Full power is impossible, no one will use the full power after the battery into the internal structure and battery performance is not stable. Specific to how much the state of charge, What is the best value, not only the value of a different material system, a different level of technology, its results are not the same. The computer batteries is to make the battery aging, stable performance qualified only.
Main criterion is some general properties: A battery's capacity. This is a prerequisite for the standard. (2) the battery internal resistance, thickness, and voltage. Into a bad battery internal resistance, main polarization reason, uneven polarization into after aging did not meet the purpose of the battery performance stability. Voltage Well, you can simply judge the battery's charge capacity, but also many electrical appliances automatically determine the standard. Three cell cycles, storage, shelving performance. Capacity of qualified and can not explain you into steps is reasonable, because a lot of the problem is only in the late exposure. If the battery into a bad, even if you start capacity qualified, at a later stage, due to the negative embedded lithium uneven or poor electrolyte dispersion instability, will certainly affect the cell cycle, storage performance, there will be a large number of irreversible capacity loss. . This is why some friends: battery internal resistance will change in the set aside a period of time circulation drum shell, or set aside some time one of the reasons of the low capacity. The conclusion is: the battery formation is not full, the charge and the number of (state of charge), aging, determined by the material system and process performance requirements, specific values have to do their own experiments to determine.
We now use the full power aging is prefilled battery into the charge voltage above 4.17V, the battery aging. Now we are going to semi-electric battery aging 3.80-3.90V battery aging. But I find the theory based on lack of guidance!
There is no theoretical guidance, there is no experience to guide, or even the whole company, no one to study the principles, but also no one to investigate. Many so-called theoretical guidance, can be found in any one lithium textbooks books, Acer batteries is not highly theoretical, but common sense. Such right is not no correct conclusion, parallel to do N experiments, the blind men feeling the road just concluded cycle slower but as long as the boss money, get a few more experiments can still draw the right conclusion. Your story is very rigorous, pre-filled and turned into what is the relationship? What is pre-filled? What is a Chemical? What is aging? What is aging? I see do not understand.Into an operating battery has a capacity of the battery of a pre-charge activation is also known as pre-charge, (electric) activation, (e) activation, the battery has stable charge and discharge characteristics the front steps. Aging have explained earlier, before the battery into shelved, this time set aside primarily to the electrolyte uniform full infiltration of the batteries. Aging will have on the battery pre-charge, which we call into. Aluminum battery usually open into, because the gas into the process, opening into the into the production of gas discharged from the liquid injection hole. Into the process, the batteries have capacity, but is not stable, the battery internal polarization of lithium intercalation uneven. Therefore, in order to avoid damage to the structure of the battery and to prevent the embedded lithium uneven and caused the irreversible capacity loss (or potential is not irreversible capacity loss, this part of the impact of is the cell cycle and storage performance), usually using a small current will be battery slow activation charge to about 70% of capacity set aside, leaving part of the capacity space for the battery to further maturation, this period includes a period of stability of the SEI film. This is to shelve the steps we usually talk about aging, also called maturation, is generally applied to the temperature (ie, above room temperature) aging can be called high-temperature aging. Textbooks are written.

Laptop Battery Consumption Up to 20%
Notebook PCs have become an essential tool for many people working and living, as the core components of the laptop - the battery, the life of just how long? 360 hardware guru survey found that 60% of notebook battery loss rate as high as 20% battery life, more than 80% of accelerated consumption.What is the rate of cell loss? Online pass "battery fridge can fix" is really feasible? Why the battery life is less than half of the bought when? To buy a new battery, what quality? Recently, 360 security hardware master defender's 360 staff 11 to unlock these mysteries.The larger the cell loss rate the lower the battery ability to save electricity360 security experts explained that the cell loss refers to the battery after prolonged use, the actual capacity of the smaller, lower than the nominal capacity. Quantification of cell loss rate of cell loss, it's the formula: (factory design capacity - fully charged capacity) / factory * 100% of the design capacity. Obviously, the greater the rate of cell loss, the ability to save electricity, the smaller the corresponding endurance worse. Cause the battery to loss of a variety of reasons:1) use of poor quality charger.2) high or low temperatures for a long time job.3) over-charging and discharging (battery remaining capacity is less than 3%).4) Long-term use of radiation in the electromagnetic strong battery (may interfere with the conductivity of the metal in the battery).5) long-term use the battery in wet conditions (wet battery performance).How to understand the rate of loss of your own laptop battery?Cell loss rate, we began to care about their own battery, how to view the cell loss rate? Open the 360 security guards, function Daquan "found" 360 hardware guru, running directly through the hardware detection button in the battery information query to the loss rate of the notebook battery (Figure 1).
Figure 1: In the 360 hardware guru, check the battery wear and tear360 security experts said that Under normal circumstances, the new cell loss rate is relatively low (usually below 5%), while the old battery loss rate is usually higher, even more than 50%. The loss rate is higher, battery life will be the worse.Tips: With the 360 hardware guru battery detection, there is a scientific reference to the optional battery, will not be profiteers shoddy, the old charge fooled. The experiments show that the spread of the Internet batteries refrigerator repair method is nonsense, there is no scientific basis.Computer hardware is subject to monitoring, and better safety performanceThe same computer equipment, some people can use, while others with less than six months on the bad, the difference in habits. Security experts say that the summer, the heat of the computer is normal, CPU, hard disk, motherboard, memory and other hardware is working at normal temperature, if more than the standard temperature, should do a good job cooling measures to prevent damage to the hardware device.Directly monitor all major hardware, operating temperature 360 hardware guru, if straight over the standard will be a red warning is displayed (Figure 2).

The company uses an innovative "cloud security", launch the Internet users to participate in its inception, rogue software and Trojans, the plug-fatal blow, which won the 360 Internet users and the market.
