Battery Powered Cars - Just Batteries

Battery operated cars

Global warming is a real problem in today’s society. There are millions of tons of CO2 being forced into the atmosphere by motor vehicles, trucks and tractors as well as machinery that runs on fuel. Car companies are trying their utmost to reduce the emissions produced by their motor vehicles to comply with national and international regulations.

Even greater efforts were made to protect the environment and save people some money on fuel, and the hybrid car was born! A hybrid can be defined as any vehicle with more than 1 source of power ie, a fuel consuming engine and an electricity consuming, electric motor. Hybrids still consume fuel and they need to be charged. They still use a standard car engine but they also have an electric motor. Users can experience high km per litre fuel consumption and far less emissions. However, less emissions is not zero emissions.

The most revolutionary battery powered car of the 20th century has to be the Tesla model S. This car can reach 480km on a single charge and it goes from 0 to 100kmph in 5.6 seconds which is amazing for an electric car and it can reach a top speed of around 208kmph. It is fully battery powered. The batteries are set out across the floor of the vehicle and go about 2 thirds of the vehicles length. The body has to be extremely light weight in order for the car to last long on a single charge. The car is almost 100% aluminium and heavier, stronger materials were only used in a couple of places like the front end crash zone. There are no such things as battery powered trucks just yet but there is talk of a battery powered minivan.

I have only been able to think about 1 flaw being present in battery powered cars (besides the premium price that’s been slapped on these vehicles) and that is if there is a power outage, you will not be able to charge your car. Here in South Africa, power outages do occur quite regularly and there’s also load shedding which takes place from time to time.

Without batteries we cannot have battery powered cars. Batteries are going to change the world when it comes to CO2 emissions. You can run anything that needs electricity to run, on batteries, provided you have enough of them.

Just batteries have expertise in all things battery related and can satisfy all your battery needs.

An unorthodox way to test batteries, but does it work?

An unorthodox way to test batteries, but does it work?

Batteries are used in many household items, such TV remotes, electric toothbrushes, your alarm clock and your torches. The only problem with batteries is that they eventually go flat. Before you just pull out the old batteries and throw them away, maybe you should test them to find out whether or not you aren’t wasting batteries that still have some juice left in them.

Testing a battery

There are many ways to test whether your batteries are good or not. You can use a variety of different battery testers. One of the more common tools used is a voltmeter. These test your battery by you placing 2 probes against the poles of the battery, one to the positive and one to the negative. If it reads 1.3 Volts, then it still has some juice in it.

Another rather unorthodox method of testing a battery is by dropping it onto a hard surface.

The method:

A video went viral a while ago showing an experiment where good and bad batteries were dropped onto a hard surface. They dropped the batteries onto the surface from about a foot. If the battery bounces then it is dead but if the battery just drops pretty much dead, then it is still good.

We all have that drawer somewhere in our house where we keep all kinds of things, I don’t know why we keep dead batteries but we do. I’ve often stared at this pile of batteries, guessing which are good and which are bad, I can now do the drop test at home and test them all.

Does it work?

A group engineering students tested this method of testing batteries and they kind of debunked it a little. They were convinced that the method could not test if batteries were dead or not. The results of their tests were that the bouncing of the battery only tells you if the battery is fresh or not. It doesn’t actually test if the battery is flat.

Why does it bounce?

Basically, as you use a battery, zinc oxide is released inside the battery. This is what causes the battery to bounce when you drop it. Because of this Zinc oxide, a battery with 0% charge can bounce as high as a battery with 50% charge.

Benefits of uninterruptible power supply (UPS)

Uninterrupted Power Supply

There aren’t many successful businesses that can operate well without a source of electricity. You can easily picture the worst-case scenario and foresee the real life horror story that will follow. Business is going well along and all seems right wand perfect, until the building or site has no power and a helpless feeling overcomes you.

Reasons for power loss

Utility companies regularly summarise the reasons for any power blackouts in their regular newsletter reports. The cause may range from cable theft to animals making their way into transformers and other components or even when Mother Nature strikes. Whether the power blackout lasts a few seconds or several weeks, business functions need to continue and they need do so continuously, consistently and productively.

The cause of the blackouts may vary, but power outages cause worry about how time-sensitive projects will finish on time and on expected budget. Every business, city and household needs lights, heat, equipment and other necessities to operate without interruption, and certainly to prosper. With constant blackouts and without power, injury, loss, damage and decreased revenue become an un-welcomed reality.

What are UPS Supply Systems?

UPS (Uninterruptible Power Supply), and with a complete UPS system, you can remove blackouts from your list of worries. The machinery continues to improve as the importance of maintaining power to essential operating systems becomes more and more vital.

