Just like the lamp and the switch button, a battery is an essential component in the life of a flashlight. Without the battery, a flashlight will not have a power source which means that the flashlight would not work without a battery.
A battery could be called the most important part of a flashlight and it is essential to know how the battery works in a flashlight and how to insert batteries into different flashlights.
This article shed light on the procedure of putting batteries in a flashlight as well as how the battery ends up giving us light from that flashlight.
How to Put Batteries in a Flashlight?
Putting batteries into a flashlight is a very easy task and as long as the steps are followed there should be no problems with the functioning of the flashlight.
In a Maglite flashlight, there is a feature called the twist-off tail cap that has the function of holding the batteries in their place.
There are several steps to be followed which would ensure that the batteries are inserted in the right way.
Steps for Putting the Batteries in a Flashlight:
- The first step is to twist the tail cap in a counterclockwise direction so that the tail cap is pulling away from the flashlight. In case a battery already exists in the flashlight it can be retrieved.
- The second step is going to be inserting the new battery making sure that the ends that are pointed are facing the light. The number of batteries requires is mostly mentioned on the flashlight packaging. In case there is nothing mentioned on the packaging, the model could be searched on the internet for more information.
- Once the batteries are inserted, we twist the cap back on as far as it can move. The flashlight can then be twisted on or off to make it work. Maglite flashlights also come with rechargeable batteries and adjustable beam intensity.
- Unlike the Maglite flashlights, the Pelican L1 and the Element K2 flashlights have a different systems. These flashlights use alkaline coin cells or more commonly known as watch batteries.
- The procedure of changing or removing batteries is very simple; you remove the chamber, insert the cells and slide the chamber back into the flashlight. First of all, you unscrew the flashlight and retrieve the chamber. You then make note of how the previous batteries are arranged.
In case there are no previous batteries, one can align the cells in such a way that all the positive sides (the side of the cell with a + sign) face in the same direction. The only difference is going to be for the Element flashlight which uses 3 AAA batteries in the place of coin batteries.
The flashlight can be screwed again until it stops twisting after which the light would be fully functional again. You can click the switch on to check if it works. In case the cells are not working, check the placement of the cell and make sure they are properly in place.
How do Batteries Work in a Flashlight?
As important as it is to know the adjustment of batteries in a flashlight, it is even more important to know how it works. When the batteries are placed in a flashlight, and it is switched on, there is a connection between the contact strips which allows the flow of electricity through the circuit.
Being the source of the electricity, the batteries generate it and it travels between the negative and positive electrodes. The cell is placed on a spring that is adjoining a contact strip. These strips connect the entire body of the flashlight right up to one of the sides of the switch.
With one side of the contact strips connected to the switch and the other connected to the bulb, the loop of the circuit is completed and the flashlight is operational. Once functional, the filament lamp or the LED lamp glows and provides the light that emerges from the flashlight.
Once the light emits, the reflector would reflect the light and redirect the beam of light producing a steady beam which is the final product of this whole procedure. Apart from these components, a lens is also placed on top of the lamp to protect the fragile glass form of the lamp and to enhance the quality of the filtered light.
If the switch is turned off, the contact between the switch through the contact strip and the bulb is disconnected, and so is the flow of electricity. Without the loop is complete, the light turns off and so does the flashlight.
Frequently Asked Questions (FAQs)
What are the Most Common Types of Batteries Used in a Flashlight?
A: In this article, there are three kinds of batteries mentioned; the 3 AAA batteries, the coin cells and watch batteries. There are many more types of cells but you should buy the ones which are compatible with your flashlight model.
How to Know if the Batteries are Due for Replacement?
A: One great indication is if the light dims or the flashlight doesn’t turn on at all. This means that the cells are no longer strong enough to provide the same amount of electric power to the circuit.
Why Wouldn’t the Flashlight Work?
There can be many reasons for the flashlight not working such as weak cells, a snag in the circuit, damage to contact strips, and even damage to the lamp. The wrong placement of cells can also be a probable cause if your flashlight is not working.
Conclusion
The procedure of inserting batteries into a flashlight is a simple one. All you have to do is follow the instructions and make sure that the batteries and facing the right way. This is essential for the circuit to be completed and the flashlight to work. Apart from this, the steps are very easy to follow and anyone can do it.
As long as the batteries are compatible with the model of your flashlight and the cells work, the flashlight should also work.
