1. A method for charging a battery, wherein the battery includes an enclosure, comprising the steps of:

  • (a) providing an approximately constant current to the battery;

    (b) performing successive sampling operations of a first characteristic of the battery;

    (c) in response to the successive sampling operations, determining a one or more parameters of the battery;

    (d) comparing the value of the one or more parameters with a first predetermined value;

    (e) modifying the value of the approximately constant current supplied to the battery in response to a difference between the value of the one or more parameters and a first predetermined value; and

    (f) repeating the method from step (a) until the value of the first characteristic of the battery is determined to be equal to or greater than a second predetermined value.
