ĭue to safety concerns, producers of RCR123A batteries often distribute them to consumers with only a 50% charge and then ask that the batteries be fully charged before first use. Be sure to get as much information as you can about such products before investing in them.Īs noted earlier, CR123A batteries have a significantly lower nominal voltage than RCR123A batteries. However, some products claim to be capable of both high capacity and high drain. Usually, the higher the capacity of an RCR123A battery, the lower its maximum drain. Some of these differences are highlighted below.ĬR123A batteries have a much higher maximum capacity than RCR123A batteries. However, apart from the former being usually non-rechargeable and the latter being rechargeable, there are a number of other differences between both battery types. Some features to look out for when searching for a high-quality charger include built-in voltage/overcharge protection, a thermal sensor, capacity for battery testing as well as both charge and recharge capabilities, if possible.Īs noted above, both CR123A and RCR123A are mostly cylindrical batteries with lithium chemistries. Because of this, care should be taken to ensure they are charged with high-quality chargers to avoid unpleasant consequences such as fire incidents or battery explosions that can arise due to overcharging or overheating. RCR123A and other lithium chemistry batteries are often high-energy but lightweight in nature. Like CR123A batteries, RCR123A chemistries can also provide sufficient power for a variety of products, including high drain devices like: They can be recharged with li-ion smart chargers. The 17340 version has a diameter of 17mm and a height of 34mm. A large variety of 16340 batteries have a lithium carbon-oxide chemistry. Many RCR123A batteries have a diameter of 16mm and a height of 34mm and are therefore referred to as 16340 batteries. RCR123A batteries are regarded as rechargeable versions of the mostly non-rechargeable CR123A batteries though their higher voltage means that users should be careful to determine whether their device will be compatible with such an increased voltage. However, they have a higher nominal voltage capacity that ranges between 3.6-3.7 volts. Like their CR123A counterparts, the rechargeable CR123A or RCR123A batteries are also mostly cylindrical lithium-based battery chemistries used in several applications. However, with continuous innovation, usage scope has since expanded to include a lot of other high drain products such as: The earliest CR123A battery was meant to be used only on cameras because its high current capacity helps ensure sufficient power for a camera’s flash and motor drive. CR123A batteries are usually non-rechargeable. It is not compulsory that the letter A must always be included. 123A means one battery that has two-thirds the size of a standard A battery. Specifically, the C represents Chemistry while the R is short for Round. The International Electrochemical Commission uses the letters CR to indicate the lithium chemistry of CR123A batteries. They are easy to store and have a shelf life of up to 10 years. They usually have a nominal voltage of 3V, a height, and diameter that should be in the range of 34mmx17mm, and a nominal capacity that can reach 1500mAh and more. The usually button-top CR123A batteries are designed to be extremely light and can easily cope with huge discharge currents.
