My Schumacher tender says not to leave unit connected to battery when not plugged into 120V ac. This is a different question, but why do you suppose they give that warning. It would be convenient to tuck the tender into the trunk and just leave the plug accessible.

I have had a trickle charger(1.6A max) on my garage queen for years. First battery lasted 6 years with this treatment so I doubt its done any harm. We dont get very cold here 5-40C/41-105F. Connect it after a run, red light lasts 4-6 hours before going green.
