Wired in a series, they total 4.5v output.
If three AA batteries are wired in series (as in a flashlight) is the result just a stronger 1.5 volt, or do they add to make 4.5 volts?
My batteries are very good at math and add up to 4.5 volts. They're so into math they bedazzle their outfits with a + and -.
