Innovating Safe and Stable Energy

Safely harness pure lithium energy with Panasonic Lithium batteries. A lightweight, high-energy-density battery optimized for stable discharge in high-drain applications such as tactical flashlights and home security systems. Panasonic Lithium is perfect for continuous or intermittent use over long periods in various devices exposed to wide range of temperatures. This UL recognized battery series has earned a reputation for safety that’s proven by intensive lab tests, such as nail-puncture short-circuit tests, 13-kN crush tests, vibration tests, heat stress tests, and 10-year storage tests. It remains one of the world’s most trusted power sources for specialty high-power applications in harsh environments.

Look Inside
Longer life, trusted reliability
Our High Energy Formula contributes to Panasonic Lithium’s long-lasting endurance in mid and high-drain applications, such as cameras, where the battery’s low internal resistance helps to reduce flash-recovery times for rapid burst shooting. High-purity MnO2 is filled at high density, extending life, while the corrosion-resistant stainless cathode core stabilizes discharge at high voltage. The lithium anode features a special aluminum additive that enhances high-power reactivity, while the Anti-Leak Seal, with durable gasket and use of gas-suppressing materials, helps protect your devices from leakage even in tough operating environments.

B: Special stainless cathode core resists corrosion
C: Aluminum additive enhances lithium reaction‘

Safety system technology
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.

B: Safety valve relieves internal pressure
C: Durable gasket prevents leaks

Reliable in a wide range of temperatures
Various design aspects combine to preserve high capacity after long-term storage while enabling safe use down to -40 °Fahrenheit. Organic materials reduce the electrolyte solidification point to less than other battery types, optimizing storage and operation in low temperatures, while high-purity MnO2 has the optimal particle-size for high-rate discharge at low temperatures. Gas-suppressing materials, meanwhile, preserve capacity after long-term storage at high temperature. Our Anti-Leak Seal and short-circuit protections enhance durability.

Ultra-low self-discharge
Our intensive research yields a more effective choice of electrolyte solvent, which forms a protective film over lithium to prevent ionization and self-discharge while in storage. In addition, calcination treatment conditions were set to prevent MnO2 from leaching into the electrolyte, slowing the rate of self-discharge. Panasonic Lithium batteries boast a self-discharge rate of less than 5% after up to 10 years* when properly stored and unused providing, power when it matters most.

LITHIUM
10-Year* Storage with Quality Assured
Proven battery design, refined materials, special electrolyte solvent, and precise calcination treatment result in a low self-discharge rate during storage. Panasonic Lithium batteries can be safely stored without significant loss of capacity for periods up to 10 years*, with improved resistance to heat and cold compared to other battery types.
*When in an unused condition and stored at room temperature.
