A wider range of reliable products

Three core technologies

Anti-Leak Protection

Anti-Leak Protection in all three categories

We thoroughly analyzed the mechanisms that lead to battery leakage across three main product categories and applied technical countermeasures to ensure safe and reliable performance.

Anti-Leak Protection in all three categories

When does battery leakage occur?

If batteries are left too long in an appliance, or if they are over-discharged, gas can build up inside the battery and cause it to rupture and leak.

When does battery leakage occur?

A majority of consumers have experienced battery leakage. Over 20% have had their devices damaged as a result.

Anti-Leak Protection in EVOLTA and Alkaline batteries

Our Evolta and Alkaline batteries feature unique technology to suppress the amount of gas generated due to over-discharge or excessively long storage. This improved design works to prevent leakage.

EVOLTA/Alkaline Batteries

Anti-Leak Protection in manganese batteries

Panasonic has addressed structural and material weaknesses in conventional manganese battery design to prevent leakage from occurring when in use or in storage.

Triple Tough Coating

Many consumers around the world have experienced the frustration of poor battery contact. The result is a non-functional device and a great deal of inconvenience. To resolve this issue, Panasonic came up with Triple Tough Coating.

Triple Tough Coating

How Triple Tough Coating works

Triple Tough Coating features an iron/nickel-plated alloy layer on the negative electrode terminal. Improved adhesion of the nickel plating prevents faulty connections.
