Pager system with use monitoring

An electronic communication monitoring system comprising:

• a plurality of receivers, each receiver being connected to a battery and including a communication system to communicate information about the battery to a user of the receiver upon receipt of a specific code;
• a control unit coupled to a transmitter to signal each receiver, the control unit signaling each receiver by transmitting through the transmitter a specific code for the receiver;
• and
• a central unit directly coupled to the control unit, to a clock, to a first memory and to a second memory, the first memory and second memory receiving information relating to each battery, the central unit including a comparison device for comparing the contents of the first memory to the contents of the second memory and the clock output to detect an undesired situation and communicating the undesired situation to the control unit, wherein the control unit will signal a specific code to a receiver corresponding to the undesired situation which will activate the communication system to communicate information about the battery corresponding to the specific code received.

An electronic communication monitoring system comprising:

• a plurality of receivers, each receiver being connected to a rechargeable battery and including a communication system to communicate information about the rechargeable battery to a user of the receiver, each communication system configured to communicate upon receipt of a specific code;
• a control unit coupled to a transmitter to signal each receiver, the control unit signaling each receiver by transmitting through the transmitter a specific code for the receiver;
• and
• a central unit coupled to the control unit, to a clock, to a first memory and to a second memory, the first memory and second memory receiving information relating to each rechargeable battery, the central unit including a comparison device for comparing the contents of the first memory to the contents of the second memory and the clock output to detect an undesired situation and communicating the undesired situation to the control unit, wherein the control unit will signal a specific code to a receiver corresponding to the undesired situation which will activate the communication system to communicate information about the rechargeable battery corresponding to the specific code received.
