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. 1 Safety Tests 3.1.1 Compression Test 1120 kg No significant electrolyte loss No rupturing 3.1.2 In short circuit condition 24 H, 0.1¦¸ After 24 hours the bottom of the cell is curved by only 0.1mm; diameter unchanged.

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. 6.Do not use with other battery types or old batteries with fresh cells. If different types of batteries are used together, or fresh are used with old ones, the difference in characteristics of voltage, capacity, etc., may cause over discharge of the battery which is exhausted first, leading to swelling, bursting or fire. Http://eemb.com E-mail:[email protected] 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. 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 are used. If swallowed by mistake, consult a doctor immediately. 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 C . Storage in areas with higher temperature, humidity or and is approximately 20¡ã exposure to rain may cause deterioration in battery quality and durability. O 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 Http://eemb.com E-mail:[email protected] 4.Tabs EEMB Company Limited can provide following tabs and leads with the battery, Custom design welcomed.
