A battery-condition detection which requires no current sensor. The battery is connected to a microprocessor via a circuit configuration. This circuit configuration includes means for the voltage measurement, means for the voltage comparison and, optionally, for the temperature measurement, as well as means for generating a trigger pulse. This trigger pulse generates a voltage pulse at the battery. After averaging or filtering, the pulse response is utilized for determining the complex internal resistance of the battery, from which the battery condition is then estimated.
