We have established a service for inspecting and checking aircraft-use Ni-Cd batteries, our main customers being airlines with flights using Yao Airport in Osaka.
Moreover, we develop, manufacture and sell industrial-use batteries and related equipment.
We are also making a major effort with regard to battery recycling through tie-ups with both Japanese and foreign companies in view of globalization and based on environmental considerations.
Our aircraft-use battery inspection/testing service is utilized by a variety of carriers including operators of commercial flight helicopters, police helicopters, press reporter-use helicopters, small passenger airplanes, fixed-wing aircraft, etc.
By making passenger safety our top priority, we are continuously making proposals for service and system improvements that can cut costs for our customers, such as reporting on the condition of aircraft electrical systems based on battery inspection results, methods of reducing waste, etc.
As a supporting member of the Japan Aeronautical Engineers’ Association (AJEA), we are steadily increasing our professional knowledge and information with the aim of further pursuing benefits for our customers.
