Rumors of a laptop battery: a new battery charge and discharge cycles should be a way to activate battery performance.
Truth: This argument is not exactly a rumor. Because certain notebook batteries from the product in the hands of the customer will be after a certain period of time, is short of one month or as long as six months. For the longest time, the battery factory, its electrode materials will be passive, so the first time on the computer manufacturer suggested initial charge of battery is best for 3 to 5 when fully loaded and processes discharge to eliminate passivation of electrode materials to achieve maximum capacity. However, the prosecution and defense are talking about does not mean that the depth of discharge, but a shallow discharge. There is a laptop battery charging time to grasp a problem, you can go to the client network adapter Pai to inquire about the battery.
Rumor Battery Laptop 2: When a new battery to buy later, the general will agree that: The best of three times the battery charge and discharge cycles, and the laptop battery time load discharge should not exceed 12 hours to enable maximum efficiency of the battery.
Truth: Ni-MH battery to reach saturation, the more perfect, need to go through “complementary” and “netting” process, this time, generally about 5 hours. Currently, lithium-ion “constant” “constant voltage” charge feature is its deep cool control to 4 hours. Once completed, the circuit protection Internal battery automatically stops load, if this approach is unscientific and has no practical significance.
Some people have been tested using a mobile phone: in using the charger Travel charger battery is full, the passage charger battery charger to confirm the degree of saturation. When he discovered charger charger recharges the battery still, they think that the battery has not yet reached saturation. In fact, this lack of rigorous testing methods. The reason is that the LED is not detected Charger Charger saturated or not, the only correct reference voltage charger cellphone charger does not necessarily reference voltage, so when the phone battery reached Charger Charger May did not think the pricing yet, but it is filled, the only of its own knowledge. So we charge in accordance with the requirements of the specification can be, and prolonging the time to recharge laptop battery is just waste of time unnecessarily.
Rumor Battery Laptop 3: As long as laptop batteries are used properly, it will be within a certain period of movement seems best to achieve the maximum capacity. For example, early-nickel metal hydride, batteries nickel cadmium, if used properly, regular maintenance will be paragraphs 15 to 203 total cycles to reach its maximum capacity (plant capacity 1200mAh Ni-MH battery in the loop 120 times, the capacity may be to 1200mAh).
The truth: This is a battery in the Japanese products are more common technical specifications in the cyclical nature of the work, often seen in Fig. However, the current lithium-ion battery, the phenomenon of peak cycle does not exist. Because lithium-ion battery factory scrap, with performance capacity less for circle time, never had the rebound capabilities. Maybe have a friend who will ask a few users of ThinkPad notebooks with the release depth, you can restore the battery capacity. In fact, it tests only detect single software error, the actual capacity of the battery does not improve. The right factor laptop battery laptop battery is the temperature of their environment, of course, the laptop charging time there is a certain relationship, but still below the environment. Lithium-ion batteries at the end, there is no better state? The answer is yes, he has suffered with the change of temperature. Under normal circumstances, lithium-ion batteries in 26 ℃ ~ 41 ℃ environment to show excellent performance. For low temperature or high temperature conditions, its performance is reduced. For example, according to your outdoors in bright sunlight using a laptop case, it is more in domestic use.
Rumor Battery Laptop 4: 2 rated capacity of the same family (eg, 800mAh) batteries, if an actual measured capacity 860mAh, 805mAh the other, so 860mAH is definitely better than the 805mAh.
Truth: In general, the different models (different formats) and lithium-ion battery, the higher the capacity of the time used. If you put aside factors such as size and weight, of course, is the capacity the better. But for two nominal capacity of the same family (eg, the example above) the battery may not be. Since the real high capacity battery that can be added in the electrode materials used to increase the initial capacity of the material, which reduces the stability of electrode materials used. The result is shown in dozens of cycles, after the rapid decomposition of spare high-capacity, while capacity is still weak, strong. Many domestic enterprises to reduce costs and increase sales, often use these tools to produce high-capacity batteries. Users will find that six months after the use of working time is much shorter. In short, to improve capacity at the expense of sacrificing the life cycle, the battery manufacturers are not significant top and bottom of the article, it is impossible to truly improve the capacity of the battery.
Laptop battery rumor 5: If you do not use rechargeable batteries, should shine with the Re-save power.
The truth: Actually, not just the rumors mentioned above, lithium-ion batteries at the end, which was full of canned or preserve the luster is sure to make a lot of people confused? Answer to this question from a congenital defect of their talk, which is “aging effect.” Lithium-ion battery in storage for some time, even without the use of recycled materials or some of its capabilities will be a permanent loss because the lithium-material ion battery anode plant is started when the failure of their journey. Different temperatures and the saturation level of the range is also different under the age of specific range can be seen in the table below.
Thus, the higher the storage temperature, the battery of more comprehensive, the extent of capacity. So for long term storage of lithium-ion batteries, the user must be controlled to 40% of its electricity and stored at 15 ℃ or lower temperature may be. For those nickel-metal hydride batteries and nickel-cadmium batteries are not in this “aging effect”, after the long-term storage in just a few full charge and discharge can be restored to its original capacity.
Rumors laptop battery 6: cooldown laptop battery are generally controlled, for the laptop battery is full then, while continuing to charge the battery 1 to 2 hours, thereby helping to increase the saturation of the battery.
The truth: Actually, the laptop battery today is generally a circuit power protection, full power after the protection circuit the battery will automatically cut the load circuit. Therefore, the charging time of battery cell is a fixed value, filled with the battery after the power only for mobile devices, even if the battery for 12 hours and then it is useless.
