Communications device with low energy notification

1. A wireless communications device comprising;

a power source that provides power to a device;

a power source monitor for producing a low energy notification upon determination of a low energy condition of the power source of the device;

a notification list comprising at least one other communications device to receive a low energy notification message; and

a notification transmitter for transmitting the low energy notification message to communications devices on the notification list, the low energy notification message comprising at least one destination address for the low energy notification message, wherein the notification transmitter further:

transmits the low energy notification message to a first remote communications device that is within communications range;

detects, during the low energy condition, a second communications device that comes within communications range during the low energy condition; and

transmits the low energy notification message to the second communications device.

2. The wireless communications device of claim 1 , wherein the at least one destination address is user specified.

3. The wireless communications device of claim 1 , wherein the power source monitor triggers a low power operating mode in response to the determination of a low energy condition.

4. The wireless communications device of claim 1 , further comprising a primary transmitter that transmits over a primary communications network, wherein the notification transmitter communicates the low power notification message over a secondary communications network.

5. The wireless communications device of claim 1 , further comprising a notification relay processor that receives low energy notification messages from other wireless communications devices and relays the external low energy notification messages to destination addresses contained in the low energy notification messages.

6. A wireless communications device comprising;

a power source that provides power to a device;

a power source monitor for producing a low energy notification upon determination of a low energy condition of the power source of the device;

a notification list comprising at least one other communications device to receive a low energy notification message;

a notification transmitter for transmitting the low energy notification message to communications devices on the notification list, the low energy notification message comprising at least one destination address for the low energy notification message; and

a location detector that determines a geographic location during the low energy condition, and wherein the low energy notification message contains the geographic location.

7. A method for communicating a low energy notification message from a device, the method comprising the steps of:

maintaining a notification list comprising at least one communications device to receive the low energy notification message;

determining a low energy condition of a power source of the device;

when a low energy condition is determined, transmitting the low energy notification message to the communications devices on the list, the low energy notification messages comprising at least one destination address for the low energy notification message;

receiving a second low energy notification message from another wireless communications device, the second low energy notification message comprising a second destination address; and

relaying the second low energy notification message to the second destination address; and

continuing the relaying while no longer in communications with the other wireless communications device.

8. The method of claim 7 , further comprising the step of accepting the destination address from a user.

9. The method of claim 7 , further comprising the step of entering a low power operating mode when a low energy condition is determined.

10. The method of claim 7 wherein the transmitting step comprises communicating the low energy notification message over a secondary communications network, and transmitting the low energy notification message over a primary communications network.

11. The method of claim 7 further comprising receiving, in response to the transmission of the low energy notification message, an acknowledgement message from the at least one communications device to receive the message.

12. The method of claim 7 further comprising:

transmitting the low energy notification message to a services server; and

receiving, from the services server, a location of a replacement battery.

13. The method of claim 7 further comprising initiating communications device discovery processing in response to the low energy condition.
