In Reply to: But he's incorrect... posted by Chris Garrett on December 4, 2015 at 10:06:26:
The charger can be modeled as a voltage source in series with a resistance. If the voltage is higher than the cell is capable of holding safely, then there could be issues because there will be constant current flow into the cell due to the voltage difference. However, if the voltage source that the charger produces is well within the safe operating range of the battery then after a while the cell will (asymptotically) approach the charger voltage. After this point, there will be a direct connection but no more current flow. The key is the voltage source has to be well regulated DC, so that the cell can not and will not be overcharged.
If the cell can get heavily discharged, then it might draw too much current from the charger, depending on the charger series resistance. But charging discharged cells is a different question.
I don't believe it's worth arguing about terminology, especially terminology developed for a completely different battery technology, namely lead acid batteries.
