    Since we don't know the description and specifications of that laptop's original battery and replacement battery, it's difficult to answer your question.
    I'm guessing you have an Acer Aspire 7740 laptop that came with Windows 7 or 8, 32-bit or 64-bit.

    What's the complete model number of that laptop?
    There should be a dash and additional numbers after 7740 that comprises the complete model number.
    What's the serial number and/or SNID number on that laptop?

    I don't know why your replacement battery isn't being recognized, so let me see if I can get one of the hardware experts to chime in.

    Could be defective or just incompatible. Despite what many third party battery makers claim, not all batteries work in all laptops. Genuine batteries are indeed sometimes required.

    Have you contacted the seller to ask them and see what they say?
