Optima Blue Top Marine Battery - 8052-188 12V 75Ah - BTDCM5.5, 2 Years Warranty

Product Number: BTDCM5.5

Optima's Spiral Cell AGM construction binds the electrolyte within tightly wound glass mat separators, eliminating free acid and enabling the cell stack to resist vibration, shock, and the sustained discharge cycles characteristic of marine use. The result is a battery rated at 75Ah (C20) with 975 Cold Cranking Amps, delivering both reliable engine-starting authority and the deep-cycle reserve capacity needed to power auxiliary loads over extended periods.
