Advantages of Solar Street Lights
Present-day technological innovations have revolutionised the way to the rebirth of street lights through solar powered ones. Solar street lights are raised outdoor light sources, which are powered by solar panels. These panels are mounted on the street light pole/pillar structure or connected in the pole. Solar panels have a built-in rechargeable power source, supplying power to the fluorescent or LED light during the whole night. Majority of the solar panels automatically sense sunlight through a light source sensor. These can give off light on a number of nights even when the sun’s energy is not available for a few days. Many provinces are switching to solar street lights these days due to load shedding.
Solar street lights are self-sufficient and work independent of the utility grid resulting to fewer operation costs. This means that you are not connected to the electricity provider. The street lights are dependent of the sun energy given off by the sunrays, storing as much of it throughout the day for night use. Eco-friendly street lights need far lower maintenance and repairs than coal powered street lights. These have lower chances of malfunctioning. Since solar panel wires do not have external cables, the risk of accidents is much lesser. Majority of the time, accidents happen to the repairman who fix the street light. These can include serious burns or electrocution. Solar panel street lights are eco-friendly mainly because its panels are solely dependent on the sun hence removing your carbon footprints contribution to the area they are in. Some parts of solar panel street lighting systems can be easily erected in remote areas making these more efficient and handy solutions to lighting problems in rural areas.

Benefits of Asset Tracking for Livestock
Benefits of Asset Tracking for Livestock
One of the first applications of RFID (Radio Frequency Identification) has been in livestock tracking. Mainly because, livestock assets are regularly on the move, historical methods of identification and data collection in livestock have proven quite unproductive, generally in the case of large herds of livestock. RFID overcomes the drawbacks of manual tracking by being fast and efficient without requiring a visual or line of sight for data recording. Furthermore, radio frequency signals safely penetrate animal tissue; RFID tags can be safely clipped on or even implanted inside animals and will last for the entire life span of the livestock.
Therefore (Radio Frequency Identification) allows the documentation and tracking of individual animals over their life span, even in a herd of hundreds of thousands. This being so, each RFID tag is unique, a livestock data base that keeps track of the animal’s source and growth, parentage and breed can be easily obtained. Continuous tracking over generations of livestock creates a genetic data base that helps construct a lineage and continue quality of livestock and improve breeds. Each data base can be integrated into a provincial or national livestock identification system that records nationwide livestock location, ownership and trade, creating a ready reference for farm owners, breeders and health officials.
For instance, where there is global trade in livestock and food products, correct tagging and record keeping is of extreme importance, particularly since livestock diseases can quickly spread over large areas, wipe out whole herds and possibly spread globally. Radio Frequency Identification usage helps monitor health of the livestock, keep individual medication and vaccination history, and block the spread of disease by tracking and divide infected livestock at early stages, leading to successful isolation and treatment that saves the rest of the livestock.

Safely Storing Batteries when They’re Not Being Used
With so many devices in our homes and places of work that require battery power, it is always a wise strategy to stock up spares and to keep them handy when your current ones die. Even rechargeable batteries have a limited lifespan, so it is good to stock up on them as well. But when storing batteries for later use, it is essential that you take the right precautions in order to keep them protected, ensure that they get their full lifespan, and of course to make sure that they can be used safely in the future. So, to help you get the most out of your energy stockpile, here are some tips on how to store your batteries correctly, and how to dispose of them when they are done.
Keep Them Mint if You Can
A good start when storing batteries is to keep them in their original packaging wherever possible. This will keep them protected in accordance with manufacturer standards; essentially keeping heat and conductive materials out. They will also help you remember which of your batteries are new, and which ones will underperform.
Sorting for Storage
You may find that your battery storage is made up of units of varying age and condition, in which case it will make things easier on you to categorise them accordingly. This will allow you to go through the lesser quality ones before starting to deplete the new ones, which will help you get the most out of each unit’s lifespan.
Keep them Away from Heat and Humidity
Remember to store your batteries in a cool, dry place (as is often stated on the packaging). Keep them stored under room temperature of lower, and be sure that there is as little humidity in the area as possible. Furthermore, any conductive materials might lead to corrosion over time, so be sure to keep the storage area clear of them.
Disposing of Used Batteries
Once your batteries are done, it is your responsibility to the environment and to personal safety to make sure that they are disposed of properly. Batteries are made up of harmful materials, which makes this point all the more important.

