The CTEK MXS 5.0 has a compact design and is suitable for any battery type. It has an operating voltage of 12 V and has a high capacity and fully automatic 8-step charge cycle.
The MXS 5.0 has a dimension of 18,8 x 6,5 x 3,8 cm and a weight of about 600 g. This makes it a compact and practical charger. Its shape allows you easy handling and convenient use.
The device can charge any type of car battery, except lithium-ion batteries. Saves you from searching for a suitable charger.
With a capacity of 110 ah, the MXS 5.0 charge the battery quickly. Through its intelligent charging process, the charger maintains the battery and ensures step by step that everything is in order during charging.
Here, all the stages of the charging process are presented in more detail:
- At the beginning, the battery is first desulfated.
- After that, the charger checks the battery’s charging capability. If the battery is defective, the charging process is interrupted at this point. If the battery is functional, the actual charging process is continued.
- The battery is now charged at maximum current until it reaches a state of charge of 80%.
- In the next step, the battery is charged – in order to preserve it – with a progressively weaker charging current until it reaches a state of charge of 100%.
- Now the charger tests the charge maintenance of the battery. If the battery can not hold the charge, it indicates a defect.
- In this step, the reconditioning function can be used to breathe new life into old batteries.
- The battery voltage is now maintained at the maximum value by charging it at constant voltage.
- Battery capacity is maintained at 95 to 100% (trickle charge). The charger monitors the state of charge and gives a charging pulse if necessary.
Short circuit protection / reverse polarity protection / overload protection / overheating protection / trickle charging
From a safety point of view, the MXS 5.0 without doubt optimally equipped. In fact, it has all the important protective functions. In addition, its trickle charge allows a smooth and continuous charge.
Short-circuit protection, reverse polarity protection, overload protection and overheating protection: the MSX 5.0 ensures complete protection against the most common hazards. Thanks in particular to its intelligent microprocessor, it can detect power problems at an early stage and react accordingly. The charger reliably protects the car’s electronics from short circuits and incorrect connection attempts.
In addition, the MXS 5.0 protected against dust, splash water and sparks thanks to IP65 protection rating.
With its trickle charge function, you can leave the charger permanently connected to the car battery. The MXS 5.0 recharges the battery every time it is discharged. For this, the device ensures that no power is supplied unnecessarily and the battery is always maintained.
Battery test / automatic shutdown / cigarette lighter plug
By means of its microprocessor, the device can perform a complete battery test and perform many tasks automatically. However, it has no plug for cigarette lighter.
The charger has a microprocessor that can detect the state of the connected battery and automatically recharge it according to its state through an 8-step charging function. It also detects defective batteries that cannot be recharged and must be replaced instead.
Thanks to the refresh mode, the battery lives again and is fully operational in a short time.
The MXS 5.0 can apply different charging programs depending on the battery size. Normal batteries are charged mainly with 5 A, whereas small batteries need a charging current of only 0.8 A.
The use of the device is very easy, thanks to the intelligent automatic charging system. Even complete amateurs can use it without problems. In fact, you can follow every step of the charging process through a user-friendly LED display.
In addition to the above test and diagnostic function, the device also has a special reconditioning function. This allows even deeply discharged batteries, which would otherwise not be able to be recharged in any other case, to be made fit again.
In addition, the MXS 5.0 a desulfation function. Its task is not to let sulfates deposit on the lead plates of the car battery. In this way, the device protects the battery from a loss of power, which can shorten the life of the battery.
One of the downsides of this charger is that it doesn’t have a plug for the cigarette lighter.

Guide: questions you should ask yourself before buying a car battery charger
What are the advantages of car battery chargers??
The first advantage of a charger is the time you save. With a charger you don’t have to wait to be helped. In other words, no need to tow the car or use other people’s cars.
Moreover, you do not have to be annoyed by possible malfunctions. You don’t have to take your car to the garage or buy a new battery.
In general, chargers have shown to bring versatile advantages and to be really helpful to the user.
You can also save money with a battery charger. Although a charger also costs money, it is no more expensive than a new battery. Considering the benefits of these devices, it is worth investing the money.
Not to mention that a charger usually lasts longer than a car battery and can be used for several vehicles.
