This thread talks about it pretty good. Post #6
And, that thread is accurate for my truck. I have not had a single problem since using the battery tender whenever the truck is sitting in my garage.

Interestingly, I always find I have to run the battery tender (max charging current 1.25 A) about 8-10 hours after driving the truck to bring the battery to a full charge. And, my alternator supplies around 13.9-14.1 Volts when I'm driving. So, even after a full day of driving, the battery seems to be (according to the way the "tender" works, at about an 80% charge level.

I cannot explain this, and it doesn't make any sense to me. It's just the way things are.
