People often use a common set of terms when talking about a battery''s voltage, capacity, current sourcing capability and so on. Cell. A cell refers to a single anode and cathode separated by electrolyte used to produce a voltage and current. A battery can be made up of one or more cells. A single AA battery, for example, is one cell.
