5. Schumacher SEM-1562A-CA 6V or 12V at 1.5A Speed Charge Battery Maintainer

If you are traditional with the brands you trust, then you should know about Schumacher that has been producing battery chargers since the late 1940s.

The Schumacher SEM-1562A-CA is an inexpensive alternative if you’re on a budget and if you will be using it to batteries that are seldom used.

​What makes it capable is its versatility and can be used for 6V or 12V batteries with virtually no limitations. The simple instruction is just to connect and forget.

You don’t need to be concerned about overcharging because the microprocessors will prevent it from happening.

If you use this battery charger to charge a large battery that wasn’t fully charged, the battery may lose some of its capacity. The large battery will then be unable to hold a charge and would then be rendered useless.

So for the sake of preserving the state of the large batteries, better use SEM-1562A as just a battery maintainer. It works well with small batteries, though.

The battery type is detected through the automatic voltage detection. The input charge will be automatically configured, and the multi-phase charging process then commences.

It has an advanced charging technology because the charger is designed to analyze data and configure the input such as the current and voltage. The charger can make adjustments on the fly. After the battery charges at 100%, the charger automatically shifts to Float mode and will function as a battery maintainer.

But when the ambient temperature changes or the battery gets hot, the SEM-1562A will take care of the problem by adjusting the charging rate abruptly after analyzing.

This battery charger can charge deeply discharged batteries as long as there’s remaining charge inside starting at 0.1V. This is done through the Desulfation mode which takes from 8 to 10 hours. When it fails, the yellow LED light starts to blink.

Though the cable wires are short in length, they come in eyelet and clamp versions. They feature a quick disconnect harness for easy removal and have reverse polarity protection when the clamps or O-rings are connected to the wrong terminals.

The use of extension cords isn’t recommended unless absolutely necessary. Upon purchase, this one has a warranty of 2 years.​

Pros

  • Maintains small and large batteries
  • Auto voltage detection
  • Analyzes data to automatically deliver current charge
  • Two years warranty
  • Affordable

Cons

  • Not recommended for charging large batteries
  • Short cable length

6. NOCO Genius G3500 - Best Smart Battery Charger

Maintaining the maximum performance of a battery is important.

You are already aware that even if the battery is discharged or not even used, its power is continually reduced along with its battery life.

With NOCO Genius G3500, charging and maintaining the battery will go hand in hand to rejuvenate even the drained batteries.

G3500’s exterior is well-designed as two of its focal points are its portability and versatility.

Just like other NOCO chargers, G3500 works well with several battery types. It’s just not a car battery charger as it correspondingly provides services on other vehicles like motorcycles, motorboats, tractors, etc.

Just like the previous G750, there are two options either 6V or 12V, that you can change at will through a switch. Be aware that the unit can memorize the last selected mode upon next usage, so you might want to double check what battery you will be charging.

The charger is quite capable of auto adjust depending on the current needs. This battery charger/maintainer has a built-in thermal monitor in which the sensors will automatically adjust the charge depending on the ambient temperature.

The charging process is two times faster compared to others due to its cutting-edge technology which delivers superior performance.

To know the current battery percentage, there are four circles from 25% to 100% which will flash green LED. At full charge, overcharging is prevented via switching to the maintenance phase.

One thing to know about G3500 is it also doubles as a battery maintainer. You need not worry about unplugging it in fear of toasting the battery because there are smart microprocessors that will constantly observe on the battery state.

When it’s full, there’s no draw of current. So when the battery life is depleted, charging resumes until it enters maintenance phase again. G3500 is an effective energy saver.

One of G3500’s features is its ability to bring an almost dead battery back to life. With pulse charging that uses high voltage, the low-voltage, sulfation, and lost capacity batteries are rejuvenated.​

This repair feature, however, is only applicable to 12V batteries and not the 6V ones. Fully drained batteries with no detected voltage or remaining minimum charge won’t be able to charge. You may need a little help from other battery chargers to solve this problem: which is to collect some charge. Plugging G3500 after that will work fine.

Just like other NOCO chargers, all safety features like reverse polarity protection, and spark-proof cables remain intact.

Cable connectors that come upon purchase have alligator clips and O-rings. G3500 has mounting holes and a rubber base to avoid slipping and scratches from hard surfaces.

It comes with a five-year warranty.

Pros

  • Maintains battery indefinitely
  • Suited for different battery types
  • Charges 2x faster
  • Smart charging technology preventing it from overcharging

7. NOCO Genius GENM1 - Best Battery Charger For Car

The final NOCO product able to make it into our list is the NOCO Genius GENM1 which may be the most expensive among the lot. But its safety features are something to be praised.

You can say that safety is this product’s main priority to work on most types of batteries that run on 20-120Ah virtually on any type of vehicle.

