This data was provided by Mercury Marine's R&D Department. The batteries listed are ALL AGM (Advanced Glass Mat) batteries, and were required to have a rating of at least 1000 MCA, 800 CCA, 180ah, or meet the 135-RC 25 Capacity Rating. Batteries were tested to ensure that they "met" their advertised capacities also.
All of the batteries listed are heavy- and they are not cheap. However... if you want something you can depend on... a wise investment!

Although these batteries were tested for use with the Verado Engines, their superior Reserve Capacity Ratings would make them an EXCELLENT choice for Optimax or EFI engines used in a Bass Application!
