How To Keep Boat Batteries Charged


Boat batteries are a thing of beauty. In one aspect, they look really nice and robust (heavy!). In another aspect, they very particular as to the nature of their design. Often used for the unique challenges of marine life and operations, these boat batteries or aptly named marine batteries are far ahead compared to the car batteries we find on land.

That said, due to the nature of having two functions in terms of batteries (the cranking function and deep cycle function), it is of paramount importance to keep these batteries in tip-top condition and furthermore, secure their longevity or much, much later use over time. That said, here are some good reminders and tips on how to keep boat batteries charged. This applies to a general context and specifically, to short-term and long-term use.

Okay, let us first review on certain kinds of boat batteries. This is important because of the general context talked about earlier. Ultimately, we have to go back to the basics when it comes to conserving (for the short-term) and reserving (for the long-term) our batteries. So, without further ado, let us proceed to the review.

The first kind of battery (and its material) also the oldest in terms of use and application. The first kind is labeled as lead-acid or a lead-acid type. This type uses a lead plate housing a compound known as sulfuric acid. This compound (sulfuric acid) is formed as solution known as an electrolyte. This is a standard protocol or procedure battery type.

Subsequent kinds of boat batteries fall under what is labeled as gel cells and batteries that have absorbed glass mat technology (for short, AGM). One of the key distinguishing features of the lead-acid battery is that sulfuric acid based electrolyte is presented as a fluid or liquid solution. By this process, the kind of batteries that have gel cells and absorbed glass mat technology do not have these liquid forms.

Furthermore, due to their unique design compared to the standard lead-acid batteries, they do not need to worry about the liquid solution to be filled up and again in every situation that it is used. Adding to this, even more, batteries that have gel cells and absorbed glass mat technology have a better “deep cycle” rate (important for propelling motor action for marine operations) and reduced discharge rate and an increased safety measure and tolerance to low ventilated areas due to their non-liquid state design.

Of course, for all these benefits, they also cost a lot more compared to the standard lead-acid battery variety. If you are willing to learn more about this topic, then here is the resource: https://batterymanguide.com/

So, in essence, you could just simply shift to any of these batteries outside the standard lead-acid variety and get more ‘bang for your buck’ as this help conserve (again, for the short-term) and preserve (again, for the long-term). That said, not everyone will have the options that these kinds of batteries offer and in no way should be treated as the measuring stick.

That said, because of the way that the standard lead-acid batteries are designed, they can pose a dangerous situation to individuals not often familiar with the threat they contain. The sulfuric acid solution (the liquid formed substance evened out in lead plates) usually convert to gas in the mobilization process of starting and propelling the engine.

This then merits that the sulfuric acid solution is refilled and monitored to keep these batteries in use. Due to this, lead-acid toxin exposure is a real issue and should be handled properly each and every situation when one encounters these batteries. It may not be the measuring stick, but these newer set of battery material (gel cell and absorbed mat technology) have been made for a reason, after all.

All right, let us move on to charging batteries. When it comes to charging batteries, it is important to keep these batteries in check by having batteries with low discharge rates and to monitor such constantly. Also, the dangers of undercharging or overcharging is a cause of concern.

Undercharging can become an issue, especially to the standard lead-acid battery kind, mostly due to the possibility of having sulfuric acid crystallize over time when it leaks out of the lead plate protector.

Overcharging too can cause wear and tear to the battery by virtue of potentially (in all probability) destroying the material that covers it. Some chargers are termed as “smart chargers” and they use a multi-charging process that respects what people label as the “ideal charge curve”. This ensures that overcharging a battery will not become a concern, especially to people not keen on observing the amount of discharge rate that a battery has.}

Contrary to popular imagination, batteries that are charged by means of solar panel infusions or solar power generation can contribute to overcharging. Anyone who has had a chance to check out solar panel products usually finds out that solar panel products cannot store so much solar energy at a fast enough rate. This should not apply them to the situation at hand, but some data suggest that they do.

So, if you are not so keen on maintaining or observing the battery functions around your boat, it is best to keep to “smart charger” types as they often have a self-regulation function to keep you and your batteries in good health. It also pays some dividends to go out and seek some good advice from auto-part shops as they have a good amount of knowledge regarding the wear and tear of batteries (their overall lifespan) and how to squeeze out as much energy within the operation procedures, as well as tips and tricks to taking further care for your boat batteries.

But, as a general rule, folks: always keep your boat batteries charged constantly, observe the ideal charging curve and do not forget to keep batteries clean and well ventilated at all times.

Hopefully, this info and tips answer your questions on how to keep boat batteries charged for short-term and long-term use.
