To understand the technology, the current in the charger must first be acquainted with the work of batteries. Basically, the battery consists of two different metals separated by a little porous insulating material. Metals must have the capabilities and chemical properties that are not equal. The chemical potential is the energy, which by nature is stored in the particles and atoms that are in the metal itself.
Due to the lack of equilibrium of the chemical potentials in the two metals, when connected to the circuit, the battery works automatically in order to balance himself. In this process, the flow of electrons flows from the metal used as the anode, which has a negative charge, through the perimeter and back to the metal used as the cathode, which is positively charged. Due to the fact that the anode may refuse to load the negative cathode to absorb emitted by the electrons when they pass through the circuit. Somewhere along the way you can electrons to top up the mobile phone, car or something else.
In standard batteries, often referred to as primitive, the flow of electrons cannot be replenished. When worn or the anode or the cathode, the battery is not able to bring anything. The most popular type of primary battery utilizes zinc as its anode and coal as the cathode.
Batteries work because their stream of electrons can be reversed. It is only in the case of certain pairs of metals, including Nickel and cadmium, which are common in household batteries AA and AAA.
Charger batteries are due to changes of flow of electrons . In this process, the metal which works as the anode during the technical release, becomes the cathode and Vice versa. Because of this, these definitions are usually used in the case of batteries. The charger uses a constant current, to ensure this process, usually extracted from the outlet or USB port, which houses the batteries, home.
This process also applies to other types of batteries such as those used in cars . So the battery would successfully charge used current should be slightly larger than its output. Strong currents can quickly charge batteries, but also increase the risk of overheating damage or explosion.
Why use batteries
Advantages of using batteries are countless. On the one hand, although the costs of batteries can be a little more than their disposable counterparts, in the long run will save money . Of course, the total cost can exceed long-term benefits for some customers. Given this, within a few years the savings becomes significant . The more batteries you use, the faster return of investment.
Investing in a matching set of batteries and one charger from our list of benefits will continue. Perhaps the most noticeable result will be that it will be a long time before you have to go and buy new batteries again, if you ever will. If disposable batteries, AA or AAA, often in the shopping list will definitely notice the convenience when no longer needed. Instead of having to remember about buying new, just remember to recharge them. It shouldn’t be too hard, as is likely, used to throw batteries from the unit when they’re dead, and throw them in the trash. If you’re worried you’ll forget, just let go of my phone charger next to the waste basket.
In addition to personal savings and time, which you will experience with a rechargeable lithium-ion battery, you’ll also help our planet . In addition to take the place of in landfills, used batteries also result in harmful substances such as mercury and bring to the ground. Disposal of batteries can alleviate this problem, but this option is not available everywhere. Even where many households can’t afford more problems with the supply batteries to the designated place of unloading. While some States to dictate to the residents to do it, the extortion of this policy difficult.
Most batteries can be recharged up to 1000 times. This means that in the long run you will save yourself the cost of 999 disposable batteries. If you normally throw away used batteries in the trash, these extra batteries 999 remains outside used as a warehouse. Okay, you can Pat yourself on the back.
If you have ever previously bought batteries, home may have noticed that there are several types. In truth, there is much more types of batteries than those that can be found on the shelves in supermarkets and electronics stores. Lead-acid batteries provide the most vehicles, while the lithium-polymer technology found in many mobile phones.
The most common battery types AA and AAA batteries, Nickel-cadmium, Nickel hydroxide and lithium-ion . Batteries alkali manganese are also available and often they are cheaper than other options, but usually have a limited life cycle. For comparison, lithium-ion batteries are typically the longest of all types.
The self-discharge is a phenomenon consisting in the fact that the battery loses charge when not in use, and is present among all types of batteries, including disposable. While rates are higher in the case of batteries, there are many factors associated with the rate at which the battery loses charge. These include: age, storage temperature, and charging capacity, which is stored in the battery. If it is usually time storage of disposable batteries, it can be represented as a percentage in the case of batteries.
Li-ion batteries usually have the lowest discharge rate of all battery types. As a rule, the bulk from two to three percent of their cargo every month during storage, compared to four to six per cent in the case of lead acid, and from 15 to 20% in the case of Nickel and cadmium. Standard battery the Nickel metal or the Nickel-metal Hydride batteries have a high self-discharge rate even up to 30 percent per month. To overcome this effect, Sanyo introduced in 2005. Called the so-called Eneloop style NiMH low self-discharge . They have a self-discharge ratio is closer to the models of Li-ion battery.
