![]() The CR123A is an excellent battery cell for home security systems, flashlights, cameras, military equipment, and medical gadgets. This difference is only minor and hardly noticeable when used in the gadgets. The CR123A has 16g of weight, whereas the CR123 weighs 16.5g. Naturally, everyone wants a lightweight battery to put less pressure on the gadgets and use them efficiently. When it comes to small devices, the weight of the batteries matters greatly. For instance, they provide high energy density per volume and per mass at 580 Wh/liter and 280 Wh/kg, respectively. On the other hand, the cathode generally compromises heat-treated Manganese dioxide.īoth cell systems work the same way, given the similar chemical structure. Chemistryīoth cells contain Manganese dioxide and Lithium and feature a Lithium-based salt as their electrolyte. This feature disconnects the circuit automatically during high currents. The CR123 and CR123As include PTC (Pressure, Temperature, Current) protection. Fortunately, CR123s and CR123As do not compromise safety.Īlthough Lithium is an incredibly hazardous material when it comes in contact with human skin and high voltage can damage gadgets, both batteries come with specialized protection. Of course, they want to protect their electronic gadgets and keep them from unexpected damage. Many buyers check the cells for the safety of their devices. So, it wouldn’t be wrong to say that there is no difference between their voltages. Simply put, both the batteries are powerful enough to provide high voltage to any device. Their standard loaded voltage, however, is somewhere between 2-2.5V. Voltageīoth 123A and 123 batteries have a nominal voltage of 3V. For instance, you can get 3V from two AA batteries but 6V from two CR123s. However, their voltage is twice as much as the former. If you compare the two batteries with alkaline AA batteries, they are smaller. The slight difference is usually challenging to spot, and you won’t be able to tell them apart. But the difference is only minor, with 0.55 mm for both directions. ![]() Yes, 123s have a thinner and longer profile than 123As. Their compact sizes make them ideal for use in small devices that need more power – consider LED flashlights. Both the batteries are small and manufactured to provide high energy. Large size does not always indicate high voltage and battery performance, and the CR123s are proof. Note that the average shelf life may vary slightly depending on the device you’ll power with these batteries and the manufacturer.įor example, the lifespan may be drastically reduced when using these batteries in an alarm system – they may last up to 5 years. ![]() Nonetheless, they must be stored at a temperature below 60C. So, what about the CR123s and CR123As?īoth batteries have the same lifespan of up to 10 years. While the average shelf life can be distinct because of the battery type, it also differs per the manufacturer.įor instance, a battery from a specific brand may last longer than the one you purchase from another brand. Manufacturers design them differently, and individuals utilize them to power various devices.Īs such, the lifespan of batteries varies significantly. Numerous high and low-voltage batteries are available on the market. Here’s a quick look into the features of the CR123 and CR123A batteries to determine what stands true. It isn’t uncommon to think that the two batteries differ in functionality because they have been named differently. The presence of the letter A has caused serious confusion for the buyers. CR123 VS CR123A Batteries: What’s the Difference? Again, the mAh rating means they can power a 100 mA device for 30 hours. Most of these batteries function at 3,000 mAh of pulse rate and 2,000 mAh of consistent power. These batteries are generally 17mm in diameter and 33.4 mm in length and weigh around 16 grams. It works excellent for powering small appliances that require high energy – think digital cameras, LED torches, military-grade technologies, medical devices, security alarms, home automation, etc. The CR123A is a small high-voltage battery. For instance, how much energy a battery can provide and how long it will last. On a side note, mAh stands for Milliampere hours that determine the power capacity of a battery. Note that the mAh batteries are rated for powering 100 mA (milliamperes) devices for up to 30 hours. However, the CR123s of most manufacturers can function at 2,000 mAh of consistent current and maintain a 3,000 mAh pulse current. The power capacity of these Lithium-based batteries is between 1500 mAh and 2,500 mAh. People typically use it in small gadgets like flashlights, alarms, watches, and other everyday electronics. The CR123 is a compact and high-powered Lithium battery. 11 Closing Notes What Is a CR123 Battery?