NOCO Genius GENM1 boasts a rugged appearance. With its IP68 classification, it’s said to be 100% waterproof and can work even in extreme weather conditions.

Not only that, but this charger is also shock and vibration resistant. Meeting the USCG-33 CFR 183.410 requirements, NOCO Genius GENM1 is never at risk of igniting because of the temperature-controlled circuitry inside.​

As an on-board charger, you might find this one quite heavy and big. It’s actually meant to be placed in one area, unlike most portable chargers. With its dimensions 6.6x5x3.8 inches and a weight of 3.3 lb, you can consider this one to be heavy duty. You might find the cable to be quite short. It only measures 6 feet.

​One other thing to know is the cable wire. There’s only one version – the O-ring or eyelet terminal connector available upon purchasing. It limits the way to connect the charger to the battery

GEN Mini 1 uses Rapid Charge Technology which is like other NOCO chargers, it’s 2x faster than other conventional battery chargers. Not only twice as fast, but there's also minimal energy consumption to attain that.

One other thing that is common to NOCO chargers is their ability to bring the deeply discharged and poor-performing batteries back to life. It can recover the sulfated batteries by pulse charging (transferring high voltage).

Charging process of this battery charger takes eight steps. If the battery charge has stopped on Bulk Charge mode for a long period of time, the charger will automatically shut down.

Upon auto switching to maintenance phase at full charge, you can just connect and forget. Meaning the battery is never at risk of overcharging because the charging will resume when the battery life is depleted and stop drawing current at 100%

Unlike other NOCO chargers, NOCO Genius GENM1 allows the use of extension cords without any specification. The microprocessors inside the charger are capable of variable input compensation at varying AC input voltages.

GEN Mini 1 comes with a 5-year limited warranty​

8. NOCO Genius G750 - Best Compact Barttery Changer

The NOCO Genius G750 makes it into our list as one of the bestsellers among the NOCO products.

This battery charger has the capability of fully charging a drained battery ranging from lead-acid to gel cell batteries.

It is compatible with a long list of battery types found in most vehicles. Its versatility to function well on different vehicle types is one of G750’s selling points.

G750 serves as both charger and maintainer maximizing its portability for both 6V and 12V batteries.

There are two battery charging modes to choose from, easily differentiated by the voltage used. They can be interchanged through a switch. Don’t worry; G750 automatically memorizes the last selected mode when restarted

What makes this battery charger superior to the traditional automotive battery charger is its ability to charge the batteries two times faster because of the high-frequency and high-efficiency platform. The energy consumption is thereby minimized because of this.

One other main feature is its built-in battery desulfator that recovers worn-out or deeply discharged batteries. It can rejuvenate these said batteries through pulse charging until they bounce back again.

Charging process of G750 is controlled by the onboard microprocessors which provide five steps towards the maintenance phase where the battery voltage will constantly be monitored to determine if a maintenance charge should be done.

The battery charger can then be left connected indefinitely without any risks of overcharging. Unlike other automatic battery chargers which are susceptible to overcharging, G750 doesn’t conform to their methods.​

From its external design, it can be noticed that the electrical outlet connector is located directly at the back of the unit. It’s unlike the other battery chargers that have connector plugs which lengthen the reach of the battery charger without a need of extension cord.

​However, for G750, the housing also functions as a plug and takes much space when connecting it to an AC outlet. NOCO discourages its patrons from using extension cords as a safety precaution unless it’s absolutely necessary.

The exterior of the G750 pertains to its portability because of the 4.4x2.7x1.3 inches dimensions and 0.2-lb weight. It has a robust construction with IP60 classification making it dustproof and water-resistant.

Aside from the 5-year warranty, other features to watch out are the spark-proof cables (alligator clips and eyelet terminal connectors). Like other battery chargers, there’s a reverse polarity protection through an orange LED light.

9. Schumacher SC-1200A SpeedCharge - Best Portable Battery Charger

Schumacher SC-1200A SpeedCharge makes it into our list mainly because it’s not just a charger.

It’s also a maintainer and a tester that is virtually applicable to different types of batteries and most battery sizes.

Either the battery is a 6V or 12V, this one has auto adjustments on its amperage to charge batteries quickly.

SC-1200A is microprocessor-controlled, and by that, it has a multi-stage charging process that will charge a battery 2x faster compared to conventional chargers.

The charger constantly monitors the battery condition and may adjust the charge rate downward in an attempt to prevent battery damage. You can leave it on indefinitely as the charger quickly switches to float mode at full charge to maintain the battery.​

This battery charger is quite big and heavy. Its dimensions are 9.8x7.6x3.5 inches, and at the 3.1-lb weight, portability is not its priority.

