Auto charger for vehicles with Start&Stop function
Fast Start/Stop charging
The CT5 START/STOP battery charger and maintainer has been specially designed to charge and maintain batteries in Start/Stop vehicles.
Start/Stop technology is great for the environment but it can put a considerable strain on your battery, especially if it’s in an older car. By keeping the battery fully charged, you can take full advantage of all the Start/Stop technology benefits, such as better fuel efficiency and lower CO2 emissions. If you only make short journeys, use the CT5 START/STOP once a month to keep your battery in peak condition. And if you’re going away on holiday, just connect the charger to the battery to make sure your car’s ready to go when you return.
- Fully optimized for cars with Start/Stop technology, e.g. AGM and EFB batteries
- No buttons to press - fully automatic charging

Interesting video, but a word of warning with some modern cars it is very important not to fix the negative cable from the charger directly to the negative terminal on the car battery, due to sensitive equipment already attached close to this negative terminal, check in your car manual I think you will find it says never connect the charger negative cable directly to the battery terminal, it should then show were to connect the negative, this is usually were the main negative cable from the battery is bolted to the car bodywork, which is a little way from where the battery is situated.

Thanks for the info. I have found text in the manual that states that you should connect it to the earth point. moba.i.daimler.com/baix/cars/w205/en_GB/index.html#../../../cars/w205/en_GB/manual_s/subchapter_14_67.shtml:ID_727d8eb82a8ea48f351f19152ca6f244 states: *'Connect negative terminal of donor battery to earth point of your vehicle using the jump lead,'* I'll do this on my car and update the pinned message in here, also the video description to state the same 👍

You see me, I see you, you have a red cap in front of your battery, and just below that you have a black cap...no need to remove the entire cover....croc clamp onto those, direct to the battery is not recommended...merely a suggestion ...thanks for the video though.

please tell me, is led indicator always blinking red,yellow or green? I"m planning on buying either that or comfort panel, but having second thoughts which to get.. thanx

@TechboyUK 3 жыл бұрын

Yes, the LED always blinks, there is no timeout or on/off switch. I have it positioned so when I lift the bonnet, I can clearly see it. A good indication of a low battery is when the stop-start function doesn't work, even on long trips.

Hi - just a heads up the earth lead of the eyelet connection to the battery should go to a point on the bodywork not direct to the terminal, the vehicle has a battery management sensor on the neg clamp (the little black box on the neg terminal) If you connect where you have done it can cause issues (battery warning light)as you have by passed the sensor

@@tonyzeal6508 Hi Tony, thanks for the information. When I first got the charger I did hook it up to the dedicated point on the chassis, but when I explained it in a Mercedes forum, people told me that the advice had changed and that it's now recommended to use the negative battery terminal. I can't find any official recommendation on this on the Mercedes website, KZfaq, etc. Do you know where it is referenced? I will also e-mail Mercedes for clarification.

@surewin1668 3 жыл бұрын

Just wondering why you needed to open the battery cover and yet you can just slide the red positive cap and clamp it on and the negative can clamp on that copper bolt just slightly below ??

@TechboyUK 3 жыл бұрын

Positive - probably okay to do this, but it's easier to attach the eyelet to the battery terminal. Negative - I had it on the battery terminal for about 9 months without any issues, but following some other comments in here (and I've updated the video comments section), it appears that it is better to connect the negative to the chassis on the point that you mentioned 👍 I've done that and it has been fine.

I couldn't hear some of the dialogue towards the end so might have missed something. Can the Ctek be left in place and turned on to trickle charge semi permanently? Can you use the terminal under the red slide for charging as per Merc manual for jumpstart??

@TechboyUK 3 жыл бұрын

Sorry, it was a bit windy. I need an external microphone. Yes, the CTEK can be left in place to trickle-charge semi-permanently. After 8 days, it goes into a mode where the voltage goes up and down a bit, to keep the battery in an optimal state over a long period. I have had it on trickly charge for up to 6 weeks with no issues. I have been using the terminal under the red with no issues since last April, but people have commented here that you should actually trickle-charge with the point on the cars' chassis. On my car, there is a clearly indicated place for this. See moba.i.daimler.com/baix/cars/w205/en_GB/index.html#../../../cars/w205/en_GB/manual_s/subchapter_14_67.shtml:ID_727d8eb82a8ea48f351f19152ca6f244 states: 'Connect negative terminal of donor battery to earth point of your vehicle using the jump lead'. Please see the video description for more info on the parts I used, etc.

