Laptop battery memory effect.
In lithium-based laptop batteries this is in fact a myth, it only applies to older Niquel-based batteries. So fully discharging and charging the battery is completely useless and even harmful as we will see below.
The modern lithium notebook battery can be charged regardless of its current percentage, given that it has absolutely no negative effect in its performance.
| Should I remove the laptop battery when Dell Inspiron 1720 AC Adapter is plugged in?Many laptop users have this question and we will answer it right now: The answer is: YES and NO, it depends on the situation.Having a battery fully charged and the laptop plugged in is not harmful, because as soon as the charge level reaches 100% the battery stops receiving charging energy and this energy is bypassed directly to the power supply system of the laptop. However there’s a disadvantage in keeping the battery in its socket when the laptop is plugged in, but only if it’s currently suffering from excessive heating caused by the laptop hardware.
So: – In a normal laptop battery usage, if the laptop doesn’t get too hot (CPU and Hard Disk around 40ºC to 50ºC) the battery should remain in the laptop socket; – In an intensive usage which leads to a large amount of heat produced (i.e. Games, temperatures above 60ºC) the battery should be removed from the socket in order to prevent unwanted heating. The heat, among the fact that it has 100% of charge, is the great enemy of the lithium battery and not the plug, as many might think so. Dell Vostro 1720 Battery discharges
Full battery discharges (until laptop power shutdown, 0%) should be avoided, because this stresses the battery a lot and can even damage it. It’s recommended to perform partial discharges to capacity levels of 20~30% and frequent charges, instead of performing a full discharging followed by a full charging. Laptop batteries contain a capacity gauge that allows us to know the exact amount of energy stored. However, due to the charging/discharging cycles, this sensor tends to be inaccurate overtime.t Some laptops include in their BIOS, tools to recalibrate this battery gauge, which is nothing more than a full discharge followed by a full charge. An inaccurate gauge can lead to the fact that the the battery capacity values are are wrong. The Dell Vostro 1320 Laptop Battery may report that it still has 10% of capacity when in fact it has a much lower value, and this causes the computer to shutdown unexpectedly. Discharge (or charge) cycles consist of using all that battery charge (100%) but not necessarily all at once. |
