charge the laptop until it is full, then unplug and use it
until it is
almost dead, then plug it in again ...
keep the charger plugged in all the time
use the laptop with the battery removed and keep the battery
fully charged
use the laptop with the battery removed; don't keep the battery
fully
charged
Batteries
degrade through the charge/discharge process. When at home
I
keep my 8500 on AC power with the battery in place. Battery
is always
fully charged for whenever I need to go mobile.
Most modern laptops use Lithium Ion batteries. They have
a typical life of
300 full cycles so if you charge and discharge every day you
will wear it
out in a year.
The chargers in modern laptops will shut off when the battery
is fully
charged so there is no need to worry about overcharging.
NEVER deep discharge a lithium ion battery - doing so even
once can
permanently damage it.
Li-ion batteries work best when topped up regularly. Whether
you use it
or not, it will eventually deteriorate from age - 300-500
charge cycles,
or about 18 month-2 years before many no longer hold sufficient
charge.
I think I am very lucky on this matter. I use the laptop
all the day
and charge it two times each day (no power outlets where I
am usually
working but a nice wlan instead!). Once charged, I can use
the laptop
three hours (sometimes a bit more). About two years ago, a
full charge
allows me to run the laptop up to four hours. I think that
this battery
has more than 1000 charge cycles...
Certainly I am very happy with my used
Latitude CPi laptop!
Of course I do full charge/discharge cycles! |
