I used this in my mercedes c class 2013 and it did not work with the cigarette lighter attachment . Can you advise why?
I have plugged my traffic light adapter into a live cigarette socket, the battery is fully charged but the indicator only shows a red light
Will this work in a din socket? is it just a case of taking that red connector off? looking to use on my motorbike.
Can thsi be used with 12 volt lithium lifepo4 car starter batteries or is it only for lead-acid batteries?

Brilliant piece of equipment

Have a vehicle where the batteries are attached to the chassis and not easy to reach. Thought would a better option and it worked brilliantly.

Very handy just be sure you get one compatible with your charger

I ordered the wrong one for my charger first time round so be sure you get the right one ! Some only cover 7amp I need the 10amp version so had to return !

Excellent bit of kit

Good bit of kit to be clear the traffic light system, works well it’s a flashing LED light tho not a solid light just to be aware I had to google it to find that out.

I bought this as an add-on to my CTEC charger as an emergency fix, because the engine compartment (bonnet/hood) lid has an electronic catch. If the battery fails you can't get to it to charge it directly as the catch doesn't work! Having this gadget allows a re-charge from inside the car and avoids the trouble of having to "jump" the catch from an auxiliary battery. So, it does what I want. I don't find the indicator lights particularly useful in assessing the state of the battery in so far as they're over-pessimistic and don't really align with those on the CTEC charger. There's plenty of charge in the battery when they're flashing amber and still enough to start the car when flashing red. Following the lights would have you charging the car all the time. I don't particularly like charging the battery through the cig-lighter/power point as it's running through the fuse box. I normally use the CTEC accessory lead with eyelets at one end that you permanently connect to the battery and a CTEC connector trailing out of the battery box at the other to connect to the charger. This is very useful and saves having to remove the battery cover every time and simplifies things, assuming that the electronic bonnet catch will open in the first place!

Handy connector for trickle charge

In my Porsche I cant use the normal battery connections out of fear of damaging the car so read up and decided to use the internal passenger footwell charging socket instead. This was perfect for the job and reached perfectly as I already had the extension cable

Useful 12V socket to CTEK quick connect

This well-made connector gives a good indication of the state of charge of your vehicle battery with its traffic light type indicators and is a convenient quick connect to a CTEK charger.
