This type of rechargeable battery has existed since the end of the 70s and is based on lithium ions that are stored in molecular layers in the positive and negative terminals of the battery. Hence the name lithium-ion batteries. Compared to lead batteries, they are lighter, charge faster, and have more charge cycles.

In this table, I have compiled some different characteristics for the most common types of batteries used on board boats today. The figures are approximate as there are some variations between manufacturers. I have also created a table you can use to calculate the life cycle cost of different battery types.

In this article, I write about a few different things that affect the type of battery and how much battery capacity may be needed for various purposes on board. Here you can find information about the typical consumption of electric energy, how much electricity production is needed, and a justification for the battery choice in…

Often you need more capacity than what is in a battery and this is solved by connecting several batteries in parallel. If the subsystem needs a higher voltage than a battery has, it is solved by connecting batteries in series. In this article, you will learn how to connect the battery bank.

There are several different chargers on board that are used to charge batteries from different energy sources such as the alternator on the main engine, shore power, solar panels, wind turbines, hydro generator, or generator. It is easy to get complicated electrical installations with different chargers that must work together to charge the important and…
