Hi Mark
One possibility is that Ni Cads can develop a "memory" if you
don't fully discharge them and then recharge them they will only discharge
to the level they were previously discharged to. Most Camcorder
manufacturers provide you with a load to discharge the batteries before you
recharge them. I guess this could lead to customer complaints regarding
battery life.
