I believe the confusion arises from the recommendation that a few *deep* discharge/charge cycles be to "erase" the cell's memory. In other words, if a nicad that is capable of supplying X amps is operated for a significant period at a load of Y amps where Y is significantly less than X, the nicad will, subsequently, be unable to supply X amps even though it is "fully charged". While it is often recommended that such a nicad be subjected to several deep discharge/charge cycles to restore it to its original discharge *rate* specification, care must be exercised in the case of batteries for the reason mentioned in my first paragraph (ie possible reverse charge of one or more of the cells).
