What is Battery Voltage? Why the Voltage of Your Battery Matters
Lithium batteries, for example, typically have a voltage of 13.6V when fully charged in a 12 volt battery, while lead-acid batteries usually have a voltage of 12.7V when charged. The disparity between the voltages of each of these types of battery depends on the kind of chemical reaction occurring within the cells, which is the source of the voltage.

The voltage across the terminals of a battery, for example, is less than the emf when the battery supplies current, and it declines further as the battery is depleted or loaded down. However, if the device''s output voltage can be measured without drawing current, then output voltage will equal emf (even for a very depleted battery).
