Actually, voltage is dependent upon the chemistry of the reactions taking place - for nickel cells, this is nominally 1.2V, alkaline chemistry produces a nominal 1.5V, silver oxide cells a nominal 1.55V, Nickel-zinc cells a nominal 1.6V
This can be varied within quite tight limits, but the nominal voltage is intrinsic to the electrochemistry going on inside the cell.
- Yeah, I don't know why I wrote that. I have deleted the part where I said NiMH cells are 1.2V because of low resistance. Brted 19:26, 10 December 2010 (EST)
Somewhere it will be necessary to distinguish between batteries and cells
- Aren't all flashlight batteries single cells? I looked in my dictionary which has definition 1. as two or more cells connected, and 2. a single cell. So I think technically a battery is more than one cell, but cells are so often called batteries that the two are interchangeable.Brted 19:56, 10 December 2010 (EST)
