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.

Exclusive Seal Structure
A: Precision-locked seal cap with special adhesive
B: Tough gasket resists deterioration for a tight fit

BEFORE
Zinc generates gas bubbles, increasing pressure and chance of leaks

AFTER
‍Newly refined zinc limits gas pressure buildup and chance of leakage

You can safely store Platinum Power batteries for up to 10 years^* when unused and stored properly. Unique high-quality chemistries, including added titanium, prevent degradation while Anti-Leak Seal prevents leakage to ensure long-life stability. These enhanced features deliver powerful Platinum Power battery performance whenever you need it.

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