The pride of my small tool-set is a "DeWalt DCD785C2-GB 18V 1.5Ah Li-Ion Cordless Combi Drill XR" it's the only thing I didn't buy a cheap brand. As I come to expand my tool-set after moving to a larger house/garden I'd like to invest in decent tools as they're likely to get a lot of use and I was wondering, if I stick with DeWalt is it likely they'll use standard battery packs so I can have a couple of batteries on charge and just slot them into whichever tool I need? Or would that be far too easy...?!
