I'm actually buying a replacement battery (after 4 years of use), but wanted to add a quick comment that this has been a favorite tool of mine. I put together computers, screw network eqpt. into equipment racks and occasionnaly use it to torque wood screws into pine 2x4's and occasional drilling into sheet metal as well as other light tasks. It travels well and has good battery life and surprising torque for a 2.4v device. I'm presuming no one buying this will be delusional enough to think they're goingto drive tapcons into concrete with this thing, but for "light duty" this is a gem. I used to buy craftsman and black&decker, but both are a mere shadow of their old selves, most notoriously, B&D is now simply a marketing firm for lowest bidder import junk tools. This tool is the real mccoy.
