Splain this to me.
Does the thing have a timer, with a current sensor?
And what happens when it switches from red to green? (Besides the LED changing
color)
Is there a dual stage charging circuit, perhaps, where red = high charge rate
and green = trickle?
I'm always suspicious of these things since they're usually not sophisticated
enough to match what they do to the CCA/battery size and age.
And Tom, I think the clock is spring wound, and no current draw except for the
second or two it takes to trigger the electro_mechanical windup.

Subject: Re: [Roadsters] battery tender
I too bought a well reviewed battery tender off Amazon for my Datsun.
Not too impressed with it, on first use it stayed red for more than 72
hours,
which is the max it should have taken. I gave it another 48 hours, and
it finally went green. The unit (block that plugs into the AC power)
always feels a bit too warm even for when it is not actively charging.
My battery has always been quick to self-discharge (or the clock
is drawing too much current, which I don't think it is), and the
electrolytes
might not be completely in balance, which might be throwing the
battery tender into a confused state.
Tom.
