Alan,you can use a voltage divider.Get 10 each 1megaohm resistors and hook them up in series.Hook one end to the cell positive and the other end to ground.Then hook the scope probe between the 9th and 10th resistor.That would be closer to the ground end of the resistor dividers.This will give you a divide by 10 output to the scope.With a probe set on 10x and this divider,you'll get 100:1 ratio.
