Laptop battery charging time to pay attention, in the end the number of notebook battery Laptop Battery charge time is right, in the process of charging what we have to grasp? How many hours will it affect the laptop battery life? The following extensions on these issues open, take a look at the most vulnerable for the notebook notebook what could be attention.

Laptop Battery Charge Time

Rumors that one: the activation of a new battery

A new battery charge and discharge cycles should be a way to activate the battery performance.

Truth: This argument is not a rumor exactly. Because some laptop batteries from the product to the customer's hands will be after a certain time lag, the short is a month, as many as half a year. For longer battery life time difference, the electrode materials will be passive, so the manufacturer's suggested initial use of battery is best for 3 to 5 times fully charge and discharge processes in order to eliminate electrode materials passivation, to reach maximum capacity. However, here is the IBM 02K7039 Battery
IBM ThinkPad X60 Battery general charge and discharge is not a depth of discharge, but a shallow discharge, where there is a laptop battery charging time to grasp the problem.

Laptop batteries "before the three" charge

Rumor 2: When a new battery buy it back later, people would generally say the best three times charge and discharge cycles, while the laptop battery discharge time should not exceed 12 hours in order to activate the battery maximum effectiveness.

Truth: Ni-MH battery in order to achieve the most perfect saturation, need to go through "complementary" and "trickle" process, this time, generally about 5 hours. At present, lithium-ion batteries, "constant", "constant voltage" charging feature is its deep-charge time control at 4 hours. Once filled, the internal laptop battery protection circuit will automatically stop IBM 02K6620 Battery charging, so this approach is unscientific and has no practical significance.

Some people have been tested with the mobile phone. Using the battery charger travel charger is full, the switch to Charger battery charger to confirm the degree of saturation. When he discovered Charger charger is still charging the battery, they think that the battery has not yet reached saturation. In fact, this lack of rigorous testing methods. The reason is that the indicator light is not detected Charger Charger saturated or not, the only true standard of reference voltage charger Charger cell phone does not necessarily mean reference voltage, so when the phone that the battery reached, Charger Charger may not think so, still charging, but is filled in, the only of its own know.

As long as the laptop battery charge IBM 02K6928 Battery time, discharge time to grasp properly, it is possible to reach the best condition

Rumors 3: As long as rechargeable batteries used properly, it will, within a certain period of circulation appears best to achieve maximum capacity.

For example, the early nickel-metal hydride, nickel cadmium batteries, if used properly, regular maintenance, will be 15 to 203 cycles points to reach its maximum capacity (factory capacity 1200mAh Ni-MH battery in the loop 120 times, the capacity may be to 1200mAh).

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

The right laptop battery laptop battery factor affecting the environment in which the temperature, of course, laptop charging time there is a certain IBM 02K6651 Battery relationship, but still inferior to the environment.

Lithium-ion batteries in the end there is no best state? The answer is yes, it suffered with the ambient temperature change. Under normal circumstances, lithium-ion batteries in 26 ℃ ~ 41 ℃ environment would show excellent performance. By low temperature or high-temperature state, its performance is being reduced. For example, according to your outdoors in direct sunlight using a laptop computer cases, there is no longer in the indoor use.

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 definitely better than the 805mAh.

Truth: In general, different models (different sizes) and lithium-ion battery, the higher the capacity the longer the time used. If you set aside such factors as size and weight, of course, is the capacity the better. But for two nominal capacity of the same (for example, the example above) the battery may not be. Since the actual high capacity battery that is likely to add in the electrode materials used to increase the initial capacity of the material, reducing the stability of electrode IBM FRU 92P1137 Battery materials used. The result is shown in dozens of cycles, after the rapid decay of high capacity piece, while the capacity is still low strong. Many domestic firms in order to reduce costs and expand sales, often on the use of such tools to produce high-capacity battery. 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 cycle life, manufacturers are not the material up and down laptop battery article, it is impossible to truly improve the laptop battery capacity.

The preservation of laptop battery

Rumor 5: If you do not use rechargeable batteries, should shine of the electric re-save.

Truth: In fact, not only are the above-mentioned rumors, notebook lithium-ion batteries in the end that was full of preserved or preserving the shine is sure to make a lot of people confused? Answer to this question from a congenital defect of their talk, that is "aging effect." Lithium-ion battery in storage for some time, even without the use of recycled some of its capacity will be a permanent loss, because the lithium-ion battery anode material from the factory is started when the failure of their journey. Different temperatures and the saturation level of the range is also IBM FRU 92P1141 Battery different under the age of the specific range can be seen in the table below.

Thus, the higher the storage temperature, the battery charge of the more full, the greater the magnitude of capacity. So for long-term preservation of lithium ion batteries, the user should be controlled at 40% of its electricity and stored at 15 ℃ or lower temperatures can be. For those nickel-metal hydride and nickel cadmium batteries did not exist in this "aging effect", after the long-term storage in just a few full charge and discharge can be restored to its original capacity of the follow-up full of electric charge

Rumors 6: laptop battery recharge time is generally controlled, for the laptop battery IBM FRU 92P1139 Battery is full then, while continuing to charge the battery charge 1 to 2 hours, which would help to enhance battery saturation.

Truth: In fact, today's notebook computers notebook batteries are generally over power protection circuit, full of points, then he will automatically cut off the charging circuit. Therefore, charging time is fixed, full power only after the laptop power supply equipment, real-time laptop battery re-charge 12 hours to no purpose.
