What have you
done to extend laptop battery life? Some people do not know how to do it by
their own think about doing some bad things on the battery.
Many people have
a wrong idea about laptop battery repair by adding it to your NiMH or NiCD
laptop battery by placing it in a sealed plastic bag and freezing it for 12
hours. If you use lithium-ion or lithium-polymer batteries, freezing them is
very dangerous. Instead, consider doing a battery calibration, which will
restore and extend your battery charge. Although these methods do not make your
batteries as good as new ones (you may only get about thirty minutes of extra
charge from the old batteries without the need to charge), they will help you
get the most out of your batteries until you can Charge to buy a new one .Reviving a
NiMH or NiCD Battery in the Freezer
1
Determine if you have
the right type of battery for this method. First, this method won’t work for Macs, as
they all have lithium batteries.[1] Your battery has to be
NiMH or NiCD in order for this method to work. If you do this method with the
wrong battery, the battery will likely be destroyed.
Turn
the computer off, then open the battery cover (typically on the bottom of the
laptop). If the battery says something like Li-ion, Li-on, Li-ion II, Lithium,
LiPo, you do not have the proper battery for this method.
If you
are unable to read the text on the battery (perhaps it rubbed off), call your
computer manufacturer to find out, or use a different method.
If
your NiMH or NiCD battery no longer holds a charge at all, this method may only
get you an additional 30 minutes or so of battery charge capability, which is
much better than 0 minutes. If the battery is simply draining too quickly, you
may be able to get better results with this method.[2]
2
Remove your NiMH or
NiCD battery.[3] With the computer
turned off, gently remove the battery from the laptop. The battery should come
out without having to use much force.
3
Place the battery in a
sealed plastic bag. Any high-quality sealable bag will work. It’s important to make
sure the bag is completely sealed and contains no holes.
4
Put the bagged battery
in the freezer for about 12 hours. Don’t leave the battery in
there much longer than that, as freezing it for too long could cause it to
explode.
5
Remove the bag from
the freezer. Take the battery out of the bag and let it warm up to room temperature,
drying it occasionally with a towel if it appears damp. Let the battery warm
back up to room temperature for up to 30 minutes before continuing.
6
Put the battery back
into the laptop. If there is a cover that goes over your laptop battery, slide it securely
into place as well.
7
Connect the laptop to
a power source. Without turning the computer back on, plug the machine back in to a power
source and leave it this way overnight (or for several hours during the day).
8
Drain the battery. To drain the battery
quickly, it’s best to
turn the computer on, unplug it from the power source, and do something
system-intensive, such as watching a video with the screen brightness turned
up.
9
Charge and drain your
battery again. Do this step at least twice, but preferably 4-5 times. Once you’ve followed these
steps, your formerly-dead battery should now hold a charge for a least a half
hour, hopefully more.
Re-calibrating Any Laptop Battery
1
Determine if this
method is right for you. This method will work for any type of laptop battery. Re-calibrating the
battery fixes issues where the battery meter on your laptop no longer appears
accurate. It also does a complete discharge and recharge, which can add extra
life to your battery.
2
Charge the battery to
a 100% charge.[4] It doesn’t matter whether the
computer is off or on for this step, but you’ll need to have the
computer turned on eventually to know whether or not the battery has reached a
full charge. Once the battery meter reaches 100% leave the computer plugged in
to the power source for two more hours
3
Drain the battery. Disconnect the laptop
from the power source and drain the battery completely. You can speed up this
process by using the computer to do something system-intensive, such as
watching a movie or editing video.
4
Leave the computer
unplugged for 3 to 5 hours after the drain. This will ensure that
any phantom power is fully drained from the unit.
.
5
Fully charge the
battery. Charge the battery back up to the 100% mark. At this point, your battery
has been recalibrated
Performing a Full Recharge
1
Decide whether this
method is right for you.[5] Doing a full recharge
will work on any laptop hardware, no matter the battery type. Try this method
if your battery is draining more quickly than it used to.
2
Completely drain the
battery. Even if the computer is turned off, the battery may still have enough
charge to power the LED power light. You'll know the battery is completely
drained when the power light no longer blinks.
3
Charge the battery
with the computer turned off. Plug the computer back in to begin the charging process, but don’t turn the computer
on. If the computer turns on without your prompting, shut it down right away.
4
Leave the computer
charging (and turned off) for 48 hours. Don’t turn the computer on
for the entire 48 hour charging period.
5
Turn the computer back
on after 48 hours. The battery should now be able to hold a charge better than before.
.
Different methods are
used for different laptop batteries,,master these methods ,no matter what
problems we can solve.
