LITHIUM COIN

Powering Tomorrow, Today

Panasonic Lithium Coin batteries provide safe and reliable power in devices essential for daily life. High energy density and high 3 V output voltage support the trend towards device miniaturization. A single Lithium Coin Cell can deliver more power than two or three conventional batteries. Use of organic electrolytes with a solidifying point lower than other battery types makes Panasonic Lithium Coin Cells ideal for use in wide range of temperatures. Backed by 90 years of industry leading technical expertise, Panasonic Lithium Coin batteries have evolved to become one of the world’s most trusted micro-battery for safe, long-lasting power in diverse applications, from household electronics to the IoT devices that energize today’s smart society.

Look Inside

Optimized material formulation

Perfected over years of research, High Power Energy Core features an optimized material formulation that increases energy density, output voltage, storage life, and discharge capacity for overwhelmingly long-lasting performance in high-drain applications as well as in low-drain pulse-discharge applications, such as keyless entry devices. The formula includes a graphite additive to improve manganese dioxide utilization, and a heat-resistant binder for stability in hot conditions.

Technical ingenuity creates the ultimate anti-leak structure

Panasonic’s innovative Anti-Leak Seal is exhaustively lab-tested in real-world appliances. The tough gasket’s rim is embedded in the case and is securely sealed with a custom anode cap and strong adhesive. Enhanced by low-degradation ingredients, our Anti-Leak Seal keeps you and your devices safe.

The secret behind the structure

Our Panasonic Lithium Coin Cells have a unique case design that contributes to its amazing endurance. The concave cathode case and dimpled anode surface increase material adhesion, limit a rise in internal resistance, and support stable voltage and efficient discharge for long-lasting power.

Rigorously Tested for Your Peace of Mind

Panasonic prides itself on the scale of its testing program with the industry’s toughest quality and safety benchmarks. Dedicated facilities simulate operation in heat, cold, and humidity, with batteries also tested for resistance against long periods in storage, impact, pressure, and vibration. Results are used to continually improve battery design.

Child-Resistant Packaging

Warning labels displayed on the package (and stamped on the battery itself) remind you to keep unused batteries secure. Our tamperproof package (authentic sunburst package) meet or exceeds IEC 60086-4 2019, ANSI C18-3M Part 2-2024 Compliance Safety Standards, and CFR 16, Part 1700.20 and CFR 16, Part 1263 as required by Reese’s Law. These initiatives limit chance of accidental ingestion and are a key part of Panasonic’s comprehensive safety system to protect what matters most.
