Please read and observe the follwing precautions thoroughly.
Lithium Manganese Dioxide Battery contains flammable materials, such as organis solvent. Improper battery handling may cause leakage, heating, explosion or ignition of the battery, which may lead to injury or product failure |
|
 |
|
 |
Never charge the battery. Charging the battery may cause seethe of the battery electrolyte or increase of the battery internal pressure. Leakage, heating, explosion or ignition of the battery may be caused as a result of it. |
|
|
Keep away from infants. If infant happens to swallow the battery, consult a doctor immediately. |
|
|
In case of eye contact with the battery electrolyte, immediately flush eyes thoroughly with water, and consult a doctor. |
|
|
In case the battery electrolyte happen to come into mouth, gargle well enough and consult a doctor immediately. |
|
|
Do not heat or disposed in fire or water. Do not modify or disassemble the battery. It may damage the gasket, and may cause ignition, heating, leakage or explosion. |
|
|
Do not short-circuit positive (+) and negative (-) terminals. Keep away from metal or other conductive materials. Jumbling the batteries of direct contact with positive (+) and negative (-) terminals and metal or other conductive materials may cause short-circuit. |
|
|
When the battery is stored or disposed, isolate positive (+) and negative (-) terminals of the battery to avoid those terminals touch each other. |
|
|
Insert the battery with positive (+) and negative (-) terminals correctly oriented. |
|
|
 |
|
|
Do not put the battery into microwave over or drying machine. |
|
|
Do not drop, apply excessive damage or deform the battery. |
|
|
Do not mix the used battery together with the new battery or different type of batteries. |
|
|
Do not store the battery in high temperature and high humidity location and where the battery is exposed to sunlight to avoid performance deterioration, swelling or leakage, of the battery. |
|
|
|
 |
|
|
A primary lithium battery is not rechargeable. When used for memory backup in combination with another power source, current may flow into the battery from the other source.
To prevent this, include a protection diode and resistor in the circuit so that no battery charging or overdischarging can occur. |
|
| 1. |
Allowable Range of Diode Back-Leakage Current |
|
To prevent the battery from being charged by the main power source, be sure to use a back-current prevention diode and a protection resistor. Select a silicon diode or a Schottky diode with minimum leakage current, and design the circuit so that the amount of charging due to leakage current does not exceed 2% of the nominal battery capacity over the total period of use. |
|
|
|
|
| 2 |
Maximum Allowable Charge Current to Battery |
|
A protection resistor is needed to prevent diode failure from allowing a large current to flow into the battery. The following table shows the maximum allowable charging current in the event of diode failure. |

 |
|
| Protection resistance R must exceed the value calculated in the following formula: |
 |
| * In this equation, the worst-case battery voltage (0) is assumed. |
|
|
|
|
 |
|
|
| To use the battery efficiently, observe the following precautions. |
|
|
Do not solder the battery directly. Excessive heating may cause deformation of the battery components such as the gasket, which may lead to the battery swelling, leakage, explosion or ignition. |
|
|
Observe the soldering condition for the tabbed battery to be specified by the manufacturer. Choose the tabbed battery if soldering is required.
Excessive heating may cause deformation of the gasket, leakage or performance deterioration of the battery.
Assure not to exceed the battery temperature higher than 60°C at soldering. |
|
|
Use nickel-plated iron or stainless steel for the terminals that contact the battery. |
|
|
Make sure that terminal contact pressure is 100g minimum for stable contact. |
|
|
Keep the battery contact terminal surfaces clean and free from moisture and foreign matter. |
|
|
Before inserting the battery, check the battery contact terminals to make sure they are normal, not bent or damaged. Bent terminals may not make good contact with the battery or may cause it to short-circuit. |
|
|
Do not overdischarge the battery lower than 0V. It may lead to reversed polarity and cause ignition, heating, leakage or explosion. |
|
|
Lithium Manganese Dioxide Battery that is almost exhausted still maintains high output voltage that is almost the same as that of a fresh battery. Avoid using a mixture of old and new batteries; replace all batteries in a set with new ones.
