  • Battery contact with a surface texture
    Patent number: 10511008
    Abstract: Battery contact with surface texturing. Exemplary battery contacts are located within a battery pack. The battery pack is operable to provide power to a device through a device contact of the device. The battery pack includes a battery pack housing, at least one battery cell located within the battery pack housing, and battery contacts including a positive terminal and a negative terminal. The battery contacts are configured to engage the device contact of the device and allow electric current to transfer from the battery pack to the device. The battery contacts define a surface having a surface texture. The surface texture includes raised portions for contacting the device contact to allow electric current to transfer from the battery pack to the device. The surface texture also includes recessed regions spaced away from the surface and for providing a space between the battery contacts and the device contact.
