ABSTRACT:
An electric padlock includes a lock casing, a shackle member, a latch member, and a battery cap member. The lock casing is formed with a battery compartment to receive a battery unit, and a battery access hole. The shackle member extends movably into the lock casing, and is formed with a shackle groove. The latch member is received in the lock casing, and is movable to engage the shackle groove so as to lock the shackle member on the lock casing, and to disengage from the shackle groove so as to unlock the shackle member from the lock casing. The battery cap member is mounted movably on the lock casing to close the battery access hole, and is formed with a stop projection that engages the shackle member so as to inhibit opening movement of the battery cap member when the shackle member is locked on the lock casing.
