pretty much the ni cds last longer then the ni mh because i still got 2 ni cd 2400 packs from 2 yrs. ago and still peak at same voltage as i got them and runtime dropped off by a lil bit. the 3000 batt. life died faster then the 3300 because my 3000 dropped off kinda big when they did drop but they are good prac. packs now and 3300 are better now.
