With the Bullet-shaped Bicycle Lamp and Excel Dry Battery the lighting time of bicycle lamps went from 2 to 3 hours to 30 to 40 times longer. This also lit up the spirits of cyclists.

Square-shaped battery lamps were a big hit and battery production couldn't keep up with demand. So, the Matsushita Electric Eighth Factory was set up in facilities transferred from a competitor, making mass production possible.​

National HYPER, Japan's first dry battery with a metal outer case, used a unique technology to make the change from a paper outer case. There was virtually no battery leakage and storage stability significantly improved as well.​

Battery-operated Gas Burner Lighter reached 2 million households due to its portability. Thereafter, in addition to lighting, various battery-operated products were developed for such fields as heating, power, and sound, to continue to make people's lives more convenient.

From National HYPER onward, the life of batteries became longer and longer. Hi-Top had a battery life 2 times longer than the conventional model and NEO Hi-Top's life was 1.5 times longer than Hi-Top's. Both realized the world's longest life at the time.

Batteries evolved diversely due to a worldwide demand for lightness, smallness, and powerfulness. Especially, lithium-ion secondary batteries (1994 -) made notebook PCs and smartphones lighter in weight. They are backbones of today's information-based society.

When a Japanese party conquered Mt. Everest for the first time, the whole country was proud. In the harshest environment on earth, NEO Hi-Top supported important tasks, such as weather observation and communication between members.

Motorization accelerated in the 1970s. Japan's first car battery CAREC with its ease of maintenance significantly contributed to the evolution of mobility in Japan.

The growing worldwide concern for the environment changed our battery development and led to the mercury-free dry battery. With a view toward a future where people's happiness and global environmental sustainability will harmonize, our challenge continues.

Fighting against climate change is the biggest challenge for mankind and mobility energy plays a key role. We once provided batteries for Toyota Prius and are now providing for Tesla. As energy that will change the future, the evolution of mobility energy must continue.​​​

Our energy incorporated in the return capsule of the asteroid probe Hayabusa fulfilled its role throughout its harsh and long journey. Later, our technology contributed to the success of the mission of Hayabusa 2 as well.​​​​​​

eneloop, developed by SANYO Electric through company-wide efforts, and Rechargeable EVOLTA that followed it changed the status quo of batteries being disposed of after onetime use. The number of users continues to increase even today.
