ABSTRACT:
A battery transfer apparatus and method according to the present invention provides continuous battery power to a battery powered device while changing batteries. Battery power is provided to the battery powered device from a charged battery while a nearly discharged battery is removed from the battery powered device. Battery power is also provided to the battery powered device from the nearly discharged battery while the charged battery is inserted into the battery powered device. The nearly discharged battery may be prevented from draining power from the charged battery during the transfer operation. A battery charger and battery condition indicator may also be included.
