At its most basic, battery voltage is a measure of the electrical potential difference between the two terminals of a battery—the positive terminal and the negative terminal. It’s this difference that pushes the flow of electrons through a circuit, enabling the battery to power your devices.
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.
Check the voltage reading: The multimeter will provide a measurement of the battery’s voltage. A fully charged battery should have a voltage reading of around 12.6 volts. If the reading is significantly lower, it indicates that the battery may be discharged or unable to hold a charge. 2.
Set the range to a value higher than the battery’s nominal voltage to avoid any potential damage to the device. For example, if you are testing a 9-volt battery, set the range to 20 volts. Next, take the red probe and connect it to the multimeter’s positive (+) terminal. Then, take the black probe and connect it to the negative (-) terminal.
A fully charged battery should read around 12.6 volts. If the voltage reading is significantly lower than 12.6 volts, charge the battery using a battery charger and retest. If the voltage does not increase, the battery may be defective and needs to be replaced.
By measuring the voltage across the battery, its remaining capacity can be preliminarily estimated. The constant current discharge method is a more accurate battery capacity test method. Connect the battery to a certain load and discharge it at a constant current until the battery voltage drops to the predetermined cut-off voltage.