Nice car!! My battery in my gas w212 e350 went bad exactly 6 years from the date on the battery. I bought the ctek 7002 and it works great, I could not revive my old battery. I pried off the lids to each cell and one cell had almost no water in it, so that would be the problem. I do use the 7002 when I store the e350 in our garage. Were you able to save your battery or did you have to replace it? Thanks.

@TechboyUK 3 жыл бұрын

I've had the battery on regen-charge 3 times now and on charge for most of the last 6 months (I've hardly used the car as I'm working from home 100% since COVID). The battery is still bad, it doesn't hold its charge. At least the CTEK has meant I haven't had to replace the battery yet, as I just keep charging it.

Ctek a planned obsolescence ?

@TechboyUK 4 жыл бұрын

When I bought the CTEK, the UK lockdown rules meant that people could hardly use their cars. Even now with rules that are slightly more relaxed, we can drive as far as we want for pleasure. However, as I have the Mercedes and a Nissan Leaf, it's much more convenient to do short trips in the Nissan Leaf. I don't want to use my Mercedes (with an engine) for short trips because lots of short trips aren't good for it, the Nissan is electric. I've only used my Mercedes once (for a fun 30 minute drive) in 6 weeks! I don't know when I'll be using it again. For this reason, I'm glad I got the CTEK.

The ctek looks like a good charger. Don't think you needed the extra eyelets with the 3 leds, the ctek charger itself would give you the information.. or you could just buy a proper battery tester. I use the simple eyelets on my batteries as well. One thing.. You didn't show the ctek hook and if it was any use to you.

@TechboyUK 3 жыл бұрын

They eyelets with the 3 LED's aren't essential, just a 'nice to have' and didn't cost much. The charger comes with eyelets without LED's, so you can use these. You can always get the LED version later if you want it. The main reason I got the LED version is because I thought the batter of my 3 year old Mercedes was bad - they helped prove is it bad as it goes to red status in the LED's very quickly. They are just a quick guide and not very accurate, for an accurate reading you should test the batter with a voltmeter when the battery is cold (hasn't been used for an hour). You can see the hook at 10:07. Near the end of the video I mention that the hook isn't worth buying if you intend to wall-mount the CTEK (as I have), because the CTEK itself comes with 2 holes for wall-mounting. I hang the CTEK bag on it, containing the instruction manual and accessories (crocodile clips and the eyelet adapter). The hook acts as a bumper around the CTEK unit, so I would suggest getting one if you're ever going to have the CTEK on the floor at any time, where it might get scratched.

@@TechboyUK ..Ah..okay.. My mistake i thought that bracket you purchased in addition to the ctek one. I actually see it better at 6.44.. Looks nice... Just a suggestion, i wouldn't just use a multimeter to determine if you have a good battery. All the multimeter will show is if the voltage is low (i.e ., Battery is drained), which is what i suspect those 3 leds do. You can get a battery with a bad cell, or sulphated battery that can show a 12.7 voltage which looks like it's fully charged but fails under load because it can't provide the Amps. A good battery under a load test will drop from 12.7V to at most approx 10.5V. i had a battery that showed 12.9V but on load application dropped to 6V, and the longer the load the lower the V would drop.. it couldn't even run the air pump properly. It definitely wouldn't start a car. That's why i suggest a load tester or one that can measure the CCA. My battery was rated for about 650CCA..i suspect it might be about 200CCA or less now

@@mpcp27 Good info thanks, I might invest in a load tester later :-) The CTEK shows 8 different test/charging phases, but it doesn't give a detailed indication of the health of the battery.

@mpcp27 3 жыл бұрын

@@TechboyUK .. The one that can measure cca is supposedly the better one and puts less strain in the battery. If the battery is in poor condition, the load tester might tip it over the edge.. so i have read... But it's more expensive than the load tester... Just an fyi when you are ready.
