• Step 3: Put the battery in the freezer for at least 12 hours - be sure to record the start time for the refrigerator. You can even leave the battery in the refrigerator for 72 hours.

• Step 4: Take out the battery from the freezer. Do not need to hurry to take the battery out of the plastic bag, you put the plastic bag (don’t take out the battery from plastic bag) out of normal air and add 10 hours more until it reaches the temperature in your room.
• Step 5: As soon as the battery pack temperature has dropped to room temperature, remove the battery from the plastic bag, open the towel and clean the battery with a dry towel until there is no more moisture on the battery.