When a car battery charger is most often used?
- Vehicles with seasonal license plates that are not moved over the winter.
- Vehicles that are left in an unheated room over the winter.
- If you have a vehicle that you drive daily for short distances.
- Car batteries that have been accidentally discharged.
- There are no other vehicles nearby to bridge the gap when your own car is out of service
- does not start when you try to start it.
- When in the early morning (especially in winter) the car won’t start and you don’t have time to charge it.
How much does a car battery charger cost??
You can find the most different types of devices. On the one hand, we have the simple chargers from the hardware store, which are often very slow, not robust and with a very short useful life.
Moreover, they can even damage the car battery and have no additional functions. They typically cost between 15 euro and 20 euro.
|classic car battery charger
||ca. 20-150 €
|LG for cigarette lighter
||ca. 15-40 €
|solar battery charger
||ca. 20-80 €
On the other hand you can find the fully equipped models. These include all possible functions, work quickly, do their job automatically and often flawlessly. The price of such chargers goes from 70 to 150 euros.
In addition, solar battery chargers and cigarette lighter chargers tend to cost less than standard car battery chargers with numerous functions.
How to use a car battery charger?
First, you should already know these facts:
Normally, the charger consists of a red cable with plus pole (+) and a black cable with minus pole (-) in the front, and a power cable in the back, which must be inserted into the socket.
Clamps are mounted on the battery terminals. For safety reasons, the clamps should be removed to ensure that there are no problems with the current.
If you connect the terminals incorrectly or set the voltage too high, the fuse of the device will blow. But this should not be the case with modern chargers, as they are equipped with intelligent charging electronics. This can automatically adjust the charging current as well as the voltage.
Just follow these steps:
- Open the hood and remove the battery cover.
- Disconnect the on-board power supply: first remove the minus pole (-), then the plus pole (+).
- Connect the charger: first disconnect the positive terminal (+), then the negative terminal (-).
- Plug the charger into the wall socket.
- Wait until the battery is fully charged.
- Disconnect the charger: first remove the negative terminal (-), then the positive terminal (+).
- Connect the electrical system: first connect the positive pole (+), then the negative pole (-).
If you need it, you can also see the procedure visually in the following video.

- Battery store
- Car Parts24
All the chargers that we present on our site are linked to the above mentioned stores. So that when you find one that you like, you can go for it.
Are car battery chargers the best alternative?
The charger can be seen as the logical consequence of the development of vehicle auxiliaries. It is the result of new and old ideas that have come together to create a new product.
This does not mean that new ideas are always better than the older ones. You can really judge a new concept as better and more valuable only if it seems to have an improved performance in all parameters. In chargers, compared to other means, the results are quite unique.
Did you know that in case of emergency you can charge your car battery with a motorcycle battery charger??
But you have to keep in mind that this will take longer than with a car battery charger and that it may take a while. Does not work if the car battery discharge is faster than charging with the motorcycle battery charger.
That is why it is particularly difficult to find a similar product that has the same features and benefits.
What are the most common problems with chargers?
- The so-called superimposed voltages. It is high voltages that endanger electronic components in the car.
- Very slow charging of both car batteries and charger.
- Sudden malfunction
- Car battery damage
- Display that shows wrong information: z.B. Fully charged battery.
- Charger that works in some cases and not in others.
Decision: what types of car battery chargers are there and which is the right one for you?
Basically, there are three types of battery chargers:
- Standard car battery charger
- Cigarette lighter charger
- Preservation solar device
Each of these loaders performs a similar function, but they can be differentiated in different aspects.

Each charger has its own features. chargers can differ in the types of batteries they support, the charging current, the additional functions that revolve around charging the battery, and other features.
You can consider the first type as the starting point. The other two are a further development of this standard product.
Depending on your needs and preferences, a certain type of charger is suitable for you. In the following section we will help you to find the best solution for you.
To do this, we present you all the above types of chargers before, including their advantages and disadvantages.
Remember that it is not always easy to attribute a product to a particular category.
What is a classic car battery charger and what are its advantages and disadvantages??
This type of charger is directly connected to the car battery. Nowadays, these devices have several functions and are more sophisticated than older models.
