Claim:
An electric padlock comprising: a lock casing confining a receiving space that is adapted for receiving a battery unit, and having a first end wall that is formed with first and second shackle insert holes, and a second end wall that is opposite to said first end wall and that is formed with a battery access hole, said battery access hole permitting insertion of the battery unit into and removal of the battery unit from said receiving space, said lock casing being formed with an insert groove in spatial communication with said receiving space and disposed adjacent to said battery access hole; an inverted U-shaped shackle member having first and second leg portions that are extended movably into said lock casing at said first and second shackle insert holes, respectively, one of said first and second leg portions being formed with a shackle groove; a latch member received in said lock casing and movable between a locking position in which said latch member engages said shackle groove so as to lock said shackle member on said lock casing, and an unlocking position in which said latch member is disengaged from said shackle groove so as to unlock said shackle member from said lock casing; and a battery cap unit including a battery cap member mounted movably on said lock casing for closing selectively said battery access hole, and a retaining member provided movably on said battery cap member, disposed in said receiving space when said battery cap member closes said battery access hole, and movable between a retaining position, where said retaining member engages said insert groove so as to inhibit opening movement of said battery cap member, and a releasing position, where said retaining member is disengaged from said insert groove so as to permit opening movement of said battery cap member; wherein one of said first and second leg portions of said shackle member is provided with a release-control segment adjacent to said battery access hole such that, when said shackle member is un locked from said lock casing and is subsequently rotated relative to said lock casing, said release-control segment is capable of driving movement of said retaining member from the retaining position to the releasing position.
