Batteries require a lot of care if they are going to maintain their performance over a number of years. Getting the right battery charger is then is crucial in terms of making sure that your battery is getting the right amount of power it needs.
There are multiple different types of batteries which all have their different uses and which all require their own specific charging requirements, which is why it’s important to buy the best boat battery charger so it can provide the correct charge all the time.
Here at Globo Surf we have looked at the boat battery charger reviews to make sure that we have found the top rated marine battery charger which will be the perfect fit you’re your boat. Here we explore the key features and answer the important questions to give you the information you need to choose the best marine battery charger.
How To Choose The Best Marine Battery Charger – Buying Guide
You want to ensure that the marine battery charger can provide the right about of voltage for your battery. All batteries are different in what they require and one of their requirements can be a different voltage. Marine batteries usually run off a 12V system, however, this might not always be the case and you may want to charge other items.
You want to look for a battery that is capable of various charging powers and has the ability to charge at both 6V and 12V. There are batteries where you can switch between the two voltages and there are also chargers which will automatically switch between the two options and don’t require any manual switching. It’s important to check your battery to ensure that the charger you are getting will be a suitable fit.
There are many different types of batteries out there and they all have different charging requirements so it’s important to know which type you have. There are flooded lead-acid batteries, AGM, gel and lithium-ion options as well. On each different battery charger it will state which type of batteries it will support and which it doesn’t.
Most of these marine battery chargers we have reviewed here support a number of different battery types but you shouldn’t presume that your type is going to be covered. The best battery chargers will have microprocessors which will be able to read your battery type and adapt its amperage and voltage to meet its demands.
How durable your battery charger needs to be can largely depend on where and when you are going to be using it. If you’re taking it on the boat with you then you need to have a higher level of durability and being able to withstand shocks and having waterproof protection are great extra features.
Other users though will be wanting their battery chargers to be in a much more sedate environment where they will be used to recharge your battery when it’s not being used or trickle charge it during the off season. If you’re going to be using the battery charger for the latter then there is little need for it to be able to withstand the marine environment but if it will be on your boat then you’ll be looking for some key durability features.
As with any electrical item it’s important that there are built-in safety features in case the worst was to happen. One of the most obvious is the protection against reverse polarity which all battery chargers need to have in order to protect their users.
Other key safety features include having the right amount of fuses as well as protection from too much current, voltage and temperature. It’s important to have these features especially considering that your battery charger will most likely be left alone for a long period of time.
The charging time of your battery can depend on a large number of different factors with the most important one being the size of the battery. Also the type of the battery can play a huge role as each different type will accept a different type of amperage so having a defined time for your battery charger depends on a number of different circumstances.
One of the obvious considerations to make though is the more powerful your battery charger, the more quickly it will be able to charge your battery. If you are using your battery charger for when your boat is stored away though then this is much less of an issue as you won’t be worrying about the amount of time that it is taking.
If you have multiple batteries then you will want a battery charger that has numerous banks which means it is able to charge a number of batteries at the same time. This can be especially useful with those who have both a deep cycle and a starter battery and those who have a larger vessel with a number of different batteries.
One important consideration is whether you should give yourself the option to add an extra battery in the future. If you’re perfectly set with to batteries then getting a two-bank charger would be perfect but if you think that you might want to add some extra power in the future then giving yourself the option of an extra bank might be wise.
Recovery time is determined by your batteries ability to recover its charge after it has been fully drained. Generally the higher the amperage that your charger can give then the quicker it will be able to recover your battery. The importance of this depends on how often you use your battery and how much you use it.
The best chargers will fully recover your battery in just a few hours whereas others can take a lot longer. If you’re going to be using your boat for multiple days in a row then having a battery charger with a quick charging ability will be a lot more important than if you use your boat a lot less often.
On-Board Vs Portable Boat Battery Chargers
Whether you need an on-board or a portable charger largely comes down to what type of boat that you have. If you have a smaller vessel then having a portable model will be ideal as you wouldn’t need the same level of power and this would be a lot more convenient.
