In this article, we are going to talk about the marine battery sizes and how it affects your device, how you can choose the correct one and how many kinds of batteries exist. This article is going to help you to make a decision about which marine battery size fits better. 

Understanding Marine Battery Basics

Marine batteries are well designed for use in boats or marine devices or other recreational equipment used on water. They are specially used in place of tradition.

Marine batteries are special starter and deep-cycle batteries designed for use in boats and other recreational equipment used on water. They specifically use tradicional lead acid automotive and employ features that support specific requirements of the running system of engine boats. 

They are used in place of traditional lead-acid automotive batteries and employ features that support specific requirements of your boat’s engine and running systems.

TYPES OF MARINE BATTERIES

Marine batteries come in different kinds and setting up, each comes with specific marine application The following kind of batteries are Flooded lead acid, Absorbent glass mat and GEL batteries.

FLA (FLOODED LEAD-ACID) BATTERIES 

These are one of the most common marine batteries. They are considered the best value and so easy to handle and install. These batteries usually come with a free maintenance design, while others deep cycle batteries require regular maintenance.

AGM (ABSORBENT GLASS MAT) BATTERIES

AGM battery design uses some kind of material like fiberglass mat to absorb electrolyte and is added to batteries during the production process. These kinds of batteries are more expensive than flooded batteries.

GEL BATTERIES

Gel batteries are very similar to Flooded lead acid batteries, but the difference is that this one uses gelled electrolyte instead of liquid electrolyte. They are spill proof, maintenance free and some people replace this one instead with FLA batteries.

LITHIUM-ION BATTERIES

These kinds of batteries are actually the most popular in marine applications due their low density energy ratio. Anyway, these kinds of batteries are more expensive than the other types of batteries.  Also it is very important to achieve with all certifications to continue using without any problem.
