Long live the NiCad battery, It is a much better solution then most, and has few drawbacks except for weight. They are still in my future until they quit making them. A goof proof battery if there ever was one. Those Sub C's would take a lot of neglect and abuse and still do the job. My Makita drill used them, run everyday, for years, fast charged, run completely flat sometimes. LiFe batteries are going to be, the go to battery for most people as time goes on but I still think NiCad's should not be ruled out quite yet. Those Eneloops have a future but not as receiver batteries.
