Also,repeatedly charging Ni-MH batteries that are only partially discharged can cause them to suffer from the ?memory effect?. Ni-MH batteries that are ?deactivated? or affected by ?memory? suffer from the problem of only providing power for a short time after being charged.

By repeating this cycle several times, the temporary reduction in performance caused by ?memory? or ?deactivation? can be remedied and the batteries can be restored to their original performance levels. ..."
