And s ome dual purpose batteries can work for both cranking and trolling.

A deep-cycle (trolling) battery keeps it operating and runs electronics in any conditions.Ī third option (for some people):Dual Purpose Marine BatteriesĪs with many rules - there can be exceptions.

A cranking battery ensures a boat can easily start and get out on the water.

Put another, you’ll usually get the best results and smallest operating costs when you use two separate marine batteries. By the same regard, when a deep cycle battery is called upon to provide the bursts of energy necessary to start an engine, it won't always perform. trolling), it is subject to overheating and depletion of available capacity. When a cranking battery is subjected to continuous use, (e.g. They’re both intentionally engineered to do completely different things. It is very difficult to combine the performance of a cranking battery and a deep cycle battery into one battery. But that approach will cost you more money and time in the long run. It can be tempting for any boater to want to minimize accessories and additions to their vessel. Why You Can't Use the same Battery for Cranking & Trolling Deep cycle marine batteries are much less likely to overheat since their thicker plate construction can withstand high temperatures during heavy currents. Deep cycle batteries can be entirely drained and recharged many times over, where as cranking batteries can't. One key difference is the battery plate: It has fewer, thicker plates allowing the battery to provide continuous power output over long time periods. A deep cycle marine battery, or trolling battery, has several design differences. That’s where deep cycle marine batteries come in. Deep Cycle Marine battery Design Features

Instead, the boat needs continuous, reliable power for trolling-including running electronics like sonar, GPS, and radios. Once a boat's engine has started, it no longer needs the same quick and powerful bursts of energy that come from a starter battery. That's why deep cycle marine batteries are another necessity for boaters. The same elements that make a starting battery ideal for cranking an engine also make them less than ideal for continuous discharge or “cyclic” use. That is exactly why cranking batteries have many thin plates they increase surface area and make starting a marine vessel as smooth and reliable as possible. The more plate surface area inside the battery, the easier it is for that battery to provide the necessary power.

To start a motor, short and strong bursts of energy must be sent from the battery. For this reason these batteries are also known as starter batteries.

A cranking battery allows a marine vessel to start by sending power to the engine when the ignition switch is activated. If you are in need of a boat starting battery, A marine cranking battery is a great option. This starts, of course, with knowing the differences between the two most common types of marine batteries: cranking batteries and deep cycle marine batteries. Even the best battery is only as good as its application and maintenance. But, with the different types of marine batteries that are on the market, how do you know which one is right?Ĭhoosing the right marine batteries is more than a matter of going with a reliable brand that your customers can trust. The Summer season is here, and if you're a boater, you know how important it is to have the right marine battery for your boat.
