Instructions.Things You'll Need:
A battery charger with discharge capabilities.
1.1
Place the dead battery in your freezer (yes next to your ice cubes). Allow the battery to remain in the freezer for several hours.
2.2
Remove the NiCD or NiMH battery and place it in your battery charger. Immediately place the battery in the discharge cycle. Allow the battery to fully discharge what is left.
3.3
Immediately after discharge, begin a charge on the battery. Allow the battery to charge for at least 24 hours.
4.4
Remove the nickle cadmium (Ni-CD) or nickel metal hydride (NiMH) battery from the freezer, and insert into your charger again. Begin the discharge process.

Allow the battery to fully charge over 24 hours. Discharge again. What you are doing is called "Cycling" your battery, which is like doing a workout to make your battery stronger.

Repeat the charge & discharge cycle at least 5 times. After the 5th time, your NiCD or NiMH battery will most likely work again. Continue the cycle process to give the battery more strength.
