Abstract: The present invention relates to a method for regenerating a Ni-Mh battery with a plurality of modules. The method comprises the steps of: performing, by at least one discharger, a first discharge of each of the battery modules at a first discharge rate until each module reaches a first predetermined cut-off voltage; performing, by at least one discharger, a second discharge at a second discharge rate, less than that used in step a), until each module passes from the first cut-off voltage to a second predetermined cut-off voltage; after the second discharge, cooling the modules for a determined cooling time until the temperature of the modules is below a threshold temperature; and after cooling, fully charging said modules at a determined charging current by means of at least one charger.
