Charging the Main Battery
The HomeBase device powers the terminal and fully charges its main battery pack in less than four(4)
hours. To check battery power, see Power on page 6-12.
As battery packs charge, the charging circuitry follows the two-step charging process (CC-CV) that is
recommended for Li-ion batteries. The process monitors changes in temperature, current, and voltage.
Inserting a Terminal
1. Install the battery pack in the terminal; see Install the Main Battery
Pack on page 2-1.
2. Power the HomeBase device; see Powering the HomeBase
Device on page 9-5.
3. Slide the terminal into the terminal well until the Dock LED lights
green to indicate that the terminal is properly seated.
4. The battery pack begins charging.
The intelligent battery charging system in the terminal monitors battery
power and senses when a full charge has been obtained. When
charging is complete, the terminal switches to a trickle charge that
keeps the battery at full charge while resting in the HomeBase device.
