1. A monitoring device for monitoring a functional capability of an accumulator for electrical energy of a battery, the accumulator including an electrolytic fluid and two connecting elements which are connected in an electrically conductive fashion to connecting contacts of the battery, the monitoring device comprising:
- an incorrect-position-detecting device configured to detect an incorrect position of the accumulator, the incorrect position being any position at which the electrolytic fluid could leak from the accumulator or come into contact with electronics arranged in the accumulator, the incorrect-position-detecting device including a memory device configured to store a duration of the incorrect position; and
a signal device configured to make available an incorrect position signal if (i) the duration of the incorrect position is longer than a predetermined minimum duration, or (ii) the duration of the incorrect position is equal to the predetermined minimum duration, andwherein;
the monitoring device is included in a discharge device for the battery, the discharge device including the accumulator,the discharge device defines a discharging current path configured to conduct a discharging current between the two connecting elementsthe discharge device includes a discharging switch configured to close the discharging current path, andthe discharge device is configured to change the discharging switch into a closed state as a function of the incorrect position signal.

Abstract
In order to monitor a functional capability of an accumulator for electrical energy of a battery, at least one position sensor is provided which outputs a position signal which is representative of the position of the accumulator. If the duration of an incorrect position exceeds a minimum duration, an incorrect position signal is output by a monitoring device.
