Safety Guidelines

Conditions of Acceptability
The use of these cells may be considered
generally acceptable under the conditions given
below:

1. The cells are identified in accordance with
"Marking" as described below.

2. Unless the conditions of Par. 2A are met, these

batteries are to be used only in devices where
servicing of the battery circuit and replacement of
the lithium battery will be done by a trained
technician.

2A. All of these batteries are acceptable for use in
user-replaceable applications when used in
accordance with the following except for Model
CR2477N:

2A.1 The end product must be designed to
prevent reverse polarity installation of the battery,
or if the battery is reversed, the short- or open
circuiting of any protective component, one
component at a time, shall not result in forced-
discharge of the battery.

2A.2 The end product shall contain a warning
notice adjacent to the battery stating the
following: "Replace Battery With (Battery
Manufacturer's Name or End-Product
Manufacturer's Name), Part No. ( ) Only. Use of
another battery may present a risk of fire or
explosion. See owner's manual for safety
instructions".

2A.3 The instruction manual supplied with the end
product shall also contain the above warning
notice along with instructions to the user as to
where replacement batteries can be obtained. The
instruction manual shall also contain the following
additional warning notice: "WARNING, Battery
may explode if mistreated. Do not recharge,
disassemble or dispose of in fire."

3. These cells are intended for use at ordinary
temperatures where anticipated high temperature
excursions are not expected to exceed 100°C
(212°F).

4. These cells can be used in series up to a
maximum of four cells of the same model
number. When used in series, there should be
instructions adjacent to the cells stating that when
the cells are replaced, they should all be replaced
at the same time using fresh cells only. These
cells should not be connected in series with any
other (other than the allowed number of cells in
series) power source that would increase the
forward current through the cells.

5. The circuit for these cells shall include one of
the following:
A) Two suitable diodes or the equivalent in series
with the cells to prevent any reverse (charging)
current. The second diode is used to provide
protection in the event that one should fail. Quality
control, or equivalent procedures, shall be
