Voltage Depression ("Memory Effect")

Voltage Depression ("Memory Effect")
  • Voltage depression is a scientifically measurable characteristic of all batteries, however, Ni-Cd batteries demonstrate particularly acute sensitivity.
  • Voltage depression from repeated partial discharge can be reversed through
    charge cycling (see figure below).
  • A properly designed application with Ni-MH batteries will result in neither
    permanent performance loss nor perceivable temporary capacity decreases from this characteristic.
