Is there a safe positive post adapter to provide quick connect-disconnect to a battery tender.
Like something that is permanent mount to the bat terminal. Maybe a simple #10 wire to
the connector post to catch the alligator clamp.

 

I use these type of ring connectors and then matching extensions to the battery tenders for all my cars.

 

Excellent and thanks!

I also use that type of wire extension so that while I can't even reach my battery when in the garage, the wire connector is near the front of the engine across from the battery and right next to my charger on the wall. In fact, if you wanted to run the wire through the grill, you wouldn't even have to open the hood.

Great idea. Thanks

 

I do something similar with my wife’s car, which sits in the driveway. Her car’s grill has enough space to tuck the cord (a four foot extension from the ring connector piece) behind the grill during normal days. When a cold winter night is predicted I use a 25’ extension from that cord from the grill, under the garage door and into another 25’ extension in the garage that goes up and over my cars to her battery maintainer on a shelf.
Did that after finding her hood frozen shut one morning and the battery was flat.
