Best CR123A Battery [Buying Guide]

best cr123a batteryCR123A batteries are lithium batteries and have lightweight cells with large voltages. These batteries work well for a variety of applications that need high power. In this blog post, we’re going to help you find the best CR123A battery for your devices. Initially, CR123A batteries were designed for digital cameras. Today, people use them for LCDs, bright flashes, flashlights, security cameras, home automation, toys, smoke detectors, tactical equipment, and more.

In general, CR123A’s are 1.31 inches long, 0.55 inches in diameter, and 0.6 oz. in weight, which makes them smaller than AA batteries (1.94 inches in length, 0.57 inches in diameter, and 1.1 oz. in weight). CR123A batteries generate more voltage than AA batteries. Each cell produces a maximum voltage of 3 volts.

The power-to-size ratio makes CR123A batteries ideal for devices like LED flashlights. Compared to 2 AA batteries that generate 3 volts, 2 CR123A batteries in series can produce 6 volts. PTC protection circuits can protect these batteries from various issues. PTC disconnects the circuit between the terminals of the battery when there is high voltage or current.

CR123A batteries come in rechargeable and non-rechargeable versions. These replace common batteries, such as 5018LC, VL123A, L123A, K123LA, and BR2/3A. Some common brands of C123A batteries are Panasonic, Tenergy, Duracell, and Energizer. In today’s post, we will review the best CR123A battery products. Read on!

Best CR123A Battery – Buying Guide

Initially designed for digital cameras, people are now using CR123A batteries to operate different devices, such as Arlo security cameras, flashlights, tactical equipment, toys, and electronics. 

There are many brands and products available on the market. However, choosing the right one is not always easy. That’s why we have created these buying criteria to help you purchase the best CR123A battery. 

Rechargeable VS Non-Rechargeable

CR123A battery has a cylindrical structure that features 1.31 inches height and 0.55 inches diameter. Commonly known as “CR123A battery,” it is also labeled as K123A, CR17345, RCR16340, DL123A, VL123A, SF123A, 5018LC, EL123AP, and others. But, in general, all these batteries are categorized under the CR123A battery. There are two main types of CR123A batteries: rechargeable and non-rechargeable batteries.

Rechargeable: Typically, it is labeled as an RCR123A battery, which has a higher voltage ranging from 3.5 volts to 3.7 volts. Rechargeable CR123A has a higher capacity that ranges from 500mAh to 800mAh. Some brands like RAVPower that manufactures CR123A batteries have capacity up to 1500mAh.

Non-rechargeable: IT has 3v nominal voltage and 1500mAH capacity. On average, the shelf life of the most popular non-rechargeable products is 7 to 10 years. If you want batteries for your standby devices, such as security devices and EDC flashlights, choose the non-rechargeable batteries. These batteries can optimally tolerate high drain currents.

The obvious primary difference between them is that you can use a rechargeable battery once it has been discharged, while you can’t use a non-rechargeable battery after it has been fully discharged.

Rechargeable batteries are usually more expensive than non-rechargeable batteries. A non-rechargeable battery can last longer than a rechargeable battery, but you can use it until it discharges.

Non-rechargeable batteries are an ideal choice for low-drain devices that use low power for their function. Rechargeable batteries, in contrast, are an excellent choice for high-drain electronics and gadgets.


Alkaline batteries can undergo steep voltage drops, which don’t make them an ideal choice for security applications. On the other hand, CR123As maintain a steady voltage curve, which generates higher power for battery life.

Dropping voltage can lead to erratic performance that can damage your smart security system. So, if you are using a WiFi security system, make sure you choose a battery with a capacity ranging from 600mAh to 900mAh.

Home automation: Although you can wire your home automation devices like speakers and lighting into your property and power them from the electrical network, small sensors, including motion detectors and doorbells require you to power them via batteries. Remember, CR123A batteries will sit idle until stimuli activate the sensor. That’s why to choose a CR123A battery that has a longer shelf life.

Smoke Detectors: Your home security system has an essential component known as a “smoke detector,” which requires continuous power to perform optimally. When it comes to choosing the best CR123A battery for such a device, choose a battery that has lithium manganese dioxide composition. For instance, the interstate CR123A battery is best for your smoke alarms.

LED Lights: Some people choose AA batteries for their illumination equipment, such as LED lights. However, we don’t recommend them. CR123A battery works much better for LED lights than AA batteries. For instance, a battery with 17mm diameter and 34.5mm length is an optimal choice for LED lights.

Scopes & Laser Rangefinders: If you are looking to buy the best CR123A battery for your tactical equipment, such as ballistic computers, scopes, and laser rangefinders, make sure you choose a product that can withstand extreme temperatures. For example, any CR123A battery that can work in -20 degrees and 40 degrees Celsius will get the job done.


You want a CR123A battery for the high performance of your device. Some factors that determine the optimal performance of the best CR123A battery are resistance to low and high temperatures, long battery age, and low self-discharge rate. All products mentioned in our review can withstand extreme temperatures between -40 and 140 degrees Fahrenheit.

Lightweight & Compact

Make sure you choose a lightweight and compact CR123A battery for your device. The standard size is about 34 mm in length and 16.5 mm in diameter. Compared to AA batteries that are less compact and have weight, CR123A batteries reviewed in this post are lightweight and durable. Also, look for the battery’s milliamp power and capacity of energy.


If you are buying CR123A batteries for electronic devices and applications like children’s toys and music players, it is important to look for safety features. For example, you can choose a battery that has internal PTC protection because it is safe for usage, even for kids.

Environment Friendly

If you are an environmental enthusiast and want to prevent waste, you should choose rechargeable CR123A batteries. Everyone knows that non-rechargeable batteries are thrown into the landfill, which means the scrap material will end up in our freshwater streams, rivers, and oceans affecting the aquatic climate.


CR123A batteries are available on the market for different prices. Some are expensive and others are affordable. Remember, an expensive battery does not always mean a high-end product that will give you greater performance. So, make sure you choose a product that best fits your needs and budget.
