What is the difference between marine batteries and automotive batteries?

Marine batteries are a type of battery specifically designed for use on ships. Their design is much more powerful than ordinary batteries and can withstand vibrations on board ships. Like other batteries, its purpose is to provide power to the electrical equipment on board and start the ship's engines.

Car batteries are car batteries used for automobiles. Its purpose is to provide engine start-up. It is a very important component in internal combustion engine vehicles because the engine is started by a battery.

Before we compare marine batteries with automotive batteries, we should know that most marine batteries are lithium-ion deep cycle batteries, while automotive batteries are traditional lead-acid batteries.

Durability
When we think of the word durability, we think of the name lithium-ion battery. Because based on new technology, it guarantees us that they are more durable. Due to the fact that marine batteries are only used to start cars compared to automotive batteries, they are not intended for longer periods of time. But marine batteries like deep cycle lithium batteries are not only used to start ships, but also provide a continuous source of electricity for other purposes on board.

The size of the battery panel for lead-acid batteries
Car batteries or starter batteries have more lead than deep cycle batteries, but lead is much thinner. There are fewer modules for deep cycle batteries, but they are heavier and thicker. Marine batteries are hybrid, somewhere in between, similar to automotive batteries, but with a slightly thicker plate.

Robustness
When we talk about marine batteries, we know that there will be vibrations on board. Marine batteries need to be stronger than car batteries. Therefore, in order to solve this problem, scientists have proposed a new type of battery, namely lithium-ion deep cycle battery. It can withstand vibrations on board and work efficiently on board. Compared to car batteries, marine batteries have thinner battery panels and may be broken during continuous movement.

Discharge capability
Due to the fact that car batteries have more thin plates, they can initially emit a large amount of current. However, due to its structure being only used to ignite the engine, it cannot be used for continuous flow. And most marine batteries have a dual nature, which means they have a continuous current to keep the engine running for a long time. The initial discharge capacity of marine batteries is relatively small, but they can provide a longer period of current.
