Don Perley writes: When hooked in series (head to tail) the volts do add up. Amp-hours do not add up. In the example where you have 10, 1.2V, C-cells connected to yield 12V, you *do* however get 10 times as many watt-hours as you would with one cell. A 12 volt bulb with the same power rating would take 1/10 as many amps as a 1.2 volt bulb. How long a 10 cell pack lasts depends on the power of your lamp, naturally. Steve J Kurt adds: Just as an added note: the amp-hour rating indicates how many hours the cell can supply a given current into some particular load. The voltage times the Ah gives the watt-hours (a measure of energy) that the cell can provide. When you hook a number of cells in series, make sure they all have the same Ah rating. Since they are hooked together in series, they will all be delivering/carrying the same current. The goal is to get them to run out of energy at the same time. If one runs out of energy before the others, the
