  • Able to charge dead batteries

The NOCO GENIUSPRO 25 shares all the same positives as its newest version, is that to a lesser extent.

The GENIUSPRO 25 is NOCO’s previous model before the 50 was released, and in this way, almost all of the same points can be made for both products.

The only real difference between the two is the fact that the 25 has slightly worse performance and slower charging speeds compared to the 50 while still not having any display.

Don’t get us wrong, the NOCO GENIUSPRO 25 is still a solid choice when it comes to a 12/24 volt battery charger, and if you are looking for a less pricey alternative to the 50, then the 25 is the way to go.

Pros

  • Battery repair mode
  • Smooth power transfer
  • Charge fully depleted batteries

04. Ably Zyx-J30

 

 

Highlighted Features

The ABLY ZYX-J30 manages to do so many things right, and for some, it may even be the perfect battery charger.

One of the focal points of ABLY’s newest entry is its incredible-looking LCD, which not only looks smart but also displays all the information you need in one small area.

In addition, the number of safety measures that are included within this product is truly impressive, and if you have an eye for safety, you can’t go wrong.

The only real downfall to this charger is the fact that it can be somewhat difficult to use compared to most of the other options out there.

So, if you aren’t familiar with the inner workings of battery chargers, it may be best to steer clear from this one.

Pros

  • Great display
  • Safety measures
  • Automated

Cons

  • Difficult to operate

05. Yonhan Zyx-J30

 

 

Highlighted Features

  • Easy-to-use
  • LCD
  • Lots of safety measures
  • Battery repair

The YONHAN ZYX-J30 would almost be the perfect 12/24 volt battery charger were it not for one huge fault within the design.

When the ZYX-J30 is connected to a battery but lacks a power supply, all of the power from the battery gets drained to charge the charger.

For the vast majority of people, this won’t be an issue at all.

However, if you are prone to power outages wherever you live, you may find that this charger drains your batteries more than it charges them.

If you can get past this fault, then you have an amazing charger that’s easy to use, has a great LCD, possesses incredible safety measures, and many other positives.

However, this entry is not for everyone.

Pros

  • Simple to operate
  • Informative LCD
  • Preventive safety measures
  • Battery repair

Cons

  • Annoying design flaw

06. NEXPEAK 1

 

 

Highlighted Features

  • Quick charging
  • Hazard prevention methods
  • Pulse battery repair
  • LCD
  • Easy-to-use

The NEXPEAK 1 is perhaps the most user-friendly entry on this list.

For those of you who are just looking for a simple yet effective charger, this one would be a great choice.

Furthermore, it also comes with a comfortably large LCD (which makes it super easy to see what you are doing), as well as a plethora of easy-to-use control options.

However, some reports suggest the NEXPEAK 1 is not able to charge 24V batteries, even though it is advertised as doing so.

Even if this isn’t the case with every product, it’s best to keep this in mind before buying, and if you plan on charging 24V batteries, it may be better to air on the side of caution.

Pros

  • Multiple safety measures
  • Large LCD
  • Battery repair
  • Powerful

Cons

  • Cannot charge 24V batteries

07. AIMS Power CON120AC1224DC

 

 

Highlighted Features

  • High-charge capacity
  • Variable charge voltage
  • Adjustable current control
  • Quick charging

The next generation of the AIMS power series is certainly nothing to scoff at.

Moreover, it has some of the best qualities out of any of the other 12/24 battery chargers on this list.

It has a huge power capacity – you can get days or even weeks of use before worrying about a recharge.

Furthermore, it has a plethora of control options (more so than most other chargers), and it also happens to have one of the quickest charge times out of anything else available on the market right now.

The only downside to this entry is the fact that there is no display whatsoever – leaving users to feel somewhat lacking when it comes to information.

However, overall, the newest generation of the AIMS power line is a solid choice.

Pros

  • Large capacity
  • Lots of control options
  • Fast charging
  • Auto-detects DC voltage

Not only is this 12/24 volt battery charger extremely compact and durable, but it also has great safety features, is highly compatible, and even has three different modes that allow you to have more control over the charging process.

The only downside for this one is perhaps the fact that there is no LCD, but for such a small device, that is more than expected.

Pros

  • Compact design
  • Preventive safety measures
  • Usable with multiple battery types
  • Resistant

Cons

  • No display

09. Associated Equipment 600

 

 

Highlighted Features

  • High performance
  • Weather-resistant
  • Large fan
  • Long-lasting
  • Automatic timer

When it comes to pure power and performance, Associated Equipment’s latest model by far takes the bag.

Furthermore, if you are looking for a 12/24 battery charger that has an enormous power capacity, then you are in luck.

The 600 truly is an achievement to marvel at.

Although, there is one thing you need to know before we go any further; this battery charger is huge.

So huge, in fact, that it even has a set of wheels to make transportation easier.

