## Description

Specially designed for start-stop vehicles, this intelligent charger maximizes battery life and ensures reliable performance. Fully automatic with 5-year warranty.

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.
Review: Brilliant and so easy to use. - I'm so pleased I read that you should use a 'Stop Start' charger on Stop Start batteries. Evidently the initial ' charge surge' from a conventional charger can be detrimental to a 'Stop Start' battery. I had been going to use my reliable 12 years old CTEK charger but checked as my car has this Stop/Start feature and this had failed to operate every time it should. I guessed it was due to the short journeys we do and the general lack of overall use as we only do around 1000 miles a year now-a-days. This charger fits the bill perfectly as it's specifically designed for Stop Start batteries and is extremely easy to use. Hopefully it will last as long as my older CTEK charger has. Shame it doesn't come with a storage bag as well though.

## 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.
