This C12 is about 7 years old...I had not used it for about 3 years as the batteries do not hold a charge. I have one Festool NiCAD battery that can be re-built. I have used it with a shentec battery and it operates well. You can also buy a new Festool battery or knockoff. I have the syscontainer and charger, Included are the centrotec chuck as well as the regular chuck and a 90 degree angle chuck.. $90+shipping
