Does anyone have any recommendations of good battery operated Hammer Drill and Vacuum?

I bought a $700 hilti that ate itself (sparks coming out) when drilling into a 40 year old slab.

Your Hilti was battery powered? I find it difficult to imagine a battery powered one able to perform lots of holes without over heating.

I guess battery powered would be great if out on a large new slab or remodel where power is not close by. How bout a small generator on wheels?

On new construction a battery powered hammer drill is just fine. Drills enough holes no problem. However when I hit an old slab it overheated. Mine is an old ni-cad type battery. The Hilti people have told me the new Lithium Ion drills are far superior and there is no reason to have a cord any more.

Still haven't found a battery powered vacuum.

Here's some advice that I hope doesn't get me in hot water....

Use a can of compressed air to blow the dust out of the hole.

DeWalt makes a corded/cordless vacuum. I saw it in home depot.

Ni-Cad. The moment that goes Li-Ion I am getting one!

That one looks great! And not very expensive either!

I hated lugging a big vac around and trying to find power in a new building is impossible. Especially on a floor where nobody is working yet and temp power may be several hundred feet away.

You use an angle grinder for CaCl tests? That's not enough to get all the carbonation off.
