New chemistries continue to emerge as technology advances.Plan Review: Plan review and proper designtestingprocedures(DVTPs and PSTPs) should be completed early intheconstructionprocess.Ifplan review and system design testing have not been approved by delivery, marine inspectorsmayrequireplanreview to be completed through the Marine Safety Center.Material Condition: Batteries should be visually inspected for signs of deteri-oration, such as bulging cells or corrod-edelectricalconnections.Documen-tation on the completion of required maintenance should be maintained.Operational and Maintenance Pro-cedures:Crewmembersresponsible for battery operation and maintenance shouldbewell-trainedinthemanu-57 JULY 2025'
