Memory, True or False?
Answer is, false and true. There use to be a problem with memory in nickel cadmium batteries. It has now been virtually eliminated by the chemists at the battery manufacturing companies such as Sanyo, Varta, Panasonic etc… There still exists an affect called voltage depression which is not as severe as the old memory problem but does reduce the output voltage of a cell during a full discharge if the cell has been subjected to numerous shallow discharges prior. The cell has the current available to deliver but can’t deliver it at the normal cell voltage of 1.2 Volts, and may only deliver it at 1.1 Volts. This would correspond to a 1.0 Volt output voltage reduction in a 12 Volt battery pack.
