How Torches Work

The mechanics of a torch seem so easy that’s it’s often overlooked. Here’s a step-by-step explanation of how your everyday battery powered torch works:

1 – This part of the torch is called a case. It is the tube that encompasses the parts of the torch.

2 – This part of the torch is the contact throughout the torch. It is a very thin spring or strip of metal that runs through the torch, electronically connecting the various parts of the torch. This parts conduct electricity and completing the circuit.

3 – This is the switch of the torch. The flow of electricity is activated when you switch the torch on, turning the light on. The flow of electricity is interrupted when the switch is turned off, turning off the light.

4 – This part of the torch is called a reflector. It’s the plastic part, coated with a shiny aluminum layer that sits around the lamp and transmits the light rays from the lamp to allow a steady light beam.

5 – This part of the torch is called the lamp. It is known as the light source in a torch. In most torches, the lamp is either an incandescent bulb or a solid-state bulb, also known as an LED.

6 – This part of the torch is known as the lens. It is the clear, plastic part you see on the front of the torch that protects the lamp, since the lamp is made of glass and may easily be broken.

7 – This part of the torch is where batteries are inserted. When activated correctly, the batteries are the power source for your torch.


Now you ask, how do all these parts work together?


When the switch of a torch is on, it allows contact between two contact strips, which begin a flow of electricity. This power is from the battery. The contact strip runs down the length of the battery case and connects with one side of the switch. There is another flat contact strip on the other side of the switch, which runs to the lamp, providing an electrical connection. Another part is connected to the lamp that connects with the positive electrode of the top battery, completing the circuit of the lamp.

When activated by electricity, the LED in the lamp begins to glow, producing light. This light reflects off of the reflector that is positioned around the lamp. The reflector transmits the light rays from the lamp, creating a steady beam of light, which is the light you see emitting from the torch. A clear lens covers the lamp on your torch so that the glass on the lamp does not get broken.

When the torch switch is then pushed off, the two contact strips are physically moved apart and the path for the electrical current is interrupted, thus ending the production of light, and turning your torch off.

All parts in the torch must be connected as stated in this article for it to work correctly.

How to Care for Your Torch

There are do’s and don’ts with everything we do. From the smallest tasks to the bigger, more tedious tasks. When buying tools, it’s much easier to be made aware about the do’s and don’ts of handling your products, because a cute little instruction manual is always in the back of the box whenever you need it. But they’re rarely used. For battery powered tools such as torches, owners often forget that maintenance and handling your tools are important. Here are some do’s and don’ts of handling your toolbox torches.




Torches are much more important than you think, get yours today, and you’ll never be stuck in the dark ever again!


Chargers: Going Completely Mobile?

Chargers Going Completely Mobile

Chargers: Going Completely Mobile?

Mobile devices are not much use when they run out of juice. This is not a problem, each of your mobile devices do come with a charger. It is typically a standard outlet charger that only fits that one piece of equipment. So you have got a charger for your phone, your laptop, your music player and your portable DVD player. They all have to be plugged in for several hours to charge up, and a half-dozen chargers can get overwhelming.

Luckily, there are a lot more options these days when it comes to juicing up. One good space-saving choice is the worldwide/universal charger. This is a charger with numerous adapters, so it can charge all of your different mobile devices. Some of them can even charge several devices concurrently, so you only need one outlet to do the job.

Another option is the USB charger. With this type, you do not even need an outlet, the charger draws power from your computer’s USB port. So if you are sitting at a coffee shop on the Wi-Fi with a fully juiced laptop and a dead cell phone, you can simply use one to power the other. But what about when your laptop is out of battery power, too? And what if there is no wall outlet at all? Then what? Here is what:

The electronics industry is making big steps toward unravelling this issue, which is really the last remaining impediment to complete mobility within the established world. Several different groups, including Sony and MTI Micro, are in the final stages of emerging a fuel-cell charger, which generates its own power through a chemical reaction. There are solar-powered and wind-powered chargers already on the market, which are less than ideal because they require a specific environmental condition, but they are still useful for outdoors applications.

