Hazard Warning
1 Forbid Disassemble Batteries The battery has protective component and circuit internally to avoid danger. Mishandling such as improper disassembly will destroy its protective function and make it heat, smoke, distort or burning.
2 Forbid Short-circuit Batteries Do not touch the plus and minus contacts with metals. Do not put the battery with metal element together in either storage or movement. If the battery is short-circuit, it carries magnified current,which will cause damage and make the battery.
