[Real or fake]

Hi thanks for your answers.I will try to post some pics in this reply.The battery is brand new but it is not a DeWalt oroginal i Think and that might be the reason for the bad performance.When i tested the grinder by cutting of a 5mm X 15 mm ``about the same as 0,2 X 0,6 inch``iron rod,it managed 5 Cuts Before the battery died. 

[Real or fake]

Hi,i have just bought a DeWalt DC 410 battery powerd grinder.It performs realy poorly so i suspect it might be a piratecopy.Is there any reliable way to tell if it is a real DeWalt.This model has the older style stick in battery and there is only two contacs to be seen when i look down where the battery will be inserted but on the battery there is three cntacts,are the third one on the battery just for the battaeycharger..

If anyone has any ideas please post a answer.

Best regards  Göran
