An overview of laptop battery technology

Although it doesn't undermine the veracity of the posted article, the "nicad memory effect" is a myth, perpetrated by the battery manufacturers for the most part. Google around for the stories... it's pretty amazing.

Sure, Nicads wore out, and you could accelerate that by overcharging, but "fully draining" them was never the proper solution except for the earliest "timed" chargers rather than the later charge-sensitive chargers.

You might want to read what the Buchmann site says about memory effect on NiCads and NiMh batteries. There is a lot of detail about what goes on chemically and the various charging methods available:

It does appear that there is a memory effect for NiCads and NiMh batteries.
