    Wow, thanks. I was half expecting that I would probably lose data.

    Although you don't lose data it's bad for
    your battery to run it out completely.

    hmm why's that? I wanted to a full dis-charge of the battery before charging it fully again.

    This is what wikipedia says:

    Lithium-ion batteries should never be depleted below their minimum voltage (2.4 to 2.8 V/cell, depending on chemistry). If a lithium-ion battery is stored with too low a charge, there is a risk that the charge will drop below the low-voltage threshold, resulting in an unrecoverable dead battery.[citation needed] Usually this does not instantly damage the battery itself but a charger or device which uses that battery will refuse to charge a dead battery. The battery appears to be dead or not existent because the protection circuit disables further discharging and there is zero voltage on the battery terminals.
