In terms of their specs, all 123As have the same basic capabilities. Some devices will only work properly with either one of the two, so check the specifications on your device first before switching out. Also, the dimensions may be slightly different. It won’t damage your device if you do however, a rechargeable and non rechargeable batteries may have different voltages and capacities. Can I Use Rechargeable and Non-Rechargeable CR123A Batteries Interchangeably? Some manufacturers simply omit the A at the end. 123A stands for one battery that’s two-thirds the size of a standard A battery. The numbers that follow describe the size of the battery. The C denotes Lithium, and R means the batteries are round. The prefix CR is used by the International Electrotechnical Commission (IEC) to show that the battery uses lithium chemistry, specifically LiMnO2 (Lithium-Ion Manganese Oxide). Frequently Asked Questions What does the CR stand for? The difference in dimensions is so insignificant that both batteries can be used interchangeably in all devices. In fact, each manufacturer uses a different designation for the same kind of battery. When you compare their functionality, performance, lifespan and chemistry, the two are essentially one and the same thing.īoth batteries can support high performance devices, including those that require occasional discharges of high power output like digital cameras with flashes and high tech LED torches. It’s safe to say the only major difference between the two is the letter A. So, what's the final verdict? Are CR123 and CR123A batteries the Same?
Moreover, the high voltage can damage devices.īoth 123s and 123As come with PTC (Pressure, Temperature, Current) protection which disconnects the circuit if the current gets too high. Lithium can be a dangerous chemical, especially if it comes into contact with the skin. Wh per kg or litre measures the battery energy per unit of mass or volume respectively. Note: Wh (watt-hour) is a unit that measures the energy density of the battery. The chemical system works in the exact same way, giving a high energy density per mass (280 Wh/kg) and per volume (580 Wh/litre). The cathode (positive terminal) is made of heat-treated manganese dioxide on both types of cells. Chemistryīoth types of batteries use a lithium-based salt as an electrolyte with a Lithium and Manganese dioxide ( LiMnO2) chemical system. There is typically no significant difference between the voltage on the two battery types. In simple terms, both cells have a high potential to push electric current through the device, especially given their small size. Their standard loaded voltage typically ranges from 2 to 2.5 volts. For example, they can last for up to five years in an alarm system.īoth standard 123s and 123As come with a nominal voltage of 3 volts. The exact life span depends on the gadget and the manufacturer. When using them in your devices, they are both long lasting. Life Spanīoth batteries have a similar shelf life of up to 10 years before use when stored at a temperature of less than 60☌ You can get 6V from two CR123’s that cover a way shorter configuration than 3V from two AAs. The dimensions are usually slightly different with each manufacturer, making it hard to tell the two apart.Ĭompared to alkaline AA batteries (average length of 44 mm), they are both significantly shorter but give twice as much voltage. However, the difference is not more than 0.55 mm in either direction. Their small size relative to the power they give makes them both ideal picks for small devices that use lots of power, like high output LED lights.ġ23s are generally longer and thinner than 123As. Sizeīoth CR123 and CR123A batteries are compact and designed to pack a punch. Is there really any difference between the two lithium batteries? Let’s take a look at a few metrics for comparison. Most brands of CR123s can operate at ranges between 1,000 mA & 2,000mA of continuous current and up to 3,000 mA pulse current.ĬR123 vs. Their power capacity typically ranges between 1,500 mAh (milliampere hour) and 2,500mAh. They’re designed for use in small gadgets like alarms, flashlights, cameras and other household electronics. Let's dig deeper and try to spot the difference between a CR123 and aĬR123s are small, 3V high-powered lithium batteries. Can I Use Rechargeable and Non-Rechargeable CR123A Batteries Interchangeably?ĬR123 and CR123A batteries are lithium-based batteries that work great for small–high output devices like cameras, light meters, smart home devices, high tech torches, tactical equipment and other battery-powered devices.Are CR123 and CR123A batteries the Same?.
