A string of 12 NiCd cells connected in series produces approximately how many volts?

NiCd cells provide about 1.2 volts each. When cells are connected in series, their voltages add, so the total is the sum of all cells. With a string of twelve in series, the total ends up in the mid-teens, commonly rounded to about fifteen volts. If the pack is fully charged, each cell can be a bit higher, so the total is a little higher; if discharged, it’s a bit lower. The other numbers would require different numbers of cells or a different chemistry, so they don’t match the way series voltages add.
