    Default Charge new batttery at least 8hrs or overnight

    Whenever I buy a camera or a mobile phone, the vendor would almost always ask me to do that.

    Is there any basis for it?

    According to which "theorem" ?
    Do not be afraid [of ghost and bullies] Shoot them......

    Used to be the recommendation for ni-mh batteries, with li-on, not necessary.

    Check out batteryuniversity.com for the technical background

    the previous 2 answers are right. It's a holdover from the nickel battery days. Read you equipment manual. Those that I have (for cameras, phones, etc) have never mentioned the 8-hour / overnight charge. With the intelligent batteries and chargers necessary for Lithium based batteries, you'll see that charging stops once the full-charge is detected anyway - that doesn't take anywhere near 8 hours.

    As an ex-techie, I hear lots of howlers from salespeople (normally spoken with a degree of unjustified authority and experience too!). It lets me know which ones I should not trust
