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 temperaturecontrolled 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.
Restoring Factory Settings
Press and hold reset to restore factory settings. All LEDs will flash and turn off as the charger reboots.
IP addressing will be set to automatic, and charger will be in charging mode.
Network Connections
Use Ethernet cables to connect chargers to a network to monitor charging, battery health, and other parameters.
For most installations, use a star network topology with an Ethernet switch. For smaller installations, you can connect chargers
to each other in a series.
