3. General Design Characteristics
In order to ensure optimum battery performance for the primary CR cylindrical cells,
we suggest consideration of the following design-in requirements. They are the
nominal and operating voltage, load current and profile, the duty cycle,
temperature requirements and shelf life for the application. These characteristics
for each battery type must be evaluated against the design requirements to select
the most appropriate product that fulfills these requirements.

3.2 Safety Guidelines
Safety and Handling Issues
We recommend that attention begins to the design and implementation of our
lithium-Manganese Dioxide cells to ensure superior operating performance. With
our Lithium-Manganese Dioxide Batteries, the appropriate precautions must be
taken to avoid physical and electrical abuse otherwise, the batteries can be
hazardous if not used properly. To avoid such incidents, we would suggest you
review the following safety and handling precautions for your potential applications:
1.Do not heat. Nor dispose of in fire.
If heated the plastic materials in the cell such as the gasket and separator may be
damaged, causing leakage. The heat generated by a short circuit inside the
batteries may lead to bursting or combustion. If disposed of in fire, batteries my
violently rupture.
2.Do not charge (Lithium Primary Battery CR Series).
When a Lithium Primary Battery is charged, gas is generated inside the battery and
can result in swelling, heat generation, leakage, violent rupture or potential fire.
3.Avoid forced discharge.
When batteries are force-over discharged with an external power source, the
voltage drops to under 0.0 V (reverse electrode), and inner gas is generated. This
can lead to swelling, heating, leakage violent rupture and / or potential fire.
4.Do not short circuit.
If the positive and negative terminals come into contact with each other or with a
metal object, this can cause a short circuit, generating heat. If the batteries are
stacked on top of each other or mixed, the resulting short-circuit can lead to heat
generation, leakage, violent rupture or fire.
5.Do not disassemble, apply excessive pressure or deform.
If a battery is forcefully disassembled, gas may be generated which may cause
throat irritation, or the lithium metal may generate heat, causing fire. If deformed
under pressure or under impact, distortion of the seal may lead to leakage, or a
short circuit inside the battery may lead to potential safety hazards.

7.Observer the (+) and (-) polarity.
If the batteries cell polarity is reversed by inserting the battery backwards,
depending on the equipment, a short circuit or over discharging may result a
potential safety hazard.
Are used. If swallowed by mistake, consult a doctor immediately.
8.Do not swallow
store batteries in a safe location, out of the reach of babies and small children. Also,
make sure that batteries can not be easily removed from equipment in which they
9.Do not throw into the water.
This can result in corrosion and the generation of combustible gas.
10.Do not store in direct sunlight or rain.
Store batteries in a place not subject to direct sunlight. Make sure the area is dry
and is approximately 20 C. Storage in areas with higher temperature, humidity or
exposure to rain may cause deterioration in battery quality and durability.
11.Soldering.
Do not solder or weld directly to the cells surface. Use preassembled cells with tabs
or leads.
3.3 Transportation of EEMB Lithium Cells
Lithium cells are considered non-dangerous if each battery with a solid cathode
contains 1 gram or less of lithium and are therefore not subject to national or
international dangerous goods regulations for transport by road, rail, sea, or air,
provided that
1.Batteries are separated so as to prevent short circuits.
2.Batteries are packed in strong packaging, except when installed in electronic
devices.
3.Details of specific transport regulations are available on special request.
All EEMB Lithium Cells listed above contain less than 1.0 gram of Lithium and, as
long as they are packed as above, are therefore not subject to the dangerous goods
regulations.
