from malfunctioning.

There are three things to keep in mind when buying CR123a batteries—Mah, shelf life and price. This detailed overview of the best CR123a batteries on the market helps you compare these features and choose the brand that suits your needs.
