Laptop batteries are one expensive piece of equipment.So if you have an old laptop that works just fine, but need to spend Rs. 2000 upwards just to replace the battery and bring the laptop back to life, here we at Abijita Foundation have brought you one trickiest way to bring life back to the dead battery.

You can add new life to your NiMH or NiCD laptop battery by placing it in a tightly-sealed plastic bag and freezing it for 12 hours. If you have a Lithium Ion or Lithium Polymer battery, however, freezing it is actually dangerous. Instead, consider doing a battery calibration, which will both restore and prolong your battery power. While these methods won’t make your battery as good as new (you may only gain about thirty minutes of extra charge time from an older battery that no longer holds a charge), they will help you get the most of your battery until you can buy a new one.
