Continental 27M-EFB 12 V Group 27M 640 CCA / 160 RC Marine Start-Stop EFB Battery

Continental 27M-EFB 12 V Group 27M 640 CCA / 160 RC Marine Start-Stop EFB Battery

The Continental 27M-EFB is a robust 12-volt battery designed specifically for dual-purpose marine, RV and start-stop automotive applications requiring strong starting power and reliable deep-cycle capability. In the Group 27M size, it delivers approximately 640 CCA and a 160-minute reserve capacity, making it well-suited for boats, finish-vehicles, or entry-level start-stop cars where frequent engine restarts or accessory loads demand more than a conventional flooded battery.

Built with Enhanced Flooded Battery (EFB) technology, the 27M-EFB incorporates advanced plate and electrolyte designs to tolerate deeper discharge, higher recharge demands, and extended cycle life compared to standard batteries. Its maintenance-free, leak-proof construction ensures dependable performance even in harsh marine or automotive environments. With a 48-month warranty and heavy-duty specification, this battery offers a high-value replacement for vehicles or equipment needing stop-start or marine power solutions.
