To begin with, I propose to consider what a dual purpose marine battery is.
Traditionally, while choosing from a huge variety of different products, the best dual purpose marine battery still remains worthy on the market because people are used to its reliability and power. If we see the word “dual”, we can conclude that such batteries perform the function of both traditional deep cycle and starting batteries.

As for me, dual purpose marine batteries are incredibly convenient, because, for example on fishing boats, the electronics onboard work on the basis of a starting battery. In fact, you need to understand that they have the power to run the outboard motor and the power to power the electronics for a full day of use. That is why, by choosing those types of batteries, you immediately save energy, time, money, and at the same time get a universal device for powering all your electronics.
