Lead-acid storage battery recovery system using on–off constant current charge and short–large discharge pulses

We report a method of recovering degraded lead-acid batteries using an on–off constant current charge and short–large discharge pulse method. When the increases in inner impedance are within ∼20% of the initial impedance value, their system will permit discharge times to recover to a level approxima...

Zusammenfassung:	We report a method of recovering degraded lead-acid batteries using an on–off constant current charge and short–large discharge pulse method. When the increases in inner impedance are within ∼20% of the initial impedance value, their system will permit discharge times to recover to a level approximately matching their initial time values. In one experiment, when the discharge time of a
