It seems every day there are new items available that use rechargeable batteries. We know that rechargeable batteries will not last indefinitely, but there are ways to extend their usable life span. All it takes are some simple techniques.

Learning to recondition rechargeable batteries will not only save you money, it will also help save the environment. Most of the batteries in use can be restored, below are some ways to restore rechargeable batterie your laptop battery.

The first step is to identify the type of battery in your laptop. The type will be printed somewhere on the case. You will find you have a Nickle Cadmium (NiCd), Nickle Metal Hydride (NiMH) or Lithium Ion (LiON).

If it is the NiCd or the NiMH then you can use this technique. If it's the LiOn do not try this as it may damage the battery.

What happens with these two battery types is they can suffer from memory effect. This means they will remember the point that you typically recharge them. They will set this as the base point and will eventually reduce the amount of charge the battery will take. What results is a battery that never fully recharges.

To reset the battery and remove any memory effect, try one of these techniques. The first method to fully discharging the battery in your laptop is to turn it on and enter into the setup screen. You should be able to push Del after you switch it on. Let your laptop sit in this mode until it switches off due to low power.

Next place the battery in a zip lock bag and place in your freezer overnight. The gel in the battery will cool down and this will help remove any memory effect that it may have. After you remove it from the freezer allow it to return back to room temperature then return it to your laptop.

Discharge and freeze the battery two more times and you will see a greater improvement in your batteries performance.
