Marine battery chargers act like a saving jacket for your juiced up boats. These saviors can charge the battery and save you from challenging situations.
Selecting a suitable charger can save your day. All you need is to study all the elements before making a purchase carefully.
A buying guide presents all the necessary information in an organized way under one roof. You can easily analyze the performance and usability of the different products by going through these pointers.
So without any further ado, let us dive into this detailed guide.
If you want to maintain your marine battery efficiently, you must consider a marine battery charger. You do not need to spend a lot of money to get a good quality marine charger.
There is a large variety of products available on the market. But you must select the best marine battery charger that will be one of the most crucial parts of the boat.
Without using the right charger, the marine battery can get damaged severely. Also, it would be best if you kept the battery charged when not in use.
Having a marine battery charger will help you keep the battery in a sustainable condition and improve its performance.
For quick charging, you will need a robust and high current charger. Otherwise, you can choose a charger with a low current rate for storing the battery.
You must choose the right type of chargers that can recharge the marine battery without any damages. Typically, two charger types are there, including the manual chargers and automatic chargers.
It is effortless to understand that you can set the chargers manually. Put simply; you can turn on/off the chargers by your hands.
Also, the current and voltage can be adjusted as per your requirements. You just need to switch them off manually for a complete shutdown.
On the other hand, automatic chargers can sense both the voltage and inner current without your help. When the marine battery is fully charged, the chargers will switch off automatically.
Gel batteries have a long lifespan because they are resistant to shock and vibration. Also, they can withstand low temperatures effectively.
Liquid electrolytes are used to fill the batteries, and they are sealed. Due to recombinant technology, they do not need any water.
Gel batteries do not get affected by over-discharge, so you can store them for an extended time without recharging. They are free from plate sulfation, which is suitable for their life cycle, and this is why boaters prefer to use gel batteries.
However, gel batteries are a little bit expensive than others, and they require high voltages for recharging
Wet Cell batteries are the traditional type of battery that contains a mixture of distilled water and sulfuric acid.
A good quality wet cell battery is appropriate for 1,000 discharge/recharge cycles.
Having wet cell batteries means you do not need to worry about the weight and damage caused by overcharging.
But one major downside of these wet cell batteries is that they require high maintenance. You must examine the cells regularly and make sure that the compartments of the battery are well-ventilated.
Also, there is a chance of acid spilling, and they are not resistant to high vibration. So, it will be better not to choose them for your boats.
In AGM batteries, glass matting is packed between the plates of the battery. This saturated acid electrolyte helps oxygen to get mixed with hydrogen and, thus, reduces the need for water refilling.
They are sealed tightly, so there is no possibility of acid spilling. You need to clean the exterior frequently.
AGM batteries are easy to install, as well. They have high resistance to shock and high vibration. Moreover, they have a low rate of self-discharging.
However, AGM batteries are expensive, and you cannot replace them when damaged.
The first thing you should check while buying a marine battery charger is the size.
Both weight and dimensions of the marine battery chargers should be considered because you will not want to carry extra weight on your boat.
If you choose an onboard charger, look for the right fit so that you can stow it properly.
Also, you should check the size of a portable marine battery charger before buying it.
Checking the battery size, precisely the battery capacity, will be the right decision. You will need a powerful charger for recharging a large battery quickly.
The larger batteries with more capacity require more time to be charged completely.
Therefore, you should decide the size of the charger according to the marine battery size.
There is hardly any doubt that you must prioritize the battery voltage when you are about to buy a marine battery charger.
Most of the modern batteries come up with 12-volt units, but you should ensure whether it is appropriate for your system or not.

A multiple bank charger is handy to charge multiple marine batteries at the same time. So, when searching for marine battery chargers, you should pick up the multiple battery banks for quick recharging.
The number of batteries you can charge with the charger directly depends on the banks the system has. For example, two batteries can be charged with the 2-bank charger while you need a 3-bank charger for three batteries.
If you want to charge a deep cycle battery and a starter battery simultaneously, you can go for a multi-bank charger. Also, you can charge more than one battery on board to power several other devices.
However, it will be an imperative choice to focus on multiple battery banks instead of getting multiple battery chargers to add an extra battery conveniently.
You must calculate how much time the battery takes to get fully charged before selecting a marine battery charger.
You should remember that the charging time is related to factors like the size and type of the battery.
Every charger has its capacity for taking amperage. So, different circumstances determine how much time the charger will take to recharge the battery.
It is no brainer that having a powerful charger will always help complete the charging process faster.
Without looking for the recovery time, it will be challenging to make a good purchase of the marine battery chargers.
Recovery time refers to the amount of time the charger takes to recharge the battery when it is completely drained.
You will always be wanting your battery to recover the charge as quickly as possible.
The charging speed of a marine battery charger is determined by amp hours. With a higher amperage, you can have a better recovery time. However, it is related to the power distribution system as well.
If you have a 30amp 2-bank charger, you should remember that each bank will get a maximum of 15amp, so it will not work as fast as you think.
If you plan to be on your boat for an extended period, it will be wise to invest in a charger capable of quick charging.
For the onboard battery charger, it will be crucial to get an accessible power unit when you leave your boat on the water. Therefore, you must look for the power source if you have a plan for docking at night.
People who use their boat only in the daytime can pass over this factor. It is the reason why many people are likely to have portable marine battery chargers.
You are allowed to take the portable charger to your home to power it up at your convenience.
