What Are CR123 Batteries?
CR123 batteries are lithium primary batteries that are commonly used in a wide range of devices, including flashlights, cameras, and other electronic devices. They are known for their long shelf life and high energy density, which makes them a popular choice for portable devices that need a lot of power in a small package. The batteries are typically 3 volts and are cylindrical in shape. They are relatively easy to find in stores and are usually sold in packs of two or more. Due to their high energy density, they are used in high-drain devices, such as flashlights, high-performance flashlights and camera strobes. They are also used in emergency and safety devices, such as smoke detectors.
What Are CR123A Batteries?
CR123A batteries are a type of lithium primary battery that are similar to standard CR123 batteries. The main difference between the two is that CR123A batteries are designed to be used in high-temperature environments, whereas standard CR123 batteries are not. These batteries have a higher operating temperature range and are able to maintain their performance in temperatures up to 85°C (185°F). They are also used in devices that have high power requirements and are used in high-drain devices, such as flashlights, high-performance flashlights and camera strobes. They are also used in emergency and safety devices, such as smoke detectors.
Difference between lithium 123 and lithium 123a
Size
Both the CR123 and CR123A batteries are compact and designed to pack a punch. Their small size relative to the power they put out makes them an ideal choice for small devices that consume a lot of power, such as: B. High power LED light. 123s are generally longer and thinner than 123As. However, the difference is less than 0.55 mm in both directions. It’s hard to tell the difference between the two because the dimensions usually vary slightly from manufacturer to manufacturer. Compared to an alkaline AA battery (average length 44mm), both are significantly shorter, but deliver twice the voltage. You can get 6V from two CR123s which covers a much shorter configuration than 3V from two AAs.
Lifespan
Both batteries have a similar shelf life of up to 10 years before use when stored at temperatures below 60°C. Both are durable when used in a device. Exact life expectancy varies by device and manufacturer. For example, it can be used in alarm systems for up to 5 years.
Voltage
Both standard 123s and 123As are rated at 3 volts. Typical charging voltages are usually in the range of 2 to 2.5 volts. Simply put, both cells are more likely to conduct current through the device, especially because of their small size. There is usually not much difference in voltage between the two battery types.
Chemistry
Both types of batteries use lithium-based salts as electrolytes, including lithium and manganese dioxide (LiMnO2) chemistries. In both types of cells, the cathode (positive electrode) consists of heat-treated manganese dioxide. The chemical system works exactly the same, with higher energy densities per mass (280 Wh/kg) and per volume (580 Wh/liter). Note: Wh (Watt-hour) is a unit of measure for battery energy density. Wh per kilogram or liter measures battery energy per unit of mass or volume.
Safety
Lithium can be a dangerous chemical, especially when in contact with skin. In addition, high voltage can damage equipment. Both 123s and 123As he is equipped with PTC (pressure, temperature and current) protection which will cut the circuit if the current gets too high.
