Ya they do everything from a 1 cell (glow) to 8 cell and automaticaly changes the voltage for you so you dont screw it up! but it will only charge Ni-mh and Ni-cd... that is all i will ever doo anyways. lol. and i charged a 7.2 stick today 1500Mah Ni-mh and it took 37.56 minits on 1 amp charge... and the max is 4.8 amps to charge at.
