Storage Mode
To store batteries for longer than 8 days, use the charger's storage mode. Each battery will be charged or discharged to 3.8
volts, which is ideal for long-term storage.
To enter storage mode, press and hold storage for 3 seconds until the power LED turns red. The batteries will begin charging
or discharging to 3.8 volts, which may take several hours. The LEDs indicate when the battery is approaching storage voltage
or at storage voltage.
To exit storage mode, press and hold storage. The power LED changes to white and batteries resume charging normally.
Whenbatteriesarereadyforstorage,removethemfromthechargerandplaceinatemperaturecontrolledarea.Recommend
ed battery storage temperature is 10°C (50°F) to 25°C (77°F).
Note: Run storage mode once every 6 months to maintain the storage voltage.
