Best Smart Battery Chargers on the Market (2022)

A dead battery is the last problem anyone wants to deal with when out on the road. That’s why it’s crucial to always have a good battery charger on hand. However, considering the virtually endless options in today’s market, it can feel overwhelming to decide which one is right for you.

The Noco Genius1 is an excellent option for anyone looking for a smart car battery charger. This charger works on both 6 and 12-volt batteries up to 30 amp-hours, and it’s great at maintaining charge levels indefinitely without overcharging.

Still, the Noco Genius1 will not work for every situation. Here are some cases in which I would not recommend it:

In this article, I’ll take you through everything you’ll need to know to choose a charger that best suits your needs, wants, and budget.

What Is a Smart Battery Charger?

A smart battery charger is a device that monitors the status of a car battery and stops charging it when full. This prevents overcharging, which is the easiest way to damage a battery. These chargers are also able to detect bad batteries.

However, in today’s market, the options are endless. And each option comes with its own set of pros and cons. For example, the Noco Genius1 is great for maintaining battery charge levels, but it will not turn over a 10L (2.6 gal) motor. If that’s your goal, you’ll need a more powerful charger like the GOOLOO 4000A Peak Car Jump Starter.

Features to Look for When Buying Smart Car Battery Chargers

It’s crucial to consider the features you’re looking for when buying a smart car battery charger. For example, you might want a charger that can work with multiple batteries at once, while others might only need a charger for their car.

Here are more factors to consider when shopping for a smart charger:

What Type of Battery It Can Charge

Not all smart chargers can work on every type of battery. You’ll need to find one that is compatible with your vehicle. For example, the Noco Genius1 can only charge six and 12-volt batteries. These include maintenance-free, SLA, and wet cells, which are all lead-acid batteries.

If you have a different type of battery, such as an AGM, you’ll need to find a smart charger that is compatible with AGM batteries, such as the Schumacher SC1281. This charger can handle 12-volt AGM, Gel Cell, and VRLA batteries.

The Amp Rating

Another factor you’ll need to consider when buying a smart car battery charger is its amp rating. This is the amount of power the charger can put out. The higher the amp rating, the faster the battery will charge.

If you have a large battery, such as the one in a 10L (2.6 gal) diesel engine, you’ll need a charger with a high amp rating. The GOOLOO 4000A smart car battery charger has a whopping 4000-amp rating, which means it can quickly charge a large battery.

How Many Batteries It Can Charge at Once

Some smart car battery chargers can only charge one battery at a time, while others can charge multiple simultaneously. If you have more than one car in your household, you’ll need a charger that can charge multiple batteries.

However, you want to avoid charging batteries in parallel. That’s because only the first battery will get a full charge, while the rest will have an incomplete charge. Your battery’s longevity may suffer as a result.

Automatic Shut-Off

One of the best features of a smart car battery charger is the automatic shut-off. This safety feature will stop the charger from overcharging your vehicle. As you can imagine, this will prolong the life of the battery and keep it from overheating.

Some chargers come with other safety features, such as short-circuit and reverse polarity protection. This means you don’t have to worry about the charger causing a fire or damaging your car.

The Price

Like anything else, the price of a smart car battery charger varies depending on its features. You can find a basic charger for around $30, while options with all the innovative features can cost over $200.

When you’re shopping for a smart car battery charger, make sure to compare the prices and features of different chargers to find the one that offers the greatest value.

Fast Charge Capability

Not all chargers are created equal. Some can charge a battery in as little as 30 minutes, while others can take several hours. This is something you’ll want to consider if you need a quick charge.

The GOOLOO 4000A Peak Car Jump Starter charger can fill a battery in as little as 30 minutes, while the Schumacher SC1281 can take up to 8 hours.

The only issue with fast chargers is that they can overheat the battery if used continuously. Therefore, if you don’t need a quick charge, you may want to consider a charger that only offers fast charging as an add-on feature.

How to Use Smart Car Battery Chargers

Smart car battery chargers are incredibly easy to use. Here’s what you’ll have to do:

  1. Plug the charger into a standard wall outlet.
  2. Connect the clamps to the battery terminal and another metal part in the car.
  3. Once the charger is connected, the LED screen will light up and show you the battery’s power level.

If the battery is too drained, a smart car battery might refuse to charge it. This is because it might think it’s a damaged battery or might not even know it’s hooked up to one. That’s why some drivers choose to keep a manual charger at their disposal since they don’t check how much charge is in the battery.

The best part about smart chargers are their built-in safety features. These chargers will not charge a battery if it is already full, and they’ll stop charging to avoid damaging the equipment. This feature will undoubtedly prolong your battery’s life.

Key Takeaways

When it comes to choosing the best smart car battery charger, there’s a wide range of excellent options to choose from. Each of these chargers comes with its own set of pros and cons, so it’s important to know how to choose the right one for your needs.

Noco Genius1 is my personal top pick as the best smart car battery charger. However, if this model doesn’t fit your preferences, you can always choose between a few other exceptional alternatives like the Ampeak 2/10/25A Smart Battery Charger/Maintainer, TowerTop, and  LEICESTERCN battery chargers.
