laptop maintenance ultimate guide
for the performance and functionality of a laptop, vendors are constantly producing powerful, system stability of portable, hardware design, more humane, however high one laptop battery performance and uses are often ignored by the user, if a problem occurs when the battery used to care about its use and maintenance problems. Laptop battery needed to enhance the use of concepts, not much samller, to purchase a new battery. In order to allow laptop owners are able to better understand all aspects of laptop batteries, I will share their experiences with you. After all, laptop battery prices are very expensive, accounted for notebooks 10% per cent of the overall price, batteries can be considered consumer goods, using the good battery is equal to saving money.
Notebook battery
Notebook battery of category and material:
notebook computer using of battery main min four species: 1. Nickel chromium battery [nickel cadmium Ni-Cd], and 2. nickel hydrogen battery [nickel hydrogen Ni-MH], and 3. lithium battery [lithium battery Li, and lithium ion Li-ion, and polymer lithium second times Li-polymer], and 4. fuel battery [alkaline FC (AFC), and phosphate type FC (PAFC), and melting carbonate FC (MCFC), and solid oxides FC (SOFC) and the proton exchange film FC (PEMFC),]
nickel cadmium battery (Ni-Cd)
first of notebook computer are is using nickel cadmium battery (Ni-Cd), because then battery technology enough advanced, therefore nickel cadmium battery has many was headache of shortcomings, as: volume large, and weight heavy, and capacity small, and life short , Have memory effect (to my impression is no shichu). The pursuit of these is undoubtedly the notebook runs counter to the light, fast performance. Nickel-cadmium batteries have now been eliminated, the notebook also break and nickel-cadmium, then mention it there is not much of a need.
nickel-metal hydride battery (Ni-MH)
nickel-hydrogen batteries are by far the most environmentally-friendly batteries, focusing on environmentally-friendly countries are strongly encouraged to use nickel-metal hydride battery as easy to recycle, and the destruction of the environment is minimal. However compared to nickel-metal hydride battery and lithium battery, there are a few disadvantages. Long charging time, more sink, weight capacity is smaller than the lithium battery, also have memory effect. The memory of it, while not as large as nickel-cadmium batteries, but I still need to discharge, the user must be exhausted before charging. But nickel-hydrogen battery charge up to 700 times more than some good quality products of charging and discharging of up to 1200 times, live longer than lithium batteries and the price is also very popular.
lithium batteries (Li), lithium-ion batteries (Li-ion), lithium polymer secondary lithium-ion battery (Li-polymer)
Li
Li long ago had, at that time when using less secure, often charging occurs when combustion, burst, this may be because lithium is too active account. Later there will be a modified lithium-ion battery (Li-ion) joined the inhibition of lithium active ingredients, it is a lithium battery replacement products, its anode carbon used to occlude lithium ions, discharging dell vostro 2510 battery, lithium lithium-ion, from the battery anode, reach the cathode of lithium-ion battery. Charging, lithium atoms ionized lithium ions and electrons in the cathode and lithium-ion anodal mobility and electronic synthesis of lithium atom. Discharge, lithium atoms from graphite anode surface ionization within the Crystal lithium ions and electrons, and synthesis of lithium atoms at the cathode. Therefore, in the lithium battery lithium-ion form forever, will not occur in the form of lithium metal, of course, also burning, danger of explosion does not occur. Lithium ions move between anode and cathode, electrode itself does not change. This is the difference between lithium-ion batteries and lithium batteries are essentially. So that the battery really achieve a safe, efficient, convenient, and eliminated the old battery. Method of distinguishing between them is quite simple: from the battery of the logo on recognition, identified as Li of the lithium battery, lithium-ion battery Li-ion.
secondary lithium polymer lithium ion battery (Li-polymer) is said in the three main building in at least one or more systems with polymer materials as the main battery. In terms of shape, lithium polymer secondary lithium ion batteries has thin, can be of arbitrary size and can be of arbitrary shape and many other advantages, so you can meet the needs of product, made into any shape and capacity of the battery. In terms of thickness, lithium polymerSecondary battery thickness of about 2~4mm, and lithium-ion battery is the minimum thickness of 6mm, you can at least reduce the thickness of about 50%, you can achieve the minimum thickness of approximately 0.5mm.
