x
The V 670 terminal uses an Li-ion smart battery (see
Documentation for ordering information). The internal logic of the smart battery
prevents both overcharging and undercharging (a fault condition in which the
battery level goes well below the minimum acceptable charge and the battery
becomes unusable).
x
The 670 terminal will operate on battery power or on power pack power. The
V
smart battery charger in the terminal will be active whenever the power pack is
connected.
The following are features of the smart battery:
•
Two Li-ion cells
•
A fuel gauge module that:
•
monitors state of charge (voltage and percentage of capacity),
•
communicates with the terminal (charge parameters and status),
•
determines full charge capacity (on charge cycle and uninterrupted
discharge cycle), and
•
automatically shuts down when cell voltage is extremely low.
•
A safety circuit that:
•
prevents cell damage from overcharge, over-discharge, or overheating,
and
•
activates when the battery is left in an unused terminal for extended
periods.
•
Lithium-ion batteries are not affected by shallow charging. Furthermore, when
the terminal has no external power source or smart battery, the coin cell
battery provides power to the security circuit.
•
Uninstalling the battery and unplugging the terminal power pack reduce the
life of the coin cell battery, which does not recharge and must be replaced if
drained.
•
Conserve battery power by turning the V
the terminal is not to be used for an extended period of time, keep the Lithium-
ion battery inserted in the terminal, and power up the terminal periodically to
check the battery charge. Do not let the battery charge fall below 10% for
extended periods of time as this may permanently diminish the battery
capacity. Recharge the battery by attaching the power cord to the terminal and
plugging the power pack into a wall outlet.
