How many volts a battery has depends on its chemistry and cell count. 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.
This voltage can tell us a lot about the battery’s state of charge (SoC) – how much energy is left in the battery. Here’s a simplified SoC chart for a typical lithium-ion battery: Understanding this relationship is crucial for several reasons: Performance: Devices are designed to operate within a specific voltage range.
Nominal Voltage: This is the battery’s “advertised” voltage. For a single lithium-ion cell, it’s typically 3.6V or 3.7V. Open Circuit Voltage: This is the voltage when the battery isn’t connected to anything. It’s usually around 3.6V to 3.7V for a fully charged cell. Working Voltage: This is the actual voltage when the battery is in use.
Traditional 12-volt lead acid car battery will have a nominal charge of 12.6 volts when fully charged. It is best to aim for a car battery voltage of 12.6 volts when the car is off. The voltage should rise to 13.5 to 14.5 volts when the engine is running due to the alternator boosting it.
Batteries generate voltage through a chemical process involving anodes, cathodes, an electrolyte, a separator and a circuit. The circuit serves to connect the anode and the cathode, enabling electrons to move from the anode to the cathode, thus generating voltage.
Voltage is a measure of energy per unit charge and is measured in volts. In a battery, voltage determines how strongly electrons are pushed through a circuit, much like pressure determines how strongly water is pushed through a hose. Most AAA, AA, C and D batteries are around 1.5 volts.

The Ultimate Guide to EcoFlow Portable Power Station Specs
AC Output indicates the maximum number of watts (electricity) the portable power station can deliver on-demand simultaneously. If any appliance you want to operate exceeds the AC output, the PPS can''t run it. Similarly, the total wattage of all the appliances you want to operate at the same time can''t exceed the maximum AC output — in this case, 3600W.
