BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure relates to a battery holder. 
         [0003]    2. Description of Related Art 
         [0004]    In many computer systems, button batteries are commonly used to power complementary metal oxide semiconductor (CMOS) chips on motherboards. However, sometimes, a button battery may be loosened, and as a result, the CMOS chip will stop working, which is undesirable.

     DETAILED DESCRIPTION 
       [0009]    The disclosure, including the accompanying drawings, is illustrated by way of example and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one. 
         [0010]    Referring to  FIGS. 1 and 2 , an exemplary embodiment of a battery holder in which a button battery  10  may be installed includes a base  20  and a cover  30 . 
         [0011]    The base  20  includes a substantially circular bottom wall  22  and a first sidewall  24  extending in a substantially perpendicular manner from the circumference of the bottom wall  22 . A first receiving space  26  is bounded by the bottom wall  22  and the first sidewall  24 . A rectangular slot  220  is defined in the bottom wall  22 . A first conductive piece  222  is mounted to the bottom wall  22  in the receiving space  25  at a first end of the slot  220 , and slants up toward the second end of the slot  220  opposite to the first end in the first receiving space  26 . Two pins  224  (anode pin  224  and cathode pin  224 ) extend in a substantially perpendicular manner from the outer surface of the bottom wall  22  opposite to the receiving space  26 . The cathode pin  224  is located at the first end of the slot  220  and is electrically connected to the first conductive piece  222  in the bottom wall  22 . The other pin  224  is located adjacent to the second end of the slot  220 . Two diametrically opposing recesses  240  are defined in an outer surface of the first sidewall  24 . A latching hole  242  through the inner surface of the first sidewall  24  is defined in each recess  240 . A second conductive piece  28  is mounted in one of the recesses  240 , and extends through the bottom wall  22  to connect to the other pin  224 . A through hole  280  is defined in the second conductive piece  28 , aligning with the latching hole  242 . An extension piece  282  extends in a substantially perpendicular manner from the second conductive piece  28  to contact the top side of the latching hole  242 . 
         [0012]    The cover  30  includes a circular top wall  32  defining an opening  33  in the center and a second sidewall  34  extending in a substantially perpendicular manner from the circumference of the top wall  32 . A second receiving space  36  is bounded by the top wall  32  and by the second sidewall  34 . A circular third conductive piece  320  is mounted on the inner surface of the top wall  32 . Two inwardly-acting opposing latches  340  extend from the second sidewall  34 , away from the top wall  32 . Each latch  340  includes an elastic extension portion  342  extending from the second sidewall  34 , and a hook  344  extending from the distal end of the extension portion  342  toward the other latch  34 . A fourth conductive piece  38  forms the outer face of the inner surface of one of the hooks  344 , and the fourth conductive piece  38  extends through the corresponding extension portion  342  and the second sidewall  34 , to be connected to the third conductive piece  320 . 
         [0013]    Referring to  FIG. 3 , in assembly, the button battery  10  is received in the first receiving space  26 . The cathode of the button battery  10  makes contact with the first conductive piece  222 . Therefore, the cathode of the button battery  10  is electrically connected to the cathode pin  224  at the first end of the slot  220  through the first conductive piece  222 . The cover  30  is placed on the base  20 . The extension portions  342  are received in the corresponding recesses  240 , and the hooks  344  engage in the corresponding latching holes  242 . Therefore, the cover  30  is fixed to the base  20 , and button battery  10  will not be loosened. At this time, the fourth conductive piece  38  is electrically connected to the second conductive piece  28 . The anode of the button battery  10  extends into the second receiving space  36  and contacts the third conductive piece  320 . Therefore, the anode of the button battery  10  is electrically connected to the anode pin  224  at the second end of the slot  220  through the third conductive piece  320 , the fourth conductive piece  38 , and the second conductive piece  28 . 
         [0014]    It is believed that the present embodiments and their advantages will be understood from the foregoing description, and various changes may be made thereto without departing from the spirit and scope of the description or sacrificing all of their material advantages, the examples hereinbefore described merely being exemplary embodiments.
