Different Types of batteries for flashlights

Welcome to Today we will be discussing Batteries and how the many types of batteries can be used in many of our Fenix flashlights and headlamps. Because of the variations available through the, there are many different options available for what types of batteries you would like to use. Whether you are working with a headlamp, EDC flashlight or even a tactical flashlight, Fenix store has all these options available for you. In many cases, we have many different types of batteries available in each of these categories. The most commonly used battery that we carry is the 18650 battery. The reason is simple, it offers the most power for a compact size, however, we have many other batteries you can use. For example, the EDC line or everyday carry line has the LD12 or the LD22, both of these flashlights would use AA batteries.

he main benefit of using AA batteries is that it allows for the flashlight to keep a very slim or low profile, compared to flashlights that use 18650 batteries and this would translate to the size of the flashlight. Something like the PD35 might be more powerful than the LD22 the PD35 will, of course, be longer and wider because of the use of the 18650 batteries as compared to AA batteries. We do have several options that use AAA batteries. These are the options that are great for keychain flashlights or even pocket flashlights that you carry with you in case of an emergency. For example the Fenix E05 or the new LD02 V2.0. Both of these flashlights would use AAA batteries and they also include a tail switch functionality plus UV lighting.

When we move up to flashlights that use 18650 batteries we can get more power from them. The Fenix PD35 TAC which is our top seller that you can find on uses either two CR123 batteries or you can use one single 18650 battery, we recommend the Fenix brand. With a single 18650, it will give you 1000 lumens of output and it can be considered both a tactical flashlight for EDC flashlight because of its low profile. Other flashlights in this category include the PD35 V2.0, Fenix UC35 V2.0, and the Fenix UC30. The latter being the most compact of the 18650 flashlights we have available. The power that comes from 18650 batteries translates to a very short and compact EDC flashlight with a simple single rear power switch and a single side switch for brightness level control. The Fenix UC30 is also the least expensive flashlight at 1000 lumens with an included battery.

Currently, 1000 lumens is the max output you can get from a single 18650 battery. However by increasing the number of batteries to even just two 18650 batteries you can increase the power or output of the flashlight. One example is the Fenix TK35UE, which uses two 18650 and has a max output of 3200 lumens. This is an incredible output for this flashlight, while also having a unique body design making It a top seller. The TK35UE has the orange peel reflector, which makes it a very nice flood light. Similarly, you also have the TK47UE and TK47 which both use two 18650 batteries. The only difference is the reflector, one with an orange peel reflector and the other with a focused reflector for long distance visibility. If you increase the number of 18650 batteries to four you get even more power. One example is the TK75 which has 5100 lumens from four 18650 batteries. This all-new TK75 has the longest visibility of all the flashlights available at

Last, let's discuss some of the options that include built-in rechargeable batteries. These batteries cannot be removed. Some of these lights include the Fenix BC30R bike light or the CL26R camping lantern and many of the new Fenix headlamps like the HL40R. All have built-in rechargeable batteries. The benefit of built-in rechargeable batteries is that you never have to worry about losing or misplacing the batteries. All these lights have a built-in charging functionality, you don't have to worry about buying a separate charge also. They all charge via a micro USB port on the light or headlamp. They also provide a very good amount of lumen output for the size.

This wraps up a general overview of the batteries offered here at We welcome you to browse the website or give us a call if you have any questions about batteries or about any Fenix flashlight like chargers that we offer.
