You just bought a laptop but do not know how to do the first charge of the battery?
Then you’re in the right place because in this article I will explain how to correctly perform the first charge of the battery of your new computer (or your new battery) and also how to make subsequent cycles of charge and discharge.
How to make the first charge of the battery of a laptop?
The modern laptops, which are notebooks, netbooks, laptops, or ultrabook, mountains of lithium-ion battery that, in general, can take up to 2 to 3 hours to fully recharge (with the computer off). When you buy a new battery or a new laptop, the battery is already loaded instead partially around 40% then, for the first charge of the battery, you just have to mount it on your laptop and charge it fully without booting the Windows operating system, Linux or Mac OS of your computer. It should be noted that you fully charge the battery, it does not mean that you have to charge it for 12 hours, but simply that you have to load as you do normally even subsequent times (ie more or less a couple of hours), that is, until the LED that indicates the battery will not turn off (or will have changed color).
How to make subsequent cycles of charge and discharge?
Once you have made the first charge cycle, if desired, you can also disconnect the power supply to start using the laptop for the first boot. In subsequent cycles of charge and discharge, you may have to discharge the battery for up to 5% (or at least until he tells you the operating system), and also can do even less to fully charge up to 100% (you can stop for example, already 80%).
One very important thing to say is that there is no need to fully discharge the battery before charging, this is because the modern lithium ion batteries do not suffer from the memory effect (who had the old batteries based on nickel). Also remember that you should do a battery calibration at least once every 30 cycles of charge and discharge, that a partial charge is better than a total (and not cause any harm as opposed to a complete discharge) and that it would be better to charge the battery when the laptop is turned off (even through the night, so, once charged the battery, the power supply stops loading).
Now that you know how to make the first charge of the battery of a notebook PC, whether you use your computer always with the power supply attached, you should also read this article to know how to behave in this situation.
