When shopping for a boat battery, there are several factors to take into account. Size, cranking amps and reserve capacity should all be taken into account.

When selecting a marine batteries Malta type for your needs, you have three options: starter, deep cycle or dual-purpose. A starting battery provides short bursts of energy to start the engine while the deep cycle type tolerates deep discharges for powering accessories and electronics.

Starter Battery

Marine batteries provide power to many electrical items and appliances onboard your boat, so it’s essential that you select the correct type and size of battery for your vessel’s needs.

When selecting a battery for starting your engine and other accessories, the amount of electricity you require depends on its cranking amp rating (CA or MCA). This indicates how powerful the battery will be at 32 degrees Fahrenheit when running.

Batteries come in a range of sizes, from large 8D-series flooded lead acid batteries for diesel sport fishers to relatively small 24-series batteries used on 50 horsepower skiffs.

Marine batteries come in a range of chemistries, such as flooded lead acid, gel, AGM (Absorbed Glass Mat) and lithium iron phosphate. Your decision on the type of chemistry depends on your requirements (deep cycle versus starting or dual-purpose), performance expectations and budget constraints.

Deep Cycle Battery

There are various kinds of marine batteries available on the market. Each one is designed to power a specific application. When making your decision, there are several things you should take into account.

For instance, deep cycle batteries are ideal for trolling motors and other electrical accessories that draw power slowly over long periods of time. These types of batteries feature thicker lead plates than cranking batteries, enabling them to withstand deep discharges.

They feature longer reserve capacities and cranking amps, providing extra power when it’s most needed.

When selecting a deep cycle battery for starting or house applications, it is essential to select the correct model.

At West Marine, we offer flooded lead acid, gel, AGM (Absorbed Glass Mat) and lithium iron phosphate deep cycle batteries. Each chemistry has its own advantages and drawbacks; therefore it’s essential that you select the chemistry based on your requirements and performance expectations as well as within budget.

AGM Battery

Selecting the ideal marine battery for your boat can make or break your experience. Ultimately, selecting the ideal battery depends on individual needs, how often you use your vessel, and budget.

Finding the correct marine battery requires familiarizing yourself with the different chemical types available. There are four basic chemical categories: Flooded (wet cell), Gel, Absorbed Glass Mat (AGM) and Lithium Iron Phosphate (LiFePO4).

AGM batteries feature a fiberglass mat construction and are vacuum sealed to prevent electrolyte fluid from spilling on metal parts. Furthermore, AGMs boast an extended life expectancy compared to standard lead acid batteries, making them ideal for operating in cold weather conditions.

AGM batteries offer more starting power and are simpler to charge than flooded lead acid models, making them suitable for both starting and deep cycle use. To guarantee consistent charging, AGM batteries need a smart charger with high efficiency.

Lithium Ion Battery

Your boat’s battery must meet all your power demands, both when cranking the motor and powering all accessories. Therefore, opt for one with an ampere hour (Ah) power capacity or reserve capacity (RC).

You can also assess vibration resistance, which is an excellent way to extend the lifespan of your battery. Your motors cause constant vibrations which can erode away at its internal components.

Conclusion

You have three chemical technologies to choose from: Wet cell, gel cell and AGM batteries. Each type has its advantages and drawbacks; for instance, Wet cells are cost effective but require regular upkeep like checking and refilling of the acid electrolyte. AGM and gel cells are more expensive but spill proof; finally you can upgrade to lithium batteries which offer greater power but come at a higher price tag.
