I've read the battery university link you dropped, I still did not see anywhere where it said charging with a smart charger is detrimental to a battery health. I'd ran a real-life tests with variety of batteries for more than eight years, in my experience I've never seen where a smart charger destroyed a battery simply because it was plugged in.

If you have a current below 100v you know what that means.

What do you mean by above?

The low current I'm talking about is not one given out by charger as a result of voltage drop. I'm talking about chargers outputting specified charging voltage and current as made by a manufacturer. Also the DC voltage output is the required nominal voltage value required by the said battery.
