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.
