NFORMATION
After unpacking your VX 680 terminal, install the battery and connect the power
pack to the unit for 6 hours.
It is also recommended that the smart battery receive a periodic full discharge. To
ensure a full discharge, use the unit until the battery is fully drained. See
Base Station for more information.
The smart 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.
The VX 680 terminal automatically shuts off when the smart battery reaches the
critically low charge state. If this occurs, the smart 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.
The VX 680 smart 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 buy a new battery (see
information).
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.
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.
Light weight
Lithium is the lightest metal. Thus, lithium-ion batteries enable the manufacture of
lightweight devices.
Long Life
Lithium-ion batteries require low maintenance. They do not exhibit memory
effects, thereby eliminating the need for scheduled cycling to prolong the battery
life.
