Lithium Carbon-monofluoride
(BR) Coin Cells and FB
Encapsulated Lithium
Coin Cells
I. Introduction
Lithium has become a generic term representing a
family of battery systems in which Lithium metal is
used as the active anode material or negative elec-
trode. Variations in the cathode material, or positive
electrode, and the cell electrolyte result in hundreds
of possible combinations of Lithium batteries.
Rayovac Lithium Carbon-monofluoride (BR)
batteries are a solid-cathode type which optimizes
reliability, safety, cost and performance.
II. Features
• Outstanding shelf life and excellent performance
over a wide temperature range
• Stable discharge voltage
• High energy density and voltage (3V)
• Enhanced safety by the use of Carbon-mono-
fluoride electrode material and a non-corrosive,
non-toxic electrolyte
• Excellent leak resistance
• Shelf life of ten years or more
• Pre-tinned terminals are solderable
• Available with many wave-solderable terminal
configurations
III. Quality Systems Certification
IV. Applications
The following devices are examples of good uses
for BR coin cells:
• Computer Memory and Real Time Clock Backup
• Electronic Counters, Process Controllers
• Portable Instruments
• Time/Data Protection
• Industrial Controls
• Electronic Gas, Water and Electric Meters
• Communication Equipment
• Tire Pressure Monitoring Systems (TPMS)
• RF Tags, Toll Tags, and ID Tags
• Portable Electronic Devices
Application Considerations
Rayovac BR coin cells and batteries should be
considered for applications that are characterized
by a need for:
• Miniaturization
• Leakage resistance
• Lightweight
• Shock and vibration tolerance
• Low to moderate current drains
• Environments requiring extended operation or
storage at a wide range of temperatures
• The need for flat discharge voltage and consistent
source impedance
• Long shelf life
• An extended service life due to low self-discharge
rate
• Enhanced safety and reduced product liability
concerns
• U.L. recognized components
