Dell Inspiron 9400 battery performance is related to laptop battery life, this is generally more important for businessmen; they often need to take a laptop for mobile office applications such as conferences or business meetings. For the general consumers, most at ordinary times is to use the Dell Inspiron 9400 battery supply is connected, so for the selection of the battery and maintenance is less concerned about, so that the notebook to use after a period of time, battery life is greatly reduced, it is difficult to deal with some emergency. An overview, Dell Inspiron 9400 battery Dell Inspiron 9400 Laptop equipped with battery is nickel cadmium battery, the earliest but the battery has a "memory effect", before each charge must discharge, use rise is not very convenient, and the battery have big volume, heavy weight, small volume, short service life and so on shortcomings, so has been abandoned by the market. Then the nimh batteries, but the battery also has a "memory effect", so also gradually being eliminated by the market. At present, the market is the mainstream in the lithium battery and lithium polymer batteries, including lithium ion battery has small volume, light weight, large capacity, low memory effect, and the advantages of charging time is short, so it is used by merchants a lot. The lithium polymer battery with high energy density, miniaturization, ultra-thin, lightweight, and high security and low cost, and other obvious advantages, is a new type of battery. Second, the Dell Inspiron 9400 battery usage skills Reasonable use of Dell Inspiron 9400 battery is to extend battery life, an effective means of battery maintenance. Many users of laptop batteries use time long, can appear rechargeable dissatisfaction, reduced endurance, obvious aging phenomenon. Therefore, you should pay attention to when using Dell Inspiron 9400 battery a few tricks, and to avoid some misunderstanding. Next, the author will introduce some laptop batteries using techniques and the attention of the problem. 1, the Dell Inspiron 9400 battery charge for the first time Many consumers when buying a laptop, dealers will be informed that a new notebook to repeated three times to the battery fully charge/discharge, charge time in more than 12 hours, best for the activation of the battery. This sentence, make the broad masses of the user to enter a myth. In fact, the laptop to activate the battery before leaving the factory, in order to avoid the loss of natural affect battery life, will remain a small amount of electrical energy. So users get the notebook is has been activated, according to the dealer to do again, laptop batteries after complete a full charge will automatically stop working, and there is no need to keep the charging time to not only 12 hours, and to do so but also increase the loss of the battery. In general, new laptop just use according to the normal charge/discharge manner can. 2, deliberately run out of electricity Regularly with photovoltaic power, about a month to a, in order to ensure full charge. To fully use of photovoltaic power, just get a laptop running a large amount of CPU tasks, such as some large type 3 d games, or watching high-definition video, so can use the electric energy in the battery soon, of course, don't forget to unplug the power when you do this. Of course, every time before charging the battery discharge is not necessary, and it is harmful. The practice proved: the depth of the battery discharge will be meaningless to shorten the service life of the battery, so suggest that in general, when the battery use by about 10% when can recharge the battery. But when the battery is still in the 30% to the power on the best or don't charge, because the memory effect does exist. 3, don't have to take down the Dell Inspiron 9400 battery when the power supply is connected Many users are confused, when plug in the ac, do you want to take down the battery, in order to prevent the repeated charge and discharge? It is not necessary. Because now most of the laptop power supply control circuit design of a sex, is when the battery is less than 90% or 90% when charging, and achieve the capacity through natural discharge time is 2 weeks to a month. And even if the battery is charging again, losses also won't than for a long time without the battery caused by the loss. At the same time, if the user in operating notebook when suddenly loses power, not only has damage to the laptop, and data loss is irreparable consequences. Dell Inspiron 9400 battery
