Batteries
The Boomer II OEM Modem may be powered by batteries if used with
a handheld device.
For battery operated devices, battery selection is a critical decision,
requiring consideration of many factors. These include cell size,
internal impedance, charging requirements, and susceptibility to
common battery phenomena, such as memory effect or overcharging.
Each of these factors is discussed in detail in this section.
The selected battery must be able to meet the Boomer II power
requirements as mentioned previously.
Three prevailing battery technologies exist today:
Nickel cadmium (NiCad) batteries may be used for devices
requiring wide temperature ranges.
Nickel metal hydride (NiMH) and
Lithium ion (Li+) batteries may also be used for devices utilised
above 0ºC. Specifications for these batteries should be obtained
from the manufacturer.
NiCad
Most mature technology
Lower energy density (energy/volume) than NiMH or Li-ion
Available in all cell sizes, including AA, 2/3A, 4/5A, A, 4/3A,
and so on. This represents the greatest number of packaging
options.
Exhibits a memory effect when not occasionally discharged
below the lower extent of its operating voltage. The memory
effect reduces the usable capacity of each battery cell.
Internal impedance of 25-30µΩ per 1.2V cell
Typical cell voltages are 1.2V, with multiple cells used to
obtain higher operating voltages
Can withstand high current pulses, which are characteristic of
packet data applications
Typical charge method is −∆ V (known as negative delta
voltage), which involves charging the battery while looking for
the battery voltage to peak. Then enter a slight overcharge
condition, where the voltage actually begins to decrease prior to
terminating battery charging. NiCad is the most robust battery
technology available today for non vehicular applications.
NiCad can withstand over charging, over discharging, and harsh
environments with reasonable resilience.
Raw battery cells or battery packs can be purchased from
suppliers
