"There is controversy about whether the memory effect actually exists, or
whether it is as serious a problem as is sometimes believed. Some critics
claim it is used to promote competing NiMH batteries, which apparently
suffer this effect to a lesser extent. Many nickel-cadmium battery
manufacturers either deny this effect exists or are silent on the matter."
