The CR123 is a lithium manganese dioxide battery that is non-rechargeable. The most common name for the CR123 is CR123A. This battery is used in electronic devices such as cameras, flashlights and radios.
The nominal voltage for the CR123A is 3.0 volts. Nominal voltage refers to the typical terminal voltage of a battery during discharge.
The nominal capacity for this battery is 1400 milliampere hours. Nominal capacity, also called normal capacity, is the total electrical charge in the battery as measured by discharge at a certain current. This measure is equal to the number of amp hours from total charge to cut-off voltage.
Standard Discharge Current
The standard discharge current for the CR123A is 10 milliampere hours. Discharge current refers to the rate at which the electrical charge leaves the battery during the discharge process.
Maximum Continuous Discharge Current
The maximum continuous discharge current for this battery is 1,000 milliampere hours. This is the maximum current at which the battery can be continuously discharged. The manufacturer sets this limit in order to prevent extreme discharge rates that might harm the battery or may diminish the battery’s capacity.
Maximum Pulse Discharge Current
The maximum pulse discharge current is 3,000 milliampere hours. This is the highest current at which the cell can be discharged with pulses of up to thirty seconds. This limit is also set by the manufacturer to prevent potential damage to the battery.
The CR123A measures 33.7 millimeters (plus or minus 0.4 mm) by 16.7 mm (plus or minus 0.3 mm). This battery weighs about 16 grams (0.56 ounces).
The operational temperature range for the CR123A is -40 to +60 degrees Celsius (-40 to 140 degrees Fahrenheit). The temperature at which the battery is operated and stored can affect how quickly the battery discharges.
