X2 on cordless 1/2 inch impact wrench, Santa brought me a Rigid last Christmas and already tackled a few projects on our class A with astounding ease. Sure gave my right arm quite a work out as it is pretty heavy, but removing bolts that would have required serious muscle, literally in seconds, don't know why I did not get one sooner. Tried the electric AC driven 1/2 inch and it just did not have the torque, probably why I didn't pull the trigger on the 20 volt version sooner thinking they have similar power. These newer batteries hold power for long periods of time, more than likely you will still have plenty of power remaining in the battery when called into service.
