1. A device for interrupting the charging status of a rechargeable battery, comprising:

  • a plug for connecting to a power source;

    an outlet for receiving a plug capable of transferring power to the rechargeable battery;

    a switch configured to selectively be in either a closed state or an open state, wherein, the closed state corresponds to a charging state, the open state corresponds to a discharging state, and wherein-while the switch is in the closed state, electricity flows from the power source to downstream of the switch; and

    while the switch is in the open state, electricity does not flow from the power source to downstream of the switch; and

    a controller for controlling the charging state of the switch or the discharging state of the switch for reaching a predetermined modified charge level in the rechargeable battery,wherein an approximate amount of time the rechargeable battery must be either in the charging state or in the discharging state to reach to the predetermined modified charge level is determined by;

    gauging the charge level of the rechargeable battery;

    reading stored charge behavior data of the rechargeable battery; and

    extrapolating based on the charge level and the charge behavior data.