So, if you were planning on only ever keeping a battery charger at home and have no need for it to be easily portable, then the Associated Equipment 600 may be the perfect choice for you.

Pros

  • Powerful
  • High capacity
  • Durable
  • Has wheels

Their newest model has a plethora of great features, such as the great-looking LCD, an innovative repair function, faster charging, and that goes without mentioning the fact that it can also change seamlessly between an automatic and manual mode.

Despite all of the good points, there is one big negative that you need to be aware of with the MF-20B, and that is the fact that it isn’t compatible with all the usual battery types you’d expect from a battery charger.

Pros

  • Able to operate both manually & Automatically
  • Easy to read LCD
  • Fast charging
  • Widely compatible

Cons

  • Certain battery types not compatible

The MX-C25L is a great all-arounder and scores well across the board.

Beleeb’s newest venture into the battery charger industry produced us a device that has not only a respectable level of performance but also one with a seemingly endless number of safety features.

Furthermore, this battery charger is one of the more user-friendly additions to our list, making it great for beginners.

However, similar to our last entry, the MC-C25L is a little limited when it comes to the types of battery it can be used with, and it’s something you’ll want to look into before making a purchase.

Pros

  • Informative LCD
  • Good safety features
  • Widely-compatible
  • Easy to operate

Cons

  • Not compatible with all battery types

12. ATian K3488RE

 

 

Highlighted Features

  • Widely-compatible

  • Automatic volt detection
  • Multiple safety measures

If it were not for one huge fault, the ATian K3488RE could have found itself much closer to the top of this list.

The K3488RE is known for being prone to failure, and because of this fact, it can sometimes be a bit of a risk when purchasing.

While the build quality of this one may be questionable, it is still one of the best battery chargers we have ever had the luxury of getting within our grasp, and if you are willing to ignore the rumors and try it out for yourself, you’ll be in for a great time.

The lifepo4 has all of the usual features you’d expect from a quality 12/24 battery charger.

Furthermore, the additional features it incorporates, such as the wide array of safety mechanisms and the battery repair function, are certainly welcomed additions.

However, a common issue people face with the lifepo4 is that there seems to not be enough clearance for the clamps to operate properly, and this can quickly become a nuisance even after only a few uses.

Pros

  • Lots of safety measures
  • Good LCD
  • Battery repair
  • Automatic voltage change

Cons

  • Clamps don’t have enough clearance
  • Lightweight

Factors You Need To Consider When Looking To Buy The Best 12/24 Volt Battery Charger

There are so many vital factors that you need to look out for when trying to find the perfect 12/24 volt battery charger, so much so that it may even become a little overwhelming.

Luckily, almost all of the different components can be broken down into a few different categories, making the whole process much easier and stress-free.

That’s not to say that things will be easy, and it’s still a smart idea to spend a while thinking about your decision to get the best battery charger for you.

Making sure the battery charger you choose has all the essential factors you require is of paramount importance, and if you do not pay close attention to this fact, you can easily wind up regretting your purchase.

In this section, we will be breaking each aspect of a battery charger down into a few sizeable chunks, as well as listing the most important factors you need to consider when looking to find the perfect battery charger.

01. Charging Speed

Charging speed is a crucial factor when it comes to choosing the right 12/24 volt battery charger.

If you purchase a battery charger that has a horrendous charging time, not only will you end up waiting endless hours when you may need to charge something quickly, but you may also end up outright regretting your decision.

Of course, depending on what you plan on using your charger for, charging speed may be a factor that ends up being at the top of your priorities for some items, or perhaps not even be a factor at all for others.

Although, faster charging time is always a nice thing to have, no matter what your intended use may be.

However, it may not be the best decision to put charging time at the top of your priorities if you don’t plan on using items that need to be charged quickly, and you’d be better off focusing your efforts in another area.

02. Durability

No matter what you intend to use your 12/24 volt battery charger for, durability is vital.

In reality, if a battery charger has low durability, you can expect to replace said charger within potentially weeks of purchasing it.

Furthermore, not only is having to replace a battery charger every couple of weeks going to cost you a fortune, but it is also quickly going to become a nuisance to keep track of.

Because of this, going the extra mile to ensure that the battery charger you purchase is extremely durable and isn’t going to stop working within a couple of weeks of use is essential, and it is almost a certainty that you’ll come to regret your decision if you ignore this fact.

03. Display

The display is oftentimes an aspect of the 12/24 volt battery charger that most people forget about.

While a display might not be as important as having a quick charge time or high durability, a good display can change your whole experience when using a battery charger.

A good display allows you to see and get accurate information in a wide array of different areas, such as charge percentage, hazards, connection issues, as well as a plethora of others, all of which are extremely important.

Not only does a good display just make the day-to-day use of a 12/24 volt battery charger much easier, but it also allows you to see what is going on as well as detect any issues before they arise.

The decision of how much of an emphasis to put on the display is entirely up to you.

