Customer ServiceTo determine the amperage output of a 9V battery using a multimeter, you need to set the multimeter to the DC current (A) mode. Then, connect the multimeter’s positive (red) probe to the battery’s positive terminal and the negative (black) probe to the battery’s negative terminal. Finally, read the amp reading displayed on the multimeter.
The amount of current in a battery depends on the type of battery, its size, and its age. A AA battery typically has about 2.5 amps of current, while a 9-volt battery has about 8.4 amps of current. Batteries produce direct current (DC). The electrons flow in one direction around a circuit.
Turn on the electrical system of the device. Set the multimeter to measure DC amps. Ensure that the clips or alligator clips are securely attached to the terminals of the battery and the device. Read the voltage level of the battery with a digital multimeter or hydrometer-style battery tester.
Look at the reading on the meter display. The reading matches the battery label, if it's fully charged. You can work out the percentage charge in your battery by using a calculator to divide the meter reading by the figure on the battery's label and then multiplying the result by 100.
To get the voltage of batteries in series you have to sum the voltage of each cell in the serie. To get the current in output of several batteries in parallel you have to sum the current of each branch .
Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh). A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) the battery can provide for some amount of time (generally in hours). Voltage * Amps * hours = Wh.
