What is Nominal Voltage?
The standard voltage used to express the capacity of a particular battery model. It is generally equal to its electromotive force or its approximate voltage during normal operation. Typical Values: o 1.2 volts per cell for NiCd and NiMH o 3.6 or 3.7 volts per cell for Lithium Ion or Lithium Polymer o 3 volts per cell for lithium primary o 2 volts per cell for sealed lead acid o 1.5 volts per cell for alkaline and carbon zinc .
