CTEK (MXS 5.0)
A General Purpose Charger for Any Battery
While jump starters are considered universal devices for starting petrol engines quickly, nothing can really compare to the versatility of stationary models. But how do you pick the one that can work with various types of engines? Fortunately, this model from CTEK is, perhaps, the most versatile of them all.
First things first, the stationary car battery chargers don’t have a built-in battery, and the MXS 5.0 is not an exception to the rule. While its design takes the portability aspect out of the question, that’s where the fun begins.
The package includes a set of different clamps that can accommodate virtually any vehicle that runs on fuel, including car, truck, and motorcycle batteries. The first set of clamps are your regular car battery clamps that connect to the standard 12 V Lead-Acid models. The other two, however, are more suitable for smaller battery variants, including those with two-pins terminals, and smaller, battery terminal connectors.
While portable models need to be charged in advance, the stationary ones can work straight away as soon as you plug them into a power socket. The only thing you absolutely need to do, though, is to pick a required charging mode before you connect the clamps to a battery. Once set, the device will charge the battery in a matter of hours, or, alternatively, will allow jump-starting your vehicle in under a couple of minutes.
Protecting Your Battery With Ease
As for other convenience features and quality-of-life improvements, using this model from CTEK allows prolonging the service life of the battery up to 3 times, which is not a small feat, considering how fast some batteries can become inoperable using simple charging adapters.
Alternatively, more accessories from CTEK are optionally available, so, if you want to purchase a protective bumper or a longer power cord, you can ensure that the device will work flawlessly by ordering one.
Last but not least, unlike many other models widely available on the market, the MXS 5.0 comes with an impressive, 5-year warranty on all components listed in the kit, which is a big plus in our book.
All in all, using a stationary jump starter is a perfect way to charge flat batteries of your vehicle in case you don’t have an adapter in your garage. However, if you own more than one vehicle with different batteries, this model from CTEK will be an excellent product to consider. Simple and easy to use and maintain, it is a cost-efficient charger that will not only allow you to start your vehicle but also won’t harm the power cells of the battery itself.

If your vehicle is fitted with a lead-acid battery, the type of charger you need should be something like the Sakura SS3630 6A, a car battery charger specially designed for charging said batteries. Lead-acid batteries use a special charging algorithm known as constant CC/CV (current/constant voltage). The constant current of the charge influences the battery gradually increasing the voltage. When this voltage reaches a certain value, the charging current goes down to the saturation level. The total charging time on average makes 12-16 hours for conventional batteries and 36-48 for special industrial heavy-duty models. The lead-acid electrochemical system is rather slow and can not be charged as quickly as others.
Charging the lead-acid battery should consist of three stages:
- the mode of charge maintenance.
The DC charge delivers most of the energy and takes about half the time from the entire charging process; the saturation charge uses lower current and is necessary to achieve the full charge, and the maintenance mode compensates the losses caused by self-discharge.
Simple and Affordable
With the Sakura SS3630 6A Battery Charger, you won't need to worry about leaving a radio on for the whole night. Even if you wake up and find out that the battery of your car is dead, you won't have a problem to bring it back to life in mere minutes. The Sakura SS3630 6A is suitable for all vehicles with engine capacity 1.8 litres or less, which covers a good range. It comes fitted with alligator clips and works from the mains.
All things considered, you can seriously consider purchasing the Sakura SS3630 6A Battery Charger should you need a charger for lead-acid batteries. It's budget-friendly, small in size and very convenient in terms of storage and transportation. Keeping this charger handy, you'll never end up with a flat battery on the road.

What Is a Car Battery Charger?
A modern person is surrounded by a lot of different machines that work on batteries. This is a mobile phone, a laptop, an electric tool, a flashlight, various vehicles and, of course, a car. We cannot imagine our life today without cars. They are everywhere. Long gone are the days when a car was regarded as something of a luxury, in present days cars have become one of the more convenient ways to commute around the city as well as travel on long trips. The only inconvenience driving a car entails is maintaining its battery, which means a driver should always carry a special car battery charger along with him no matter where he goes. A car battery charger is a small device which usually works off a power socket to supply the connected battery with electricity. These chargers come in various capacities and can be used to charge a battery not only of a car but also of a boat, snowmobile, lawnmower and other vehicles and tools that use power.
To maintain the engine of your vehicle in a good condition, it is important that you feed it with high-quality motor oil. Also, you may want to get a special car vacuum cleaner to tidy up the interior of your vehicle and clean it off all dirt that might have stuck between the seats and upholstery. While applying a little bit of wax to the outer of the car will let you make it shine anew.
What Features to Compare
Selecting the right battery charger for a car, motorbike or a boat, first of all, check whether the device is compatible with the model you chose. Basically, each car battery has its rated capacity specified in Amp-hours (Ah), while chargers usually provide the value of the charging current or output amperage they deliver (A). If you want your device to charge the battery faster, you need to consider the models with a higher output current rate. However, it's equally important to know the voltage of the battery of your vehicle. Passenger vehicles and motorcycles are typically equipped with 6V and 12V batteries, while 24V batteries are commonly used on trucks and other transport devices with diesel engines.
