Warnings for accident prevention in handling battery
WARNING: Fire, Explosion, Leakage and Burn Hazard. Do not recharge, Disassemble, Heat Above 212°F, Incinerate, Or Expose Contents To Water. Be Sure The Battery Is Inserted In The Right Direction. The lithium battery incorporates inflammable substances such as lithium and organic solvent, etc. inside. If the lithium battery is handled in a wrong way, it may cause injury, fire and other dangerous accident caused by heating, bursting, firing, etc. Be sure to follow the instructions mentioned below to prevent you from an unexpected accident before unpacking, in and after using the battery.
1. Be careful of short-circuit. If the positive (+) and negative (-) terminals come into contact with each other or with other metallic material, the battery is shortcircuited. If many batteries are left disorderly and their terminals are in contact with others, some of the batteries may generate heat, burst or fire and resultingly cause accident. Neither immerse battery in water nor throw it into fire. If the lithium battery is immersed in water or thrown into fire, it may fire or burst violently. Avoid heating the battery. If the lithium battery is heated at a temperature of 100°C or more, the electrolyte may leak from the battery because the plastic materials such as gasket and separator are damaged or the battery may burst or fire because the battery is heated by internal shortcircuit. Avoid directly soldering the battery. If the lithium battery is directly soldered, the electrolyte may leak from it because the plastic materials such as the gasket and separator are damaged or the battery may burst or fire because it is heated by internal shortcircuit. Avoid charging the battery. If the primary battery is charged, the battery may generate gas inside and it may resultingly cause expansion, burst or fire of the battery. Avoid dismantling the battery. If the lithium battery is dismantled, some kind of gas is generated and it stimulates the throat or the dismantled battery may fire because the negative lithium reacts on water and generates heat. Avoid deformation with pressure. If the lithium battery is deformed with pressure, the electrolyte may leak from it because of warp or damage in the sealing, or the battery may burst or fire because it is heated by internal shortcircuit. Don�t use batteries of different types or old ones mixedly. If batteries of different brands/types are mixedly used or new and old batteries are mixedly used, it may cause expansion, burst or fire of the batteries because they are over-discharged by difference in their characteristics of voltage, capacitance, etc. Avoid setting of the battery in wrong polarities. If the battery is set in wrong polarities (+ and - poles are set reversely), the battery may be shortcircuited and it may resultingly cause heating, bursting or firing in the battery.
