V. Construction
VI. Battery Selection
Component Class Batteries and Cells
Today’s circuit designers recognize the capabilities
of BR Lithium coin cells and FB batteries to function
as permanent components in their circuits.
FB batteries exhibit reliability rates similar to diodes
and resistors.
The combination of very low power Complementary
Metal-Oxide Semiconductor (CMOS) memory
devices with high energy, long life batteries now
allow for batteries to be used as life-of-product
components.
The traditional approach to product design is to
provide sufficient energy to meet a design target
for a stated period, at which time the batteries
would be replaced. The decision to provide
component or expendable power is fundamental to
the product concept of the device being powered.
Component batteries allow the designer to increase
the reliability and functionality of the device by
eliminating the need for consumer replacement
of batteries. Component batteries eliminate the
problems of reversed polarity, wrong chemical
system, mismatched capacities, and higher
operating costs. However, component batteries
require careful selection. The batteries must assure
adequate energy for the expected load to compen-
sate for self-discharge and the thermal environment
expected, and the batteries must also have a high
reliability connection to the circuit.

Today’s demand for high performance, small
footprint, reliable, and cost-effective electronic
products can be realized by identifying the best
match between the battery and its application.
To do so requires a good understanding of the
device’s power requirements and the environment
in which it is used as well as how the battery reacts
to those loads and environments.
It is important that the battery be considered early
in the design process. This will allow the optimiza-
tion of battery life through the selection of power
conserving circuit components. Moreover, early
battery selection will also minimize circuit and
mechanical layout changes later in the design process.
The following is a list of basic application
characteristics and conditions that must be
considered for an optimum selection of a lithium
Carbon-monofluoride power source.
