Different Types of Marine Battery-3 Basic Types & Solid Features

There are different types of marine battery to pick from. However, they all rate by energy output commonly expressed as ampere-hours. Most batteries get categorized by how many charges they are capable of withstanding during their lifetime.

Batteries with a longer lifespan will determine the price. Of course, there are many characteristics from your boat you must know before making a buy. For example; its chemical type, how many batteries you will need to efficiently power up the machine, the uses you will be putting the battery through, etc.Nonetheless, the most common three types of deep cycle battery are:

Types Of Marine Battery By Construction

Flooded Battery

These batteries are also known as wet cells. Flooded batteries have a good positioning in the market and customers can rely on them. These are a perfect fit for boats at an accessible price.

Flooded ones are the most common and accessible types of batteries available to buy in the market. They gain power from a reservoir of liquid sulfuric acid that acts as a pathway between its lead plates.
The electrolytes in this type of battery can produce hydrogen and oxygen when the battery is charging, which is why it requires boxing with enough ventilation.

Flooded batteries often require inspection, and you will need to use distilled water as a maintenance procedure. These batteries self-discharge faster than AGM quality batteries or even gel batteries.

Gel Battery

These batteries work on a gel combination from many elements that could be dangerous, like sulfuric and phosphoric acids. However, it has a design that maintains these elements inside, and avoids any spilling if it suffers any damage or has a malfunction.

The pressure inside can produce water from the gases. This process reduces any possible hazard the customer could face when the battery is functioning. Furthermore, this is a process that keeps the systems secure while it charges. Gel batteries often don’t need high voltages for recharging, like other types of battery require. When you charge the battery at a low voltage, you can keep it from overcharging, and it will have higher durability.

Regardless of its type, this is one of the most reliable sources of energy. You can count on it to power up whatever device or machine you might need.

AGM Batteries

These batteries have separators to keep the acid electrolytes between the battery’s inner compounds. It makes it a very secure and efficient battery to own. Because of its design, they have stronger resistance than flooded or gel batteries when it comes to shocks and vibrations.

This type of battery also delivers a maintenance-free feature. This feature allows the battery to have longer durability and resistance without high levels of maintenance by the customer. This is a great highlight for people who don’t have high technical knowledge about maintaining a battery.

Deep Cycle Vs Regular Battery

When you decide to buy a new battery, there will always be an important question you should ask yourself, and that is what type you should get your hands on.

It’s important that buyers understand the highlights and limitations of each type of battery to pick the right one. Buying a compatible battery will enhance your vehicle’s performance while also maintaining a longer lifespan for the battery.

Deep Cycle

On one hand, we have deep cycle batteries. These are specifically designed to offer a constant current with high intensity for a longer period of time.

It improves the engine’s starting speed by augmenting the amount of power. While doing this, the battery is capable of saving and efficiently maintaining energy.

This category works for starting as well and is able to provide a surge if the vehicle demands it. However, they often have lower cranking output. For example, kids’ electric scooter requires initial power to starts, deep cycle battery is the optimum choice for this purpose.

Once it discharges, manufacturers recommend using a lower amp hours rating to make the battery available for a longer amount of time.

Regular Cycle

In case of regular batteries, the design focuses on providing quick bursts of energy, just like many vehicles use when starting up. Fortunately, these quick energy bursts do not have a very high impact on the battery, which is then compensated by other units such as the alternator.

Once the engine starts, the alternator takes control adding the power the vehicle needs. Because of this, the battery’s durability increases.

Manufacturers are capable of combining all of these features to create a quality product and meet the regular battery’s goal. However, to achieve this efficiency, regular batteries often trade reserve energy and deep cycling capacities.


Regular batteries offer a large amount of current in a short period. Deep cycle batteries are capable of delivering a steady amount of current for a longer time
