Hey man this is something very different and cool. You just require a visiting card and a nokia phone for this purpose.
Take a Nokia phone whose battery is completely drained out. Remove the battery and disconnect the middle connector with the help of a visiting card (please disconnect the middle one only and not the other two). Now put the corner of the visiting card in the middle of the phone and hold the card, Do not connect the middle connector with the battery while doing this and secondly connect the other two with the battery.
After you are done switch on your phone. Do not worry, at first it will show a message saying, “Insert SIM card” now you can remove the visiting card and there your battery is completely charged.
This trick does not work on all the Nokia phones.
It works best with 1108, 1100, 1112, 1600, 3100, 3120 etc.
