VX 675 Battery Information
Battery
The VX 675 terminal uses a Lithium-ion battery. The internal logic of the 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 VX 675 comes with a high-capacity battery pack.
Charging
The battery has a safety circuit to protect the Lithium-ion cells from overcharging
and over-discharging. If the battery is over-discharged, the safety circuit shuts
down the battery. The battery must then be recharged to restore operation.
Battery Life
The VX 675 battery can be charged and discharged hundreds of times, but will
eventually wear out. When operating times are noticeably shorter than usual, it is
time to order a new battery.
Advantages
Lithium-ion batteries have numerous advantages over other types of rechargeable
batteries.
High energy density
Lithium-ion batteries typically have twice the energy density of standard nickel-
cadmium batteries. This means that for their size or weight they can store more
energy than other rechargeable batteries.
NOTE
The VX 675 terminal will operate on battery power or on power pack power. The
battery charger in the terminal will be active whenever the power pack is
connected.
NOTE
The VX 675 terminal automatically shuts off when the battery reaches the
critically low charge state. If this occurs, the battery must be recharged for a
minimum of 1/2 hour before it can power the terminal. It may take several
recharge attempts to reset the safety circuit that has been discharged below this
critical state.
WARNING
Do not dispose of batteries in a fire. Lithium-ion batteries must be
recycled or disposed of properly. Do not dispose of Lithium-ion
batteries in municipal waste sites.