A classic car battery charger has a red and a black cable, just like a jumper cable. They are connected to the car battery to charge it. To connect the device in the best way, you should follow a correct procedure. More about this we present you in the following on this page.
Nowadays almost all car batteries are "maintenance free" batteries. This does not mean that they will run without problems and you do not have to take care of them. There are always cases when a car battery can be damaged or needs help to work best.
Therefore, a charger is one of the best tools, as it allows us to avoid buying a new one and incurring further costs.
Such a device is perfect for people who often drive short distances. Because of the constant starting and stopping of the engine, the alternator has too little time to supply enough current. In this way, the battery is overloaded too much. In the long run, the battery will get less and less current and eventually discharge.
- Fast charging
- Compact and handy design
- Many automatic functions
- Control LED
- Connect directly to the battery
- Relatively short usage time
The charger is also very useful for vehicles that stop for a long time. If a vehicle is not moved regularly, its battery can lose power very quickly. Especially if you leave your car in the garage over the winter, because the cold can damage the engine or break it completely. That is why a charger is the perfect solution to supply the necessary electricity permanently.
It can often happen simply that when leaving the car, an electrical consumer is still in use. If you do not notice this, the car will not start the next time you turn the ignition key.
For this reason, it is highly recommended to charge the battery periodically. This can not only save you from damage, but also prolong your life!
chargers can have different and interesting functions that have been developed over time. Some models can be called "intelligent", in the sense that they can do their job automatically. Therefore, it is worthwhile to have a certain level of specific expertise. Below is a list of such functions:
- Immediately check if the battery has absorbed the current and is fully charged.
- Pulse charging maintenance function, which means that you can leave the charger permanently connected to the battery without stressing it.
- The device knows when the battery needs power and when it doesn’t. This function is especially important for vehicles that have z.B. To be charged constantly during the winter.Provide additional starting assistance, just like jump starting a second car.
- Temperature control used to prevent damage to the battery.
- Keep the user informed with a display.
- Avoiding overcharging after charging.
In addition, more and more chargers are integrated in so-called powerbanks. These can not only charge the car battery, but also smartphones, tablets, laptops etc. With the help of different adapters, it is also possible to charge navis, digital cameras and many other devices while on the road. There are even devices that are equipped with an SOS function and leds emergency light.
However, it must be said that you should avoid a completely discharged battery in any case. This is because it is difficult to jump start a car with a completely discharged battery, even for very good models.
But in some cases, the battery still has a chance, because if the battery was only deep-discharged for a short time, some chargers can recover it. However, the charger must support a special charging program for this purpose.
Finally, we point out another feature of the product. Typically, the useful life of the device ranges from 1 to 3 years. For certain people it may not be enough, especially if they have bought an expensive product. Basically, the choice of chargers is varied and depends on your needs.
What is a cigarette lighter charger and what are its advantages and disadvantages??
This charger basically works like a USB adapter. It is connected directly to 12V cigarette lighter through a cable.
This category of chargers is the best solution if you want to use a quick and easy device. This can be the case when your car does not start. Or if you don’t have time to open the hood and remove the battery cover.
In these cases, you can simply take the charger in your hand and plug it into the cigarette lighter socket.
- No technical know-how needed
- Very quick to use
- No dirty hands and tedious plugging in
- Control LED
- Compact design
- Weak power during charging
- Significant risk of overheating
- Relatively short service life
It is important to make sure that the voltage of the charger matches the voltage of the connected device. The charging current of the charger must be at least as high as that of the connected device. This is especially necessary if you want to avoid overheating of the charger.
Moreover, it is necessary to know that such a device is not the most powerful one. In fact, it cannot fully recharge a deeply discharged battery, even if it manages to start the car.
As in the case of any charger, in order to provide your car with concrete starting assistance, the car battery must have at least 20% power.
What is a conservation solar device and what are its advantages and disadvantages??
It is a mobile charger which is charged by sunlight. To charge the solar charger, simply place it in the sun or in daylight.
A solar charger for car batteries is easy to recognize: a large part of it consists of a solar panel. its work is to catch the sunlight and store it in the charger.
