HEP-DD165/175-V Prototype Cells
High Temperature Primary Battery
High temperature primary battery cells are designed to meet the next generation of challenging underground applications for the energy industry. HEP-DD165/175-V series cells are improved with a novel feature of multiple discharge voltage plateaus, allowing users to easily estimate battery remaining capacity based on cell voltage change. More battery product series will be available to meet applications in different temperature ranges.
Testing
