The V

x

680 terminal uses a Li-ion smart battery (see 

 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). 

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.

The 

V

x

680 terminal will operate on battery power or on power pack power. The 

smart battery charger in the terminal will be active whenever the power pack is 
connected.

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

x

680 terminal off when not in use. If 

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 cable to the terminal 
and plugging the power pack into a wall outlet.