Many people don’t realize how much the power hungry world has changed overall power needs, as the Internet and technology in general keep driving up demand for cleaner and more reliable power source. Unforeseen energy surges, spikes or dips cause instabilities and irregularities that can unfavourably affect your devices and your data. UPS systems provide a clean, consistent and uninterrupted power flow that protects your business or home against those effects.

Don’t leave your business in the dark with unplanned power outs, we at Just Batteries can assist your business by keeping it running all the time with our UPS systems. So don’t waste time and visit Just Batteries today!

Facts About BEE Accreditation

Facts About BEE Accreditation

BEE accreditation is what’s recently keeping most companies on their toes. How to get accredited, what factors implicate their score, what factors increase their ranking, and what benefits it has on their company on a whole.

Before all those questions are answered, we first need to consider what BEE is.

BEE is an acronym for Black Economic Empowerment. It’s a law that came into practice in companies that allows for people of mixed races to be employed. It also ensures that companies are equally mixed and there’s a fair advantage on all races being employed at prospective companies. Following that, Broad-based Black Economic Empowerment (B-BBEE) is an initiative launched by the South African Government to address the restrictions that exist in the country for Black citizens to participate fairly in the economy.

BEE Ranking works in codes and statuses. Depending on ownership, management, employment equity, skills development, enterprise and supplier development and socio-economic development, companies are scored higher or lower.

For companies to get accredited is not as tedious as it may seem. It’s as simple as an online application, and documentation supporting the oath you take as a company to agree to the terms and conditions of becoming accredited.

BEE accreditation can have many benefits for your company if you stick to your oath, and be rewarding in terms of the change you’re making in society.

On a national level, BEE accreditation can have a positive impact on society as it supports governmental initiatives for transformation. On a business level, it can have positive effects on brand awareness and marketing campaigns. It also provides key financial and relationship advantages with the government. These include being able to take part in tender processes (the higher the BEE ranking, the greater the chances of obtaining a tender) being able to conduct business with government (at all levels, including municipal) and being able to participate as a supplier in the chain of preferential procurement.

It is important to note that BEE is not transformation itself. BEE is part of a reporting exercise and encourages specific activity in businesses. However, it is a quantity measure and does not necessarily consider any quality elements. If transformation is not achieved in the business, then the business will struggle to maintain their BEE score. This becomes more evident the larger the business. So, it is important for all management levels to firstly be aware that the company is BEE accredited, what holding an accreditation means and ways to adhere to the accreditation oath. All management levels should be trained regularly to know how to put accreditation terms and conditions into practice and should thereafter be involved when the company does audits of the desired standard of accreditation.

Companies like Just Batteries are one of many companies that prides itself in holding a BBBEE status.

Who invented the torch

Who invented the torch

Torch History – Who Invented the Torch?

From as early as man can remember, there has been a need for portable light. Flame torches, candles, oil lamps and kerosene lamps were designed for portability but they were highly dangerous because they had a flame as a light source. The invention of incandescent electric light bulb and of dry battery at the end of the 19th century enabled solutions for this problem.

The first dry cell battery was invented in 1896. It was an improved variant of the previous version in that its electrolyte was a paste instead of a liquid. Because of that, it could work in any position and it would not break or spill as easily. It was a perfect power source for a portable light carrying instrument.

In 1899, English inventor David Misell invented the first torch. It had three D batteries placed in a tube that acted as a handle of the device. Batteries powered a small incandescent electric light bulb and a simple contact switch turned light on and off. They were called “flash” lights because they could not throw light for too long and you had to turn them off to rest them from time to time. Early torches ran on zinc-carbon batteries that could not give constant current for longer time frames.

The first torches did not sell too well because of the behaviors of batteries and because carbon-fiber electric bulbs were inefficient. Replacing of carbon fiber with tungsten and improving of batteries made the torch a more useful device. This then increased its popularity and it started to replace lamps with flammable fuel.

By 1922, different torch designs emerged. There was classic cylinder-shaped variant, a lantern-shaped varient that could be left to stand, reflector type for lightning a greater area and a small pocket variant. Different variations and usefulness were reasons of the high demand. This resulted in 10 million torch users by the same time.

Modern torches generally have the same or similar parts and specifications, they also work the similar to the torches in 1922. They most commonly use incandescent light bulbs or LEDS. Torch lights are so common now, that they are made on everyday objects like keyrings or pens, as headlamps on helmets, with clips for mounting on rifles and as high power reflectors. We have them on mobile phones and in hundreds of variants more.

A torch light is an object that basically started as a novelty and turned into a necessity with thousands of possible uses.

Types of Torches

Types of Torches

Torches are often overlooked when building your ideal toolbox, and when you do consider getting one, you only think about getting one standard LED torch. Here are a few types of torches that you probably didn’t know existed, and you didn’t know you needed.

Now that you know all about the different types of torches, you can get a torch that suites you from Just Batteries today!


How Torches Work

How Torches Work

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.

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

How Batteries Work

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.