There are other important points to consider when choosing a vehicle battery charger. For example, extra connectors included in supply packages of some charging devices of this type provide more flexibility of use and simplify their connection to different battery posts. Some chargers come with built-in LED indicators that show battery charge status and provide information about the current device operating mode.
As you have already known, it's very important to take safety precautions when working with electricity, and using a car battery charger is not an exception. To ensure user's safety of use, some chargers come equipped with crucial safety features such as protection from reverse polarity connection, overcharging, short circuit. As for protection measures, many of them may come integrated into the charger body, thus we recommend considering it carefully. The best options offer all the listed protection features.
Did you know?
What Influences a Car Battery Life
Such a complex mechanism and component of a car as a battery has several important factors which affect its overall performance. To understand how to maintain the battery, you need to consider each factor separately:
- Level of charge. It is an important factor which directly influences the long-term work. To increase it, try to keep the level of charge as high as possible. Watch for the level of charge. Do not ignore network charging.
- Work temperature. Its degree impacts the starting capacity of a battery. When exposed to cold temperatures on a discharged battery, electrolytes can simply freeze. In summer, it can lead to evaporation of the liquid from the electrolyte.
- Car electronics. This is probably the most important factor out of all. A faulty generator supplying too high voltage can destroy the battery and is likely to "overboil". Excessive charging also destroys the structure of the electrodes inside the battery.
- Corrosion and sulfation. No one is insured against these. Corrosion and sulfation come in the result of constant work and is a natural consequence of frequent exploitation. However, if you use distilled water when servicing the battery, you will be able to prevent the early corrosion appearance and prolong the battery service life on the whole.
Some Interesting Facts
- The battery is a chemical source of current. Accordingly, the Arrhenius equation on the effect of temperature on the rate of reaction works here. In winter, the battery absorbs and gives off charge worse.
- "Super-modern" AGM and gel batteries were invented in the 20s of last century. Surprised?
- Modern batteries really serve much less time than their predecessors did 25 years ago. However, new batteries have much higher current characteristics.
- In winter, even a new charged battery on a regularly used car can get low. At low temperatures, the battery takes charge worse than in warm season. For this reason, a working battery in winter can easily lose the charge, especially if a car is used for short trips around the city when the engine rotational rate does not exceed 3,000.
- In winter, the battery should be periodically removed from the car and charged after being warmed in the air to a certain temperature. Warming a cold battery in hot water is not recommended: because of the rapid temperature changes, the active mass of the plates may shed.
- The parking lights are the most dangerous for the battery. They do not turn off after pulling out the key and keep on consuming energy until the complete battery "exhaustion". A few hours is enough even for a new German battery to lose its charge in the cold.
- Absolutely dead battery once on a frosty Monday morning - that's often the reason for the collapse of so many brilliant careers. So what do you do? Do not hesitate to charge it! When properly charged, in most cases, it is restored to its original state. Thus, the battery comes to life and continues working.
- Do not replace the battery while the engine is running. Disconnecting and connecting the battery causes voltage fluctuations, which can provoke malfunctions in the electrical equipment of your car.
- Chargers powered by an electrical network are the fastest and easiest to use: the battery can be put on charge at the programmed time.
Q: Does the size of a car battery charger matter?
A: Yes, it does. Using a smaller battery charger than recommended typically takes longer to charge the battery to the same level. However, if you are planning to use the charger only for the maintenance, it will handle this task quite easily. A car battery charger with higher output current will charge batteries quicker but may shorten their lifetime.
Q: Is it important to ensure correct charging voltage?
A: Basically, the value of float and high rate voltages is determined and specified by the battery manufacturer. It depends on two factors: battery chemistry and its build. Deviating from the recommended values will naturally result in the battery undercharge or overcharge, and therefore reduce the battery’s lifetime and performance.
Q: What is a maintenance mode of a battery charger/maintainer?
A: In a maintenance mode, the charger/maintainer keeps the full battery charge at the same level by supplying the current in small portions when necessary. Typically, if the actual battery voltage drops below a certain preset level, the unit switches to the charging mode and performs the charging until the battery voltage returns to the full charge level. Then the appliance switches back to the maintenance mode. Usually, chargers switch between these modes automatically.
Q: How long can I leave a charger connected to the battery?
A: It actually depends on the type of a vehicle battery charger you use. Typically, a battery charger should be left connected to a battery until the battery is fully charged. If you're planning to utilise a manual charger, it should be disconnected as soon as the battery charge level has reached its full. The point is that such chargers do not shut down by themselves and continue to supply electricity to the battery even in case the battery has got already charged. Automatic chargers, in turn, usually ensure optimal charging mode and prevent overcharging of the battery. Automatic chargers don't change operational parameters of a battery to such a large extent as manual chargers, however, they are also not designed for an uninterrupted use with batteries. Therefore, it's reasonable and safer to disconnect car battery chargers from the battery after the charging is complete.
Q: What is a microprocessor-controlled smart battery charger?
A: A microprocessor-controlled battery charger is a device which controls all aspects of a battery charging to increase the charging rate and lifetime of the battery. Basically, these chargers collect all necessary information from the battery and adjust the charging current and voltage based on this information. This approach enables the charger to charge your battery quickly, and completely. In addition, a fast intelligent charging doesn't affect working parameters of the battery and its lifetime.
