Deep Cycle Marine Battery for Trolling Motor Introduction and Size

A deep cycle battery can also be referred to lead acid battery. The lead acid battery has a history, and it was the first rechargeable battery ever invented. It was first invented in 1859 by a French physicist named Gaston Plante. However, there are many modern types of rechargeable batteries which has a greater energy density as compared to lead acid batteries. 

Now you should remember that a deep-cycle battery provides power for a long period. You also have to be careful about the size of the battery you need for a trolling motor.
