Top 15 Best Car Battery Chargers in 2020

Top 15 Best Car Battery Chargers – Complete Guide & Reviews 2020

Owning a motor vehicle means dealing with several malfunctioning parts and visiting auto servicing shops numerous times during its lifetime. One component that no car owner wants to deal with is the battery, simply because it’s both inconvenient and expensive to replace it. A car battery charger is a handy tool to recharge the battery when the latter drains out for some reason.

Car batteries cannot sustain themselves. They receive charges from either alternator (in modern cars) or dynamo (in older cars), which is a type of generator. When this generator fails, the battery will be dead after a while and can leave you stranded in the middle of nowhere. A charger can get the vehicle up and running again in a moment.

A charger delivers a small amount of charge over a period of time, helping the battery to maintain the minimum required voltage and amperage. It does not supply a huge amp surge to the starter motor, not allowing to jump start the vehicle. But some chargers have the jumper option so you can deal with a dead battery.

Types of Car Battery ChargerTop 15 Best Car Battery Chargers in 2020

All car battery chargers do one thing—supplying electrical charge to the car battery. But some units may have more specialized functions, leading to a different category. Here are a few different types, according to their functions:

1# Maintainer

As the name shows, this charging unit not only recharges a battery but also does some cell maintenance. It falls in the middle ground between a charger and a jump starter as it cannot recharge a dead battery or has enough power to restore the cells to their former condition.

It can keep a battery alive only when the latter has some juice left in it. There is no universal maintainer model. You have to choose a model according to the car battery type.

2# Charger

It refers to the standard battery chargers and comes with various types of amperage and voltage ratings. There are chargers for all types of motor vehicle batteries.

3# Restorer

The least common type of all variations because its charging function is only an add-on. Its main function is breaking down sludge and dirt buildups inside the cells to restore a battery’s normal function, which is holding electric charge.Top 15 Best Car Battery Chargers in 2020

You don’t need this expensive type unless you own a fleet of motor vehicles or have plenty of car batteries to use for some other purposes.

4# Automatic vs. Manual

You can also divide the chargers based on this criterion. Autonomic ones are the most convenient as they automatically stop supplying charge to the battery when the charge is full. Overcharging affects battery life so they increase the battery life. On the other hand, you need to switch mode manually in a manual charger when the recharging is done.

It’s also possible to divide the chargers by their power rating, which refers to voltage and amperage. You should check both these ratings to see whether a charger is compatible with your vehicle’s battery. A standard battery is 12V, but there are chargers that can recharge anything from 6V to 48V. So, you will find a charger for every vehicle type—from a go-kart to an industrial truck.

Similarly, chargers have various amperage rating, which determines how quickly the charger can charge the battery. Every battery has a maximum amperage rating and charging it at beyond that rating can damage the battery or the charger.

Preferred Safety Features in Car Battery Chargers

Using a car battery charger means you are handling the battery on a motor vehicle, and this task demands employing some safety measures. Overcharging a battery could cause irreparable damage and even accidents.

Overcharging triggers extreme gassing, overheating the electrolytes and leading to the production of both oxygen Top 15 Best Car Battery Chargers in 2020and hydrogen. These gases ruin the plates in older vented batteries. The gas buildup could even burst sealed batteries. Another safety hazard is the harmful chemical elements in the batteries.

So, car battery chargers should have some safety features to minimize the risk of accidents.

Auto shut off: This feature prevents overcharging and overheating the battery through automatic detection of amp and volt.

Spark-resistant clamps: A spark from the car battery could be devastating. It can ruin the engine and lead to dangerous fires. So, a charger should resist sparks to safeguard the battery.

Reverse polarity: Connecting the charger to the wrong battery terminals may ruin both units. If the charger has the reverse polarity feature, you can interchange the terminal connections without causing any harm.

In addition, some other safety measures that should be in high-quality battery chargers are battery diagnostic, jump start, trick charging, enough jumper cable length, and maintenance mode.

Characteristics of High-Quality Car Battery Chargers

Want to purchase a car battery charger? The best way is to learn about the features to look for. Of course, you would prefer a high-performance charger that also takes care of the battery health. Can any charger do these things? You can say so if it has one or multiple of these qualities:

Size & PowerTop 15 Best Car Battery Chargers in 2020

A charger should come in a size convenient for moving from one place to another. Once upon a time, the charger was as large as the battery itself, which is not practical. You cannot keep it on hand everywhere you go.

