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.
To accurately measure the instantaneous current output of a battery using a multimeter, follow these steps: Prepare the battery and multimeter: Ensure the battery is disconnected from any circuit. This is to prevent any external circuitry from affecting the measurement. Set up the multimeter: Set the multimeter to measure DC current.
The way the power capability is measured is in C 's. A C is the Amp-hour capacity divided by 1 hour. So the C of a 2Ah battery is 2A. The amount of current a battery 'likes' to have drawn from it is measured in C. The higher the C the more current you can draw from the battery without exhausting it prematurely.
