power supply voltage than the nominal battery voltage of my books is much higher

Power supply and battery to the books to the books is different powered

, battery powered, the battery output is pure DC, direct access to DC transformer module, the battery voltage is neither possible nor need to design very high, microelectronics circuit analog signals and digital signals to 5V voltage demand is now largely bounded by the efficiency and remove the transformer module pressure demand is sufficient,Dell inspiron 640m battery and lithium chemical emf determines the output voltage of a power-saving core only the left and right,

so many batteries are in series with three ways have become a very popular battery voltage. Some of the nominal value of the battery several times larger than the whole number, for example, or so, in fact, to protect the battery (a very small number of manufacturers will stop discharging the battery voltage set) or in the calculation of the design capacity of the battery when the tricky behavior. If you use a power supply,Dell e1405 battery the situation is more complex, first of all need to join the voltage regulator further filter to ensure that the power performance is not a good stable work situation, the voltage regulator after the two- pronged, all the way to the books Working power supply, another way to charge the battery, to supply books that part of the encounter with the same battery time, but that part of charging the battery through the battery charge control circuit can be added to batteries, the control circuit can be very complicated, it simply should include the primary regulator,

precision tunable regulator, SCR conditioning pulse output, voltage output, current feedback, the process of recording and computing chip charge, charge feedback regulation process parameters, etc.,Hp pb992a battery so supply voltage must be greater than the batteries have sufficient voltage margin pressure supplied to the charge control circuit of the unit. Really added to the batteries on the final voltage is not 16V, please rest assured that those who worry about.

power supply voltage than the nominal battery voltage of my books is much higher
