Mastervolt AGM 12/270 Super 8D Battery
Mastervolt 270Ah 12V sealed AGM marine battery with 1200A SAE starting current, M8/A-type terminals, and maintenance-free construction.
The Mastervolt AGM 12/270 is the high-capacity Super 8D member of the 12V AGM range, offering 270Ah C20 capacity and a 1200A SAE cold-cranking rating. It is designed for larger vessel DC banks and starting circuits that benefit from a sealed, low-maintenance battery with high current capability. Its 268mm case width is greater than a standard 8D footprint, so compare compartment clearance, battery restraint, 73kg weight, and maximum 76.5A charge current before specifying this model.
