How is it that they can’t go up to 1.5 V and does this change anything within the electronics? For example, a Game Boy (why that particular example? Beats me!) running at 4.8 V instead of 6?
In: Chemistry
Different voltage is simply the result of different chemical elements.
alkaline batteries derive energy from the reaction between zinc metal and manganese dioxide. This reaction produces a potential difference of 1.5v
Nicd and nimh batteries use nickel oxide and cadmium (for the first) and a mix of metals for the second. 1.2v for both.
There are many battery types:
– zinc carbon (1.4-1.8v)
– lead acid (2v)
– liion (3.7v)
And many others.
6v batteries are created by putting 4 1.5v cells in series.
Electronic devices have some tolerance. You can run (usually) a device created for 6v at 5 or 4.5v. it will last less.
