Abstract
An electrochemical cell is recharged in series with a constant voltage source and a resistor, wherein the charging current declines as a function of increasing cell voltage. When the change in voltage of the battery with respect to time decreases to near zero, the changing cycle is ended or converted to a maintenance charge.
