Reviving rechargeable batteries often involves a few simple steps. First, clean the battery contacts with a cotton swab dipped in alcohol. Then, fully discharge the battery by using it until the device shuts off. Recharge fully without interruption in a standard charger. If the battery still underperforms, try freezing it. Seal it in a plastic bag and place it in the freezer for 12 hours. Let it thaw to room temperature before charging fully. These steps can help extend the battery life.