One last type of charger could kill two birds with one stone. The kinetic-energy charger, which uses motion to produce electricity to power your mobile device, is now available, but there are upgraded versions on the way. These newer kinetic chargers will essentially create enough power to be useful as something more than an innovation. And, as a big side advantage, if they really catch on, they could solve the low-power problem and the obesity problem in one shot.

Batteries have played a significant role in our everyday lives and yet without these batteries being charged we are left unable to work, communicate with others and or even entertain ourselves. So take into consideration the importance of batteries; but, our batteries need chargers so if you are in need of chargers whether it be multi-way chargers or standard consumer type chargers then please do not hesitate to contact Just Batteries for more information.

How Batteries Work

Picture a world where everything that used electricity had to be plugged in. Hearing aids, flashlights, cell phones and other portable devices would be bound to electrical outlets, leaving them awkward to use. Cars could not be started with the simple turn of a key; a persistent cranking would be essential to get the pistons moving. Wires would be strung everywhere, creating a safety hazard and an unappealing mess. Luckily, batteries provide us with a mobile source of power that makes many modern amenities possible.

While there are many diverse types of batteries, the basic concept by which they function remains the same. When a device is linked to a battery, a reaction transpires that creates electrical energy. This is known as an electrochemical reaction. Italian physicist Count Alessandro Volta first learnt this process in 1799 when he made a simple battery from metal plates and brine-soaked cardboard or paper. Since then, scientists have significantly improved upon Volta’s original design to produce batteries made from a variety of materials that come in a mass of different sizes.

Today, batteries are all over the place. Batteries power our watches for months at a time. They keep our telephones and alarm clocks working, even if the electricity goes out. They run our smoke detectors, power drills, electric razors, thermostats, mp3 players, etc. and the list goes on. If you are reading this article on your smartphone or laptop, you may even be using batteries right now. On the other hand, because these portable power packs are so customary, it is very easy to take them for granted.

A lot happens inside a battery when you pop it into your remote control, flashlight or other wire-free device. While the processes by which they create electricity differ to some extent from battery to battery, the basic idea rests the same. When a load completes the circuit between two terminals, the battery creates electricity through a series of electromagnetic reactions between the cathode, anode and electrolyte.

Batteries have been around for quite some time now and have made our lives incredibly easier, think about this, the most used electronic on earth is our cell phones and they all run on batteries, so? So, this means that without batteries we would not have our cell phones wherever we go. If you need any sort of battery then please do not hesitate to contact Just Batteries for more information.

How an Electric Car Battery Works

A car can be a wonderful thing. It takes you wherever you want to go, whenever you want to go there, even if those places aren’t served by public transportation. In fact, a lot of our modern lives would be negatively impacted if we didn’t have cars. Our cars get us to our jobs, grocery stores, schools or just to the mall. But as wonderful as they are to us, they also have some serious downfalls. Two of these downfalls are that they cost so much to maintain and they also pollute our atmosphere with noxious gases.

Air pollution has become a huge problem in many of our urban areas, and with the prices of gasoline at an all time high, the internal combustion engine might soon become a luxury that our society simply cannot afford.

Not many people would advocate giving up their cars all together, but is there not a way that we can have the power and convenience of an automobile without having the pollution and expense caused by burning gasoline? Fortunately for us, there is. Many of us are under the impression that the cars of the future will be powered not by gasoline but by electricity. In fact, these electric cars that are also known as EVs or just electric vehicles, are not so futuristic at all. . . Believe it or not, the electric vehicle has been around since the first half of the 19th century, however, even today in the 21st century, the internal combustion engines are still ruling. So why haven’t electric vehicles caught on?

