Ni-Cd battery discharger circuit
The greatest shortcoming of Ni-Cd battery is: it has memory effect, an effective method to eliminate memory effect is: to fully discharge the Ni-Cd battery before its third or fourth charge, that is charging to Ni-Cd battery after its single section voltage drops to 0.75V, this way can make Ni-Cd battery recover capacity in time then to ensure it for normal use, but the final voltage of every single section Ni-Cd battery shouldnot belower than 0.65V, or else Ni-Cd battery will be polarity reversed and damaged due to over discharge.
