CR123 3.0 Volt RECHARGEABLE Protected Li-ion Battery

600mAh 3 volt nominal output rechargeable CR123 with circuit protection

There are several versions of rechargeable CR123 on the market today each requiring a unique charger which are not generally interchangeable. Use caution when selecting your batteries and chargers.

This unique battery is a Lithium Ion battery with an internal circuit (IC) which regulates the output voltage level. The reason for this is that a standard non rechargeable CR123 (called a primary battery) is 3.0 volts due to its chemical make up and operates under load at about 2.8 volts. Some electronic devices such as flashlights are optimized for this 2.8 battery voltage and can not operate with a standard 3.7v lithium Ion rechargeable battery which is 4.2 volts when freshly charged and gradually drops to a nominal operating voltage of 3.7 volts.

There are several versions of 3.0v rechargeable CR123 batteries on the market today including this one offered by e-lectronics.net, each one is different with unique specifications and they are not interchangeable. None of these are a direct 1 for 1 replacement for a disposable Primary Lithium CR123 although these do work in most applications when a standard Li-ion 3.7v cell is too high of voltage. As seen in the chart below, this cell is approximately .7mm larger in diameter than a primary CR123 which measures 16mm diameter by 34mm long.

The circuit in these RCR123 3.0IC batteries not only regulate voltage output, it also provides protection against min/max voltage and current specifications. Li-ion protected cells are commonly identified by any of the following: PCB (printed circuit board), PCM (power control module), or IC (internal circuit) which are all terms that indicate the cell has an electronic circuit designed to create an open circuit when design specification values of current or voltage are exceeded. This circuit is located at the negative end of the cell with in a small plastic case and concealed by the PVC shrink wrapping. To test the PCB of this cell, place a 1k ohm resistor across the terminals to activate the circuit while measuring voltage with a voltage meter.

Some flashlight models do not work with this cell due to their high initial start up current which is perceived as a short circuit or overload and trips the protection circuit of this battery. This is sometimes over come by several clicks of the power switch which energizes the bulb just long enough to heat it up which raises the resistance of the filament and lowers the current draw. Lights known to exhibit these characteristics are noted in the chart at the bottom of this page.
