Laptop battery guide
1, laptop battery replacement
As people demand more and more mobile, notebook surge in sales in the past two years, laptop battery and increasingly thin, easy to carry. However, the mobile office is not only required the lighter the better laptop, its battery life determines whether you can successfully complete its work. The popularity of Centrino technology, making the current mainstream notebook standby time has reached 3-4 hours or more, can basically meet the needs of a half-day work. If you are only the notebook as a desktop machine to use, then the battery may not be concerned about. But with the popularity of wireless Internet access, limiting computer also only the power cord, in which case, using battery-powered chances greatly enhanced. However, the rechargeable battery is not a once and for all, its life will be based on charge and discharge times to decide. In the secondary market, the most criticism is the battery aging. Once the laptop loses battery, it becomes a mobile PC, worth plummeted, and inconvenient to use, I have a lot of close friends have been troubled by this problem. Under normal circumstances, the normal use of the laptop, in almost two years later have to face the battery problem, but at this time to ensure good notebook itself, configure enough to use. If the change sets a new, of course, huge waste; Well, the problem how to solve it? Currently we have four kinds of conventional ways to evoke the old books new life: purchasing a new battery; to buy compatible batteries; their replacement batteries; to buy an external lithium battery. However, speaking of these four methods have advantages and disadvantages, such as the original battery expensive; compatible batteries are also worried that the quality was not guaranteed; replacement batteries danger great; external lithium battery to bring inconvenience and so on. So for different users, HP 510 Laptop Battery which are several ways how to choose, how to avoid risk?
2, battery life, capacity, power in the end with whom the
Now the laptop battery laptop battery manufacturers have a more detailed description, we often can see the “six-core 4400mAh”, “4-pin 2200mAh” nominal value such as batteries, Acer Aspire 3000 Laptop Battery over time, we believe that directly determine the capacity of 4400mAh or 2200mAh Notebook working hours. With common 2200mAh, 3.6V batteries, for example, could have used some small way the composition of four batteries in series, their voltage is 14.4V, Capacity 2200mAh. Many 14-inch notebook, you might use 2 and 4 strings of 8-cell hybrid mode, the voltage remains at 14.4V, capacity doubled to reach 4400mAh, to ensure a longer usage time. However, the same is a 2200mAh, 3.6V batteries, if we adopt the 2 and 3 strings of 6 cores hybrid approach, its battery capacity it will still be 4400mAh, voltage down to 10.8V, if we just look at capacity, its use of time should be, and 8 the same cell battery. However, the 8-cell battery, after all, two more batteries, which are a waste it? It should be noted, when we talk about computer power consumption, the total nominal power use, rather than a simple yes-current. Sony pcga-bp2s Laptop Battery power should be multiplied by current, voltage, such as the previously mentioned 8-cell lithium battery, the power should be 63.36Wh, 6 cores for 47.52Wh, 4 cores for 31.68Wh. If according to this value, 8-cell lithium battery advantage reflected. The vendors nominal standby time, is derived by the following formula: The battery power (WH) / Notebook standby power consumption (W) = Standby time (h) such 63.36Wh 8-cell lithium battery, with power consumption in standby for the 10W notebook and come standby time is approximately 6 hours. However, in theory, in reality, they are not that simple. We all know that any energy efficiency has a problem, the battery is no exception. High-voltage battery, its efficiency is relatively low, even if the same total power, its use of time than low-voltage high-current battery short, we now have introduced a number of vendors have begun high-volume low-voltage battery (more parallel, less in series) to ensure that Notebook longer standby time, while the battery is almost no increase in cost. In short, both Wh or mAh, can not very intuitive manifestation of battery time, IBM ThinkPad R40 Series Battery and most manufacturers like to mark mAh, and will not cause too much confusion. Only in the purchase, you need more comprehensive consideration of many factors.
3, laptop battery more errors
Lithium batteries need to deep discharge: Obviously, for a memory effect of nickel-metal hydride batteries, the full full release will increase efficiency. However, there is no memory effect lithium batteries can be used at with the red, does not affect their capacity. When using an external power supply, it is best unplug the laptop battery: This paper presents this view is based on frequent charging and discharging may damage the laptop batteries, but does not know that do more harm than good. On the one hand, and now comes with smart Li-ion battery protection circuit, generally when the electricity when a drop of 5% or more will only start charging; the other hand, frequent plug the battery, may result in interface being exposed, but damage to the battery and notebook; and finally, Laptop Battery UPS has also played the role of a sudden power outage, the battery can guarantee that your computer continues to run, otherwise you will suffer some losses. The first charge should be 12 hours: After buying notebooks, sales staff will advise the you, the first charge should be 12 hours or more, aim is to “activate” the battery. In fact, now the majority of laptop battery with over-power protection circuit, as long as full point, the battery on the cut off contact with the AC at this time to “recharge” effect can only be a waste of energy and not a long time, Dell Inspiron 6000 Battery lithium batteries should be empty (full) power to save: This is the two diametrically opposite conclusion, but there are people who support. Said air power saved on the grounds that lithium batteries will slowly discharge, affecting life, and if air power, you do not have to worry about discharge. Said that full power saved on the grounds that since the lithium battery will discharge, if there is no electricity, it will definitely affect the life, just like people hungry after a fire, it will harm the body. In fact, these two arguments are not correct, and if you are a long time do not use lithium batteries, should be 60% of its capacity to save, this state, the battery discharge is relatively slow, and can be stored for long periods often do not charge and discharge of lithium batteries Impact: This view is also a one-sided, although there is no memory effect from the battery, but the frequent charge and discharge, or have an impact on life in general as far as power consumption less than 10% after the re-charging of battery life is conducive to growth. But if there are special needs, and occasionally advance charge, its impact will not be too much. In addition, try not to heat, cold environment, the use of batteries, which will affect its life. Some of the above to avoid errors, but also help to enhance battery life and, of course, the most important thing is when there is power to reduce the frequency of the use of batteries, so we need to purchase, repair the chances of the battery is greatly reduced.
