I HAVE HAD A BD 1/2" 18 VOLT DEWALT 1/2" 18 VOLT AND A RYOBI 1/2" 18 VOLT THE ONLY ONE THAT STILL WORKS IS THE RYOBI #2 WAS THE BD NOT HAPPY AT ALL WITH DEWALT THE BATTERIES FALL OUT OF MY DRIL SAWALL AND CIRULAR SAW

Personally I'd only use a Mains powered Hammer drill and more often than not it would be a Hilti.
I have a TE-50 that gets quite a bit of use.
With respect to cordless drills, I use a 14.4V Panasonic drill unit.
I've drilled through wooden power poles using an Auger bit with this drill I don't know how many times.
The biggest issue though with this drill, is not the battery going flat, but being careful your wrist doesn't get broken if it jams, mid-travel.
The batteries seem to keep a charge quite well too.
