Energizer CR123A 3V 1500mAh Lithium Button Top Battery
This cell is overwhelmingly the best primary Lithium CR123A battery available, both in terms of maximum capacity and maximum discharge/drain. This is NOT a rechargeable cell - it is only meant to be used until the cut-off voltage of ~2.0V is finally reached and then properly disposed of. It is also NOT a Lithium-ion battery/cell. This cell has the chemistry of Lithium/Manganese Dioxide (Li/MnO2) with a nominal voltage of 3.0 volts with 1,500 mAh in capacity down to 2.0 volts (Rated @ 100 ohms @ 21 degrees Celsius or 70 degrees Fahrenheit). This cell, when fresh, typically has an open circuit voltage (eg. Unloaded Voltage) of 3.20 to 3.25 volts. The maximum constant discharge/drain for this cell is 1.5 amps with up to 3.5 amps for pulsing (eg. flash photography). This cell is the absolute best non-rechargeable primary CR123A battery/cell that you can buy in the market today. This cell is typically used for EDC-sized flashlights, digital camera's, surveillance equipment, and some medical equipment.
