Abstract

A device and method for storing and charging rechargeable batteries which are stacked within a charger housing, preferably with batteries being added to the top of the stack and removed from the bottom of the stack. Batteries advance from the top of the stack to the bottom of the stack under the force of gravity. Batteries towards the top of the stack are discharged through resistances, and those towards the bottom of the stack are parallely charged. Switches control which batteries are charged and which are discharged.
