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.
A battery’s capacity is commonly rated at 1C, indicating that a fully charged battery rated at 1Ah should provide 1A of current for one hour. By adjusting the discharge rate, the battery can provide different levels of current over varying durations.
Since this is a particularly confusing part of measuring batteries, I'm going to discuss it more in detail. Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh).
Voltage * Amps * hours = Wh. Since voltage is pretty much fixed for a battery type due to its internal chemistry (alkaline, lithium, lead acid, etc), often only the Amps*hour measurement is printed on the side, expressed in Ah or mAh (1000mAh = 1Ah). To get Wh, multiply the Ah by the nominal voltage.
Voltage in batteries indicates the measure of electrical potential energy stored in the battery. It represents the electric potential difference between the negative and positive terminals of the battery. Voltage determines the force with which electrons flow in a circuit and influences the overall performance of the battery.
However, the amount of current we can really draw (the power capability) from a battery is often limited. For example, a coin cell that is rated for 1 Ah can't actually provide 1 Amp of current for an hour, in fact it cant even provide 0.1 Amp without overextending itself.
Thus, the power P in watts it equal to the voltage V in volts times the current I in amps. For example, let''s convert 12 volts to watts for a DC circuit with 2 amps of current. P (W) = 12 V × 2 A
