Powerful flashlight 18650 battery

Before getting to know about the 18650 battery, we must first understand what is a LED powerful flashlight and why it’s different.

It is a new type of lighting technology using LED light-emitting diodes as light sources, provides the advantages of power saving, durability, and high brightness.

To be more specific, high-brightness LED flashlight has the advantages of power saving, waterproof, anti-corrosion, explosion-proof, anti-drop, durability, and strong brightness.

This kind of flashlights are often used as long-duration flood light and emergency light source in circumstances such as public security,fire department , petroleum, chemical industry, electric power companies, metallurgy industry, ship industry, railways industry, coal mines, flood control situations, rescue situations, and disaster relief.

The most used LED powerful flashlights are using the 18650 lithium-ion battery:

18650 is pretty much describing the battery itself, 18mm in diameter and 65mm in length. The common AA battery model is called 14500, 14 mm in diameter, and 50 mm long. Generally, 18650 batteries are more popular with general industries, less in civilian use. The most common use of these 18650 batteries are used for laptop batteries and high-end flashlights. But now all the flashlight brand manufacturers have different sizes of it because the additional protective plates and additional protective materials.

1.Batteries of the LED powerful flashlights are also an important part of the flashlight specs. It would be almost accurate that the battery used by the IMALENT LED powerful flashlights basically determines the size and positioning of the flashlight and their capabilities. The power consumption of current LED powerful flashlights are generally not small, from the perspective of economic and environmental protection. IMALENT LED powerful flashlights mostly use 18650 batteries. The most ideal battery choice as a rechargeable lithium-ion battery, which has high energy density, high discharge voltage, it’s all for the best when it comes to budget friendly and environmental protection, etc., these are other various of advantages. The 16340, 17335, 14500, 18650.26650, and other batteries we usually call are the models of these rechargeable lithium-ion batteries.

2.The volume of the 16340 battery used in the LED powerful flashlight is the same as that of the CR123A battery, but the process is different. The energy density of the CR123A can even reach 2.5 times that of the 16340 battery. In addition, its effective storage life is much longer, even up to 10 years. In practical applications, the combined volume of two 16340 (CR123A) aren’t much different from one 18650 battery, many LED flashlight battery compartments are designed to accommodate one 18650 so that one can use a single 18650 battery. It can be powered by 18650 batteries, and can also be powered by two 16340 or CR123A batteries, flexible as it is.

3.The most used IMALENT LED flashlight is the 18650 battery. Its model parameters can be understood as follows: the first two digits represent the diameter of the battery, the third and fourth digits represent the length of the battery, and the unit is mm, and the last 0 means that the battery is a cylindrical battery. The 18650 battery is a cylindrical battery with a diameter of 18mm and a length of 65mm. Its energy density is the largest among the large-scale rechargeable batteries currently available on the market, and the discharge current can also used in a normally powerful flashlight. It can be said that it is the most suitable battery for powering IMALENT LED powerful flashlights. The 14500 is also widely used, and the reason is very simple. Its volume is the same as that of an AA (No. 5) battery, and it can be put into a flashlight using AA batteries. Of course, it needs to be supported by the circuit system. The CR123A battery is a non-rechargeable lithium-ion battery, commonly used in cameras, and its outstanding advantage is its high energy density.

Fourth, IMALENT's LED powerful flashlight. As mentioned earlier, there are many advantages of rechargeable lithium-ion batteries. Although lithium-ion batteries are good, they are a bit troublesome to use. The biggest trouble is that a special charger is required to charge them. It is now recognized that the charging method for rechargeable lithium-ion batteries are to charge the battery with a constant current first and then constant voltage, that is, first charge the battery with a constant current, at this time, the voltage at both ends of the battery will rise, and when the voltage rises to the inflection voltage (4.2V), the voltage will be maintained unchanged, and the current will start to decrease accordingly until the charging current decreases to a certain extent. At this time, the charging process is completed, and the cut-off current is generally 1/10 of the initial charging current, also it might slightly differ from the lad result.

The powerful flashlight is the best of all ordinary flashlights on the market. IMALENT flashlights use 18650, 21700 battery types, etc. Imalent leads the world in powerful flashlights and holds the record as the brightest LED flashlights.
