Fast & Efficient charging Conditions and recharges the battery in the shortest possible time Review: Reliable smart charger – easy to use and great for maintaining car batteries - I bought the CTEK MXS 5.0 to maintain the battery on a car that isn’t used daily, and so far it has been very reliable and straightforward to use. The charger is compact, well built and clearly designed for long-term battery care rather than just quick charging. The connection process is simple, with clear indicators showing each charging stage. It’s ideal if you want to keep a battery healthy over time, especially for vehicles that are parked for long periods. If only the cables were longer it would have been perfect. Overall, a well-designed charger. Not the cheapest option, but the quality and smart features make it worth it if you want to look after your battery properly. Review: Keeps batteries viable and extends life - I bought this charger as I have a camper van that spends several months a year off-road in the driveway, during the down season and I have both the van and leisure batteries to keep maintained. I had used a simpler trickle charger but The CTEK is specifically designed to restore and maintain batteries and displays exactly what it is doing in the charge cycle. It has done a great job of keeping those batteries maintained over the Winter and I also use it to top up the leisure battery before any trips away, especially where I am off-grid, as the inbuilt charger unit in the van cannot charge to the same high value. I had the battery in my car replaced last Summer and I was curious as to why the stop-start system was not working, similarly to before when the old battery was failing. I measured the voltage and it was low, so I used the CTEK to boost it up to full charge. The battery had clearly been stored at a lower voltage and never fully recovered until boosted this way. The battery has since been healthy and stop-start works perfectly. On the leisure battery I permanently wired up a CTEK cable to the terminals so I can just plug it directly to the charger while the battery is boxed up. I also got the 12v plug-in charger cable for directly plugging into the 12v auxiliary sockets in both the van and car. This charges the battery through any permanently live 12v socket, which is very convenient and saves raising the bonnet and using crocodile clips. Note that this only works on sockets that are always live and not those that only go live when the ignition is switched on. My experience is that this is a great charger for battery restoration, maintenance and boosting depleted batteries caused by short journeys or heavy use in winter. ## Features - Genuine Part ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00FC42HAA | | Amperage | 5 Amps | | Best Sellers Rank | 203 in Automotive ( See Top 100 in Automotive ) 1 in Car Battery Charging Units | | Brand | CTEK | | Brand Name | CTEK | | Colour | Black | | Compatible Devices | Vehicle batteries | | Connector Types | Crocodile Clamps, Ring-Terminals | | Country of Origin | China | | Current Rating | 110 Amps | | Customer Reviews | 4.8 out of 5 stars 9,605 Reviews | | EU Spare Part Availability Duration | 7 Years | | Global Trade Identification Number | 07350009569750 | | Input Voltage | 12 Volts | | Item Dimensions D x W x H | 14.4D x 27.2W x 5.4H centimetres | | Item Weight | 7.06 Ounces | | Item weight | 7.06 Ounces | | Manufacturer | CTEK | | Manufacturer Part Number | MXS 5.0 | | Model Number | 56-975 | | Output Voltage | 12 Volts (DC) | | Output voltage | 12 Volts (DC) | | Product dimensions | 14.4D x 27.2W x 5.4H centimetres | | Specification Met | Energy Star | | Specification met | Energy Star | | Unit Count | 1.0 count | ## Product Details - **Brand:** CTEK - **Colour:** Black - **Item weight:** 7.06 Ounces - **Output voltage:** 12 Volts (DC) - **Product dimensions:** 14.4D x 27.2W x 5.4H centimetres ## Images ![MXS 5.0 - Image 1](https://m.media-amazon.com/images/I/61cWffE5MQL.jpg) ![MXS 5.0 - Image 2](https://m.media-amazon.com/images/I/81RgEmyqs-L.jpg) ![MXS 5.0 - Image 3](https://m.media-amazon.com/images/I/71GXS3wXZcL.jpg) ![MXS 5.0 - Image 4](https://m.media-amazon.com/images/I/81iDSWTqTxL.jpg) ![MXS 5.0 - Image 5](https://m.media-amazon.com/images/I/714UJ3gHbGL.jpg) ## Questions & Answers **Q: Once switched on & mode selected, if there is a power cut, will the unit remember and continue automatically on the resumption of Mains power?** A: The charger remembers the Mode set with the button, but starts at the first step of the charging process for that Mode after a break in the power supply. **Q: How does this charger connect to the mains? I can't see a mains lead.** A: The cable on the left in the picture is about 2 metres long ending in a 3-pin 13A plug. That on the right ends in a mini line connector which mates with either the crocodile-clip or ring-terminal extensions shown (and included). A "cigarette lighter connector" (to charge through the 12V 'lighter' socket) is also available as is a rubber bumper. I bought these with the charger. My car's fuse panel can be configured to make the lighter socket permanently live so the charger can be left under the front passenger seat, invisibly topping up the charge when the car stands unused for days on end. The rubber bumper fits around the charger's plastic case, both protecting it against knocks and making it far less likely to slide off front wing, top of the engine or whatever. A brilliant bit of kit. Its 5A rating may look pretty modest but unlike simple chargers whose output drops sharply once the battery starts to take some charge, the CTEK pumps out a full 5A for the whole of the bulk charge phase; an overnight charge of a completely 'flat' will give you a fully (not partly) charged and reconditioned battery and it can be left connected for months if necessary. It's worth looking at the full specification on CTEK's own website. **Q: What is the mains voltage input range** A: 220 - 240v **Q: My son has just bought a 125cc motorbike. would the battery connectors on the CTEK charger be small enough to fit onto a bike battery?** A: Yes it will charge a car and bike. It has a dedicated bike mode which lowers the charging rate. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable smart charger – easy to use and great for maintaining car batteries *by D***O on 17 December 2025* I bought the CTEK MXS 5.0 to maintain the battery on a car that isn’t used daily, and so far it has been very reliable and straightforward to use.

Looked at the car's manufacturer’s charger, which is actually made by CTEK, and it was considerably more expensive. Decided to buy this one and it works perfectly with my car. If I now need to charge up the battery it is a simple matter of connecting two clamps and plug into the power. Simple, quality, compact charger which does the job with ease. ## Frequently Bought Together - CTEK MXS 5.0 Battery Charger with Automatic Temperature Compensation, Black - CTEK 56-304 Connect 2.5M Extension: extend the range of your charger - CTEK Cigarette Lighter Connector Adaptor 56-263 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/48102707-mxs-5-0](https://www.desertcart.co.uk/products/48102707-mxs-5-0) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-29*
