Buy a new laptop charging how long is appropriate? May most businesses will warn you to three charge three put, the so-called first three secondary full 12 hours, and the battery to be discharged to continue charging. This argument is not scientific, proved such a practice is not scientific, the new notebook how to charge time, what do not like it? Writer's Asus A32-F82 Battery works for everyone to be detailed answers.
1 in order to facilitate understanding, look at the the core battery works. Figure: intact batteries, capacity and design capacity is basically the same, and have done the state ruler correction. The red line shows the ruler line assumes that each battery capacity of 100W / H 2 the total capacity of the power-saving core is 200W / H.
2, after use for some time, it is assumed that only one of the saving core a small amount of the aging state when not done to scale correction when the actual capacity of 180 W / H.
3 2 Battery correction, the correction results obtained theoretically should ~ accordance with the calibration settings, the protection of the power will be balanced in accordance with the battery state of the worst, this time after the correction capacity will become 160W / H ratio is not before correction less 20W / H.
4 Suppose, causing the Asus N61 Series Battery, due to the substantial discharge capacity is reduced further in the process of correcting two battery. Correction when performing heavy use and so on. Battery protection chip in accordance with the "bucket theory" in accordance with the batteries of the worst balance, the total capacity is 100W / H. At this time, in fact the capacity of the batteries and no obvious loss, but decided due to the state of the batteries, the batteries fact is never full, unless the batteries back to normal, otherwise the 2nd The batteries will never restore electricity.
5,Why some correction will increase the power problem. Pictures, green is the parameters set by the internal battery, and red is your battery's actual loss parameter (the head of the curve should be straight, but Office effort bad, the curve is not straight), therefore, under certain conditions, perform rigorous scale correction will increase in electricity consumption.
6, the so-called "three complete charge and discharge" is how to. Actually comes from selling the merchant for-cell battery, the course early nickel-cadmium battery needs, but now are lithium batteries. Plug-speak, this is for the core after completely charged and discharged batteries, if there are four batteries, not the so-called "three charge three put batteries in more than one transfer point suddenly power down .
7,After "three charge three put, the state of the batteries, the batteries of the worst balance ~ ~ ~
8 ,Asus UL20A Battery power-down explanation, general suddenly fell to 15% in the last 5% that is normal, because the process of the core production of each home appliance manufacturers, since the last power consumption, and the remaining charge, the lithium-ion movement is hindered appears on the surface of the battery power-down phenomenon, which will be executed normal ruler correction. Course of this phenomenon and the batch of batteries.
