Pressure Compensated Cells for use in Undersea Vessels

GS Yuasa has been manufacturing pressure compensated lithium ion cells since 1996 and is currently a world leader in this technology.  Our cells and batteries have been used in both unmanned and manned undersea vessels and have performed without incident to date.


Our pressure compensated cells are being used to power undersea systems such as:

  • The SHINKAI 6500 RHOV (6,500m depth)
  • OROV 7K (7,000m depth)
  • URASHIMA (3,500m depth)
  • Demonstrated undersea capability
  • Demonstrated reliability
  • High capacity for primary power application
  • Functionality can be tailored to meet customer requirements
  • Excellent cycle and calendar life
  • Acquired years of operating data
