CTEK Chargers: Full Range Guide for 2025–2026

Why CTEK Is the Benchmark for Battery Charging

Founded in Sweden in 1997, CTEK has spent nearly three decades building a reputation that few competitors can match. The company now operates in over 70 countries and holds an estimated 20% share of the European premium consumer charger market. Those numbers tell a story, but the real authority signal is this: CTEK is the OEM-approved charger supplier for more than 50 vehicle manufacturers, including Ferrari, Porsche, BMW, Rolls Royce, Aston Martin, Jaguar, and Harley-Davidson.

That kind of manufacturer endorsement is not given lightly. When brands like these trust CTEK to protect their batteries during storage and transit, it speaks volumes about engineering quality.

CTEK holds over 210 active patents, with three new international patents granted in 2025 for its APTO Adaptive Charging Technology. The company reported revenues of SEK 914 million for FY2024, reflecting consistent growth in a global battery charger market projected to reach USD 44.9 billion by 2035.

The practical takeaway: intelligent chargers like CTEK's can extend battery life by up to 20–30%, according to industry data. A quality charger is a long-term investment that pays for itself by keeping batteries healthy for years longer than they would last without proper maintenance.

The CTEK MXS 5.0: Still the Crowd Favourite

The MXS 5.0 has been CTEK's best-selling model for years, and its reputation continues to hold strong. It was ranked #1 in Top Product Reviews' Top 6 Best Car Battery Chargers for 2025, praised for being fully automatic and reliable in all weather conditions.

At the heart of the MXS 5.0 is a patented 8-step charging process that goes well beyond simply pushing current into a battery. The sequence includes dedicated desulphation and reconditioning stages, which can recover deeply discharged batteries from as low as 2V. If you have ever returned to a car after months of sitting idle and found a completely flat battery, the MXS 5.0 is designed to handle exactly that scenario.

The charger supports batteries from 1.2Ah to 110Ah for ongoing maintenance and can directly charge batteries up to 160Ah. That range covers everything from a small motorcycle battery to a full-size car or leisure battery. It is fully automatic, so there is no need to adjust settings. Connect it, and the charger does the rest.

Being weather-resistant, the MXS 5.0 works well in outdoor storage situations or unheated garages, making it a year-round tool rather than something you only pull out in winter. At approximately £79.95, it represents strong value for a charger with OEM-grade engineering behind it.

One important limitation to be aware of: the MXS 5.0 does not natively support lithium (LiFePO4) batteries. If you are running lithium batteries in your vehicle, motorcycle, caravan, or mobility scooter, you will need the NXT 5 instead. This is the single biggest reason many MXS 5.0 owners are now upgrading.

CTEK NXT 5 and NXT 15: The Next Generation Has Arrived

The NXT 5 is CTEK's direct successor to the MXS 5.0, matching its 5A output but adding one critical capability: full LiFePO4 lithium battery support. This matters more than ever. LFP battery market share reached 44% in 2025, overtaking NMC chemistry for the first time, according to industry analysis. Lithium is no longer a niche choice; it is becoming the default for many applications.

The key technology upgrade in both the NXT 5 and NXT 15 is CTEK's APTO Adaptive Charging Technology. Rather than requiring you to select a charging mode manually (lead-acid, AGM, gel, lithium), APTO automatically identifies the battery's chemistry, size, and condition before charging begins. This removes one of the most common sources of user error with traditional chargers. Connect it, and the charger figures out the rest.

The practical difference between APTO and the older 8-step process used in the MXS 5.0 is straightforward. The 8-step process is optimised specifically for lead-acid batteries and follows a fixed sequence. APTO is fully adaptive and chemistry-agnostic, adjusting its charging profile in real time based on what it detects. It is a genuine generational leap in charging intelligence.

The NXT 15 steps up to 15A output, designed for larger applications: trucks, boats, caravans, and off-road vehicles. It features temperature-compensated, spark-free automatic operation, making it safe and effective across a wide range of conditions.

Both models were unveiled at SEMA 2025 as part of CTEK's biggest product refresh in years, alongside the CS ONE Gen 2 and the new RB booster range.

For motorcyclists, caravan owners, and mobility scooter users who have already switched to lithium chemistry (or are planning to), the NXT 5 is the recommended upgrade path from the MXS 5.0. Same 5A output, same compact form factor, but with the lithium compatibility you need.

CS ONE Gen 2: Smart Charging for the Connected Age

Launched in January 2026, the CS ONE Gen 2 is CTEK's most technologically advanced charger to date. It features built-in Wi-Fi and Bluetooth connectivity, paired with a fully redesigned CTEK App that lets you monitor and control charging remotely from your phone.

The user experience has been reduced to its absolute minimum. Polarity-free clamps mean you can attach the leads to either terminal without worrying about getting positive and negative the wrong way around. Combined with Connect & Forget functionality, this is the most user-friendly CTEK charger ever made. Attach it, walk away, and check progress from your phone whenever you like.

Under the hood, the CS ONE Gen 2 uses the same APTO Adaptive Charging Technology found in the NXT range. It automatically detects and optimises charging for any 12V battery type, including LiFePO4, with no manual input required.

This charger sits at the intersection of connected technology and vehicle maintenance. It is particularly relevant for fleet operators managing multiple vehicles, classic car owners who store vehicles for months at a time, and anyone with seasonal vehicles like caravans or boats left on charge over winter. The ability to check battery status remotely, without walking out to the garage or storage unit, is a genuine quality-of-life improvement.

We stock the CS ONE Gen 2 at hardwarexpress alongside the full CTEK range, with same-day dispatch available on most models for next-day delivery.