Normally the charger is connected to the cigarette lighter via a plug. There are also models that you can connect directly to the battery with cables. Of course, the shelf is the best place to get pleasant sunlight.
- Pure solar energy
- Easy to use
- Control LED
- Weak performance when charging
- Risk of overheating
- Electricity can disappear
- Relatively short usage time
- design can be awkward
Depending on the model, there are two different modes of operation. With some devices it is necessary to use the power immediately, because the device cannot keep it for a long time. With others, the energy is stored in the integrated battery for later use.
In addition, you need to know the voltage and charging current of the device when choosing, otherwise it can cause problems with some types of plugs.
This device also lacks sufficient electricity. In fact, it cannot fully recharge a deeply discharged battery.
Buying criteria: these are the factors you can use to compare and evaluate car battery chargers
In the following section, we will show you which factors you can use to compare and evaluate car battery chargers. This will make it easier for you to find a charger that is as suitable as possible.
In summary, these are:
- Operating voltage
- Max. Capacity
- Charging cycle
- Battery test
- Short circuit protection
- Reverse polarity protection
- Overload protection
- Overheating protection
- Trickle charge
- Automatic shut-off
- Plug for cigarette lighter
- Supported battery type
In the following paragraphs, you can read about each of the buying criteria and how you can rank them.
The size is an important factor that can help you evaluate the compactness and portability of the product.
Of course, you know that the smaller a product is, the better you can carry it. With a compact charger, your charging work will be more comfortable and easier. Therefore, a device with limited mass is preferable.
Nowadays, most of the devices are very handy, even if they are quite big.
In addition, you should pay attention to the fact that a small size is not a sign of poor performance.
It can often happen that at first glance there seems to be a direct correlation between size and power. However, you can find many products that are generally better than those that look bigger and stronger from the outside.
Who wouldn’t want a compact product that you can put in the glove compartment??
In the product characteristics, the size is specified in centimeter (cm) shown, where the first number refers to the length, the second to the width, and the third to the height.
Similarly to size, weight also represents an important factor that indicates the convenience and portability of the product.
The advantages of a lightweight device are obvious and recognized. You can easily carry it and use it without any assistance.
Besides, there are hardly any chargers that weigh more than a few kilos. Therefore we have shown the weight in grams.
Technological developments over time have allowed us to manufacture more efficient products in many fields, which are increasingly smaller, lighter and more powerful. This also applies to car battery chargers.
It is therefore very unlikely that you will find devices that make it difficult to charge your car battery.
This is the voltage for which the charger is suitable and it is specified in the voltage range volt (V) measured. This number shows you what voltage the charger must have in order to give the best power supply.
12 V is the most common voltage you will see. Of course you can find 6 V or 24 V as well. When a device has z.B. If the charger has a voltage of 12 V, it means that the receiver must also have 12 V.
Different tensions exist because there are essentially two types of tension groups:
- Low voltages, which simply require a copper wire wrapped in plastic.
- High voltages that can only flow in a more complex wire. This wire is wrapped by an outer layer, which consists of several important materials. This is absolutely necessary because a copper wire is not capable of withstanding high voltages correctly.
devices with different voltages can not be connected to each other, otherwise it can cause problems. The most possible of them are:
- Current surges that damage the insulation.
- Increased temperatures, which also damage the insulation.
- The so-called "mechanical load", i.e. the voltage supplies a pressure that is too high.
Therefore, before buying, always make sure that the charger has a suitable voltage for your car battery.
This is the maximum capacity, or in other words, the number of maximum charging current that a charger can supply.
The capacity of the charger is expressed in ampere-hour (ah) indicated. An Ah is the amount of charge that the charger can deliver through the wire in one hour when the current is a constant 1 amps (A) is. It is the unit of measurement most commonly used for battery charging. The word capacity should not be confused with other applications. Therefore the word charge carrier capacity the best alternative when talking about batteries and chargers.
You must make sure that the charger provides enough current for the capacity of the battery. Charging can even take several days if the current supplied is too low.
Take for example a 12 V car battery. If you want to find out how much time the charger needs to fully charge the battery, you need to know these two data:
- The capacity of the car battery used in ah is shown.
