Rumors of a laptop battery charging time

Laptop battery charging time to pay attention, in the end the number of laptop battery is the right time? In a notebook battery charging process, we need to grasp what? Laptop battery for long battery life will affect it? The following extensions to open on these issues, see the most vulnerable for laptop notebook battery have anything to attention.


Rumors of a laptop battery charging time: ---- new battery new battery activation charge and discharge cycles should be a way to activate battery performance.

Truth: This argument is not exactly a rumor. Because some laptop batteries from production to the customer's hands since there will be some time lag as short as one month, as many as half a year. For longer battery time difference, the electrode materials will be passive, so manufacturers recommend the initial use of the battery is best for 3 to 5 times fully charge and discharge processes in order to eliminate electrode materials passivation, to reach maximum capacity. But the general discharge is not here, the depth of discharge, but the shallow discharge, where there is a laptop battery charging time to grasp the problem.

Laptop battery charging, "The first three" rumor II: When a new battery to buy back later, usually three times that the best charge and discharge cycles, and laptop battery charge and discharge time should be more than 12 hours, in order to activate the battery maximum effectiveness.

Truth: Ni-MH battery in order to achieve the perfect saturation, need to go through "complementary" and "trickle" process, this time is generally about 5 hours. At present, lithium-ion batteries "constant", "constant" charge characteristics is to control the depth charge time 4 hours. Once filled, the internal battery will automatically stop charging protection circuit, so this is not scientific nor practical significance.

Laptop battery charging time as long as the discharge time to grasp properly, there may be three to achieve the best rumor: as long as the laptop batteries used properly, will be within a certain period of circulation appears best to achieve maximum capacity. Such as early nickel hydride and nickel cadmium batteries, if used properly, regular maintenance, will cycle from 15 to 203 points to reach its maximum capacity (factory capacity 1200mAh Ni-MH battery in the loop 120 times, the capacity may to 1200mAh).





Truth: It's a battery in the Japanese products are more common in the technical specification of the cyclical nature of the figure usually seen. However, the current mainstream lithium-ion battery, this cycle peak phenomenon does not exist. Because the lithium-ion battery from the factory to the scrap, the performance of its capacity a little time for the loop, never had the capacity rebound phenomenon. Maybe a friend will ask some of the ThinkPad notebook users to deep discharge, you can restore the battery capacity. In fact it is only testing the software error detection only, the actual capacity of the battery did not improve.

The right laptop battery laptop battery impact factor is the temperature of the environment in which, of course, laptop battery charging time there is a certain relationship, but still inferior to the environment.

Lithium-ion battery in the end there is no best? The answer is yes, it suffered with the ambient temperature change. In general, lithium ion batteries in 26 ℃ ~ 41 ℃ environment would show excellent performance. And by the low or high temperature state, its performance is being reduced. For example, you direct sunlight outdoors using a laptop computer cases, there is no longer used indoors.

Notebook battery capacity rumor four: two nominal capacity of the same (for example, 800mAh) batteries, if an actual measured capacity of 860mAh, the other is 805mAh, so 860mAH's certainly better than the 805mAh's.

Truth: In general, the different models (different sizes) of the lithium-ion battery, the higher the capacity the longer use. If the size and weight and other factors aside, of course, the higher capacity the better. However, the same for the two nominal capacity (for example, the above example) may not be the battery. Because the actual high capacity battery that, probably added in the electrode material used to increase the initial capacity of the material, reducing the stability of the electrode material used. As a result, dozens of the loop on the performance after the rapid decay of high capacity piece, while the capacity is still low strong.
