What Exactly Is A Marine Battery?

If you have a vehicle, you know that you have a battery under the hood that is used to get your car started. It actually provides the electricity that is necessary for the spark plugs in order to ignite the engine. Once the motor is running, the battery is no longer needed, and can be recharged once the alternator start spinning. The same is true for batteries that are used in boats. This type of battery is called a lead acid battery, a type of battery that is rechargeable and was invented back in the 1800s. They are very inexpensive, and have an energy to weight ratio that is extremely low, which is why we continue to use them in both cars and boats around the world. The ones that are installed in boats are a little different, and are often referred to as a marine battery. Let's look at how these are made, and what they actually do for boats that are operated today.

An Overview Of A Marine Battery

A Marine battery is a deep cycle battery, one that is specifically designed to be regularly discharged, expending most of the latent electrical energy. This is very different from automotive batteries which are designed to deliver a burst of electricity with the purpose of cranking the engine, whereas a Marine battery does not discharge electricity in that manner. Whether you are using a file of regulated or flooded lead acid battery, both of these will help start any boat. They are designed with thicker every plates, and therefore the discharge cycles will be much different, often used in trolling motors in recreational fishing boats today.

Which One Is Better?

If you have a flooded battery, one that contains electrolyte fluid which will completely submerge the plates, these will work but require regular maintenance to ensure that the plates are fully submerged. Most of the Marine batteries that are used today are made from recycled material, and as a result of this, they are much more cost effective than ever before. Valve regulated batteries actually come into different forms. You can get those with gel or absorbed glass mat construction. Both of these work very well, with the primary difference being the cost, and also how much more maintenance you will have to put into the batteries so that they will last for an extended time.

People that have fishing boats, or any type of recreational boat, will have one of these batteries on board. They are designed to last for a much longer period of time than a lead acid battery for vehicles that drive on the road, but they can be more expensive due to their size and the different materials that are used to construct them. By searching the web, you should be able to find great discounts on these batteries which can cost as much as $300 or more. Take advantage of the savings that you can get from major retailers, or simply drive to the location to pick one up after ordering online.
