storage and shelf life: for safety reasons, RCR123A batteries are manufactured and transported only half-charged and must be fully charged before the first use. Personally, I doubt that such batteries (not just RCR123A) are as reliable as batteries from reputable brands. Note: some RCR123A manufacturers advertise their RCR123A batteries as both "high drain" and "high capacity" batteries (>1000 mAh), but before buying such batteries, be sure to read the reviews of other buyers first. High-capacity RCR123A batteries usually have a lower maximum drain current than RCR123A batteries with lower capacities, but this must be verified for every model. capacity: CR123A batteries feature a capacity of ~1500 mAh, while RCR123A batteries feature a capacity of 500-800 mAh, with most models having a capacity of around 700-750 mAh. Note that 3.3 volts RCR123A batteries feature 0.3 volts higher nominal voltage, and 3.0 volts RCR123A batteries have practically the same voltage as CR123A batteries and can be used in less sensitive devices (if recommended by the device's manufacturer!). output voltage: CR123A batteries have a nominal voltage of 3.0 volts, while RCR123A batteries have a higher voltage (usually 3.6-3.7 volts), and this voltage difference can cause operating issues for sensitive electronic equipment.īefore replacing the CR123A battery with the RCR123A battery, check if your device can be powered with an RCR123A battery. The main differences between CR123A and RCR123A batteries are: Note that rechargeable 3.0 and 3.3 volts batteries are also present on the market. Rechargeable CR123A batteries (or RCR123A batteries) usually have voltage in the 3.6-3.7 range and capacity in the 500-800 mAh range. Non-rechargeable CR123A batteries also tolerate high drain currents, which is very important for high-power devices and for devices that require plenty of power for relatively short periods of time. The shelf life of the best CR123A brands is usually in the 7-10 years range, making these batteries excellent choices for standby devices like EDC flashlights, security devices, digital cameras, military applications, and similar. Non-rechargeable CR123A batteries have a nominal voltage of 3.0 volts and a capacity of around 1500 mAh. Voltage, capacity, and max drain current depend on the CR123A model and chemistry. But, they all are also labeled as 'CR123A'! These batteries are commonly labeled as 'CR123A batteries' (non-rechargeable type) or as 'RCR123A batteries' (rechargeable type), but they also appear with other labels, like CR17345, K123A, RCR16340, VL123A, DL123A, 5018LC, SF123A, EL123AP, 17345, 17340, 16340, etc. That and the fact that many manufacturers come with their 'own' labels lead to slight confusion when picking the right CR123A battery.ĬR123A Batteries - Features and SpecificationsĬR123A batteries are cylindrical batteries, featuring a battery size of 17 mm in diameter and 34.5 mm in height (0.67 x 1.36 inches). Non-Rechargeable Lithium CR123A BatteriesĬR123A batteries are very popular cylindrical lithium batteries, commonly used in various devices like photo cameras, flashlights, security devices, military equipment, etc.ĬR123A batteries come in two major versions: rechargeable and non-rechargeable CR123A batteries, both featuring different voltages, drain currents, capacities, etc. I read somewhere for lights that are intended/anticipated to encounter significant/repetitive shock such as a firearm, companys like Stream light feel rechargable cells are at a higher risk of some damage such as rupturing or leaking over non-rechargeables.Best CR123A Battery - Rechargeable vs. Being able to recharge with common usb power is liberating. And I don't have much worry about leaking cells.īut for handheld and other lights, I have shifted to rechargable 18650s for some time now. The long time between use and knowing the battery should have plenty of juice while it sits away in waiting is comforting. I can attest that I have used ones stored away for 5+ years with no decernable reduction in power or lifespan. I too have got good prices on the Surefires when bought by the dozen at my local LEO store.įor my firearm lights, I prefer the non-rechargables for the lifespan and extremely low self discharge rate of the cr123s in paticular.
