19. Battery Life Calculation
The following data are provided in this section:
-
Basic Current Consumption
This is the current consumption with all devices or functions (except for LCD) disabled. This is
equivalent to the condition when the unit is turned ON and waiting for key pressing.
-
Additional Current Consumption
This is increase in current consumption when a built-in device or function is activated
additionally.
Current consumption with a device activated is given as the sum of Basic Current Consumption
and Additional Current Consumption. The goal of this subsection is to calculate battery life by
using these data. Example of battery life calculation (in Typical Operational Pattern) is also given
at the back of this section.
BASIC CURRENT CONSUMPTION
=
100 mA
Condition: LCD=ON, Backlight=off, Vibrator=off, Bluetooth=off, Wireless LAN=off
NOTE: The wireless LAN (SS transceiver) can take three states: transception (TX/RX), reception
(RX) and intermittent reception (off). When the wireless LAN has no data to transmit or
receive, it repeats reception intermittently for power saving. “Wireless LAN=off” means
this condition.
ADDITIONAL CURRENT CONSUMPTION
ADDITIONALLY-DRIVEN DEVICE
ADDITIONAL CURRENT CONSUMPTION
Laser Scanner
30 mA
Wireless LAN (RX)
280 mA
Wireless LAN (TX/RX)
NOTE: Each time “Wireless LAN
(TX/RX)” completes,
“Wireless LAN (RX)” is
performed for one second
automatically.
440 mA
Buzzer (Volume=High)
50 mA
Bluetooth (Communicating)
100 mA
Bluetooth (Linked)
15 mA
LCD Backlight (High)
100 mA
LCD Backlight (Medium)
60 mA
LCD Backlight (Low)
30 mA
Vibrator (Activated)
110 mA
NOTE: The above-listed data were collected by factory-test under the following conditions:
- Ambient Temperature:
20 to 25°C
- Battery Pack used:
Brand-new BP-12000-W battery pack which was fully charged in
20°C
by using BC-12000-W battery charger.
