Abstract

A battery charger that allows insertion of a battery for charging. When the battery is inserted it mechanically engages an activation mechanism and electrically couples to an energy source incorporated with the charger. The mechanical engagement of the battery with the activation mechanism causes at least one vent in the energy source to open. The energy source generates power when the at least one activating gas infiltrates into the energy source through the at least one open vent. The power generated by the energy source is coupled to the battery for charging.
