Fantastic question @herbayomi.
In a nutshell, if you charge ur battery cell with a specified charger, let's just say a Li-ion battery, the positively charged lithium ions will move faster (not too fast, but moderately) from one electrode, which is cathode to another electrode, anode through an electrolyte solution on the battery cell.
So, during charging, the chemistry within the battery cell alongside with the right charger is perfectly OK. But if it's a charger that is below the battery volt, there would be a slow in action. The positive charge ions will move slowly to anode. It won't affect the b3 though, but it might in a long run.
It's like someone being thirsty for water, and was offered water using a teaspoon instead of a cup. If he take that water using glass cup, he would be satisfied quickly and be happy. Compare with using a spoon to take water, such person won't be happy and it would take much time before he gets satisfied. The same is our battery cells.
When you charge with appropriate charger, everything is cool, if low charger, the charging slows and if high rating charger than the battery voltage, this will result to a super fast charging making charged ions move faster from cathode to anode. This is not balance, if your battery get full and u refuse to remove it, it would affect the battery if using a dumb charger.
Thanks for coming around
Now this is CHEMISTRY!
I understand better now. Next time I am gonna get a charger, who ever is going to sell should anticipate some level of drama, as I am sure we that read your post have been equipped with the right knowledge.
Big thanks for this detailed answer...

You are welcome brov! Thanks for the compliment.
Of course i am! Gracias!
