The main chemical of the battery means Lithium is a dangerous chemical. As CR123 & CR123A are both high-capacity batteries, their high voltage can damage devices.NOTE: Wh (watt-hour) is a unit for measuring the energy density in a battery. The whole chemical reaction works in the same way in both batteries, which provides high-capacity energy density 280 Wh/kg (per mass) and 580 Wh/liter (per volume) The positive terminal or cathode is made of Manganese Dioxide. In these battery cells generally, the electrolyte is made with Lithium based salt-like “Lithium and Manganese dioxide (LiMnO2)”. ChemistryĬR123 and CR123A both are Lithium-based batteries. These two types of batteries can supply high electricity through a small device. From the specifications, we’ve known that CR123 & CR123A have a nominal voltage of 3V and their standard voltage is 2V approximately. There isn’t much difference in voltage between the two batteries. Before use, both the batteries have the same life span of up to 10 years at a temperature of less than 60☌.īoth the batteries are long-lasting though their life shelf varies from different applications of different devices.įor example, in alarm system devices these batteries last up to 5 years, and for the soldier’s weapon light which requires more energy generally lasts for less than a month. The actual life span of the battery depends upon the devices and manufacturers. The CR123 is generally longer and also thinner than CR123A. Main Differences between CR123A vs CR123 Vattery Sizeīoth CR123 and CR123A batteries are small in size and portable. For its small size, it is used in small wireless devices like digital cameras with flashes and high-tech LED torches, etc. Its application area is almost the same as CR123A. Specifications of CR123 battery: Classification Lithium Chemistry Lithium Manganese Dioxide Nominal Voltage 3V Standard Voltage 2V Capacity 2000 mAh Weight 16.5 g Height 34 mm Width 16.5 mm Operating temperature -20☌-70☌ Where it is used? It is also a high-power Lithium-based cylindrical battery extensively used in security alarm systems. What is a CR123 battery?Īs earlier we have known that CR123 is no different than a CR123A battery without a few specifications. Most popularly used in PIR (Passive Infrared) sensor devices like- security alarm, wireless security, home automation, smoke detector, illumination equipment, tactical equipment, etc. This battery is used in various applications- from medical devices to military-grade technology. Specifications of CR123A batteries: Classification Lithium Nominal voltage 3.2-3.3 Volts Standard voltage 2-2.5 Volts Capacity (Lithium) 1550 mAh (approximately) Operating Temperature -20☌-75☌ Height 34.2mm Width (diameter) 17.00 mm Weight 16g chemistry Lithium Manganese Dioxide Where it is used?įor its high capacity and long lifetime, it is very popular and for this sometimes it becomes out of stock in the market. It is a lithium-based cylindrical or can-shaped battery and provides high capacity and long life. Simply CR123A batteries are 123A batteries where 123A batteries are referred to as “one battery that’s two-thirds the size of a standard A battery.”
