Just curious, why can't you build a deck with a battery powered drill? I
twisted lag bolts in two with my Dewalt 18V XRP but I can't remember if it

you don't stop on time!).

Roger, my answer to you (and others) was that batteries do not last
when the job is to just drive a screw after screw.

My 14.4v Bosch Impactor runs about 150 screws in half an hour before
the nicad dies and I swap 'em out. By the time that one's dead, the
first is charged and waiting for me. By the time that's done, I am,
too.

I can't find the review which showed how many screws were driven by
each model they tested on a single battery charge, but it was a good
one. Do look for it if you want real info, Ig.


Apparently, others' experience may be different, and, if so, I will
retract my comment about cordless drills.

The new lithium batteries, like the Makita 3Ah jobbers, are good for
about twice what I was getting.

Still not the one I looked for.