- The capacity of the charger, just as in A shown.
Let’s take the case that the capacity of the car battery is 45 ah and the capacity of the charger 15 A is. Then you just have to divide 45 by 15 and the result is 3 hours.
Here is another example: if a discharged battery is constantly charged for 20 hours at 5 ampere until it is fully charged, we have a result of 100 ah (five times 20 hours).
This concept is directly related to the charging of the battery. A charge cycle, or full cycle, represents the recharge time of the car battery.
In a normal process, first the battery is discharged to the point where the maximum depth of charge is reached. The discharge goes to the reliable discharge limit. Then follows the charging, until the battery is fully charged. According to this rule, it will half charge cycle called if only half of the battery is discharged and then recharged.
Interestingly, the number of charge cycles must be the same for both charging and discharging. In order to successfully complete a charge, a discharge is required.
Many people have difficulty understanding this concept. But you must know in essence that often a high number of charge cycles corresponds to a technological device.
You must also know that the word "charge cycle" is to be evaluated according to the type of battery, the type of use and other factors. Among the different factors, the discharge current, the depth of discharge, the discharge time and the temperature are the most important ones. Together, these factors have a considerable influence on the number of charging cycles.
Taking the depth of discharge as an example, we can see how the charge cycles change. At a depth of discharge between approximately 10% and 50%, most chargers will achieve the respective number of cycles.
Some models, according to the manufacturer, have a depth of discharge as high as 70% or 80% (five times 20 hours). The most important thing is that you won’t have any problem, as long as you take into account the depth of discharge of the charger.
Did you know that you should not use a car battery charger to charge a motorcycle or moped battery??
This is due to different power ratings of chargers and batteries. Car batteries need more power than motorcycle or moped batteries, so motorcycle batteries or moped batteries should be charged with chargers designed for mopeds or mopeds respectively. motorcycles.
This is a function that allows you to get important information about the battery current. Above all, you can see everything that has to do with current flows and voltage.
In the strictest sense, battery testers are small devices that measure the voltage of a battery and indicate it on a scale or display. There are battery testers that look like chargers, and others that have different contacts for different types of batteries. Therefore, testers are not suitable for all types of batteries. Each test instrument supports one or more specific battery types.
This function is very useful and convenient, so it is a great advantage.
Nowadays, battery testers are also built into chargers. They can occupy only basic measurement functions or also various additional functions. Z.B. In addition to the voltage applied, they can also provide information about the capacity still available in the battery milliamp hours (mah) determine. Mostly the display shows this information in absolute or percentage value.
Battery testers are not to be confused with multimeters. In fact, multimeters are well-known measuring devices that are very rich in functions. Today, most multimeters are digital, whereas analog multimeters are more difficult to find. They can measure voltage, current, resistance of device and terminal, capacitances and even frequencies.
Short circuit protection
As you surely know, a short circuit is to be avoided absolutely. Therefore, it is essential that the charger has a short-circuit protection function.
Everyone has heard of short circuits, but not everyone knows what it is all about.
A short circuit can occur when the poles of two different voltage sources are directly connected to each other. The resulting high intensity current does not meet any resistance.
A short circuit in a battery is not dangerous in itself. Nevertheless, the battery will be fully discharged within a short time, or in the worst case, fires can be caused. Short circuits also occur when the insulation of a cable is damaged or broken.
It is strongly recommended to avoid cheap models. As many comparative tests have proven, inexpensive chargers cannot guarantee enough safety against short circuits.
Reverse polarity protection
This function can be extremely important. Their task is to prevent possible damage when applying electrical voltages in the wrong polarity.
There may be a significant risk of a short circuit if the poles of two different voltage sources are connected directly to each other and a mechanical reverse polarity protection fails. Thanks to this protection feature, you can use your charger without worries. Suitable components and circuits allow a proper functioning of the charger.
The complete name is "electrical reverse polarity protection" to distinguish it from "mechanical reverse polarity protection".
This function is a useful measure against so-called overload currents.
If the total allowable current is exceeded when operating one or more loads, the circuit may be overloaded.
Thanks to appropriate protection measures, cables and wires are protected against overload, usually together with short-circuit protection. In case of emergency, the current is cut off before it damages the insulation, the terminals, the connection points or the consumer.
