guys in tire shops that change tires all day everyday get a full day use out of a charge. They swap battires every morning and usually the battery they swapped out is not dead yet.

 

just watch that thing, they carry more power then one would think, i use them all day. i run dewalt instead, i actually own two half inch drives and a couple of compact half inch drives. they are awsome. i am constantly snaping self tappers off. only drawback with them is IT IS A GOOD IDEA TO CHECK THE NUTS BY HAND WHEN DONE!!!!! i have seen them run out of juice without the user not knowing it and they were tight when installed but worked themself's loose over time, and not much time at all. all in all its a great buy and any mechanic or service man should have one.

 

being in truck/equipment shop, thats all i use anymore. if i need to i will get out the air gun, but i love my electric. i have same one, with 3 batts, 2 chargers(1 wall, 1 car) the drill, led lamp and sawzall that all use same batt. i love it.

 

We use the Dewalts at work to build our warehouse racking, and I love them. Wish I could adopt on the bring home to the garage, .

 

Have read the specs on a comparable german brand( looks like bought from Snap-on) and they give a capability of 160(!) lug nuts per charge.
Changed all tires per hand today. Couldn't stop thinking about it...

 

i have one i got from a pawn shop for $155.00 plus tax
and i like it alot cause i don't have to drag out the air hose
it is like new and i agree with it being a bit heavier.
