Numerous tests have proved that verification of the dell replacement laptop battery HW879 for latitude E6400 will not help promote its capacity. The so-called laptop batteries verification refers to so deep a charge and discharge of the battery, when its actual capacity is different from the recorded capacity of its control circuits, as to let its control circuits refresh the records which can be made to approach the actual situations of the battery. But such operation is only aimed at running users in for a sight of the real capacity of the battery, which can hardly qualify itself as a promotion of its capacity. The most pivotal factor is still the actual capacity of the battery. If the actual capacity of your battery is higher than what is recorded in the control circuits, the verification can make the battery appear as if its capacity had been increased; if, on the contrary, its actual capacity is lower than what is recorded in the control circuits, then the verification will set the battery to seem as if its capacity had been reduced.
Over the years that has been the cause of ceaseless arguments about verification effect among many people. But users are still reminded not to get misled by these data issuing from the verification situations, in that the verification is simply intended for such an exhibition of the true capacity of the dell replacement laptop battery HW879 for latitude E6400 as serves to eliminate the deviations between the battery and the control circuits. Whether the displayed capacity is on the increase or on the decrease cannot be determined by the outcome of a verification of the state of the battery itself.
