How to Restore a dead or dying laptop/pc battery

How to make you dead laptop battery working again with Freezing Method:

If your laptop/PC battery is dead or is not. Charging up to 100% or it doesn't last longer again, you can get it working again by freezing the battery

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.
