Abstract
A method and apparatus is provided which uses a plurality of batteries that are sequentially used to power an appliance. While one or more batteries are used to power the appliance, one or more spar batteries are charged for subsequent use. The rate of charge of the batteries is comparable to the rate of discharge of the batteries by the appliance or faster. Thus the appliance may be essentially continuously used by the user removing the discharged battery and inserting a charged battery.
