1. A method of operation for a battery-powered vehicle which is propelled by an electric motor, comprising the steps of:
- providing electric power from a first battery to power said electric motor while said vehicle is carrying said first battery and is carrying a second battery which is not connected to provide electric power to said electric motor,when the electric power in said first battery has been substantially exhausted, disconnecting said first battery from said electric motor and connecting said second battery to provide electric power to said electric motor,providing electric power from said second battery to power said electric motor while said vehicle is carrying said first battery, after said first battery has been disconnected from said electric motor,after said first battery has been substantially exhausted of electric power, has been disconnected from said electric motor, and has been carried by said vehicle while said second battery has provided electric power to said electric motor, removing said first battery from said vehicle and installing a third battery in place of said first battery,providing electric power from said second battery to power said electric motor while said vehicle is carrying said third battery which is not connected to provide electric power to said electric motor, andwhen the electric power in said second battery has been substantially exhausted, disconnecting said second battery from said electric motor and connecting said third battery to provide electric power to said electric motor.

Abstract
A battery-powered vehicle has two batteries which are replaced, rather than recharged in the vehicle. The vehicle is powered by only one battery at a time and that battery is used until substantially all of the energy the battery is exhausted. A discharged battery is replaced while the vehicle operates with the other, nondischarged battery. Preferred batteries have high energy density and may be of a type that is not rechargeable. An example is an aluminum-air battery. The non-rechargeable discharged batteries can be remanufactured to produce new batteries for further use in the vehicle.