now the so-called lithium battery of the notebook and mobile phone use, in fact, the lithium-ion battery. Lithium-ion batteries with other battery cannot compare advantages: high working voltage; small size, light weight, high energy; security fast charge; allow wide temperature range; small, recalling the effects of small discharge current (now some notion that lithium ion batteries have no memory effect, this is not responsible for claims), no environmental pollution, and so on. Lithium-ion batteries also have their own shortcomings, of course Dell latitude d830 Battery, that is, high prices, charging times less (its charge and discharge times only 400-600, specially improved products zxcsky32645 but also more than 800 times. Calculated according to the charging once a day, best lithium batteries but more than two years out of work. ) Dell Vostro 2510 battery, And dry batteries no interchangeability, operating voltage variation, discharge rate, capacity declined quickly, not large current discharge.
fuel cell
fuel cell
fuel cells [alkaline FC (AFC), phosphoric acid-FC (PAFC), molten carbonate FC (MCFC) FC, solid oxide (SOFC) and FC proton exchange membrane (PEMFC)] is a chemical battery, it use of substances chemical reactions release energy, transform it directly into electricity. From that point of view, it and other chemical batteries, such as manganese dry batteries, lead-acid batteries are similar. However, which is required for it to work continuously to supply active substances (substances react)-fuel and oxidizer, these and other general chemistry battery is not the same. Because it is the fuel through chemical reactions release energy into electric energy output, so called fuel cells.
six-cell battery
for inside and outside of a laptop battery power and principle there is a certain degree of understanding, we can better use of laptop batteries in daily work and daily life. Next turn to the author for notebook computer battery used in some of their own experience and suggestions.
first get a new battery, many users of practice is to follow the tip in the lithium battery business using three charge 12 hours or more before. Online there are many arguments, but I found in actual use, in fact, the most is not necessary for laptop batteries. Why? Businessmen said this was done in order to fully activate cell activity, new batteries fully awaken. Sounds like the reason is very full and credible, but you have not thought of that problem. If the laptop batteries also played without is fully activated by manufacturers so that products can say only one of SKD/case. Cannot require each user to master activated battery of techniques, will not be possible in reality. Therefore, in front of the battery factory has been a manufacturer of fully activated. So called user charge 12 hours to the battery's use? Here I give a negative answer Ibm Thinkpad T500 Battery, notebook batteries are currently charging management system with sophisticated power management circuits, and, after when the batteries reach saturation, control circuit automatically switch to a short status, so the next time is just a waste of time. How to activate cell activity then? In fact, manufacturers for cell activation is the absence of overload protection battery charge and discharge for a long time. Therefore, charging three times before 12 hours is not necessary.
in the second, many users in the use of batteries is confused, should wait until the battery is completely drained before recharging. Must respond to that question is that, if you can do so is certainly a good thing, but if you don't bother. I of course entirely in this context does not refer to excessive discharges, practice shows that excessive discharge is definitely harmful to the battery, it will shorten the battery life. So when notebook tips lower power can be charged in a timely manner. Some businesses repeatedly stated their own lithium-ion batteries have no memory effect, this is a very irresponsible approach. So when your battery is when more power is still not charging for good, because the memory effect is real.
storage temperature 40% charging State 100% charging State
0 of 98% (a years yihou) 94% (a years yihou)
25 of 96% (a years yihou) 80% (a years yihou)
40 of 85% (a years yihou) 65% (a years yihou)
60 of 75% (a years yihou) 60% (3 months yihou)
(percentage for then of saturation relative initial value of percentage)
course , Best to take out the battery once a month, can guarantee good save state of the battery, and not let the power loss and damage the battery completely.
IV, in the instructions for use of a laptop "use should be fully charged in a month-and-drop" approach is necessary. Lithium-ion battery for laptops generally with chip and charge management controller chip. Managing the chip has a series of registers, there is a capacity, temperature, values such as ID number, charge status, discharge. These numbers will gradually change in use. Personally, I think, in the instructions for use of a laptop "use should be fully charged in a month-and-drop" approach in the main role should be the correction of these registers incorrect values, makes battery battery charge control and the nominal capacity of anastomosis in reality. This work cannot be omitted, after all, the high price of notebook is also effeminate: a noble.
last in use to talk about, how to make laptop batteries for longer. Since you bought your notebookWhether you want to use it, the battery is one of these consumables will inevitably continue with using time and towards the end. How to make laptop battery life more longer? Power saving technology? Sleep? Hard hang? Reduce screen brightness? Various methods seems to increase the so-called extension of the time. But have you ever wanted to, so does it make sense to extend the time of? I open the laptop does not run any program, not open display, does not let the hard disk, and I cannot achieve more time. Think this is absurd, the notebook is to use, not high-sounding furnishings. Therefore I suggest that you use notebooks instead of worrying about how to use the notebook. Perhaps, after two years of the notebook market is another world, your laptop to the ranks of the retired. As long as the fact that the daily habits of the battery, normal use of the battery, it may not need to show.
