We offer a diverse line of batteries with a wide range of capacities depending on the performance requirements of the device.

The technical expertise we have developed for over 90 years allows us to steadily manufacture superior batteries that meet the needs of the market.

The superior technical capabilities of our batteries allow for a wide operating temperature range.

With proprietary technology, it suppresses the increase in internal resistance during long-term use, ensuring stable performance over an extended period. (Long-life type)

Backup battery reliably operates in emergency situations for in-vehicle applications such as anti-theft alarm systems and eCall (emergency call systems). It is also used as a power source for TPMS (Tire Pressure Monitoring Systems), which monitor tire pressure and alert the driver in case of abnormalities.

Batteries for Infrastructure that can maintain performance over the long term even in harsh environments are active in various fields, including main power sources for small devices and backup power supplies for emergencies. By providing the necessary power to essential locations during disasters or accidents, they support a safe and secure living environment.

In today's era of advancing IoT device utilization, real-time access to asset information is essential. Stable communication networks support a wide range of operations such as planning, measurement, tracking, location information retrieval, and monitoring. We offer a broad lineup of batteries that deliver stable performance even during long-term operation and in harsh environments.
