Thank you for selecting our products. We launched our first designed charge-discharge test System in 1993, however, we have discontinued the production and sales of this old design system more than 10 years ago. We have continued to provide support to avoid trouble to the customers who purchased this system, however the repair limit of equipment is 10 years from the end of production and it has become difficult to secure the maintenance parts. We regret to announce that we are setting a certain period for the end of maintenance work on the equipment models stated below. Your understanding will be greatly appreciated.
