Everyday Energy Made Simple

High Performance in Almost Any Application

Trust Panasonic to power your day and get the most from every moment. Alkaline batteries deliver four benefits: better performance, long endurance, excellent value, and class-leading safety. With High Energy Formula optimizing the power reaction, Anti-Leak Seal protecting your devices, and Special Tough Coating enhancing reliability, Panasonic Alkaline provides effortless energy with greater peace of mind.

Look Inside

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 chance of leakage when batteries are in use or in storage. Exclusive Seal Structure employs a thin gasket with tough material that’s locked tight into the battery can wall, capped with a metal seal, and secured with adhesive. Gas-Suppressing Formula, meanwhile, uses proprietary materials that suppress gas generation, reducing pressure buildup and chance of leaks.

Exclusive Seal Structure

Precision-locked seal cap with special adhesive

Tough gasket resists deterioration for a tight fit

Gas-Suppressing Formula

Regular zinc generates gas bubbles, increasing internal pressure

Refined zinc limits gas pressure buildup and chance of leakage

Store Batteries Safely for Up to 10 Years*

You can store Panasonic Alkaline 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 powerful Panasonic Alkaline performance whenever you need it.

* Storage period varies by country/region. With batteries in an unused state and properly stored.
  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.
