Need some advice here!! I will be sending my 14.4v DeWalt batteries out for a rebuild, and my choices for new cells are in the title of this thread. Should I go for the NiCd cells and get another 5 years out of them or invest a bit more for the NiMH? What are the benefits and drawbacks of either? As Jim B stated earlier LiON batteries are not a consideration at this time. Thanks!!
