Sounds about right. My Battery Tender Jr. will show a red light on hookup and followed with a red/green flash a couple minutes later. The red/green flash indicates the car's battery is at 80% of a full charge.

I see this even after driving the car for some distance and then parking it. Sometimes I won't connect the charger if I will use the car within a few days to a couple weeks. Anything after that, the charger goes on and stays there. I have sometimes left the Tender Jr. attached for 3 months at a time during the winter.

What you describe is exactly how my Battery Tender Plus works. Been that way ever since I bought it 8 years ago.

yes, normal. If I remember correct, it's explained on the package and the instructions what the lights mean.
