I have spent my lifetime in the airospace field, primarily in instrumention, and know first hand that the myth about NiCads having memory is just that. Back in the 50's and 60's several of the major battery manufacturers tried their best to create such a trait in their NiCads and could not get any test results to substantuate the so called memory fault. True, NiCads wear out due to oxidation of their insulators but this is not memory, it is gradual loss of capacity that is not recoverable. Due to similar structure in NiMh, I doubt if they can ever be proven to have a memory either. Old myths die hard so if you must believe in NiCads having a memory, so be it; just don't bet your life on it.
If this is true, then what is it that makes a NiCad battery lose its ability to change to the full; something anybody who uses them knows only too well is happening?
