Batteries for any notebooks And what is the battery? It's no secret that the duration of the laptop is completely dependent on the capacity of its battery. Considering the battery life of more detailed and thorough, it is worth immediately determine the very notion of "laptop battery". Thus, under the battery for a laptop (battery synonym) refers to a special device for storing and using the stored energy. Work Battery is a movement between two metal pieces that are placed in a special acid solution. Every battery has the following characteristics: – capacity – current samozaryada – stress – the internal resistance – durability. Let's look at the most important and significant parameters, which you should look for when buying batteries for your laptop. Battery capacity under battery capacity, I understand the maximum amount of energy stored in a fully charged battery. Currently, even the inexperienced user knows that the more battery capacity, the longer will work for your laptop or mobile device.
The unit of capacitance is the milliamp-hours, which are conventionally denoted by mA / h. Battery capacity is usually indicated directly on the body of the battery. Many buyers now interested in the question: "How real is the indicator of battery capacity indicated on the package, and the true capacity of the battery?". In fact, the gap between the real and the declared capacity can range up to 80%. Such gap is due not only malice of some producers, but also operating conditions and shelf life of the laptop battery itself.
Speaking of the battery capacity and the direct dependence of this index on time, it should be noted that the laptop battery needs to "break up" as well as mobile phone battery. That is absolutely a new laptop should be fully discharged and recharged for 3-5 times. Classification Battery Virtually every mobile user then heard that the batteries are lithium-ion (Li-Ion) and Lithium Polymer (Li-Pol). These batteries are used in laptops. In addition, there are Lead Acid (SLA / Pb), nickel-cadmium (Ni-Cd) and nickel-metal hydride (Ni-MH) batteries.
