I gave my grandson my old DeWalt 18V NiCad drill/driver a year ago & picked up an 18V LiIon DeWalt.
The old NiCad served me well, but, that ship sailed years ago. LiIon has it beat seven way to Sunday in weight (lower), life & faster recharge.
I'm curious - who's still using NiCad - or NiMH?
If so, is a switch to LiIon on the horizon?
