A new battery charge and discharge cycles should be a way to activate the battery performance.
Truth: This argument is not a rumor exactly. The battery from the factory to the hands of users laptop battery there is a time lag, the short is one month or as long as six months. 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. But usually manufacturers have not paid enough attention, reminds consumers that a full charge and discharge referred to here should not be the depth of discharge, but should be controlled at 5% to 8% can. Otherwise, a new battery is likely to be scrapped.
■ "The first three" charge
Misinformation 2: When a new battery to buy back later, preferably three times charge and discharge cycles, charging 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 battery's internal protection circuit will automatically stop charging, so this approach is panasonic CGR-D08 battery 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.
■ best
Misinformation 3: As long as rechargeable batteries used properly, it will, panasonic NV-DS30 battery 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 10 to 200 cycles points to reach its maximum capacity (factory capacity 1000mAh Ni-MH battery in the loop 100 times, the capacity may be to 1100mAh).
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 mainstream of current 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 battery's actual capacity did not improve.
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 25 ℃ ~ 40 ℃ 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.
■ Capacity
Misinformation four: two nominal capacity of the same (for example, 800mAh) batteries, if an actual measured capacity of 860mAh, panasonic PV-BP17 battery 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 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, battery makers are not material up and down the article, it is impossible to truly improve the battery capacity
■ Battery Save
Misinformation 5: If you do not use rechargeable batteries, should shine of the electric re-save.
Truth: In fact, not only are the above-mentioned rumor,panasonic VW-VBD210 battery 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 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.
■ Follow-up full of electric charge
Misinformation 6: to charge the battery when the electrical impulse is full 12 hours later adjourned to the charge, this is conducive to increasing the battery saturation.
Truth: Under normal circumstances, a quality and qualified Charger charger will automatically shut down after the completion of charging charging circuit, panasonic CGA-DU21 battery there is no current, even if the battery in the Charger to place 10 hours of no avail. At present the vast majority of cell phone chargers are sampled such a design. Thus, when the green indicator light, direct use of the battery can be brought down
