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: Call this thing a necromancer, it resurrects the dead! - I've tried simpler 'smart' chargers that would often be connected to a flat battery and refuse to do anything - voltage too low. This CTEK one was purchased because I swap between two cars - one for summer, one for winter, cheaper than running both at once - and the inactive car's battery often needs some assistance when switching over. The 'recondition mode' has already brought 2 batteries back to useful capacity despite being below 10v. I've just given it its biggest challenge - a good-quality Bosch battery that was registering less than 6 volts due to constant drain. The MXS5.0 didn't give up, and after a 12-hour charge, reported it as green. Sure enough, it's holding a steady voltage. Whether the battery will actually start the car after being so badly drained remains to be seen, but I'm very impressed that the charger managed to bring it back to 12 volts. It's paid for itself already, being cheaper than a battery for either of my cars and has saved me replacing both. It's worth noting that both cars have good-quality batteries fitted that are also worth the extra money over cheaper ones, as they can take quite some abuse and be brought back. Its ability to restore a cheaper battery may vary due to the more rugged design used in high-end batteries. The user interface is very simple, just push the Mode button until the LEDs point to the combination you want (motorcycle or car capacity, Absorbent Glass Mat technology, Recondition mode) and let it do its thing. If it's unplugged, it'll resume the same settings on next connection. I think the 5.0 is worth the extra over the 3.8 as it charges faster. The cables, clips and connectors are all good quality, and I bought an extension lead for the 12v end so I can leave the battery in a well-vented area while keeping the expensive charger under cover. The included bag is big enough to fit the charger, manual and extra extension lead in one neat package. When the battery finishes charging, the charger automatically drops to a maintenance mode, monitoring the battery voltage, and will start charging again if the voltage begins to drop. This keeps lead-acid batteries in good condition - the chemistry works well with a small, but constant, amount of power flowing through the cells. In short, this is a brilliant charger to keep handy if you have a car that is seldom used. It may save you replacing the battery many times over. An edit: This charger is still working perfectly in 2025 and has never let me down. It's just resurrected a pair of batteries that were standing for many months and were reading less than 3V total. It took a boost from a solar panel to 'kick start' the charge cycle by bringing the voltage up, but once they were reading 10V, a lengthy charge and recondition cycle followed which has restored both batteries to >90% State of Health according to a battery tester. I've done similar for other batteries, bringing them back from extremely low voltages and coaxing additional life out of them, enough to start the engine and get going. It's not perfect and there will be some capacity loss, but this charger has paid for itself many times over in not needing to replace dead batteries so often. I've lent it to colleagues to run cycles on their cars. The cables are wearing well and the Comfort Connect clips are still holding strong. I also realised that the charger body is IP65-rated waterproof, so can be left outside in the rain safely while charging. This has much simplified charging my cars. Overall, this is exceptional quality and value for money. It has paid for itself many times over in replacement car batteries! I've never had to talk to CTEK support as I've never had a problem with my unit, it's been entirely reliable and dependable. Thoroughly recommended.

## 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.

### ⭐⭐⭐⭐⭐ Excellent charger
*by P***H on 7 April 2021*

Like many, I've found that my car is sitting idle much longer at the moment and during the cold months the battery would run down to the point where the engine wouldn't fire. It was a combination of few short journeys but with lights and wipers on, cold starts in freezing weather, and the slow drain that occurs in modern cars that have security systems running when the car is unused. I had an old style and rather clunky charger bought in the 1990s but it didn't seem to make a long-term difference to the state of the battery. I got to the point of thinking I needed a new battery but then read up about ways to restore a battery and the CTEK chargers were recommended by users on various websites. This device isn't the cheapest in the range but is cheaper than a new battery, and since I figured I'd probably need a charger whatever I do I decided to get this and see if it made a difference before getting a replacement. There isn't a great deal to understand about the unit - just follow the instructions and set to the appropriate requirement you have, ie, small or larger battery etc. Then leave it to run. The indicator lights show where you are in the charging progression. At the end the status lights show if the battery was usefully charged or whether your battery is needing replacement. Happily, mine charged successfully and the difference was noticeable. The interior lights were brighter and the car started easily. I added the supplied detachable lead to the battery so that reconnection is easy but you can just connect with the supplied crocodile clips. All the parts seem well made and instructions are clear. Recommended.
