Which battery tender?
I know there's a few different types out there, from smaller than a cell phone to the size of a normal battery charger. Any particular one you've used and prefer?

I have stuck with the Battery Tender. Brand. They are not expensive and they are reliable. My oldest is decades old and still works fine.
Just watch if you go to a no brand or mystery model as that may be a risk to fire. Many cheap no name tenders have been fire hazards.

I use Noco Genius one for my C5, liked it so much bought a 2nd for my 1965 Chevy C10 truck.
Just bought another brand off Amazon for motorcycle batttery called Motopower Jr 800, it seems good as well but the display is smaller so I go up closer to see it’s in green.
I like the motopower Junior because I can leave the ring terminals on the motorcycle and unplug the harness, then plug the other harness on that has clamps to use on another car.
It’s on sale for $13.99 at the moment, I paid more.

I used the Deltran Battery Tender Plus for many years and never had a problem with it. CTEK makes a good tender too.

I'll 2nd the Noco.
I like my 2D a lot. Serves as both a charger and maintainer. Comes with mounting hardware for under hood

I use CTEK. Same brand GM uses for their Battery Protection Package option. I save a little money buying it direct but don’t get the Corvette logo printed on it.

I don't think you have to worry about fire with the "Batterytender" brand. They were originally designed for permanent installation in aircraft, and thousands are in use. They INVENTED desulfantion.
The auto ones sold at Northern Tool are waterproof and a great value.

It's got a little cradle that attaches with 2 screws, then a velcro strap that secures charger to bracket. The charger output has a couple eyes on the end of the output cord to connect to battery. Then I guess you could route the cord to somewhere outside the car like you would with a block heater cord?
I never mounted mine for a few reasons; I remove the battery from the car when in winter storage, I also use the charger with my motorcycle and finally, I don't like drilling holes in my car for stuff like this.
