## Description

From the manufacturer You Have Chosen A Car With Start/Stop Technology START/STOP technology was invented to save both the environment and your wallet and is soon likely to be standard in the majority of European cars. When buying a new or almost new car, most people assume that everything will work without them having to do anything. However, for cars with Start/Stop technology that's not completely true. As soon as six months after purchase, you may notice that the engine doesn't stop as often as it should. Maintain Your Start/Stop Cars Benefical Functions Start/stop technology puts considerable strain on your car's battery. In order to maintain your start/stop car's beneficial functions, such as fuel efficiency and reduced environmental footprint, you have to take care of your car's battery. The CT5 start/stop battery charger is specifically designed to charge and maintain batteries in start/stop vehicles safely and easily. Avoid Expensive Battery Replacements And Extend Battery Life With the CT5 start/stop battery charger, you can avoid unexpected and costly replacements. When you only drive short distances, the battery does not have time to charge sufficiently, which reduces its life. Forgetting to turn off lights and accessories will discharge your battery over time and could leave you stranded. Safety, simplicity and flexibility characterises all products and solutions developed and sold by CTEK. CTEK supplies chargers to more than 70 countries throughout the world. CTEK is also a reliable OEM supplier to many of the world’s most prestigious car and motorcycle manufacturers.

Review: Top of the range charger - Bought this to firstly sort out my BMW start stop and second as a general charger. I’m writing this in March just as the winter comes to an end. My start stop hasn’t worked since October despite some journies of over 150 Miles. My usual run to work is 10 Miles each way. Not good for start stop technology especially in the winter. I tried a normal charger on my battery and found that it helped but after 24 hours with the Ctek it is sorted! Start stop works as it should. I plan to charge my battery once per month or every two weeks which is really easy with the Ctek. I have added comfort leads to the battery. Not the supplied ones but extra 10mm eyelet ones so they fit easily. Now the charger can live in the boot in the tool tray above the battery compartment permanently connected to the battery. As my car lives outside all I have to do is chuck an extension cable into the boot, connect up and I’m charging! The boot easily closes over the cable without damage. No worries about leaving it on too long either being a fully automatic charger. I also use this charger to top up my ride on mower battery over the winter and used the supplied comfort connector for this (6mm). These chargers are simple to use, have no fancy features or displays you don’t need they just work extremely well and hopefully should last based on the reviews. My understanding is the CT5 version differs from other popular Ctek chargers in that it does not go above 15v on a desulphation cycle as his can damage AGM batteries and at £200 plus for an AGM battery you don’t want to risk it! The Ctek CT5 should be an essential purchase if you have a stop start system and do not regularly do large mileage’s.

## Questions & Answers

**Q: How long is the power cable supplied with this battery charger?**
A: It's about 5 feet also the cables to the battery are quite long you can always use a extension lead I have been very pleased with this changer

**Q: what is watt rating of this charger? can this be run off inverter? what size (in watt) inverter is required?**
A: 3.8A.

**Q: Hi , can anyone advise if the stop / start model willl work on a pre 2015 diesel car ( 1.6 engine ) ?**
A: On the box it says "The CTEK START/STOP battery charger is specifically designed to charge and maintain batteries in Start/Stop vehicles safe and easy".  So, if your car has start/stop technology it will work on a diesel or petrol car battery.

**Q: How long roughly would it take for a full charge if the battery is depleted due to not having been driven for a month**
A: Best setting it on a reconditioning cycle, a slow charge too. This will probably take a good 12-16 hours. Just leave it to do it’s work ideally over a 24 period.

### ⭐⭐⭐⭐⭐ Perfect Charger For Stop/Start Car Batteries
*by M***N on 26 August 2025*

I purchased this Stop/Start charger after reading the positive reviews about it for stop/start batteries . My stop/start feature has not worked in months due to only doing short journeys most of the time each week so instead of replacing the EFB battery with a new batery, i bought this well know branded charger to fix my issues and i was not disappointed. Firstly it is so easy to use and connect to your positive and negative terminals before turning the power on but i connected the negative clamp to a bolt on my chassis for negative earth connection instead of the negative terminal which it says could cause a spark to fly and once you turn on the power , the charger will first check to see if you are connected properly and if not , the amber light will light up, telling you to try to connect it again properly. If the clamps are connected correctly to your terminals, the it will start to charge your battery and and finally when it is fully charged, it will light up green saying that it can be dis-connected from the mains power and dis-connect the clamps in the reverse order, negative first then positive. I tried it for the first time and it took about 3.5 hours before the green light appeared ,saying that it is fully charged but when i went to drive my car after it was charged up, the Stop/Start still didn"t work which was disappointing. I went for a long drive to see if that helped the voltage improve on the battery but to no avail so i left if for a week until i tried charging it again and this time it took 6 hours to charge the battery which was surprising but the following day, i drove my car and finally the Stop/Start worked again so this charger is definately the one to get if you have a stop/start car battery. It will save you alot of money replacing the older battery aswel.
