    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.  
    Http://eemb.com E-mail:global@eemb.com  
    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.
