what type of battery is a deep cycle marine battery.
Summer has arrived, and if you are a boatman, you will know how important it is to equip your boat with suitable marine batteries. However, there are many types of marine batteries on the market, how do you know which one is correct?
Choosing the right
marine battery is not just about choosing a reliable brand that customers can trust. Even the best battery depends solely on its application and maintenance. Of course, the first thing to understand is the difference between the two most common types of marine batteries: starter batteries and 12V deep cycle marine batteries.
What is a marine starter battery?
Marine batteries can be starter batteries, dual-purpose batteries, or deep cycle batteries. They are usually a mixture of starter batteries and deep cycle batteries. The lead sponge board is thicker and heavier than the initial battery board, but not as thick as a true deep cycle battery board.
If you need marine starter batteries, marine starter batteries are a good choice. When the ignition switch is activated, the starting battery allows the ship to start by supplying power to the engine. Therefore, these batteries are also known as starter batteries. To start the motor, a brief but intense burst of energy must be emitted from the battery.
Design characteristics of crank battery
The larger the surface area of the electrode plates inside the battery, the easier it is for the battery to provide the necessary power. That's why there are many thin plates for starting batteries; They increase the surface area and make the start of the Marine Corps as smooth and reliable as possible.
The same elements that make starting batteries an ideal choice for starting engines also make them less suitable for continuous discharge or "cycling" use. That's why deep cycle marine batteries are another essential for rowers.
What is a 12V deep cycle marine battery?
Once the ship's engine is started, it no longer requires a rapid and powerful energy burst like starting a battery. On the contrary, ships require continuous and reliable electricity for towing, including operating electronic devices such as sonar, GPS, and radio.
Design Features of 12V Deep Cycle Marine Battery
This is where deep cycle marine batteries come in handy. There are several design differences between deep cycle marine batteries or towing batteries. A key difference lies in the battery plates: they have fewer and thicker plates, allowing the battery to provide sustained power output for a long time. Deep cycle batteries can be completely depleted and charged multiple times, while startup batteries cannot. The possibility of overheating in deep cycle marine batteries is much smaller because their thicker electrode structure can withstand high temperatures under high currents.
Why can't the same battery be used for starting and fishing?
Any crew member hopes to minimize the number of ship accessories and fittings. But in the long run, this method will cost you more money and time. It is very difficult to combine the performance of a startup battery and a deep cycle battery into one battery. They are all intentionally designed to do completely different things.
When the startup battery is continuously used (such as for fishing), it will overheat and exhaust its available capacity. Similarly, when a 12v deep cycle marine battery is required to provide the energy burst needed to start the engine, it is not always effective.
In other words, when you use two independent marine batteries, you usually get the best results and the lowest operating costs.
Overview of starter batteries and deep cycle marine batteries
Activate the battery to ensure that the ship can easily start and leave the water surface.
The 12V deep cycle marine battery can maintain operation and run electronic devices under any conditions.
The third option (for some people): dual-purpose
Marine Lithium Battery
Like many rules - there may be exceptions. Some dual-purpose batteries can be used for both boat start-up and towing at the same time. However, these dual-use batteries may not be the right choice for every ship. Although they do mean buying and maintaining one less battery, like many "2-in-1" options; They do not always make a ship's performance the same as two batteries.
For example, deep cycle batteries can withstand multiple discharges and charges, but starting batteries cannot. Therefore, dual-use batteries are in between the two. Many cannot withstand the total discharge capacity well (discharge capacity exceeds 50% of available capacity).
Dual purpose batteries are also more prone to overheating under harsh conditions, which is definitely not ideal for ships going out to sea. However, if used and maintained properly, these types of batteries can be well suited for short distance travel.
conclusion
The starting battery is suitable for onboard or outboard marine engines, but if you need to power the towing boat motor, please choose a 12v deep cycle marine battery. Ideally, you should have a battery for starting and a deep cycle battery for auxiliary towing motors and accessories. However, if you can only install one battery on the ship, the battery you choose depends on the required power consumption.
