Primary Batteries

What are Primary Batteries?

Powering happy lifestyles

Batteries to meet your needs

Our primary battery range includes the popular EVOLTA line, our alkaline and manganese dry-cell lineups, as well as a comprehensive selection of batteries for specialist applications. Our innovative designs promise higher performance and longer life, along with enhanced safety and reliability features to protect you and those you care about.

Key features of EVOLTA/Alkaline

Long-lasting, safe, and reliable

Longer life over a wider current range

Panasonic batteries deliver long-lasting power in all kinds of appliances, from toys and remote controllers to digital cameras and torches.

Lasts longer in high-current applications

Panasonic alkaline batteries drive power-hungry devices longer.

Anti-Leak Protection technology vs. competitor products

We protect the people, equipment, and moments that are important to you using the industry’s most advanced leak protection technology. Improved materials and design prevent leakage due to over-discharge, excessive storage, or external damage.

Outer short-circuit protection

Panasonic’s outer short-circuit protection prevents batteries from bursting or malfunctioning due to accidental misuse (such as reverse connection).

Key features of Manganese

Longer life, greater reliability, and better safety

Superior endurance in low-current applications

Panasonic manganese batteries last longer in low-current appliances such as remote controls, portable radios, and torches.

Endurance Comparison

* Results based on Panasonic in-house testing with Company B set to an index of 100 averaged across all discharge modes according to IEC standards.

Improved leakage resistance

We protect the people, equipment, and moments that are important to you with the industry’s most advanced leak protection technology. An improved design prevents leakage due to over-discharge or excessive storage.

A more reliable design

Some batteries can malfunction or burst if loaded incorrectly, such as in a reversed connection. Where competition products fail, Panasonic manganese batteries won’t burst when loaded in the wrong order.

Greater consistency of quality

Our superior production control methods ensure more consistent quality across our entire battery family, reducing variations in stated capacity.

Comparison of Capacity Variation

Longer shelf life

You can depend on Panasonic manganese batteries to work even after long periods in storage. High-quality materials prevent degradation and ensure long-life stability before use.

Safe, eco-friendly design

Panasonic batteries do not contain mercury, protecting you and the environment during use and after disposal.

* Panasonic first developed and marketed mercury-free manganese batteries in 1991.

High performance in harsh climates

Most batteries suffer a sharp drop in performance when used in extreme temperatures. Our batteries are designed to operate consistently in harsh climates in most regions of the world.

Choosing the right battery

Differences in battery structures and capacities

Alkaline

For devices that use a high, continuous current
Alkaline dry batteries are able to produce a higher current than manganese dry batteries. This is because the electrolyte consists of potassium hydroxide, which is an alkaline-aqueous solution that enables a higher flow of current.

Alkaline

Manganese

For devices with a low current load, such as remote controllers
Dry batteries basically consist of three materials: metal, metal oxide, and electrolyte. Manganese dry batteries use manganese dioxide for the positive electrode, zinc chloride (or ammonium chloride) for the electrolyte, and zinc for the negative electrode.

Manganese
