How Does An Onboard Marine Battery Charger Work?


By this point, we all know that batteries of all kinds eventually need chargers of all kinds, too. Yes, it is a pretty cruel world if we were to make some joke about it. But, ultimately, it is what it is. We realize eventually that the batteries charge up our vehicles or devices, including boats and that they need to be charged too.

Fortunately, especially for people not so much familiar with the current trends and ins and outs of marine battery management and certain marine battery chargers, most developers and manufacturers are interested in making these features of their products easy to use and wonderful to have.

Some companies even created battery chargers that are specifically emphasized to work onboard the boat—right where you need them the most. But how does an onboard marine battery charger work? Well, that is what this article is for. Check it out below.

The Convenience Of Onboard and On-line


Well, not exactly online. But, the concept is pretty much the same. You see, many marine battery chargers have been done through manual installation. It is pretty much a standard procedure that many people have adopted ever since batteries were needed in order to activate marine operations or relaxing boat rides.

Now, in the age of the internet, on-board (or online, depending on your word use) is the thing. The fact of the matter is that it is convenient and accessible to people nowadays who want to invest their energy in a myriad of things.

Okay, but how does an onboard marine charger stand out compared to just manually installations or visits to a repair shop?

For one thing, they are kind of like batteries themselves. A good number of them is bulky (especially in the earlier versions of prototypes of the products). But, nowadays the products have been really streamlined and compact in order for ease of use to be a secured provision.

But, essentially, the function is the same regardless of bulky or compact: it is installed right there along your marine batteries to help you charge them as you go through sea trip or engage in deeper marine operations.

What is even most convenient about them (and perhaps, more critical) is that many of these onboard marine battery chargers are designed and modified to understand the advanced need of people and with their behaviors of charging any device: monitoring and pace and overall energy in and out usage.

Complicated as it is (except for battery enthusiasts, geeks, and nerds), the relationship of batteries and their chargers is essentially known as ‘the charging curve’. Yes, apparently this is a studied observation that needs to be respected to help you get the most out of your battery use and charging use, as well.

Onboard marine battery chargers nowadays usually rely on these microprocessor chips that monitor, pace and overall energy use. Now, different companies have more or less similar intentions and designs when it comes to these functions of the microprocessor chips.

Some companies really put an excellent portfolio with regards to the charging curve that their products are often termed as “smart tech” or “chargers that are smart”, relating to the fact that it can help manage overall charging but also is quite user-friendly and safe to use.

With regards to the “charging curve”, these are the known changes that you can observe or look out for: the bulk phase, the absorption phase and the float phase (you can guess where this comes to play).

The bulk phase is where we can see a great return in the products, initially. This all relates to how much “amp” (ampere) or “burst” they give out in order to give a great amount of recharging energy to the battery.

We take note here that most customers are very interested in these areas of the charging phase. Some even go out to seek high amped products for this very reason.

Researchers and manufacturers have provided a consensus that this constitutes about 80% of the charging process. From this point or perspective, you can understand why manufacturers and customers alike insist on the importance of high amp giving marine battery chargers.

It essentially is a greater return in investment from the get-go. You can take this phase to be one where careful monitoring is observed the most.

The absorption phase is usually taken as the 20% of the process in the recharge. This is where the charger and battery are evened out or topped off in order to have constant (and longer lasting ‘pace of energy).

Though not as focused compared to the first phase, this may be considered the ‘cooling’ part of the recharging cycle because of the dangers of overcharging. The risk of overcharging is there when this phase is not observed.

If the batteries are not topped off or evened out with the amp that the battery charging is giving, eventually, it will be a surge of energy that is non-stop. This is to say, it is quite important to provide a cap (or cooling aspect) at this point or recharging. Some companies actually focus on it inspired by ideas like temperature sensitivity or automatic on/off features.

The float stage is not actually referring to the water but the way that the energy is described. At this point, it is processed by which energy recharged is held at a constant (the constant being built from the absorption phase).

It can be assumed that most (if not all) companies focus on this area as a great feature because when the battery is now fully charged, the microprocessor can use this mode (float) to leave the battery charged on constant maintenance in an indefinite period of time.

Obvious Observations: Expensive

Yes, onboard marine battery chargers are quite expensive. You certainly do not need to use them. But, as argued above, these battery chargers can save you a lot of trouble in the long term. So, it is a question of sustainability. Remember, when asking, “how does an onboard battery charger work”, it helps to keep a reference to the charging curve.

Also, this can give you a good reference when asking sellers of these products to make sure your investment is on point. It certainly does not hurt to ask further for quality assurance. Hopefully, this article has been helpful in reminding and informing in that aspect.
