" Review: Good quality charger and conditioner - I don't write many reviews on desertcart but having recently used it in anger I thought I'd add my thoughts on this charger. I've had my CTEK MXS 3.8 for 6 years so this is a long term review. I bought it for my 1961 Hillman Minx, which used to eat batteries as it is laid up every winter, doesn't do a huge amount of mileage in the summer and isn't terribly efficient at charging when its running, so I used regularly to have recourse to an old-school non-smart charger. I was recommended the CTEK by a mechanic I know who specializes in restoring high end classic cars and keeps several himself. Since purchasing the CTEK I leave the car on charge in the garage full time (the eyelet lead allowing a permanently available plug-in connection is great), relying on the charger to keep the battery charged and conditioned. The result is that my old car is always ready to go, and I have only just needed to replace the battery which I'd then had about a year, so it was 7 years old altogether - previously they generally lasted about 3 years before they became incapable of holding a charge. However just this week I've put the charger to another use which prompted this review. My daily driver is a Toyota Prius, and anybody familiar with these cars knows they have a low powered 12V auxiliary battery that is only used for initially booting up the computers and enabling the main traction batteries. Unwisely I left the car unused for a few weeks during Covid lockdown resulting in the 12V battery going flat. Priuses have a lot of sensitive electronics and it's easy to cause problems if you're not careful when charging them but the CTEK did the job without fuss and showed 4 LEDs (ready to start) in just a few hours. I can't speak to the mode switch that some reviewers have complained about as I set it to normal when I first got it and haven't touched it since. I don't have a motorbike and the cold weather setting merely increases the charging voltage from 14.4V to 14.7V according to CTEK. I'm not sure how much benefit there is to that, it certainly seems to function perfectly well when left in normal mode. I can confirm that the charger still works as well now as it did 6 years ago ,having been in almost continuous use, and it has already more than paid me back its purchase price by extending the life of my battery. Review: Penny For Penny - Pound For Pound - CTek make the best trickle Chargers - I've got three of these chargers - one each on two motorbikes and one on the car. They have been in constant use for the past three years. The idiot proof lights are great when you just need a quick glance to see everything is working okay. They are 'a must' if your vehicle is parked outside or in a very cold garage. I made a very long extension with the cable going to the vehicle and the charger inside the house. One of my batteries is well past it us useful life time but keeping it on trickle has given it a few more years. Th weather tis winter has been a good test for any trickle charger and CTek never fail. Note: If you switch the unit off, make sure you remove the connectors from the battery or else it will discharge the battery albeit by not very much. ## Features - Charges all types of 12v lead acid batteries wet, MF, GEL, Ca/Ca and AGM - Comfort Connect compatible - Battery capacity: 1.2Ah to 80Ah - Charger type: 7 stage, fully automatic charge cycle ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00E5VS58Y | | Amperage | 0.8 Amps | | Best Sellers Rank | 7,933 in Automotive ( See Top 100 in Automotive ) 75 in Car Battery Charging Units | | Brand | CTEK | | Brand Name | CTEK | | Colour | Black, Red, Silver | | Compatible Devices | Vehicles with 12V lead-acid batteries, such as cars, motorcycles and other vehicles. | | Connector Types | Crocodile Clamps, Ring-Terminals | | Country of Origin | China | | Current Rating | 3800 Milliamps | | Customer Reviews | 4.7 out of 5 stars 968 Reviews | | Global Trade Identification Number | 07350009569729 | | Input Voltage | 240 Volts | | Item Dimensions D x W x H | 6.5D x 16.8W x 3.8H centimetres | | Item Weight | 0.7 Kilograms | | Item weight | 0.7 Kilograms | | Manufacturer | CTEK | | Manufacturer Part Number | 56-964 | | Model Number | 56-972 | | Number of Ports | 1 | | Output Voltage | 14.4 Volts (DC) | | Output voltage | 14.4 Volts (DC) | | Product Warranty | 5 Years | | Product dimensions | 6.5D x 16.8W x 3.8H centimetres | | Specification Met | Energy Star | | Specification met | Energy Star | | Unit Count | 1.0 count | ## Product Details - **Brand:** CTEK - **Colour:** Black, Red, Silver - **Item weight:** 0.7 Kilograms - **Output voltage:** 14.4 Volts (DC) - **Product dimensions:** 6.5D x 16.8W x 3.8H centimetres ## Images ![MXS 3.8 Multi Functional 7-stage battery charger 3.8 A - Image 1](https://m.media-amazon.com/images/I/71tto333ieL.jpg) ![MXS 3.8 Multi Functional 7-stage battery charger 3.8 A - Image 2](https://m.media-amazon.com/images/I/719FuQWydeL.jpg) ![MXS 3.8 Multi Functional 7-stage battery charger 3.8 A - Image 3](https://m.media-amazon.com/images/I/71w2J7MFX8L.jpg) ![MXS 3.8 Multi Functional 7-stage battery charger 3.8 A - Image 4](https://m.media-amazon.com/images/I/81NtGllrcBL.jpg) ![MXS 3.8 Multi Functional 7-stage battery charger 3.8 A - Image 5](https://m.media-amazon.com/images/I/71fASTdullL.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 ### ⭐⭐⭐⭐⭐ Good quality charger and conditioner *by D***R on 20 November 2020* I don't write many reviews on Amazon but having recently used it in anger I thought I'd add my thoughts on this charger.

I had a two year old battery in my car and during the Covid lockdown, I was unable to use my car. The battery lost three cells and I had to buy a new battery. That's when my Neighbour suggested one of these chargers. They are nice and small and fit easily under the closed and locked bonnet for constant charging. The first problem I encountered with this unit is the size of the ring connectors for permanent connection to the battery. I believe that they are 6mm rings and I had to purchase another connection cable with larger ring connectors. As this also works for motorcycles, I guess the 6mm ring size is perfect for one of those batteries. Another minor issue is the LED display. The first five LED's are nice and bright yellow, but the last two area very feint green which I could not see in daylight. Having said that, I would recommend this charger if you do not intend to use your vehicle very much as it can been left charging as long as necessary. ## Frequently Bought Together - CTEK MXS 3.8 Multi Functional 7-stage battery charger 3.8 A - CTEK 56 - 304 Connect 2.5M Extension extend the range of your charger - Ctek Cigarette Lighter Connector Adaptor 56-263, Black/red --- ## 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.kr/products/48806429-mxs-3-8-multi-functional-7-stage-battery-charger-3](https://www.desertcart.kr/products/48806429-mxs-3-8-multi-functional-7-stage-battery-charger-3) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-06-19*
