DELL UW280 Battery charging time as long as the discharge time to grasp properly there may be at their best Rumor three: as long as rechargeable batteries used properly, it will cycle within a certain period there best to achieve maximum capacity.

Such as early in the nickel-metal hydride, 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 DELL GR997 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 charging time there is a certain relationship, but still inferior to the environment.

    Lithium-ion DELL FP269 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.
