In the world of flashlights, there are many different battery types being used. You have probably heard flashlight fanatics throw around crazy terms like CR123A, 26650, 18650, or D-Cell. What the heck does all this babble mean? Don't worry, we'll explain.
First, it's important to note that the two major battery types most often used are Alkaline batteries and Lithium batteries. Both have their fair share of advantages and disadvantages.
ALKALINE - We are all familiar with Alkaline batteries. These are your traditional AA, AAA, 9-Volt, C Cell, and D Cell batteries. These are the same batteries used in remote controls, smoke alarms, and a myriad of other low voltage electronics. Alkaline batteries are great - they are cheap, durable, and safe. You can find Alkaline batteries being used in almost every entry level flashlight and even in some mid-range flashlights. However, due to the low voltage of alkaline batteries (1.2v - 1.5v), they are not too useful for powering high output flashlights.
To put it in perspective, a standard AAA battery only has a voltage of 1.2v whereas a standard Lithium-Ion battery has a voltage of 3.7v. Now, it is possible to run alkaline batteries linearly to achieve a greater voltage; however, this quickly becomes inefficient when you begin to approach more powerful flashlights. Have you guys seen how big those store brand 1000 lumen flashlights are? They need to be that big in order to accommodate all the alkaline batteries.
LITHIUM - The other battery type is known as Lithium. In this particular example, we'll be reviewing both Lithium-Ion and Lithium batteries. These batteries are considered to be the grand daddy of power sources in the flashlight world. They are small, efficient, and can power all of your favorite flashlights. However, there is an important distinction between the two battery types.
Non-Rechargeable: The Non-Rechargeable Lithium batteries include a model of battery called CR123A. These are 3V Lithium batteries available for purchase at almost any convenience store and are used exclusively by some brands like Streamlight. They are also found in some digital cameras (and are sometimes referred to as camera batteries). These are great little batteries and can definitely provide the necessary power for some higher end flashlights. However, they can not be recharged and need to be disposed of once drained. They retail for approximately $3-$7 each (depending where you buy them) and have a voltage of 3v. While this still isn't as good as the 3.7v found in rechargeable Lithium-Ions, it's light years ahead of the 1.2v-1.5v found in alkaline batteries. The picture below shows two CR123A Lithium batteries used in our TakLite Elite LED Flashlight.
Rechargeable: The other variation of Lithium batteries are Lithium-Ion - also known as the rechargeable kind. These include models like 14500, 16340, 18650, 26650, and so on. These numbers essentially refer to the size of the battery. In the context of flashlights, size 18650 seems to be the most popular and also the one we use in our TakLite flashlights. These batteries are great because they can be recharged and will last the user well over two years before they need replacing. From a price perspective, a single 18650 battery can cost approximately $10 whereas a single non-rechargeable CR123A battery can cost anywhere from $3-$7. It simply makes more sense to use the rechargeable kind. In the picture below, you can see our own TakLite 18650 Lithium-Ion battery being used with the TakLite Elite LED Flashlight.
Fun Fact: Did you know - these are the exact same batteries used in laptop battery packs and electric cars? Just take a look at the picture below. Look familiar?
We are proud to introduce three new additions to the TakLite product lineup: the Eliminator, Elite, and Micro. These three flashlights are all part of our second generation product line which include much sought after features like waterproof frames, drop resistance, and programmable memory. For a quick overview of the new products, please read the guide below:
TakLite Micro - The Micro is a very small flashlight. It measures in at exactly 7.62cm (3 inches) and is comparable to the Olight S10R Baton. However, unlike the Baton, the Micro has a 50% greater lumen output (620 lumens) and is completely waterproof. The Micro operates using either a rechargeable RCR123A battery or a standard RC123A battery which is available for purchase at any convenience store. The Micro's small size makes it a great addition to any EDC or household. Click here to view more information about the new TakLite Micro.
TakLite Elite - The Elite is a mid-sized flashlight with an 800 true lumen output. Furthermore, the Elite's beam pattern has been redesigned to maximize intensity. Like the Micro, the Elite is also completely waterproof and drop resistant (up to 2 meters). The Elite can operate using either a rechargeable 18650 Lithium-Ion battery or two RC123A batteries. The Elite's modest size makes it a great tool for on-the-job applications. Thanks to the Elite's power efficiency, the Elite can be comfortably used by all blue collar workers (electrician, construction worker, plumber, contractor, etc...) without fear of needing a recharge.

TakLite Eliminator - The Eliminator is the grand daddy of our lineup. It is the biggest (measuring in at just under 7 inches) and also the brightest with a true lumen output of 980+. We have also ramped up the beam intensity on the Eliminator to an impressive 144,000+ candlepower. The Eliminator is the only flashlight we sell with a holster -- making it the perfect companion for law enforcement, military, security officers, or anyone looking to secure their flashlight. Furthermore, the Eliminator's 1 inch diameter makes it compatible with any standardized rail mount.
We are genuinely excited about the release of these new flashlights and strongly encourage our customers to provide feedback. We are passionate about the value our flashlights provide and are constantly striving to improve.
