How to choose the battery for the laptop?
The battery is a very good accumulator that turns the laptop into a fully mobile device. This is one of the reasons why the choice of the battery for a laptop is a task not to be taken lightly. Discover through this content, how to choose the battery for the laptop.
The reference of the battery and where to look for it
The reference of the battery is usually located on the accumulator. What you have to do is to take the battery out of the computer to check the identification sticker. Apart from that, there is other information, such as the country of production or the danger indications . There is also an individual code. Depending on the computer manufacturer, this individual code consists of different letters and numbers, as is the case with the for example.
The whole thing is not just about finding the battery with the same reference as the original one. Another important parameter to pay attention to is the voltage of the battery. The computer is equipped with 10.8 V batteries, precisely about its energy needs, or 11.1 V and 14.4 V (or 14.8 V) batteries, which are all equally compatible. The voltage is closely related to the number of cells: a 10.8 V battery usually has 6 cells and a 14.4 V battery has 8 cells.
The final parameter to consider is the battery capacity. It is usually expressed in mAh (milliampere-hour) or Wh (watt-hour).
The mAh represents a unit of cell capacity itself. It is nothing more than the amount of electricity supplied in one hour by a current of 1 ampere. The Wh informs about the autonomy of the battery. For example, if the energy need is equal to 20 watts, then the 48 Wh battery is able to feed the computer for 2,5 h of time.
