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 over discharging can occur. 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 1% of the nominal battery capacity over the total period of use.

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 position. 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 shortcircuits. 5 . older 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. -5- 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 shortcircuited. Therefore, complete dipping within 5 seconds. ■ Handling Precautions 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. PRECAUTIONS 1. Do not put the battery into microwave over or drying machine. 2 .Do not drop, apply excessive damage or deform the battery. ■ 3 . Do not mix the used battery together with the new battery or different type of batteries. 4 . 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. -6-