CTEK PRO25S: Built for Workshops and Trade Professionals

The PRO25S is where CTEK's engineering really flexes its muscles. This is a 25A professional-grade charger and power supply, compatible with all 12V battery types including LiFePO4. It carries a 4.7 out of 5 rating from 535 reviews on CTEK's own platform, which is exceptional for a professional tool at this price point.

The standout feature for workshop use is the dedicated SUPPLY mode. This provides stable power delivery for ECU programming and diagnostics without needing to disconnect the vehicle battery. Modern vehicles are packed with sensitive electronics, and voltage drops during programming can cause costly module failures. SUPPLY mode eliminates that risk entirely, making it a critical tool for any workshop handling software updates, key programming, or module replacements.

In terms of capacity, the PRO25S handles lead-acid batteries from 40Ah to 500Ah and LiFePO4 batteries from 30Ah to 450Ah. That range covers everything from passenger cars to commercial vehicles, vans, and agricultural equipment.

Temperature compensation operates across -20°C to +50°C, ensuring accurate charging regardless of workshop conditions. The PRO25S adjusts automatically for an unheated unit in January or a sweltering garage in August.

Automatic parallel load compensation is another practical feature. If electrical loads are running on the vehicle during charging (interior lights, diagnostic equipment, radio), the PRO25S adjusts its output to maintain consistent delivery without manual intervention.

OEM approval from 50+ manufacturers reinforces that this is a genuine professional tool, not a consumer charger repackaged for trade use. For garages, mobile mechanics, and fleet maintenance teams, the PRO25S is the right choice.

CTEK RB 3000 and RB 4000: CTEK Enters the Booster Market

For the first time in its history, CTEK has entered the jump-starter and booster category. The RB 3000 and RB 4000 were unveiled at SEMA 2025, marking a significant expansion beyond traditional charging products.

The numbers are impressive. The RB 4000 delivers 4,000A peak current with up to 45 starts per charge. The RB 3000 delivers 3,000A peak with up to 30 starts. Both are designed for professional and heavy-duty use, with enough power to start large diesel engines as well as standard petrol vehicles.

Both models feature spark-proof technology (a hallmark of CTEK's safety-first approach), USB-A and USB-C ports for charging phones and other devices, and multi-mode LED lighting for roadside use. These are practical additions that turn the boosters into genuinely useful emergency kits, not just single-purpose tools.

The smart approach is to pair these boosters with a CTEK charger. A booster gets you started immediately when you are stranded; a charger then properly recovers and maintains the battery afterwards, addressing the underlying issue rather than masking it. The two product categories complement each other directly.

As a relatively new product category for CTEK, the RB range is still underrepresented in reviews and comparison content. Early adopters are getting access to CTEK-quality engineering in a booster format before the wider market catches up.

CTEK vs NOCO: The 2V Advantage You Need to Know About

Both CTEK and NOCO are respected names in the premium charger segment, and both make good products. There is, however, one concrete technical difference that matters enormously for certain users.

CTEK chargers can detect and begin charging batteries from as low as 2V. NOCO's Genius series has a minimum threshold of 7V and will not recognise or charge batteries below that level.

Consider the real-world scenarios where this matters: a car left sitting on a driveway for several months; a caravan stored over winter without a maintenance charger connected; a mobility scooter unused since last summer. In all these cases, batteries can discharge well below 7V. With a CTEK charger, you have a strong chance of recovering that battery. With a NOCO, the charger may simply refuse to start.

This is not a minor specification footnote. For anyone who regularly deals with deeply discharged batteries, it is the difference between a recovered battery and a trip to buy a replacement. Given that a decent car battery costs £80 to £150 or more, the ability to recover rather than replace pays for the charger quickly.

Combined with CTEK's OEM endorsements from 50+ manufacturers and its broader range of professional and consumer models, CTEK holds a clear edge for users who need reliability across all discharge states. If your batteries are always kept topped up, either brand will serve you well. If deep discharge recovery is a realistic scenario for you, CTEK is the safer bet.

Which CTEK Charger Is Right for You?

With several models in the range, picking the right one comes down to your battery type, application, and budget. Here is a quick guide:

  • CTEK MXS 5.0 — Best for lead-acid car and motorcycle batteries on a budget. Proven, reliable, and excellent value at around £79.95. Not suitable for lithium batteries.
  • CTEK NXT 5 — The right choice for anyone with LiFePO4 lithium batteries, or planning to switch. Same 5A output as the MXS 5.0, with APTO technology and full lithium support.
  • CTEK NXT 15 — Designed for larger batteries in trucks, boats, caravans, and off-road vehicles. 15A output handles bigger capacities efficiently.
  • CTEK CS ONE Gen 2 — For tech-forward users who want app-based monitoring, remote control, and the simplest possible user experience. Ideal for long-term storage of classic cars, caravans, and seasonal vehicles.
  • CTEK PRO25S — Built for workshops, garages, and trade professionals. 25A output, SUPPLY mode for ECU programming, and compatibility with batteries up to 500Ah.

The lithium upgrade path: if you currently own an MXS 5.0 and have recently fitted a lithium battery to your motorcycle, caravan, or mobility scooter, the NXT 5 is the correct replacement. Same 5A output, same compact size, but with the LiFePO4 support the MXS 5.0 lacks.

Beyond cars and motorcycles, CTEK chargers are equally effective for mobility scooters, alarm system backup batteries, ride-on lawnmowers, and leisure batteries. Any 12V battery that sits unused for extended periods benefits from maintenance charging, and CTEK's temperature compensation features make every model in the range suitable for year-round use, from winter storage through summer heat.