The heart of an electric vehicle is its battery. Unlike batteries in motor cars, which mainly serve to start the engine and run things like the radio or air conditioner, the battery in an electric car runs everything. The most important aspect is that the battery runs a controller which then runs the electric motor, therefore it needs to be powerful and long-lasting enough to take the driver where they want to go with a minimum of recharging.

Thus, far no reliable, mass-producible batteries have been manufactured that could make an electric car competitive with a gas-powered car. However, this is beginning to change. Electric cars have now become realistic and are expected to start being produced by huge automobile manufacturers.

Purchasing the Perfect Torch and Batteries

Purchasing the Perfect Torch and Batteries

Whence you have been camping, hiking, fishing or just taking the dog out for a walk, as soon as the sun goes down you’ll be in need of a flashlight or torch. Torches and flashlights come in various different forms and this guide may help you in choosing the correct torch or flashlight for your outing.

Battery Powered

Majority torches and flashlights are be powered by normal alkaline batteries. The kind of alkaline battery will mainly depend on the size of the torch or flashlight. Sizable spotlight torches for example will usually use D batteries, whilst the smaller torches or head torches are more likely to use AA or AAA batteries. The more modern torches may use CR123A batteries whilst some head torches will be powered by the smaller flat CR2016 batteries.


Rechargeable torches and flashlights are increasingly favored. A rechargeable torch will be powered by lithium-ion batteries that can be recharged through the plugs in your home/work or in a car with the right adapter. As a rechargeable torch/flashlight needs a power source to recharge, and they have a reduced use time when compared to battery powered torches, they might not be fitting if you intend to use them for an entire evening out camping.

LED Torches

LED lights are low energy bulbs; they are more efficient and cost-effective than standard bulbs which equals to a longer burn time. They are also brighter than traditional bulbs, producing a whiter and brighter light. Cree LED light chips are more efficient still, last longer and are extremely brighter, but the down fall is it produces more heat. Power LED lights are similar to Cree LED lights, a more powerful version of normal LEDs. LED bulbs can also be in different colours.

Gauging the Lifespan of your Batteries

Gauging the Lifespan of your Batteries

Being able to proactively replace batteries before they run out will make your life a lot more convenient, but isn’t always that easy to get right. Firstly, battery products differ in terms of their lifespans, which is further affected by their expectations on performance, and which appliances or devices they are meant to power. So, to give you the tools to be able to better tell when they will be depleted so that you can act in good time, here is some information that will help you understand the life-cycle of the battery.

Measuring the capacity of a battery

Units of battery capacity are generally measured and set out by manufacturers in terms of how much energy it is capable of storing. This can be measured as watt-hours (Wh), kilowatt-hours (kWh), or ampere \-hours (Ahr). The type of measurement depends on the overall capacity of the battery, with Wh measuring smaller capacities and Ahr measuring those with extremely high ones, and can be represented as follows:

1Wh = 1 watt per hour

1kWh = 1 kilowatt per hour

1Ahr – 1 ampere per hour.

Understanding a battery’s life-cycle

Particularly when it comes to recyclable batteries, their lifespan is generally measured in terms of charge and discharge cycles, which is otherwise known as its cycle life. This is measured in terms of how many cycles a battery can reach in terms of charges and discharges, before it falls to below 80% of its original capacity. The number of charge cycles that a battery can support before falling below 80% and becoming noticeably less effective, will of course vary depending on battery types, manufacturers and their application.

Calculating Amp hours

To calculate a required battery life depending on the voltage of the device being powered, one must look at its capacity in terms of amp hours, and see how it is being used. The formula looks like this:

Wattage=Amps x Voltage

So, if we take a 100-Ahr battery, and we plan on using it for 20 hours, we could essentially say that it would be providing 5amps per hour, for the duration of its use. So, for a 12-volt battery, the formula would look like this:

Wattage= 100 amperes x 12 volts

The watt hours would therefore equal 1200, or 1,2kWh.

We now divide the total 1200-watt hours up by the expected operation time which is 20 hours, and find that it operates at 60-watt hours for its duration.
