Abstract

In a method for operating an electric device, which includes a first storage battery pack, a second storage battery pack and an electrical load, no more than one storage battery pack is discharged at any given time to operate the load. In the process, the storage battery pack to be discharged is selected as a function of a temperature of the first storage battery pack and a temperature of the second storage battery pack and/or as a function of an internal resistance of the first storage battery pack and an internal resistance of the second storage battery pack.
