During the process of notebook, we do not intentionally charge the notebook battery to 100% State-or fully discharged battery notebook protect automatic shutdown. The right way is that the battery in 20% at 98% state and stop charging. If the machine power calibration, when the battery has reduced standard-by-time considerably. Then you calibrate the battery in time, the active protection circuit performance.
For early Dell Latitude d620 battery
(Ni-MH Ni-MH or Ni-Cd Ni-Cd), really full, GE must unload and to obtain good battery capacity. But for the lithium battery is not necessary, it can also damage the battery.
In fact, the lithium battery has a small memory effect. The lithium- Dell Studio 1537 battery
Materials is very sensitive to the conditions such as temperature, the use of frequencies and so on. The battery is (reduced standby time) after some aging time used. The natural wear and tear is an important reason, and inadequate maintenance is another important reason.
A well-designed lithium battery has a very good protection circuit to prevent excessive costs and discharge.As over-charging and discharging the Dell Vostro 1510 battery
is the rapid reduction of its activity. Under the protection of the protection circuit, the user complete charge and discharge the battery several times in fact impossible, “full” level was reached.
Sometimes Windows shows that Dell Studio 1535 battery
Capacity is 20% or more, for 30 minutes. But after 10 minutes or less, the machine will automatically shut down suddenly. The reason for this is that the battery is aging of the battery protection circuit monitors the battery can not be true capacity. In the normal battery, have the protection circuit original parameter was not correctly reflect the current situation of the battery
So power calibration is the benchmark protection circuit parameters correctly, accurately reflecting the actual capacity of the Dell Inspiron 5150 battery
. This correction process is often two or three complete charge and discharge. As already mentioned, complete charge and discharge the battery-less activity. It is not used often, usually once a month.