|
|
|
Lithium Manganese Dioxide Battery requires considerable time to regain their normal voltage after even a slight short-circuit. Therefore, should the battery be short-circuited, wait an adequate time for the battery to recover before measuring its electrical characteristics. |
|
|
Use a high impedance (1M or higher) voltmeter to measure battery voltage. |
|
|
Battery characteristics vary with type and grade, even when batteries are the same size and shape. When replacing batteries with new ones, be sure to carefully check the symbols and numbers on each battery. |
|
|
Please design equipment so that infants cannot easily remove batteries and swallow them. |
|
|
Consult the sales representative, when series or parallel connection of several batteries is required. |
|
|
 |
|
|
| Unlike other electronic components, Lithium Manganese Dioxide Battery(Coin-type) may be externally shortcircuited before and after it is installed in circuit boards and without the power being turned on. This causes power drainage. As a result, the battery may lose its capacity before the equipment is even used. As short-circuits tend to occur in the following cases, please take care when handling the battery. |
|
| 1. |
Overlapping Batteries |
|
Lithium Manganese Dioxide Battery is shaped as shown below. It has exposed positive(+)and negative(-) metallic surfaces with a thin cylindrical seal, called the gasket, inbetween them. When the batteries are overlapped or mixed together in a disorderly way, their positive(+)and negative(-)terminals touch each other, causing short-circuits.
 |
|
| 2. |
The Batteries Put in a Metallic Container or on a Metallic Plate |
|
Similar to the overlapping battery problem, when the batteries are put in a metallic container or on a metallic plate, their positive(+)and negative(-)terminals may short-circuit through the conductive surface, depending on how the batteries are positioned.
 |
|
| 3. |
When The Battery is Held with Metallic Tweezers |
|
When held with a pair of metallic tweezers as shown, the battery short-circuits through the tweezers.
 |
|
| 4. |
When The Battery Lead Plates Touch Each Other |
|
When the battery lead plates bend and touch each other or other either terminal, the battery short-circuits.
 |
|
| 5. |
Solder Bridges |
|
Solder may bridge between circuit board conductors, causing a short-circuit and draining the battery.
|
|
| 6. |
Short-circuits through Soldering Irons |
|
Similar to solder bridging, when the circuit board wiring is short-circuited by a soldering iron for an extended period the battery is drained and consumed. Complete short-circuits through soldering irons within 5 seconds. |
|
| 7. |
Short-circuits through Piled Circuit Boards |
|
When circuit boards with the batteries are piled on top of one another, their conductive traces may touch and form a battery discharge circuit that consumes the battery's power. |
|
| 8. |
Discharge through Conductive Electrostatic Prevention Mats |
|
Conductive mats are widely used to prevent static electricity from destroying semiconductors. If a circuit board with mounted battery is put on a conductive mat, the soldered conductors may touch the mat, providing a discharge path for the battery.
|
|
| 9. |
Improper Battery Mounting Polarity |
|
When the battery's positive (+)and negative (-)terminals are reversed with respect to the battery mounting's polarity marks, the battery may be discharged, depending on the type of electric circuit. |
|
| 10. |
Solder |
|
When the battery lead plates are dipped in a molten solder bath, the battery is temporarily short-circuited.
Therefore, complete dipping within 5 seconds. |
|
|
 |
|
|
| Following the UN recommendations, the new regulations became effective as of January 1, 2003 regarding the transportation of lithium batteries.
|
|
| A lithium cell that contains lithium metal no more than 1.0g can be treated as non-dangerous goods by the United Nations Recommendations on the Transport of Dangerous Goods/Special Provision 188, provided that the products are prevented from being short-circuited each other and are packaged in an appropriate manner securing toughness during transportation. |
|
| The International Civil Aviation Organization (ICAO), for air transportation, takes the UN Recommendations specified above as it is and prescribes the Special Provision A45. The International Air Transportation Association (IATA), follows the ICAO/Special Provision A45, accordingly. The provisions are set by U.S. Department of Transportation (DOT), for land, sea and air transportation, are based on Special Provision 188 of the UN Recommendations. |
|
| Sony Lithium Manganese Dioxide Batteries are all applicable to the UN Recommendations/Special Provision 188 (Special Provision A45 of the ICAO Technical Instructions) and can be transported as 'non-dangerous goods'. |
