 Best of the Best 

NOCO Genius G4 6V/12V 4.4A 4-Bank

Rating : 4.8/5

Why is it Our Top Pick ?

The NOCO Genius G4 ranks as our best marine battery charger overall due to its advanced features. This battery charger can charge four batteries simultaneously with four charging banks. It has the power to charge 12 volt batteries at 40 amps an hour.

The G4 also works like a mechanic’s assistant by helping you diagnose a multitude of battery complications just by hooking the leads up. Technologically speaking, this is the most futuristic charger we could find and we love the capabilities to charge pretty much any battery you can get your hands on. It can even work on micro-hybrid start-stop smart cars and CANBUS electrical systems.


You could waste your time charging a battery that is no good. But why? The G4 can tell you right away if the battery is no good. This battery charger helps you out with diagnostics by testing your problem battery for several red flags.

The G4 can alert you to:

  • Battery not holding a charge
  • Battery shorts
  • Reverse polarity
  • Battery voltage too high for set charging mode
  • Battery voltage too low to detect
  • Advanced charging

The G4 also monitors your battery voltage while charging and adjusts the current to get a perfect charge whether you are working on six volt or 12 volt batteries.

It also has an auto shut off so you can leave it hooked up well past the time charging is complete. This charger can work on all types of lead-acid batteries.

We like the low temperature battery charge feature. The G4 has an internal thermometer and can switch to a more optimum battery charge mode when in cold weather.

For really old dead batteries, this charger features a repair mode. The charger senses sulfation in old weak batteries and uses a low voltage pulse method to attempt to desulfate and restore the battery.

Fast charge

The NOCO can fully charge a standard marine battery very quickly. It works about twice as fast as you can expect from other battery chargers on the same battery.

Small, sturdy design

The G4 is very compact. It measures less than 10 inches by 10 inches and weighs only 2.7 pounds. It can stand up to the occasional car driving over it and is waterproof.

The design addresses the problem of getting to hard to reach batteries with five foot long leads. The charger also adapts to NOCO’s XConnect cable system to allow a variety of lengths of high quality cable.

The people at NOCO are so sure of the sturdiness of this charger they backed it up with a five year warranty.


The NOCO G4 more than meets the requirements of a marine battery charger. This little powerhouse charges all lead-acid batteries as well as newer lithium ion batteries. It has an advanced diagnostic system and is very easy to use.

The G4 is our number one marine battery charger because of all the advanced features. It also has a vast number of uses aside from marine batteries, which should make it all the better to have around the house.

The Best of the Best Marine Battery Charger - 2016

 Best of the Best 


Rating : 4.8/5

- Buying Guide : How to Choose  the
Best Marine Battery Charger

The marine battery charger products we reviewed for 2016 offer many different features for many different uses.

While there is sure to be a battery charger that is right for you, it is best to know all the available features to make sure you get everything available you are looking for.

Some of the things you may need to consider before buying a battery charger include:

Uses for your charger

If you are looking to charge a deep cycle battery for your trolling motor, you will probably look for the standard portable charger you can plug in and use on multiple batteries.

On the other hand, if you are interested in maintaining batteries for long periods of time you will want a charger that you can plug in and leave for months. Believe it or not, if you want to keep a charger on your battery while your boat is in storage for the winter months there is one for that too.

Choosing the right battery charger depends on which options you are looking for as well. Look for the charger that has the best combination of all available options.

Know your battery types

Lead-Acid batteries and Lithium Ion batteries

There are many different types of Lead/Acid batteries on the market; Maintenance Free, Wet Cell, AGM and Gell Cell.

Most of the different types are serviced by all the chargers we reviewed. It is important to make sure you check your potential charger to see if it can accommodate the batteries you use.

While there is one charger we reviewed that could charge Lithium Ion Batteries, you may not necessarily need to buy that particular charger.

This is true especially because Lithium Ion batteries are simply not that prevalent on today’s marine battery market.

They most likely will be one day, but if you don’t have one now you probably don’t need to get the Lithium Ion battery charger on the off chance you will get one.

Six volt through 36 volt

The battery chargers we reviewed ranged in the voltages they could operate under from as low as six volt batteries to as high as three 12 volt batteries wired to produce a 36 volt system.

You may want to look around your garage and see what you have that may need charged. A lawnmower or motorcycle could be charged with your marine battery charger if it has six volt capabilities. Your car could be charged with a 12 volt charger.

If your boat is 24 volt or even 36 volt, you probably will know already. There are on-board chargers that can be used for these systems if you need them.

On-board or portable

If you just need to charge your six volt or 12 volt battery before you take the boat out on the lake, you probably want the versatility of a portable battery charger.

The nice thing about a portable battery charger is that it will allow you to use it for any appropriate battery you have.

However, if your marine electrical system needs a dedicated charger you will most likely need an on-board model.

The on-board battery charger is installed directly into your battery compartment and you just run the power cord from the charger to a wall outlet to charge everything on your boat.

As a dedicated battery charger, you can install an on-board charger to fit any electrical system to eliminate the need to charge every battery on the boat separately.

Power banks

If you choose an on-board battery charger, you will have to decide how many batteries you want to be able to charge through your charger.

The number of banks you need for all your battery operated equipment should be considered when you configure your battery system.

If your boat has a fish finder or other auxiliary equipment, or if you think you may want to add equipment in the near future, you will probably want extra banks for your on board battery charger.

Automated charging

The best battery chargers for 2016 are all smart chargers. This means they have microprocessors that optimize charging.

They all monitor your battery’s voltage and switch between charging modes to top off your battery.

There are many features available on today’s smart chargers.

Some include extensive safety precautions including auto shut-off to avoid over charging, while others monitor reverse polarity and short circuiting as well.

If you have concerns about specific safety precautions, chances are there is a smart charger we reviewed that addresses your concern.

Advanced diagnostics

The smart chargers are not only completely automated. Some have beneficial diagnostic features that take some of the guesswork out of charging batteries.

Some of the diagnostics include sulfation testing, voltage meters and battery detection.

In all, there are a lot of advanced features on these battery chargers and we hope we have found one in the following reviews that fit your needs.

Speedy charging

Deciding which charger you need also has to do with how long you are able to charge your batteries before each use.

Some chargers have special speed charging modes that crank up your batteries’ voltage at a very fast rate.

Some chargers can completely charge a dead marine battery in just a few hours. You pay a premium for this feature, so if you don’t need to have your battery ready so quickly you can opt for a cheaper charger.

If you don’t need a speed charge option, the next thing to look at is the amps your charger can dedicate to your battery.

A five amp charger is going to charge your battery faster than a two amp charger.

If you are interested in charging at a reasonable speed four or five amps should be sufficient for a full overnight charge.

Keeping these things in mind, and adding and removing features based on your budget is key when buying a battery charger.

Make sure you don’t overspend on features you can do without.
