CTEK makes a bunch of different connection accessories. On the Viper I have them hard-wired to the battery with a plug that drops down in the rear so I just have to reach under and plug the charger in. They do cig lighter adapters as well, and a whole bunch of extensions, etc. https://www.amazon.com/CTEK-56-263-Comfort-Connect-Plug/dp/B0016LA5O8

Fancy... but don't our cars come with standard flooded/sealed batteries?

Come to think of it, my other car runs AGM battery from the factory, but I'm running the Battery Tender JR with no issue.. it is the most current model which may/may not matter.

I got this one and it works on all types of batteries.

AGM batteries are very sensitive to temperature, so chargers that are rated to handle AGM are able to compensate (lower current when hot, more when cold). If you're in a non-extreme climate, not having this feature might not matter. If you're someplace like Arizona as I am - it very likely does.

I just double checked and the JR also supports AGM. (it's under the Additional Information menu).

Now the 'maintenance free' batteries I was referring to in the above post are the standard acid batteries where I would add water even if they are called 'maintenance free'.
No to my knowledge. Just have to be a 12v cig plug that is still powered on when the ignition is off.

I tried using the 12V cig plug on the console with my CTEK and it does not work. It is not powered with the key off and out of the ignition. Does anyone know if there is a work around to be able to provide power to the cig plug? Seems I have seen something about changing or adding a fuse or ...? I will connect directly to the battery when it becomes necessary but would like to be able to use the cig plug if at all possible.

It must have a bad connection or blown fuse now because it should be working. I use mine in my 18 GTI daily and have since day one. It's powered with the key on by the way.

It works with the key on but I want to use it to charge/maintain the battery when the key is "off"/removed it isn't powered. I am asking if there is a way to have it powered with the key out so I can charge the battery using the cig plug say over the weekend when I'm not using the car.

I use a Noco 1 for my boat's batteries. It's a maintainer so can be left plugged in. I've noticed that once batteries are fully charged they do not really discharge much (ever after 2-3 months).

Every quarter or so I plug the Noco into my cars. It always takes a surprising amount of time to 'top off' the batteries.
