I got tired of messing with alligator clamps and made my CTEK battery tender connections semi-permanent by attaching one end of the disconnect to the battery terminals.
Even during non-winter months my car can sit for weeks at a time, so I keep it connected to the tender. Just a quick unplug and I'm ready to go.
It's the original battery, now 5 1/2 yrs old.