However, be aware that there are a plethora of advantages that come with having a good display that you may not want to miss out on.

03. Ease of Use

Ease of use covers a wide range of different factors, but in short, ease of use can mean any feature/features that make using a product easier in some way.

So, applying this to 12/24 volt battery chargers, there is an almost endless number of different variables, and you need to consider what will make the most impact on you.

This can range from having a quick access port to quickly charge one or more items much faster than usual, having specific features that indicate different variables, or even having a battery charger that has other purposes apart from solely charging batteries.

There is no end-all-be-all when it comes to ease-of-use features, and in reality, you have to see for yourself which features stick out to you based on your intuition.

04. Battery Protection

Perhaps the most important feature of all; battery protection.

There is a wide range of diverse issues that can occur when using a 12/24 battery charger, and even though you are unlikely to ever experience any serious problems, it’s always better to be safe.

In reality, there is little to no chance that any harm could ever come to you while using a battery charger.

However, there is certainly a chance that your battery charger could end up overcharging a battery (which could potentially have a detrimental aspect on performance).

Luckily, most battery chargers have some sort of safety system to stop this event from happening.

Although, it is always important to pay close attention to make sure there are suitable prevention methods in place, and if you forego doing this, you may end up ruining everything you try to charge up.

The Basic FAQs of The Best 12/24 Volt Battery Charger

01. How Long Will it Take Until My Batteries Are Fully Recharged?

Unfortunately, there is no standardized answer when it comes to the question of how long it takes for a battery charger to fully charge a battery.

There are just far too many factors involved in this equation that change the outcome to give a reliable answer.

However, most 12/24 battery chargers will give you an estimate of how long it will take to charge a battery of a specific size, so you may be able to get a pretty good idea from that.

All in all, unless you pick a particularly slow battery charger, you can expect the charging time of any charger to be relatively quick, and this is due to the technology we have available to us today.

02. Can I Recharge A Fully Depleted Battery With A Battery Charger?

The answer to this can be can tricky.

On the one hand, it is possible to charge a fully depleted battery.

However, doing so is not always a sure-fire thing, and the chances that you will be able to fully recharge a depleted battery are relatively low.

You should always avoid fully depleting a battery at all costs, and unless necessary, it’s probably not worth your time trying to recharge a battery that is completely dead.

Although, there is some good news.

In all likelihood, the chances that whatever battery you may be trying to charge is completely dead are pretty small.

Furthermore, almost all batteries will have some juice in, and if this is the case, recharging will be a breeze.  

03. What Kind of Batteries Can I Charge?

The type of batteries you can charge is dependent on the specific charger you choose to go with.

However, the vast majority of 12/24 volt battery chargers will be compatible with almost any battery you can find, assuming that said battery requires either 12/24 volts.

It’s always best to check what types of battery a charger can charge, but as a rule of thumb, if you have any modern 12/24 battery charger, you will be well-equipped to deal with almost any battery you come across.

04. Is Getting A Battery Charger Worth it?

If you find yourself having to recharge batteries a lot or recharging batteries through less suitable means, then the answer to this question is a resounding yes.

In the long run, the investment you make into purchasing a 12/24 battery charger will more than pay itself off, and that goes without mentioning the fact that a battery charger just makes life easier due to the safety one gets from knowing they have a backup plan.

Of course, if you don’t find yourself needing to charge batteries often enough to warrant the purchase of a battery charger, then the answer may be a little different.

However, owning a battery charger is never a bad thing, and it may even be a good idea to get one just so you can recharge batteries in the future.

05. Are Battery Chargers Safe?

Yes. In the vast majority of cases, you will never come up against any serious hazards while using a 12/24 battery charger.

There certainly have been cases in the past where things have gone wrong, and people have been injured, but as long as you stick to a respected manufacturer, you will not have to worry.

Of course, there are also things you can do to decrease the chance of any issues occurring, and if you choose to misuse a charger, then you do so at your own risk.

06. How Long Will A Battery Charger Last?

There is no set amount of time that a 12/24 battery charger will last.

However, if you get a high-quality charger from a reputable company, you can expect to get at least a few years of use, if not a lifetime.

On the other hand, if you decide to purchase a battery charger from a company with a less than stellar reputation, you may only happen to get a few weeks.

Quality is such an important factor when it comes to battery chargers, even more so than usual, and the difference between a good-quality charger and a bad charger is huge.

07. What is The Difference Between A High-End And Low-End Battery Charger?   

When it comes to the main differences between a high-end and low-end 12/24 volt battery charger, there are huge discrepancies in quality.

As mentioned briefly within the previous question, a good battery charger can have the potential to last you a lifetime, while a bad one can last as little as a few weeks.

In addition, there is also a chance that a low-quality 12/24 volt battery charger may not have the proper defenses against certain hazards, and this could ruin some of your batteries or even render the product completely useless.

In the long run, you are always better going for a battery charger that is going to last.

Conclusion
