How to Revive Dead Laptop Battery

Typical battery life for laptops and other electronic devices are specified. Usually a battery loses its efficiency after 1 to 2 years of continuous work and can maintain charge for 10 to 15 minutes only. If your laptop battery is also dead before any further action try this trick on your battery. Because it can hold the charge again for 1 to 2 hours and you don't need to pay extra for a new battery.

First keep the dead battery in the freezer for about 14 to 15 hours till it is fully frozen.

Then charge and discharge the battery 3 to 4 times.

Now your laptop battery has a new life and you can use it again.

Maybe you ask yourself how it is possible? It is interesting to know that this is a purely scientific basis, because in general, in different objects due to their natural vibrations of molecules electrical current does not pass easily. This problem is less in conductive objects, because their molecules are placed on a regular basis, so the current can  pass easily. To make an object more conductive you have to make its temperature cooler, so the vibration of molecules will be slower. The thrills never are zero, except at absolute zero (-273°C) which till today still scientists are not able to reach this temperature. This is the reason behind the better working of the CPU in cooler temperature also.

This trick has been tested practically and you can try it yourself. You can even use this method for Hard disk. If you put a Hard disk that does not work in freezer for 10 to 15 hours, then it would be retrieved also.

Note: Put the battery in a plastic bag before you place it in the freezer. After you take the battery out of the freezer, leave it in room for some times and let it get the room temperature. For a battery that has a battery life for 10 to 15 minutes, after freezing, it may work 45 minutes for the first time; and if you continue to charge and discharge it for some times, it would work around 2 hours.