As you can see from the name, this function is designed to protect against overheating.
This will avoid fires or even explosions when using a charger. Due to increased temperatures and voltages, the various devices and cables can heat up beyond the limit.
therefore, the overheating protection is another means that can give us additional safety.
This function is perfect for vehicles that are left for a long time. This way they do not lose power and have a permanent charge.
chargers that have a trickle charge function can provide the necessary current to the car battery. When a car sits in the garage for months, z.B. Over the winter, the battery loses its power. Therefore, it must be charged continuously.
Moreover, thanks to this function, you don’t have to think about anything, since the current flow is automatically regulated and no unnecessary current is supplied.
This important function can be very helpful and useful for you. In this way, the device will know if the car battery is full and will stop the charging process.
The automatic disconnection can save you not only time, but also money and patience. Thanks to this function, you can leave the charger connected without any problems. There is no risk of damaging the car battery or wasting power unnecessarily.
Chargers that do not have this function do not recognize when the battery is full and continue to supply it with electric current. As a result, you will have additional costs, because it will use far more power than the battery actually needs.
More and more people want to have this useful feature on their devices, because it makes charging much easier.
Another aspect you should consider is the time saved. In fact, you can save a lot of time if you just leave the charger plugged in. This way, you never have to wonder if it’s time to use the charger and make sure there’s no unnecessary power consumption.
Normally, many chargers discharge the battery before they start to fully charge it. But this can lead to another problem.
In some cases, the charger may not only fail to detect a completed charge, but also suck the power back from the battery. In the end, the battery can remain without power, despite the connected device!
Plug for cigarette lighter
This property shows if you can plug the charger into the cigarette lighter socket. Without doubt, it is a very convenient and simple way to use the charger through the cigarette lighter.
Chargers with cigarette lighter option, as said before, are a good way to charge the car battery without much effort. You can simply connect the charger to the cigarette lighter through a normal plug.
Therefore, the presence of this option is an advantage and, accordingly, is evaluated positively.
Finally, note that in the field "battery type" there is a category "standard + cigarette lighter charger". This means that the product can be considered both a standard charger and a cigarette lighter charger.
Supported battery type
The battery type designation shows the type of batteries to which a particular car battery belongs. There are different types of batteries that need a suitable charger to charge them.
The first important distinction involves two groups of batteries:
- Open systems where distilled water is topped up.
- Closed systems, also called "maintenance free" batteries, which are the trend in the battery market.
Generally, car batteries are also known as starter batteries. However, both words are used incorrectly, since the correct technical term is "accumulator. The reason for this is the fact that the accumulator is constantly recharged by the car’s generator.
A distinction can be made between these types of batteries:
- Lead-acid batteries, known as wet batteries, are the most common form of car battery.
- AGM (absorbent glass mat) batteries, known for their lightness. Instead of heavy lead plates, they have a light, absorbent fiberglass layer.
- EFB (enchanced flooded battery) batteries, mainly used in cars with start-stop systems.
- GEL batteries, which contain gelled acid and, because of the strong discharge, are particularly sought after in very high-power systems.
- Lithium-ion batteries, which are mainly used in electric and hybrid vehicles because of their high energy density.
Of course, different types of car batteries have different storage capacity: z.B. 55 Ah, 60 Ah, 40 Ah, etc. The smaller the carriage, the less
ampere hour (ah) you need.
Trivia: interesting facts about car battery chargers
Can you use a used charger?
Normally, it is not a problem to buy and use a used charger. Of course, it may have a shorter life or weaker performance than a brand new unit.
But there are cases when you do not want or need to buy a new charger. If you want to use the charger only for a short time or in special cases, it is advisable to buy a used charger. That’s why we don’t care if it has a maximum useful life or power rating.
Always be informed about your car battery charger
It is advisable to always read the manufacturer’s warranty to avoid an unpleasant surprise if something goes wrong. In some cases, there can be misunderstandings that can waste money and time.
Therefore, you should read the manufacturer’s warranty and understand the refund conditions. This is important because different manufacturers issue different warranties. especially if you buy your charger on the internet.
