Main performance parameters of the battery–two
Rated Capacity
In the conditions of the design requirements(such as temperature, discharge rate, termination voltage, etc.), the battery should be able to release the minimum capacity, the unit is in ampere-hours and signed as C. Capacity is greatly influenced by the discharge rate, so often in the lower right corner of the letter C ,the discharge rate is marked with Arabic numerals, such as C20 = 50 shows that when the rates is 20 ,the capacity is 50 ampere-hour . Theoretical capacity of the battery under the battery electrode active material reactive in the amount and calculated according to Faraday's law of electrochemical active substances equivalent spectra. As the battery side effects may occur, and the special needs of design, the actual capacity of the battery is often lower than the theoretical capacity.
Rated Voltage
The typical operating voltage of Battery at room temperature, also known as the nominal voltage. It is used in reference to different types of batteries. Actual battery voltage varies with different conditions. Battery open circuit voltage is equal to the difference of the positive and negative electrode potential electrode balance. Only with the type of electrode active material, whereas the number of independent and active substances. The battery voltage is essentially a DC voltage, but in some special conditions, the electrode reaction caused by the metal crystals or films of certain phase transition into phase voltage will cause small fluctuations, a phenomenon known as noise. Volatility is small but very wide frequency range, so the circuit can be distinguished from self-excited noise.
