| || ||Two or more cells can be connected end-to-end to make a battery. A typical cell has a voltage of 1.5 volts (we write this as 1.5 V). By connecting cells in series, we can makes batteries with 3 V, 6 V and so on. |
Each battery is labelled with its voltage. This tells us about the push it gives to make the current flow.
A 6 V battery gives a bigger push than a 1.5 V cell.
Sometimes we call a single cell a battery, although technically we ought to say 'cell'.
