The term "voltage" in a battery refers to the difference in electric potential between the positive and negative terminals of a battery. A greater difference in potential results in a greater voltage. Electric potential means the difference in charge between two points–in this case, the two terminals of a battery.
Batteries range in voltage from a few hundredths of a volt to many hundreds of volts, depending on both the size of the battery and the materials from which it is made. They are an excellent way to power various forms of devices, no matter what the voltage requirements of those devices. Donat, Wolfram. "What Is Voltage In A Battery?"
The greater the difference in potential charge, the higher the voltage. For example, on the negative end of a battery terminal, there’s an excess of electrons, whereas the positively charged terminal has a lack of electrons. The more electrons that the negative terminal has compared to the positive terminal, the higher its voltage.
We noted that 12.6-12.7 Volts is the normally voltage for a fully charged battery, and showed which voltages correspond to which approximate charge % level. Be aware with analysing voltage – it doesn’t show the health of the battery per se, it just shows how much charge is in the battery at the moment you measure.
Volts refer to the potential energy within a battery, whereas current refers to the rate at which the electrons are flowing. Voltage is measured by volts (V), which represent the difference in electrical potential. Current is measured by the speed of the electrons, which are represented by amperes (amps).
Battery voltage charts describe the relation between the battery's charge state and the voltage at which the battery runs. These battery charging voltages can range from 2.15V per cell to 2.35V per cell, depending on the battery type. You can check or read a battery's voltage using a multimeter.
