From what I have observed for the past months of encounter with notebook users, I have noticed that their notebook is "ALWAYS" powered using the wall AC socket. This is a common practice by individuals whom believed that with doing so their machine will be constantly available and powered.
Here is the catch! A few
reported that their internal notebook battery is totally flat out and cannot be
recharge. Hence the user completely relies on the availability of a power socket
and has to spend few hundred "RM" for a battery unit.
Why is so? I have
discovered the same goes to my hand phone Lithium Ion battery. So I smell
something fishy. What I have found was that if a battery is always fully charged
and is not discharged over a period of time will have its lifespan shorten.
Imagine the battery unit
as a small box of
apples; consumers constantly refill the box if 10 to 20 percent of apples were
eaten or taken. By this way the apples located at bottom part of the box remain
fresh for the few days and turned rotten and no longer edible thereafter.
