Battery Information
The terminal uses a high-capacity Lithium-ion battery pack. 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).
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. Recharge the battery to restore operation.
Advantages Lithium-ion batteries have numerous advantages over other types of rechargeable
batteries.
High energy density
Lithium-ion batteries have twice the energy density of standard nickel-cadmium
batteries. This means they can store more energy than other rechargeable
batteries.
Light weight
Lithium is the lightest metal enabling 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.
Does Not Require Prolonged Initial Charging
Unlike their nickel-cadmium counterparts, lithium-ion batteries do not require
prolonged initial charging. A regular charge cycle is enough.
NOTE
The terminal operates on battery power or on power pack power. The battery
charger in the terminal remains active whenever the power pack is connected.
NOTE
The terminal automatically shuts off when the battery reaches the critically low
charge state. If this occurs, recharge the battery for a minimum of 30 minutes
before it can power the terminal. A safety circuit that has been discharged below
its critical state may take several recharge attempts to reset.
