History behind the battery
Timeline of The History Behind the Battery
Below we have some interesting points on the history of the battery.
- In 1748 Benjamin Franklin was the first person to coin the “battery” term. He used it to describe charged glass plates.
- In 1780 – 1786 Luigi Galvani had demonstrated the electrical basis of nerve impulses where he also provided the cornerstone of research for other inventors to then create batteries.
- In 1800, the Voltaic Pile was invented by Alessandro Volta, he also discovered the very first practical method of generating electricity.
- In 1836, the Voltaic Pile was not able to deliver electrical current for a very long time. The Daniell Cell was then invented by the Englishman, John F.Daniell, it used two electrolytes namely the zinc sulfate and the copper sulfate.
- In 1839, the very first fuel cell was developed by William Robert Grove, by combining hydrogen and oxygen it produced electricity.
- In 1839 – 1842 Improvements were created to batteries, they used liquid electrodes that produced electricity.
- In 1859, the first practical storage lead-acid battery was developed by the French inventor Gaston Plante, this battery could be recharged.
- In 1866, the carbon-zinc wet cell battery (Leclanche cell) was patented by the French engineer Georges Leclanche.
- In 1881, the first battery with both the negative electrode and porous pot placed in a zinc cup was patented by J.A. Thiebaut.
- In 1881, the first commercially successful dry cell battery was invented by Carl Gassner.
- In 1899, the first nickel-cadmium rechargeable battery was invented by Waldmar Jungner.
- In 1901, the alkaline storage battery was invented by Thomas Alva Edison. It had nickelic as the cathode material and iron as the anode material.
- In 1949, the small alkaline battery was developed by Lew Urry.
- In 1954, the first solar battery was invented by Calvin Fuller, Gerald Pearson and Daryl Chapin. A solar battery converts the sun’s energy and converts it to electricity.
- In 1964 Duracell was incorporated.

How an electric car battery works
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
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.
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 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
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.

Using Batteries Safely
Batteries of all shapes and sizes form an integral part of our daily life, whether they power our phones to enable communication, keep the clock on the wall running, or are being used in appliances in and outside of the home, there is no denying that we all use them at some point or another. Though as useful and necessary as they are for our daily lives, they do come with their own sets of dangers. Which is why, as an end-user of a battery product, it is your responsibility to familiarize yourself with how to use them safely. Doing so will not only keep your family and appliances protected, but will also let you do your part for lessening humanity’s impact on the planet.
So, to help you be a responsible battery user, here are a few simple tips on how to use them safely:
When storing batteries, it is a good idea to keep them in their original protective packaging until they are needed. This will help you keep them separated according to make and age, allowing you to easily identify which ones are okay for you to use. When storing rechargeable batteries, be sure to check their charge regularly to ensure they are still functional.
Avoid storing them in hot locations such as in the car or anywhere with excessive sunlight; they should remain at, or below room temperature to ensure that they can be used safely later on. Be sure too to keep them out of humid or damp environments to eliminate the chance of galvanic corrosion or rust, while ensuring that they are not being interfered with by any electrical conduction.
Using them appropriately
Be sure to source batteries only from trusted brands and battery manufacturers and suppliers to ensure that you are using a quality product that can be used safely, while only using the appropriate type of battery to power appliances. When a battery is depleted, to avoid leakage or damage, it should be replaced immediately, and disposed of properly. Batteries that are not specifically labelled as rechargeable should never be charged, and under no circumstances (even after depletion) should they be given to young children, or left in places where they can be easily accessed by them.
Disposing of batteries properly
Never crush or burn a discarded battery, since this could result in ruptures or leakages of battery acid which may be corrosive and pose a danger of toxicity or contamination. Batteries thrown into fires may even pose a risk of explosion. While normal batteries are fine to dispose of with general household waste, rechargeable ones should rather be recycled.
