2.0Ah 18V Battery for Dewalt DCD950B
US$39.50
These are nice batteries and much cheaper than the dewalt ones. I don't know if it lasts longer than the OEM, buts works just as well. I haven't had any of the fit issues reported and I've used three of these batteries. The 2 amp hour ones also work well.
