<p>In a method for monitoring a state of a battery (1) of a radio-communications device (2), in particular a radio sensor and/or radio actuator, a message is generated by the radio communications device (2) and is sent via radio, the message being received by a control device (3), a count value of a counter (4,) of the control device (3) being increased by a pre-definable value after receipt of the message, which counter is assigned to the radio-communications device (2), and a battery warning message, which is associated with the radio-communications device (2), being generated and emitted at least indirectly if the count value surpasses a pre-definable threshold value.</p> |
