Choosing a Battery Wisely

High Energy Formula

High Energy Formula uses refined materials supplied to us exclusively. Cathode features high-purity MnO2 with a titanium additive for smooth discharge and extended storage life, while a new surfactant revitalizes zinc reaction to efficiently sustain power in high-drain devices.

Note: Titanium added to AA/AAA sizes in select countries/regions only.

Unique Anti-Leak Seal Technology

Anti-Leak Seal Technology combines a refined structural design and a unique gas-suppressing formula to reduce the chance of leakage, whether batteries are in use or in storage. Exclusive Seal Structure employs a thin gasket with a tough material that’s locked tight into the battery can wall, capped with a metal seal, and secured with adhesive. Our Gas-Suppressing Formula, meanwhile, uses proprietary materials that suppress gas generation, reducing pressure buildup and the chance of leaks.

Store Safely for up to 10 Years*

You can safely store Panasonic Alkaline Plus Power batteries for up to 10 years*. Unique high-quality chemistries, including added titanium, prevent degradation while Anti-Leak Seal prevents leakage to ensure long-life stability. Enjoy the powerful Panasonic Alkaline Plus Power performance whenever you need it.

*With AA/AAA batteries in an unused state and properly stored. C,D, and 9 V batteries excluded.

Note: Titanium added to AA/AAA sizes in select countries/regions only.

Special Tough Coating

Does your device work intermittently? This may be due to contact resistance, when nickel flakes off the battery terminal and interrupts the flow of electricity to your device. Panasonic’s original Special Tough Coating is a nickel-iron alloy that reduces contact resistance, optimizing energy flow and keeping your appliances working at their best.

Note: 9 V batteries excluded.

Special Tough Coating is a nickel-iron alloy technology that maintains a smooth flow of power from battery to device.

Tough Zinc-Alloy Can

Panasonic Super Heavy Duty batteries combine advanced engineering technologies with high quality at a low cost. A key feature is the tough zinc-alloy can, which is not only stronger but also more resistant to corrosion. Best of all, no lead is added to the eco-friendly zinc-alloy can for safe and convenient disposal and greater peace of mind.

Anti-Leak Protection

Your devices are protected by the most advanced anti-leak battery technology with Panasonic Super Heavy Duty batteries. Structural weak points in conventional carbon zinc battery structure makes them prone to leakage. Panasonic’s robust design incorporates a stronger collector-rod sealing structure together with nylon inner-tube protection and a metallic outer can. The result is a far lower chance of structural failure and leakage.

Zero Lead*, Cadmium, or Mercury Added

Panasonic released its first mercury-free battery back in 1991. Now, it’s among the first manufacturers in the world to completely eliminate the use of lead* in its carbon zinc batteries. Panasonic Super Heavy Duty batteries have no added lead, cadmium, or mercury*. This gives peace of mind as you're using the product, and protects the environment after disposal.

Best Suited for Efficient Devices

Super Heavy Duty batteries are designed to work best in energy-efficient devices that use a small flow of current intermittently, like a TV remote control, or continuously, like a clock.
