Rechargeable Protected 3.6 volt CR123A Li-ion Battery

Lithium Ion protected batteries reach 4.2 volts when fully charged, after a few minutes of operation they will drop to approximately 3.7 volts (this is called the nominal voltage of the cell.) These cells have an internal circuit board (PCB) to protect against over charge, over discharge, and over current draw. Current limits on these cells are about 2C or 1.1 amp.

Measured Capacity: 500mAh at 300mA discharge. This is a true measurement as seen in the plot included in the product images and good performance for a rechargeable CR123. 

About Capacity: At e-lectronics.net we strive to source good products and then we measure and report actual capacities measured at applicable current loading. Don't be fooled, most all Li-ion cells are over rated by the manufacturers. You will see others marketing rechargeable CR123 batteries rated as high as 1000mAh which is simply false advertising, Li-ion technology is not currently capable of producing capacities that high in a 16340 CR123 battery. At e-lectronics.net we tell it like it is! 

NOTE: We sell 4 different rechargeable CR123 batteries; chargers for each are specific and can not be interchanged. Please assure that your electronic device such as flashlight is designed for use with 3.7 volt cells, if yours is not, see our 3.0 volt rechargeable CR123A batteries. 

Charging requirements: Only charge these batteries in an approved Li-ion battery charger with termination voltage of 4.1 - 4.2 volts at a charge rate of ~350mA; do not exceed 500mA.
