How to properly use the Li-ion battery and charge it?
In modern society, you can often hearopposing opinions about the peculiarities of using batteries. This situation is formed due to the fact that the development of innovations in the field of portable electronics and technology is very impulsive and the society does not always have time to respond quickly to improvements.
City's legends
Previously, almost all types of electronicdevices were installed nickel-cadmium or nickel-metal hydride batteries. When using these galvanic cells it was necessary to completely discharge, which allowed them to extend their service life and prevent a drop in energy intensity. Now these batteries have not lost their positions, but the scope of their application has shifted, now they are not found in mobile phones, laptops or tablets. But the winged expression of sellers "first discharge, then charge, repeat three times" is still encountered. After all, such a useful advice in society is remembered, and it is now passed from mouth to mouth. However, the development of progress was on its way, and Ni-Cd, Ni-MH-energy cells began to be replaced by a Li-ion battery, and a little later also with lithium-polymer. Nickel-cadmium or nickel-metal hydride galvanic cells began to occur in less productive electronics - calculators, navigators, amateur cameras and so on. While their more innovative colleagues took their niche in laptops, mobile phones, smartphones, tablets and much more.
Principles of use
The construction by which Li-ionbattery, requires a specific relationship to it. He does not tolerate a deep discharge and can even fail if such a situation repeats. Therefore, all devices that use them, do not sell to those who have sat down - this is how long the life of their energy cells extends. However, the stale thinking of the masses does its black thing - still voices are heard that transfer from mouth to mouth, as it is necessary to charge the Li-ion battery, focusing on the prevailing rules for Ni-Cd, Ni-MH electrochemical cells or even not focusing on their type . After all, even the storage of these energy cells must be carried out in different ways. Nickel-cadmium or metal hydride is important to completely discharge, and lithium-ion and lithium-polymer need, on the contrary, leave an energy reserve of 60-80 percent.
Complaints and Responsibilities
Very often people can be told thatpurchased Li-ion battery does not serve them for a long time and it has to be changed again. For example, after a while the phone is very quickly discharged. Although after the purchase he could work very long and pleased his owner. If you understand, then the fault for this dislocation lies not on the manufacturers, but on the conditions in which Li-ion batteries were charged and used. After all, all the pernicious models of human dealing with them have already been described above, and the master only strictly follows them.
Application features
So, with the work of modern energy cellsIn severe environmental conditions (in the cold or cold), the battery spends far more resources than in a warm room, which causes its increased wear. In such cases, it is most rational to use electronics not too intensively (not to run GPRS-Internet, navigation, games and other resource-intensive applications), then the service life will be much longer. There is also a natural question: how to charge Li-ion battery under such conditions? The device must be connected to power sources in a warm room, when it is not fully seated. Thus, the battery is operated under the most favorable conditions for which it was designed.
"Preservation" of galvanic cells
If you need to keep the Li-ion 18650 battery in working condition, which is used for different devices irregularly or once, then the following measures should be taken:
- charge it to 40-50 percent;
- Remove from the device;
- hermetically pack in polyethylene, if possible, create a vacuum in this package;
- each battery is stacked separately from the others;
- move the galvanic cells in the refrigerator (but not in the freezer);
- Once a few months, remove from there and after warming up at room temperature, restore to the above capacity;
- fully charged before use.
These measures will help to keep your battery, and itwill not lose its effectiveness. Since they are designed for permanent use only in conditions where you would feel comfortable - at room temperature or close to it.
Use of quality equipment
In addition, any type of battery - Li-ion, Ni-Cd,Ni-MH - should be charged by the original device, which is recommended by its manufacturer, since cheaper analogues are very different from the original equipment in their parameters. After all, even a slight excess of the nominal voltage can shorten the battery life in almost two times. In the opposite case, ie, a drop of only 0.1 volts, the battery life is reduced by more than 10 percent, and the battery is never fully charged. With regular use in this mode, it loses its capacity and no longer corresponds to the declared values of the manufacturer.
