If you have never experienced a lithium flashlight, you are probably wondering what the big differences are to the alkaline powered lights that you are used to. You probably have flashlights right now that are powered by AA, AAA, C, or D-cells–not a 123-lithium battery.
Why buy a lithium-powered flashlight? Here is why:
Most lithium flashlights run on somewhere between one and four 3.0v CR123A lithium batteries. The advantages to using these short and fat little batteries to power a light are numerous.
Unlike alkaline batteries, a 123 lithium battery has a 10 year shelf life and is capable of withstanding much colder temperatures. This is great for emergency use or flashlights that are stashed away in your vehicle.
Probably the single biggest advantage to a lithium flashlight though, is it’s ability to shine brighter (due to its higher voltage) and with greater consistency (due to it’s Li-Ion chemistry) over the life of the battery. As an added bonus, these benefits are often times in a smaller and lighter flashlight too.
Some popular brands of lithium flashlights include Surefire, Streamlight, and Fenix.
