Charging Tips for Maximum Performance
•Store and charge the unit where temperatures are between 50˚ F (10˚ C) and 100˚ F (38˚ C). Storing the unit or batteries above 100˚ F (38˚ C) will reduce battery life.
•Storage below 50˚ F (10˚ C) will not reduce battery life, but may require a longer charging time.
•Store the unit on the charging station when not in use. The unit is designed so that the battery cannot be overcharged.
