Panasonic’s exclusive safety structure prevents short-circuits and leaks with fail-safe protections for over-current, over-voltage, and overheating, even if the battery is damaged. The system includes a thermosensitive PTC that detects temperature rises and increases resistance to prevent short-circuit, a built-in safety valve to relieve internal pressure, and durable gasket material that’s effective at preventing leaks. Panasonic Lithium batteries are UL recognized.
