  "abstract": "Various embodiments of the present invention are directed at a method and system for recharging batteries for wireless electronic devices. According to one embodiment, a battery charging and monitoring system is disclosed. The system includes a host machine providing a plurality of charging slots and a plurality of wireless devices coupled to and powered by a plurality of batteries. The host machine is adapted to communicate with the plurality of wireless devices through a plurality of wireless links to monitor the plurality of batteries coupled to the wireless devices. According to another embodiment, an electronic device is disclosed. The electronic device is adapted to couple with at least a rechargeable battery and to negotiate with the rechargeable battery for an agreed range of power parameters. The electronic device is further adapted to accept power from and to provide power to the rechargeable battery at the agreed range of power parameters.",
  "claims": [
    "1. A battery charging and monitoring system comprising: a host machine including a plurality of charging slots; and a plurality of wireless devices coupled to and powered by a first plurality of batteries; wherein the host machine is adapted to communicate with the plurality of wireless devices through a plurality of wireless links to monitor the first plurality of batteries.",

    "9. The battery charging and monitoring system of claim 4 further adapted to assess the quality of each of the first plurality of batteries and upon finding a battery of unfit quality, find in the third plurality of batteries a battery of a compatible type, and communicate the location of the battery of unfit quality and the location of the battery of a compatible type to allow a user to replace the battery of unfit quality.",
    "10. The battery charging and monitoring system of claim 4 further adapted to assess the quality of each of the first plurality of batteries and each of the second plurality of batteries and upon finding a battery of unfit quality, communicate the location of battery of unfit quality.",
    "11. The battery charging and monitoring system of claim 10 further adapted to direct a user to an ecommerce site that sells rechargeable batteries of a compatible type with the battery of unfit quality.",
    "12. The battery charging and monitoring system of claim 11 further adapted to promote recycling of batteries, wherein recycling credits are allocated for the return of the battery of unfit quality for recycling.",
    "13. The battery charging and monitoring system of claim 12 wherein the recycling credits can be exchanged for goods and services in a network of stores.",
    "14. The battery charging and monitoring system of claim 12 wherein the recycling credits can be donated to charitable organizations.",
    "15. The battery charging and monitoring system of claim 12 wherein the recycling credits can be transferred between users.",
    "16. An electronic device adapted to: couple with a first rechargeable battery; negotiate with the first rechargeable battery for a first agreed range of power parameters; and configure the electronic device to couple to the rechargeable battery at the first agreed range of power parameters.",
    "17. The electronic device of claim 16 further adapted to: couple with at least a second rechargeable battery; negotiate with the at least second rechargeable battery for at least a second agreed range of power parameters; and configure the electronic device to couple to the at least second rechargeable battery at the at least second agreed range of power parameters.",
    "18. The electronic device of claim 17 wherein the first agreed range of power parameters and the second agreed range of power parameters are the same.",
    "19. The electronic device of claim 16 further adapted to supply power to the first rechargeable battery at the first agreed range of power parameters.",
    "20. The electronic device of claim 16 further adapted to accept power from the first rechargeable battery at the first agreed range of power parameters.",
    "21. The electronic device of claim 16 comprising a power storage configured to store power that can be used to temporarily power the electronic device in the event power from the first rechargeable battery is interrupted.",
    "22. The electronic device of claim 21 wherein the power storage includes a capacitor."
