As a general rule, the higher the voltage, the more charge the battery has. However, the relationship between voltage and state of charge is not always linear. For example, a fully charged 12-volt lead-acid battery will have a voltage of around 12.8 volts, while a partially discharged battery may have a voltage of 12.2 volts or less.
Most AAA batteries have a voltage rating of 1.5 volts, which is similar to other standard dry cell batteries such as AA, C, and D batteries. The voltage rating of a battery determines how strongly electrons are pushed through a circuit, much like pressure determines how strongly water is pushed through a hose.
Power = voltage x current. The higher the power, the quicker the rate at which a battery can do work—this relationship shows how voltage and current are both important for working out what a battery is suitable for.
