Thelife of the laptop’s battery depends upon multiple factors. One of the most
important factor is the system
you follow to charge the
battery and how it gets
discharged. Its like memory in
the battery. The battery retains your habits of charging/
discharging and after some
time, it is never fully charged
or discharged.
For instance, you will notice
that when you purchased the laptop the battery lasted for
around 2 hours, but now it
lasts only for around 45
minutes. This is because, you
probably keep the laptop
connected to power cable for long intervals of time and the battery has forgotten its ability.
To restore its capability a
complete charge and discharge
cycle is required. This is called battery calibration. You shouldcalibrate your laptop’s battery at least once in a month to prolong its
life and mileage.
How to Calibrate
Laptop’s Battery
1. First charge the laptop’s battery to 100%.
2. Assuming that you are on windows, Go to Control Panel >
Power Options. Now change the
hibernation settings such that
the laptop auto hibernates
when the battery level reaches
4%.
3. Now use the laptop normally until it auto hibernates.
4. Now leave the laptop alone for at least 5-6 hours.
5. After this, charge the battery again to 100%. That’s it. Calibrate your
laptop’s battery once every
month to increase its life span. Important Note - This method
of calibration works only if your
laptop uses Ni-MH cells in the
battery. If your laptop uses Li-
Ion battery, then DON’T USE
this method as it will decrease the life span of your Li-Ion
battery. Check your laptop’s
manual to find out the battery
type.
