The disclosure concerns a method for determining a predicted state of health of a device battery in a battery-operated machine. A state of health characteristic model for a state of health time characteristic is provided using a number of linked parameterizable characteristic functions that each indicate a state of health over a time period of ageing times, the characteristic functions being initially parameterized. A number of data points are captured that each indicate a state of health and an ageing time. A parameter of one of the characteristic functions is adapted based on the data points in the respective time periods of the characteristic functions. A parameter of another of the characteristic functions, for which there is no data point available, is also adapted. The state of health characteristic model is provided based on the adapted characteristic functions.