With alkaline batteries, it is generally okay to throw them away with your general household waste since they no longer contain mercury in them, and are therefore not toxic to dispose of in dumps. Many AA and AAA batteries on the other hand, such as lithium and nickel cadmium ones, contain high levels of toxic materials, and should therefor either be properly recycled or returned to the retailer to be properly disposed of.

How to Test for a Bad Battery
Batteries of all types have a limited lifespan, even rechargeable ones. This can make things difficult since we all have appliances in our homes that are reliant on them. It is virtually impossible to judge a battery’s condition at face value (except where damage has become so severe that there are obvious leaks), and not everybody has the equipment on had that is necessary to get an accurate reading of your battery’s position in its lifecycle. Fortunately, there are a few ways to determine the charge and health of your batteries (however crude some of them might be). Keep reading to find out what they are, and how to do them.
Use a Multi-Meter
Mustimeters are used in a few electrical applications as a tool for measuring current, resistance and voltage. They have a range of uses, but are also well suited to testing the condition of batteries through a direct charge. While it is an effective and accurate means of measuring the exact condition of batteries and cells, not everybody is likely to have one on hand whenever they need it.
Physics is Your Friend
AA and AAA batteries can be tested quite easily with this simple method, although it doesn’t give you quite the accuracy of a multi-meter. Alkaline batteries fill up with a gas when their cells deplete, which changes the way they behave when dropped. A charge battery will likely not bounce when dropped a close distance from a flat surface, while depleted ones will make a blunt sound on impact and will bounce a few times. Do this by dropping the negative side (the flat part of the battery) face down and carefully listen to, and watch for its movements.
Compare Charges with Specifications
If you want to tell whether or not your batteries are truly on their way out, simply give them a full charge. Now take note of a few things:
- How long did the battery take to complete its charge?
- How long does it take the battery to be depleted from a full charge?
Now take the answers from these questions and compare them with the stats given by the manufacturer. If the margins are too wide, your battery is readying for a swan-song.

Once your batteries start working their way out, you will want to make a plan to have them replaced with high-quality products. To view our selection of products, contact a representative from Just Batteries today, or visit our website for further details.
Battery powered cars
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.
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)
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
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
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
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.
- Incandescent bulbs: These torches have been around the longest and are often the cheapest. The lamp produced is usually bright, but this type of light wastes energy by producing heat. Batteries and bulbs don’t last a very long time with this type of torch
- LED lights: Light-emitting diodes are a type of semiconductor. LED torches have a long life because they use little energy. LED torches have no glass or fiber, making them durable. Both the batteries and the bulbs in LED lamps have a much longer life than incandescent bulb torches, but this may make them more expensive.
- HID: High Intensity Discharge bulbs have an electric current which passes through an arranged ball of ionized gas. HID torches aren’t as common as other torches, they are bulky and often expensive. They do however produce a very bright light with a long-lasting bulb.
- Xenon, Halogen and Krypton bulbs: Some incandescent bulbs are filled with a pressurized gas, which helps extend the life of the fiber inside, so the bulb burns brighter without running the batteries faster. Currently, these are the brightest torches available, although they are not as rugged or long-lasting as LED torches.
- Shake torches: You may have heard about Faraday torches, which are named after Michael Faraday, the man who discovered the electromagnetic principle. By shaking the magnets inside the torch for about a minute, you’ll get several hours of LED light. The light isn’t very bright, but having no batteries to use this torch means that it will always be ready for usage, making them perfect for an emergency. When using these torches, be careful! The magnets used are quite powerful and can damage computers, credit card strips and pacemakers.
- Headlamps: Being hands-free, headlamps are a popular addition to torches, especially for hikers and cyclists. Like most torches, headlamps are available with different types of bulbs. Many headlamps are adjustable to various levels of brightness and to different angles, making them perfect for all sorts of activities that require free hands.
- Lanterns: For an ambient glow while camping or during a power outage, a lantern can be a great alternative to a regular hand torch.
Now that you know all about the different types of torches, you can get a torch that suites you from Just Batteries today!
