CR123 CR123A Batteries - Uses and Considerations

Thank you for joining us today for another Fenix-Store.com Blog. Today we will be discussing CR123A Batteries, how they should be used and what are some of the products that use them. First, What is a CR123 battery? The CR123A battery comes in a non-rechargeable and rechargeable version. It replaces many common batteries including the BR2/3A, KI23LA, L123A, VL123A, and 5018LC. There are many brands of CR123 batteries, some of the most common brands are Duracell, Energizer, Tenergy, and Panasonic. Fenix-store.com sells two o-f these most common brands Tenergy and Panasonic. The specific model is the Tenergy Propel CR123A 3V 1500mAH with PTC protection Lithium battery. On the other hand, we also have the Panasonic CR123A Lithium battery 3V 1550mAH. 
 
Some of the most common uses of the Tenergy or Panasonic CR123 Batteries are for Flashlights, Photo Cameras, Light meters, and Photo equipment. Each one fo these batteries weighs about 16 grams. Dimensions are 17mm in Diameter by 34.5mm in height. the Tenergy CR123A battery has PTC high current discharge protection up to 5 Amps, which will regulate pressure, temperature, and current. Tenergy CR123A batteries have a shelf life of 10 years. These do not replace C batteries, CR123A batteries are 3V in comparison to the 1.5 volts of the C battery, they are also much smaller in size. As we had mentioned before one of the most common uses for these batteries are for high-powered LED flashlights, specifically the Fenix Brand Flashlights. 
 
There are many things to consider when purchasing devices that take CR123 batteries. Brand, mAH, Volts, and compatibility are all things to consider. If you purchase CR123A batteries to use in a Fenix flashlight please consider that Fenix flashlight does not take the rechargeable version fo the CR123A batteries. Rechargeable CR123 batteries also known as RCR123 are equivalent to a 16340 battery, and they are made differently and have different voltage, the most common being 3.7 - 4.2 volts. RCR123 also have a different chemistry, 
for example, IMr, LiCo, and Life4po. It is a good idea to read your user manual thoroughly and make sure that your product can accept RCR123, but in the right environment, these can be used often. 
 
Why will RCR123 not work on most LED Flashlights? RCR123 batteries will not work on most LED flashlight for one main reason: Voltage! Most LED flashlight require between 3 to 3.7 volts to operate, an RCR123 is usually between 3.7 to 4.2 Volts. When you place an RCR123 in a LED flashlight the circuit that controls the LED won't be able to regulate because of the high voltage, this can cause the LED to overheat. This is why it is important to use caution when using RCR123's. It is safe to say that regular CR123's will give you about 50% longer runtime but without the option of recharging them. 
 
We recommend keeping CR123A's handy, especially if you like to travel, hike, run, or bike. Theses are the perfect batteries for outdoor situations. As always if you ever have any questions regarding batteries please feel free to contact us at 1-800-616-1326. Have a great day.
