ABSTRACT:
A rechargeable battery (208) is charged using a charger (202). The charge current provided by charger (202) is a stepped-down pulse where the battery charge current rate change is determined by the rise time of the battery voltage. The charge pulse sequence is repeated after the polarization recovery period is completed. The polarization recovery time of the previous period will determine if the stepped-down pulse has to be modified.
