A fixing mechanism to fix a battery to a main body of an electronic device includes a channel defined in the main body, the channel comprising two opposite openings at two ends thereof, a first fixing member fixed to one end of the channel, an electrically conductive second fixing member fixed to the other end of the channel, an insulated protector slidably positioned in the channel between the battery and the first fixing member; an electrical conductive member partially received in the insulated protector, and a resilient member. One end of the resilient member is fixed to the first fixing member, and the other end of the resilient member resists the electrical conductive member with the insulated protector toward the battery so that the electrical conductive member is electrically connected to an electrode of the battery.