You may find the cable length to be short as it only measures 6 feet. Cable connectors are only available in 50A alligator clips.Schumacher doesn’t recommend the use of extension cords unless it’s absolutely necessary.

Share Top 10 Car Battery Charger Reviews  With Who Might Need This!


Best Car Battery Charger 2017 - Buyer's Guide

​Other ways to solve a dead battery problem is to hire a fellow motorist or call a friend mechanic. Some others end up buying a spare battery to store inside the trunk. But this is not always practical for some drivers.

​Battery chargers are applicable to any vehicle such as ATVs and motorcycles. There are many different kinds of battery chargers, but we’ll focus primarily on cars in this article.

Choosing them is kind of difficult especially to newcomers who just started driving recently. There some terminologies which might be your first time hearing

It’s important to be emphasized that getting the wrong battery charger not applicable to a particular vehicle type can cause damage not only to the charger but also to the vehicle. Car battery chargers have different specifications, and this guide will somehow help you choose your first charger.​

  • Battery Type

Battery chargers for cars vary depending on the power sources used. Some common car batteries are flooded, gel cell, AGM, etc. Flooded or wet cell batteries are the most common for cars and may come in conventional or sealed versions.

The latter don’t need much maintenance as there’s no frequent adding of water to be done. But for conventional flooded batteries, they need continuous replenishment of distilled water because the electrolytes are easily spent when charging. These are common in classic cars, but they’re still available today.

Gel batteries, on the other hand, are batteries which use the gel-like substance in replacement of water for the previous battery type mentioned. Gel cells are picky when it comes to battery chargers, but a few models can work with gel cells and other battery types simultaneously.​

  • Jump-Start Potential

​Jump-starting a dead battery with a battery charger is the same as having another car do it. The principle involved is transferring electricity from the battery to the other by sending an enough amount of amperage to start the car.

A car’s battery is said to require high amperage or cranking amps for a short time to start it. A 300-CA should be able to do it. But there are times it’s harder to jump-start the dead battery in cold weather. Depending on the temperature, the cranking amps or specifically cold cranking amps (CCA) becomes higher.

Jump-starting the car battery has its risks, though. You need to have a high-performing equipment with right connections to avoid damaging the battery and other electronics most modern cars have. In short, you need to know how to jump-start a car properly.

Know that this feature is not common with most battery chargers. This means that a battery charger with a jump-start potential means more bucks to be spent.

  • Amperage

​Get yourself a charger that has a high amount of amperage per millisecond. This means that the battery delivers more current at a fast rate without risk of damage. It also a good sign to tell the overall charger quality.

  • Charging Time

​Car battery chargers can range from 2 to 12 hours charging time. Indeed, it varies greatly depending on the level of the charger.

It’s common sense to assume that the quicker the battery charges, the expensive it would be. Price also indicates the portability of the device, and so, small chargers that can fit into your palm have quick charging times.

  • Cable and Clamps

​Longer cables are best preferred because they offer movement when you’re jump-starting the car. The length is something you should consider as a safety feature. Another thing is the insulated clamps.

The car battery charger should be insulated to protect you from electric shock. Spark-resistant clamps reduce the sparks that fly off when the cables are connected to the car’s battery.

  • Reverse Polarity Alarm

​This safety feature is most applicable for first-timers. The alarm goes off from the battery charger when you connect one cable to the wrong terminal. Connecting both of them can seriously damage the battery and the charger, though.

There are times that some experienced users can be absent-minded when connecting wires, so this feature is always great to have.

  • Automatic Charging

​Most battery chargers of today have automatic shut-off feature as soon as the battery becomes fully charged. This prevents damage to the battery because of overheating and overcharging.

Two methods are currently used: by resistors/capacitors and through microprocessors. The former has a risk of failing while the latter have different charging stages.

Conclusion

​The ten listed above are all used by many car owners because they have certain safety features and display good performance which set them up on the scale.

Don’t look for others; the best car battery charger is surely one of the above as long as it matches your preferences. Buying a car battery charger is best recommended, so you’ll become prepared when the unwarranted happens.

If we are to pick our top two car battery chargers, they are the NOCO Genius GENM1 and CTEK (56-158) MULTI US 3300.

This makes it OK to use the charger without fearing it to get damaged if it accidentally becomes wet. Other things which make it superior to other chargers are the fast charging, recover fully drained batteries and the free use of extension cords.​

For the CTEK (56-158) MULTI US 3300, what makes it better than the others is its unique way of charging sulfated batteries. It uses a patented method exclusive to CTEK. One more thing to admire is the three modes that you can select depending on the size of the batteries.

The first two modes are the battery sizes, and the last one is called snowflake mode – which enables the charger to function well at cold temperatures. Other features on what makes it unique are the following: water and dust resistance, automatic current charge adjustment depending on temperature, and extends battery life 2-3 times​