Thanks to the advanced technology these days, the size has been greatly scaled down. Some models fit right onto your palm and you can stash others in a small bag or the car’s glove box.

However, a large number of units are not that small but they should be compact so you can move them easily from one place to another. You should not trade off performance and features for size, but small-scale, light units are convenient to carry around and use. These smaller units can charge various electronics such as cellphones, laptops, and more.

The next thing to focus is the power, which refers to the amperage and voltage ratings. Amp refers to the total electrical load the charger can handle or pass through it without causing any damage. A high amp rating means the charger can transmit a high amount of current through it, resulting in faster charging. However, quicker charging can be harmful too in some cases as it can warp the battery plates.

When a car battery has 40-amp hours rating, it will take a 10-amp charger around 5 hours to top it up, given the battery is completely dead. A charger can range from 6 amps to 20 amps. On the other hand, volt refers to the electric strength of the charger.

Having higher amp and volt ratings mean a charger can hold a high electrical load and don’t take much time to recharge a battery. However, more volts and amps increase the price. A high-quality charger is supposed to have settings for automatically selecting the correct rate of charging a battery.Top 15 Best Car Battery Chargers in 2020

Performance & Other Features

Like all high-quality electronics and tools, a good charger should be user-friendly. It’s not about having plenty of features, but only those ones that are practical and useful. For example, indicators for performance levels or USB slots for charging devices other than an automobile battery are nice add-ons.

A good charger is likely to have small LED lights for indicating various functions such as battery power, reverse polarity to avoid connecting to the wrong terminals, full-charged state of the battery, and more.

Different charge phases are a handy feature for car battery chargers. A charger with this option provides better performance. These chargers can decode a battery’s electrical signals to figure out its actual charging state. They will then adjust the settings to ensure the most efficient way of recharging. Another useful option is detecting the battery’s charged state and cut the power supply to prevent overcharging.

Water and dust can do substantial damage to a battery charger. Some units are designed to withstand these elements. You have to check for the IP rating of the charger, and different ratings indicate different levels of protection.

In addition, a battery charger can have various types of safety features, including float mode, clamp amp, spark-proof clamps, battery tester, reverse polarity alarm, and more. These functions not only protect the car battery but also the user.

FAQs about Car Battery ChargersTop 15 Best Car Battery Chargers in 2020

Is it harmful to keep a charger attached to the battery for an extended period?

Yes, it increases the chance of damaging the battery. If you often forget to disconnect, buy a smart charger that cuts power supply automatically when the battery is full and resumes when the battery needs a top-up.

Can you leave a battery charger plugged in?

Yes. A charger draws power from the car’s cigarette lighter outlet. You can leave it plugged when using a low-amp charge.

What is the ideal charging frequency?

Regular driving does not require additional charging. But if the car sits for a long period, like for weeks or months, it may need to be recharged from an external source. If you are going to leave the car idle for a year or 6 months, use a charger at least once in a month.

Can a dead car battery be recharged?

Yes, but not all chargers can provide this service. Sometimes, you may need to jump start the battery to make it run again for receiving charge. A few charging units have this jump start function. But the battery won’t respond if it has a dead cell.

If you don’t have the time to do online research, don’t worry. We’ve done that for you! Here’s a list of 15 simple and efficient car battery chargers. Check all the products because they have different functions, features, and prices.

There is a 12V repair mode that automatically detects sulfation and acid stratification and then repairs this condition. It also has several indicators including a gauge for showing battery charge.

NOCO delivers a user guide with the product, but it’s so small that you will need a magnifying glass to read the instructions. You will get a 3-year limited warranty for the product.

Performance & Other Features

Most chargers either overcharge or undercharge the battery. NOCO solves this problem by adding a thermal sensor to Genius5. This sensor detects the environment temperatures and adjusts the charging rate accordingly.

A Force Mode is there to charge batteries at 1V. At this mode, the charger manually charges the dead battery. It also maintains the battery’s health to ensure a longer lifespan.

Genius5 may take longer than suggested in the user guide to charge a discharged battery. It happens because the first ‘25% charge’ step involves a de-sulfation process and the last ‘100% charge’ step includes an optimization process. Completion of the ‘50%’ and ‘75%’ steps takes little time.

Pros

  • A lightweight, handheld charging device
  • Delivers several functions
  • Charges and maintains a battery
  • Temperature detecting sensor

Cons

  • Small user manual
  • Charging takes several hours
