DIY Method of Restoring a Dying or Dead Laptop Battery

Hello friends,
let me take you back to the King James version of restoring your laptop battery
because some how someday, if you are not already experiencing this, your laptop
battery will wear out. The battery that normally last you for 4hours will be
automatically be reduced to 30min or an hour. While some laptops are already
acting as a desktop (you can’t use except its connected to electricity).

But I’m a good guy so I’ll show you two method of
restoring your laptop battery.
1. Re-calibrating Method:
This method works better if your battery never charges to
100% (no matter how you charge it, it always stop at 90+%) or if the OS says
you have 25 min of battery remaining, but the computer dies either much sooner
or much later. 
DIY Method of Re-calibrating Your Laptop Battery

Step 1: Charge your battery to 100% or
to whatever max percentage it can reach and leave it there for about 2 hours to
cool down.

Step 2: Now disconnect the power and
let the battery drain. There seems to be two views about how to do this. You
can either let the battery run down all the way until the laptop dies or you
can set it so that it goes to sleep or hibernates around 3 to 5%. Either way,
you want to make sure the display stays on until it either dies or goes to

Step 3: Let the computer remain turned
off for anywhere between 3 to 5 hours.

Step 4: Turn it back on and let it
charge all the way to 100%.

2. Freezing Method:

This sound crazy but it works
like charm. Even a smartphone battery tends to last longer when its under a
cool environment than when it’s under the scorching sun.

Step 1: Take your battery out and place
it in a sealed Ziploc or plastic bag.

Step 2: Go ahead and put the bag into
your freezer and leave it there for about 12 hours. Some people suggest leaving
it for longer, but I wouldn’t leave it for more than 24 hours.

Step 3: Once you take it out, remove
the plastic bag and let the battery warm up until it reaches room
temperature. Be sure to wrap it in a towel and wipe away any condensation as it
warms up.

Step 4: Reinsert the laptop battery and
charge it completely.

Step 5: Once charged, unplug the power
and let the battery drain all the way down.

Now repeat steps 4 and 5 at least
4 times: charge all the way to full, and then discharge completely. After this,
you should see a dramatic turnaround in your battery cells.

Note: this method works best on NiCD
or NiMH batteries. Do not try this on lithium battery.

Finally, Make sure you unplug
your charger once your laptop charges to 100%… leaving it plugged in after
fully charge kills the battery cells.

  1. As far as I know, 98% of rechargeable batteries are lithium nowadays, smartphone and laptop makers hardly use NiCD or NiMH battery.

    I kinda find this post irrelevant.
