The AA battery was first introduced over a hundred years ago. It was only the latest iteration of technologies of dry batteries , which were improved during the nineteenth century. But this thin cylinder can be one of the most popular battery sizes ever created. In the mid-twentieth century, the AA size, which we use today, was completely standardized. Since it was only a matter of improving the internal mechanisms compact and distributed sources of energy, and today the modern consumer has the three main categories of AA battery, of which you can choose.
The first is well known to all: a single use disposable AA alkali użytkuBateria. Reliable, decades the batteries are inexpensive and effective, easy to provide power to the device from the lanterns after cameras, music players and not only. AA alkaline batteries produce 1.5-volt output, which in most cases remains stable to the depletion of the energy stored in the battery. Despite the many obvious advantages, including the aforementioned low price and reliable long-term storage of such batteries have disadvantages. A alkaline battery is only suitable for devices with low power consumption such as a timer or a remote control. Alkaline batteries are also known from the leaks “acid battery”, which is ironic, because in reality the fluid which can flow, a water solution of potassium hydroxide, standard solution. These leaks are especially dangerous,
More common nowadays are lithium battery AA. Although these batteries are much more expensive than alkaline AA batteries, they offer much more power than their alkaline equivalents, even if some electronic components operate almost ten times longer than alkaline units. Batteries lithium AA, they are also easier and have impressive longevity in storage is not measured in years but dziesięcioleciami. Their price makes them, however, nielogicznym choice for many purposes.
Finally, we have a category of rechargeable AA batteries. These devices mean initial investment, which may seem much too high, especially that require the purchase of a unit charge. However, their capacity for multiple use, and soon you will discover that AA compressor pay themselves for their savings.
For people who rarely use the battery, but should have them in good condition when needed, an expensive lithium battery may be considered as an investment in reliability. For those who need battery, for frequent but less demanding applications with low consumption, alkaline batteries makes sense. And for the person who seems that she all the time goes by batteries, cash money on batteries, it’s a smart move that will pay off over time.
The basics: How it works battery
Scientists have long known why and how a battery generates usable electricity ; despite the fact that most of us use batteries every day, the majority of the members of the society cannot wait for the explanation of their functions.
Contrary to popular belief, AA battery not keeping current . In fact, these batteries actually produce electrical energy by converting stored chemical energy into electrical current.
AA battery has only three main components. These include two terminals, commonly known as positive and negative, but called respectively the anode and cathode . The third component is placed between the two lugs and is an electrolyte , also called the center of the chemical industry.
When the battery is filled with the potential energy of a chemical is inserted into a system that creates a circuit when both terminals are connected are so chosen that the chemical reaction creates an accumulation of electrons at the anode. Then they pulled out the battery, and pass through the device, and transmits a light bulb, speakers, a screen or other electronics function.
Safe storage and disposal of batteries
To ensure maximum life from the batteries, keep them in the bottom of the scale at room temperature (around sixty degrees Fahrenheit is ideal) and in a relatively dry environment, not exposed to direct sunlight. There is no reason to store batteries in the refrigerator and should not be stored in the refrigerator; it Can lead to serious damage to batteries, as the condensate causes corrosion problems. Regardless of where and how you store batteries, you should do it in its original, factory sealed packing as long as possible.
Batteries should be kept at about half their power; it prevents their complete exhaustion that can sometimes prevent re-download. Alkaline batteries must be completely worn out and then thrown out; rarely have a reason to maintain the alkaline battery, which was partially used.
Most alkaline batteries can be safely disposed of with other regular trash . Modern alkaline found for sale on the Western markets, do not contain any harmful chemicals such as mercury, which are deprived of such products hazard. Just remember not to get rid of large amounts of alkaline batteries since a lot of devices that come into contact with each other may present a risk of heat or fire due to traces of residual energy.
Lithium batteries (and other special batteries, for example, comprising zinc) may require special disposal at the point of processing. Check the rules of your region, and if this special step is required, weigh it, recycling of these batteries together with the rest of the basket may allow leakage of harmful chemicals to the land, water sources or air.
Remember that just because many types of batteries can be thrown in the trash, still, they can be recycled , and make this a great way to minimize the negative impact of Your business on our planet.
