When the battery is not loaded, the terminal voltage is equal to the internal cell voltage, because there is no current flowing through the battery''sinternal series resistor. This is indicated by the solid blue line of Figure 1 and shows the actual cell voltage and the terminal voltage at no load.
Printable Chart Notes. 6V lead acid batteries are used in some DC devices like lights, pumps and electric bikes. You can also wire two in series to create a 12V battery bank. They are made by connecting three 2V lead acid cells in series.
Load Characteristics: The type of load applied (resistive, inductive, or capacitive) and its consistency can affect the battery''s voltage. A steady, low-resistance load will draw a consistent current, leading to a predictable voltage drop. In
A battery has an internal resistance. When you add a load on to it, it becomes a resistor divider. For example, assume you have a 12V battery and it read 12V exactly when measuring it. Imagine this battery has a 0.2 Ohm internal resistance. You then add a load of 10 Ohms. Use the voltage divider equation [Rload/(Rbat+Rload)]*Vbat = 11.76V
The voltage ranges are based on open-circuit voltage measurements (no load applied). Alkaline Battery Basics. Batteries are essential for powering many of your devices. Knowing about their chemical composition and the types available can help you choose the right battery for your needs. Duracell Coppertop AA Batteries with Power Boost Ingredients, 24
Open Circuit Voltage (Voc) is the voltage between the battery terminals when there is no load on the battery. Cut-off Voltage (Vco) is the voltage at which the battery is specified to be fully discharged. While there is usually charge remaining, operation at voltages lower than Vco can damage the battery.
The voltage ranges are based on open-circuit voltage measurements (no load applied) and assume a battery temperature of around 25°C (77°F). Basics of Battery Voltage and Capacity. Battery voltage indicates
The cut-off voltage is the minimum allowable voltage. It is this voltage that generally defines the "empty" state of the battery. Li-ion battery has a higher cut-off voltage of around 3.2 V. Its nominal voltage is between 3.6 to 3.8 V; its maximum charging voltage can go to 4– 4.2 V max. The Li‑ion can be discharged to 3V and lower
It may be observed from the exterior characteristic curve that the change within terminal voltage from no-load to full load is minute. The voltage at the terminal can be maintained constant by always regulating the R (field rheostat) routinely. Magnetization Characteristics of DC

Thus the nominal voltage is determined by the cell chemistry at any given point of time. The actual voltage produce will always be lower than the theoretical voltage due to polarisation and the resistance losses (IR drop) of the battery and is dependent upon the load current and the internal impedance of the cell.
Typical values of voltage range from 1.2 V for a Ni/Cd battery to 3.7 V for a Li/ion battery. The following graph shows the difference between the theoretical and actual voltages for various battery systems: The discharge curve is a plot of voltage against percentage of capacity discharged.
The voltage of a battery is a fundamental characteristic of a battery, which is determined by the chemical reactions in the battery, the concentrations of the battery components, and the polarization of the battery. The voltage calculated from equilibrium conditions is typically known as the nominal battery voltage.
Summarized below are some of the key technical terms used in battery specifications: Nominal Voltage (V) This is the reference voltage of the battery, also sometimes thought of as the “normal” voltage of the battery. Cut-off Voltage (V) This is the minimum allowable voltage of a battery.
Charge Voltage (V) This is the voltage that the battery is charged to when charged to full capacity. Charging schemes generally consist of a constant current charging until the battery voltage reaches the charge voltage, then constant voltage charging, allowing the charge current to taper until it is very small.
Usually battery terminal voltage is in the range V Bat,EOD≤v Bat(t) ≤V Bat,EOC. The end-of-charge voltageV Bat,EOC is typically declared by the manufacturer. The end-of-charge voltage is used to initiate the termination of the charge process or to start with constant voltage charge mode (‘CV charging’).
