I have a DieHard 200.71219 2-amp battery charger/maintainer I once used on my motorcycle. I sold the m/c and now want to use it on my '08 C-6 since it's winter and I'm just not driving the car very much.
The charger has a lead with circular terminals on the ends and it has an inline disconnect. I'm considering connecting these terminals to the battery posts by screwing them on top of the existing battery studs but not sure if this stud is a common size; loosened one of the nuts and noticed that it's a self-locking. I don't know much about these newer style battery cable connectors on the C-6, and I'd rather not try to put the terminals under the battery post tightening nut. Is this the proper location for hooking it up?
If you don't have one, you should be able to purchase a cigarette-lighter adapter for the maintainer. Here is an example of one, and you can check the pic to see if the cable on your existing maintainer would be compatible with the connector. The socket in the console is live all the time, so what a lot of us do is to plug the maintainer into that outlet, and then run the cable out at the bottom of the door. There is a natural groove in the bottom of the door sill so that the cable doesn't get pinched. I leave mine plugged in whenever it's in the garage.

Reason: changed glove box to console
I don't know why folks insist on making battery tenders so complicated.... the small stud on top of the battery is a 6mm. Don't unscrew the existing lock nuts, just slide the loops of your existing battery tender over the stud and on top of the lock nut, and then screw a 6mm nut down on top. It works perfectly and the only additional item you will need to make it work is two 6mm nuts.

That's what I do too. Use a battery tender extension, take up slack with cable tie. Run end through grill and loop back about 6". Just need to flip it out to connect. Easy
Wondering why you prefer this to direct connect to battery?
Easy to do and it’s out of the way of the battery, and takes no longer to install this way

What I posted above is just as easy and is out of the way of the battery not complicated

That's the only way to do it, then you never have to open the hood to hook up tender. Very

Set up my ‘08 like this ^^^ when I bought new and continue to this day. Connect it however makes sense to you and meets your needs for parking, convenience, etc. important item is to use the tender when not using the car.
Here’s a pic of the magnetic connector in the front grill when you back out of the garage if comes off, when you get home you pop it on no hood to open no running to your center console and under the door. This is by far the easiest best way to add a maintainer. Connect the wiring as I showed in pic above
