Abstract: A battery transfer device having a base, a plurality of multidirectional rollers coupled to the base, and a winch coupled to the base. Each of the rollers is configured to rotate about at least a first axis and a second axis that is positioned at an angle with respect to the first axis. The winch has a cable or rope configured for coupling to a battery, and the winch is operable to pull the battery across the rollers. Guides may be removably coupled to the base adjacent one or both sides of the base. A method of using the battery transfer device to remove a battery from a battery rack or install a battery in a battery rack.