If you have a larger boat though which perhaps has more than one battery then getting an on-board charger would be perfect as this would be able to charge a number of different batteries time and time again. This would allow you to have a constant power source so that you never run out of charge.
There are a few key features which can affect the size of your battery charger but generally the larger they are then the more power they are going to be able to supply, and the more features they will have such as a larger range of banks.
You want to select a size that is going to be compatible with your boat so you need to check where you are going to store it and how it is going to be used. If you have a portable battery charger then this is obviously going to be much less of an issue as long as it’s light enough to be moved from one place to another.
If you’re going to be using an on-board battery charger then you want to make sure that you have access to a shore power unit when you are docked up if you are going to be leaving it on the water overnight.
If you’re the type to make use of your boat for a day and trailer it back to your home then this obviously isn’t a requirement. This is also where portable chargers can have their advantage as they can be powered up in your home.
Q: What Size Charger Do I Need for My Deep Cycle Battery?
A: The answer to this question can depend on many different aspects so there isn’t one obvious answer. The size and type of your battery are two of the biggest factors in determining how quickly it will be charged but as a general rule of thumb you know that the more current that you put into your battery then the quicker it will be able to charge.
You do though want to match your charger to your battery, so there is little point getting a heavy-duty charger if you only have a smaller battery and equally you don’t want a small charger if you have a powerful battery. The total amperage that your battery can accept also depends on the type of battery that it is.
A flooded battery is generally the least efficient type and will only accept a charge rate of up to 25 percent of its capacity. A gel battery will be a little bit better and accept a charge rate of 30 percent and the most efficient battery is an AGM battery which will be able to accept the highest amperage of the three and can take 40 percent of its capacity.
If you’re looking for a quick charge then you will be looking for a charger that has more amps but if you get a great charger and have a flooded battery then this won’t be able to charge as quickly as if you put the same charger on an AGM battery.
Q: How Many Banks Should I Have On My Charger?
A: In simple terms the number of banks refers to the number of batteries you can charge at the same time. If you have a smaller boat and only have one battery then you don’t have to worry about how many banks that your charger has as you will only need the one so any spare banks would simply be a waste.
The general rule is that you want to match the number of banks that you have with the number of batteries that you have, whether that is one, two, three or four. If you have grander plans for your boat though then you might have a requirement for more electrical items in the future. If you think you might expand your electronics then getting one more bank than you need at the moment will mean that you can be more prepared for the future.
Q: What Should I Do If My Battery Charger Overheats?
A: The best way to stop your charger from overheating is to buy a quality charger in the first place. The best chargers on the market will have in-built safety systems that will prevent them from overheating and will have temperature controls that will match them to their climate.
A lot of these marine battery chargers have microprocessors installed which will be able to read what your battery needs and also read them when things are starting to go wrong. These battery chargers will also know when a battery is fully charged so it can switch from a fully charging mode to a trickle charge mode.
If your battery charger is overheating then it’s an indication that something is wrong and it’s probably time that you upgraded to a smarter model. This will give you the peace of mind that you’re looking for so you can leave your charger to do its thing knowing that there won’t be any problems while it charges your battery.

Once you have your batteries fully charged then then you are able to charge to items that you need to use weather that is for fun such as listening to your favorite music, whether you’re hunting for fish and using your marine GPS or whether you’ve taken on too much water and need to use your bilge pump.
A battery can be vital to your boating experience so therefore it is vital to get the best battery charger that you can. In order to pick the right one for your need to assess how many batteries that you have and what size that they are. Once you have done that then you are able to figure out how many banks you need and how many amps that you want to run through them.
If you want an on-board charger then this will likely be able to deliver a higher level of performance but you have to make sure that it is durable and that you have access to an onshore power source. If any of those things are going to be an issue then having a more portable charger will be able to give you the performance you need.
Once you have taken everything into consideration when you are able to head out onto the water happy and confident that your batteries will be fully charged and that you’ll be able to easily charge them again once you are off your boat. A battery charger isn’t something that you can skip over, if you have a cheap one without the key features then you could be left with batteries that aren’t fully charged and eventually boat devices that have no power to run from
