Capacity (measured in mAh - note the capitalisation) does not involve voltage, so placing three cells in series triples the voltage but the resulting battery has the same capacity. Placing cells in parallel triples the capacity with the same voltage.
Multiplying capacity by voltage will give you the energy in a battery, normally measured in mWh. Placing three cells in series or parallel will triple the energy.
So if I have a headlamp that requires 3 aaa NiMh (1.2 v 1000 mah each) rechargeable batteries to run the light and the battery pack in the light is setup in "series" then I have 3.6v output with 1000 mah capacity?
But if I try to put 3 li-ion 10440 (3.6v 600mah each)rechargeable batteries in the same battery case of the light (set up in series) then I get 10.8v output with the same 600mah capacity?
But if I set up the same 3 li-ion 10440 (3.6v 600mah each)rechargeable batteries in "parallel" in this headlamp then I get 3.6v output but with 1800 mah capacity? Is that correct?
