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.

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.

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.
