CTEK was one of the first companies to introduce “smart” battery chargers and they are now the market leader in high-quality chargers all over the world

 As well as 240V chargers, CTEK also design and produce a range of integrated solutions Integrated solutions, chargers which are built into vehicles and these include battery-to-battery chargers such as the DUAL D250SE and the Smartpass.

Vanhomes are pleased to be able to supply these products to motorhome and campervan enthusiasts and converters. For information on buying CTEK products for your business please get in touch


Car batteries

There are many different types of car battery available today, including wet cell, calcium and Absorbed Glass Mat (AGM) . Each needs to be maintained in a slightly different way, but all of them can be charged and maintained with a CTEK 24V or 12V battery charger.

For car batteries, a 12V battery charger such as the MXS 5.0 will charge and condition the battery through a series of stages. First it removes the sulphur from the internal plates, then breaks it down and mixes it back into the acid solution to give the battery a new lease of life. For trucks and other larger vehicles, CTEK’s 24V battery chargers will perform the same task.

Wet cell, calcium and AGM are all different versions of the lead-acid battery, and have their own advantages, disadvantages and maintenance requirements.

Wet cell car batteries, or flooded batteries as they’re also known, still dominate a large part of the car battery market. The first wet cells were typically fragile glass containers with lead rods hanging from an open top. Now, developments in manufacturing techniques and safety have seen the wet cell progress to an affordable, reliable and – if recharged and maintained correctly – long lasting vehicle battery.

Calcium batteries are also a big part of the battery market and have the same generic make up of wet cell batteries, except both the positive and negative plates are replaced by calcium alloy. This means that fluid loss is about 80% lower than a normal wet cell battery and the self discharge rate is also considerably lower, so there are huge advantages to these units.

AGM – or ‘dry’ batteries – are the latest step in the evolution of lead-acid batteries. Instead of using water or a gel, an AGM uses a fibreglass separator to hold the electrolyte in place.

Gel batteries use a gelified acid. Gel batteries can withstand deep discharging and are generally used in vehicles with demanding electrical equipment, electric wheelchairs and on boats.

All of these batteries use different technologies to suit the different needs of the vehicle. But they all have one thing in common – they need to be carefully maintained to ensure they always provide the energy needed. None of them are free from self discharge so they’ll all require a charge at some point and a CTEK 24V or 12V battery charger will see to that.

Unlike many battery chargers on the market, a CTEK 24V or 12V battery charger will react only to a battery’s specific needs, so every CTEK charger will charge, condition and prolong the life of all types of car battery.


Smart battery charger

CTEK designs and manufactures a range of smart battery chargers and accessories to suit all types of lead-acid batteries for vehicles including cars, bikes, marine vessels, agricultural vehicles and even lawnmowers.

All of our smart chargers are fully automatic, spark proof and reverse polarity protected, and you don’t need any special knowledge to use them. Our patented pulse maintenance technology also means that our chargers can be connected to the battery for months at a time, so you can simply connect and forget.

A CTEK smart battery charger goes through a series of stages during the charging process to desulphate, revive, charge, condition and maintain all types of lead-acid batteries. This prolongs their life and saves you time and money.

Our smart chargers constantly communicate with the battery throughout the whole process and they only supply charge depending on the battery’s exact needs. This prevents over- or undercharging, which can reduce the battery’s lifespan.

Each CTEK smart battery charger also regulates the mains voltage to protect any sensitive electrical and hi-fi equipment.


Car battery charger

Finding the right car battery charger for you
A car battery charger shouldn´t just be taking up space in your garage or only used when your vehicle won´t start. Your battery should be cared for like any other part of your car and using the right battery charger can help you do this.

All batteries need charging from time to time and CTEK´s wide range of chargers are suitable for conditioning, charging and maintaining all types of lead-acid batteries. A 12V car battery charger is likely to meet your needs and there are quite a few to choose from.

A smart car battery charger doesn’t just charge, it also performs other functions, such as reconditioning to prolong the life of the battery and keep it in optimum condition. A CTEK smart battery charger will give your battery a new lease of life, for example if sulphur has built up on the plates inside the battery, or if it’s suffering from discharge because of infrequent or short journey use,

MXS 3.8 – One of CTEK´s entry level models, it provides all round charging through a 7-step charging cycle that includes a desulphation feature and maintenance charging.
MXS 5.0 – A state-of-the-art 8-step charger with a special reconditioning function. It also features battery diagnosis so you know the state of your battery’s charge and whether it can hold its charge properly. As with all CTEK chargers, it has an optimised charging mode for when more power is needed during cold weather.
MXS 7.0 – A great universal charger with slightly more power, including a battery capacity of 14-150Ah up to 225Ah for maintenance. This is an 8-step charger with a power supply mode so the battery can be disconnected without losing or damaging the vehicle’s important electronic configurations.
These are just three of CTEK´s smart battery chargers.

Our chargers don´t need any specialist knowledge and they can be safely left connected for long periods of time – even months – as they keep your battery maintained.

And because they’re fully automatic, reverse polarity protected and spark proof, we can guarantee you peace of mind whichever CTEK car battery charger you choose.
