After the charging indicator light turns green, does it help to keep charging for another hour?

A: batteries. The Ni-MH/Ni-Cd battery is charged with a voltage of 8.7v. It is charged with constant current at first and then constant voltage. At the beginning the indicator is red, and the charging current is 0.6-0.8A during fast charging. The current is lowered to 200 mA at full charge. Even it is fully charged, and the indicator turns green, the charging continues at a low current to keep it as full as it can be. The lithium battery is charged with a voltage lower than 8.4 volts. The charging termination voltage is determined by the charger and the lithium battery (with a built-in protection board). Its charging method is mainly voltage detection. When the voltage reaches the threshold value, the internal circuit of the charger will be switched off immediately. It doesn't make sense to continue charging after the indicator turns green.
