I need to replace the battery in my Dewalt drill. Last ones I bought on e-bay....worked out fine. I don't do much heavy work so my drill is only a 9.6v drill. Its been plenty for my needs. Looking again on e-bay I can get 2 (2000AH) Ni-CD batteries for about $35 or 1 (3000AH) NiMH for about $20. I've always bought Ni-cd batteries before. Which battery type do you prefer? Ni-Cd or NiMh?
