Abstract
A charger for charging a rechargeable electrochemical cell including: a first conductive terminal having a central opening therein and a first contact end, the first conductive terminal connected to circuitry capable of providing charging current at a first charging rate; and a second conductive terminal positioned within the opening, the second conductive terminal having a second contact end portion extending outwardly from and electrically insulated from the first contact end, the second conductive terminal connected to circuitry capable of providing charging current at a second charging rate. The charger may have an insulator with an insulating contact end portion in place of the second conductive terminal having a second contact end portion. Also, a rechargeable electrochemical cell for use with a charger including: conductive flexible positive and negative plates; the cell having a top end with a perimeter and a bottom end electrically connected preferably to the negative plate; an annular charging contact seat integral to and protruding outwardly from the top end and located on the top end away from the perimeter; and the charging contact seat in electrical connection with the positive plate. Additionally, combinations of a rechargeable electrochemical cell and a charger therefor are included.
