Battery Life

Battery Behavior

The terminal uses a single cell, 2450 mAh Li-ion battery (see
Documentation for ordering information). The internal logic of the battery prevents
both overcharging and undercharging—a fault condition where the battery level
goes well below the minimum acceptable charge and the battery becomes
unusable.
The battery has 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 battery is not customer-changeable and therefore should not be
disconnected and removed.
•
Li-ion batteries are not affected by shallow charging. When the terminal has
no external power source or battery, the coin cell battery provides power to the
security circuit.
•
Disconnecting and removing the battery, as well as unplugging the terminal
power pack, reduce the life of the coin cell battery, which does not recharge
and must be replaced when drained.
•
Conserve battery power by turning the terminal off when not in use.
•
Keep the Li-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 micro-USB end of the
power pack to the terminal and plugging the other end of the power pack into a
wall outlet.
See Battery Information
VX 685 terminal keeps track of the charging current going into the battery. The
battery is considered healthy until its capacity is reduced to 70% of the theoretical
capacity. Check the batteries when the number of cycles exceeds 600 full cycles.

The terminal shifts to power pack mode and starts up automatically when the
terminal is connected to a non-battery power source, regardless of the battery
charge state.
