Use Nickel-plated irn r stainless steel fr the terminals that cntact the battery. Make sure that terminal cntact pressure is 50g minimum, fr a stable cntact. Keep the battery and cntact terminal surfaces clean and free frm misture and freign matter Befre inserting the battery, check the battery cntact terminals t make sure they are nrmal, nt bent r damaged. (Bent terminals may nt make gd cntact with the battery r may cause it t shrt circuit.) When the batteries are piled up in a disrderly way, their psitive and negative terminals may shrt-circuit, cnsuming sme batteries while charging thers, causing them t explde. Lithium batteries that are almst exhausted can utput a vltage that is almst the same as that f a new battery: Please des nt judge a battery nly with a Vltmeter. Avid using a mixture f ld and new batteries; replace all batteries in a set with new ne. Lithium batteries require a perid f time t reach their nrmal vltage again after even a slight shrt circuit. Therefre, shuld the battery is shrt-circuited, wait an adequate lng time fr batteries t recver befre measuring their electrical characteristics. Use a high impedance (1M r higher) vltmeter t measure battery vltage. Battery characteristics vary with type and grade, even when
batteries are the same size and shape. When replacing batteries with new nes, be sure t carefully check the symbls and numbers n them. 6. STORAGE AND MOUNT The cell shuld be preferably stred in dry and cl cnditins. 60 120 days stred cnditin is the equivalent f 6 years at rm temperature (21 ) Buttn lithium batteries need special methd t avid shrt-circuiting befre and after they are installed. As shrt circuits tend t ccur in the fllwing cases, please take care when handing the batteries. 1. Overlapping Batteries A Buttn lithium battery is shaped as shwn belw. It has expsed psitive and negative metallic surfaces with a thin cylindrical seal, called the gasket, in between. Negative terminal Gasket Psitive terminal When batteries are verlapped r mixed tgether in a disrder way, their psitive and negative terminals tuch each ther, causing shrt circuits. 2. Batteries put in a Metallic ntainer r n a Metallic Plate Similar t the verlapping battery prblem, when batteries are put in a metallic cntainer r n a metallic plate, their psitive and negative terminals may shrt circuit thrugh the cnductive surface depending n the placement. 3. When a Battery is Held with Tweezers Metallic Plate When held with a pair f metallic tweezers as shwn belw, the battery shrt-circuits thrugh the tweezers
Metallic Tweezers 4. When Battery Lead Plates Tuch Each Other When battery lead plates bend and tuch each ther r either terminal, the battery shrt-circuits. 5. Slder Bridges Slder may bridge between bard cnductrs, shrt-circuiting and draining battery. 6. Shrt-circuited thugh Sldering Irn Similar t slder bridging, when the circuit bard wiring is shrtcircuited by a sldering irn fr an extended perid, the battery is drained and cnsumed. mplete manual sldering within 5 secnds. 7. Shrts thrugh Piled ircuit Bard When circuit bards with batteries are piled n tp f ne anther, their cnductive traces may tuch, and frm a battery discharge circuit that cnsumes the battery's pwer. 8. Discharge thrugh nductive Electrstatic Preventin Mats nductive mats are widely used t prevent static electricity frm destrying semicnductrs. If a circuit bard with a battery munted in put n a cnductive mat, the sldered cnductrs may tuch the mat, prviding a discharge path fr the battery. 9. Imprper Battery Munting Plarity When the battery's psitive () and negative (-) terminals are backward with respect t the battery munting's plarity marks, the battery may be discharged, depending n the type f electric circuit. 10. Slder When the battery's lead plates are dipped in a mlten slder bath,
the battery is temprarily shrt-circuited. Therefre, cmplete dipping within 5 secnds. 7. SAFETY Battery Handing Precautins t Ensure mplete Safety Lithium batteries cntain inflammable materials, such as lithium and rganic slvents. Imprper battery handing, particularly during transit and strage, may cause heating, explsins and fires. Please strictly bserve the precautins belw in handing lithium batteries. WARNING! 1. DO NOT recharge, shrt-circuit, disassemble, defrm, heat r place the battery near a direct flame. This battery cntains flammable materials such as lithium and rganic slvent and perfrming any f the abve actins culd cause it t ignite explde r becme damaged. 2. Keep this battery ut f the reach f children. If it is swallwed, cntact a physician immediately. 3. When string the battery r thrwing it away, be sure t cver it with tape. If the battery cmes int cntact with ther metal bjects, it culd ignite r becme damaged. AUTION! lsely bserve the fllwing precautins. If the battery is used incrrectly, it culd leak r becme damaged, causing device truble r injury. 1. Insert the battery with the "" and "-" ends crrectly riented. 2. If the battery is used tgether with new batteries, d nt use it with a different type f battery. 3. D nt apply slder directry t the battery. 4. Avid string the battery in direct sunlight, r in excessively ht and humid lcatins. 8.
