i am intersted in the end of charge detection(-deltaV) on some NIMH chargers, i would like to test that effect on some chargers.
I got some chargers(like GP Smart power bank, GP H500,etc...),all the chargers i have use the drop of voltage as end of charge detection, so what i did is, I connected in serie to a battery a low ohmic resistance, i initiate the charge and after i while a short the resistor ,so drop of voltage but none of the charger did react to that drop,i manage to get a drop of 0.1V but still none of the charger i worked with reacted to that drop, so i would like to know if there are more criteria that i have to take in consideration to generate that drop?
