Taking care of the battery is very important to ensure the performance and life span is optimal. When the battery is not in use, be sure that it is placed in room temperature and fully charged. Do not let a depleted battery sit there for long periods of time.
The great thing about the battery is that you can always use it! If its not cold out, take the battery along with you on your trips and adventures or just out with you to help you keep your devices charged up and running when they are low on juice.
