Jumping into your car to find that the battery is flat can be very frustrating. If this has happened to you, using a smart car battery charger that safely restores power to a dead battery is highly recommended. Luckily, there is plenty of chargers to choose from and all of our recommendations are suitable for the UK market because they plug straight into a socket.

If you require a quick answer, the best car battery charger is the CTEK MXS Series, which is available in various amperage ratings and is designed to safely charge a range of battery types. However, if you require a more affordable alternative that’s manufactured by a reputable brand, the AA DFC150 is a great option to consider.

To rate the car battery chargers within this article, we based our recommendations upon our experience and testing of multiple chargers. We also carried out hours of research and considered a number of factors. Some of the factors that we considered included the amperage rating, smart functionality, safety features, display, build quality, warranty and value.

Car Battery Charger Comparison

Car Battery ChargerSmart FeaturesAmperage
CTEK MXSYes3.8 to 10 Amps
NOCO Genius 5Yes1 to 10 Amps
Ring RSC612Yes12 Amps
AA DFC150Yes1.5 to 4 Amps

Dealing with a dead battery can be fairly problematic and although you may be able to use a jump starter, it isn’t the safest method. This is because it sends a spike of voltage to the battery to help you start the car. Instead, allowing the battery to fully regain its lost power is highly advised because it won’t cause any damage to the car’s electrics or battery.

The latest selection of smart battery chargers are far more sophisticated than they once were. Manufacturers have focused on improving safety, introducing automatic modes and even optimising the condition of the battery.

Below is a list of the best car battery chargers that are suitable for use in the UK and include multiple smart features to safely recharge dead batteries.

How We Rated The Car Battery Chargers

Due to the fact that we own a number of cars, we often find ourselves topping up the charge on all of the batteries because the cars aren’t always driven regularly.

Over the years, we’ve tried a range of battery chargers but because we tend to use them quite often, we decided to invest into the premium CTEK MXS 10 to keep our batteries maintained. Needless to say, we certainly weren’t disappointed with it and it’s a far better car battery charger than any of the devices we’ve previously used.

As you can see in the photo, the CTEK charger allows us to track which stage of the charging process the battery is at via the LED indicators. You can also see the build quality (clamps, protective sleeve and wires) is at a much higher standard when compared to most of the alternatives on the market too. As well as the CTEK MXS, we’ve also had experience with the NOCO, Ring and AA chargers and they are also great options to consider by reputable brands in the UK.

Along with our experience and testing of multiple car battery chargers, we also based our recommendations upon hours of research and a number of factors. Some of the factors that we took into consideration included the amperage rating, smart functionality, safety features, display, build quality, warranty and value.

Below is a video that we posted onto our Instagram page that shows us testing the CTEK MXS. As you can see, it moves through the stages to give us an idea of its charge status.

This is a great feature to have because it means that you don’t have to rely on guesswork. Once it reaches the latter stages, it also indicates whether its fully charged or on an automatic trickle charge too.

Car Battery Charger Buying Guide

In order to restore power to a dead battery, you’ll require a car battery charger. They are available in a variety of different power ratings that range from as little as 0.75 amps to as powerful as 26 amps.

Along with the choice of amperage ratings, there is also a range of types that include a standard, trickle or smart car battery charger. Regardless of the model you choose, by owning a charger, you’ll always be able to restore power to a battery. To help you make an informed buying decision, we’ve produced the below guide regarding car battery chargers.

Different Types of Chargers

Battery chargers have seen a huge amount of improvement over the last few years. This is because manufacturers have been competing with themselves to produce the best, which has resulted in a variety of different types being available. The main types include a standard charger, trickle charger and the highly recommended smart battery charger.

Standard/Basic

Standard chargers are the cheapest and they simply charge a battery at a fixed current until it’s fully charged. However, it’s important to note that not every charger will automatically switch off once the battery is fully charged and this may result in overcharging. This can be damaging to the battery and its why you must monitor the charging process when using this type of charger.

Trickle Charger

The purpose of a maintenance/trickle charger is to keep the battery topped up without overcharging or causing damage. They are designed to provide a low current to the battery in order to maintain its optimum power. This type of charger is perfect for those that have cars they only drive on the weekends or when it’s occasionally sunny in the UK.

Smart Car Battery Charger

By far the best battery charger for cars is one that’s “smart”. In short, it’s a combination of both the standard and trickle charger types but they also include extra features such as:

  • Additional safety functionality
  • Diagnostic tests
  • Battery repair modes
  • LED display
  • Various charging modes
  • … and so much more

If you are able to stretch your budget, we would highly recommend opting for a smart battery charger.

Amperage Rating

Many brands offer multiple amperage options with their chargers and the higher the amperage, the faster your battery will charge. However, the battery size will determine the length of time it takes for the charger to restore any lost power.

As stated by NOCO, you can calculate the time it takes to charge a battery by multiplying the battery amperage per hour by the depth of discharge. This’ll provide you with the total number of hours required to achieve maximum charge.

In short, if you require fast charging, you should choose a car battery charger with a high amperage rating.

Cables and Clips

Battery chargers need to be able to withstand tough conditions and heavy usage. Therefore, to ensure that the device you choose is long lasting, you’ll want to make sure that the cables and clips are constructed of high quality materials. A good sign that they are built to last include thick copper leads and insulated battery clips.

How To Charge A Car Battery

In terms of using a car battery charger, there are two methods of charging batteries. You can either leave the battery installed without any load or alternatively remove the battery to charge it.

Battery Left in the Car

Removing the battery in some cars can involve quite a lot of effort, which means that leaving it installed may be the best option. Before you connect the charger, it’s important that you ensure all electrical loads are switched off. To ensure that this is the case, you’ll want to remove both the negative and positive cables from the terminals

Some vehicles may suffer electrical malfunctions if you connect the charger with the battery under load. Although it may be safe to do so, we always recommend removing the cables from the terminals for peace of mind.

Removing the Battery

Taking the battery out of the car and placing it indoors is the safest option and it can sometimes be easier too. For example, not all battery chargers are waterproof and you may not be able to run an extension cable to your car.

When you come to installing the battery back into the car, we advise that you double check it’s placed back correctly. This means checking the terminals are next to the matching positive or negative cables and that it’s secured within the battery tray. The RAC have a great guide if you need any further assistance with regards to installing the battery.

Compatibility

Almost all car battery chargers are compatible with lead acid batteries. However, not every charger will be compatible with lithium-ion, AGM, gel or wet cell battery types. Therefore it’s crucial that you double check the battery you have installed in your car is compatible with the charger to avoid any disappointment.

Many chargers may also work with other types of batteries that are used for lawn mowers, caravans and marine applications. Therefore, spending slightly more for a charger that’s compatible can be very beneficial.

Conclusion

Without having access to a car battery charger, you can be left literally stranded with a dead battery. Although you could jump start your car, doing this regularly isn’t advised and it can potentially cause damage to the battery and your car’s electrics. Instead, fully recharging your battery to its optimum condition is the best and safest option.

All of our recommendations listed above are suitable for a range of budgets and cover all the different types available in the UK. Although its not something you use all the time, it’s certainly a device that can save you a lot of time and hassle.
