The truth about laptop battery
This is one of the most important and least understood of it causes your notebookand so many questions unanswered. Why laptop battery gradually lose their ability to hold a charge? Why it takes longer to load a laptop to go 80 to 100 percent load than it takes to go from zero to 80 percent? What is the difference between a three-cell and a six-cell battery? Rather than shrug their shoulders for another day, we asked for answers from two experts, Matt Kohut, an analyst at worldwide competitive Lenovo and John Wozniak, Ph.D. Distinguished Technologist at HP.
MOBILE: At what point in the lifecycle of a standard laptop battery Dell Inspiron 6400 battery last longer?
Kohut: The industry average is about 30 percent per year degradation. You'll probably start noticeable after about six months.
John Wozniak: Batteries tend to fade quite rapidly during the first 10 or 20 cycles, then levels capacity off.
How long does a typical battery last?
Kohut: Approximately 350 charge cycles. A cycle is the use Cumulative who reached 70 percent degradation, or seven times while 90 percent of the battery capacity was used.
What causes a battery to lose capacity over time?
Wozniak: Think of a battery that has pores, where the electrons move between the cathode and anode. When the pores are clogged, you can not move the electrons as effectively over. Then, lithium is associated with a side or the other, and it no longer contributes to the movement of electrons. It is saved.
Do you need to build a memory battery, or a condition is to obtain the best performance?
Kohut: This was the case in the days to the lithium-metal hydride, however, with a standard lithium-ion battery, just make sure you charge the battery fully. Most battery manufacturers ship with a load of 80 percent.
Air conditioning, which means the battery drain from the battery to zero, then fully recharge it while Windows monitors, resets curve. It does not extend the battery life, but it improves the accuracy [Battery Monitor]. Over time, the excesses of precision in the program Windows that measures battery life. That's why he can say that you suddenly went from 80 to 20 percent in five minutes. c
How can you trust the state of charge that gives you Windows?
Kohut: If the battery full reports, Windows says it is full. Windows periodically checks the battery, but it is more of a thumbs-up/thumbs-down a true assessment. Windows is gross, is confidence, if his full confidence the hypothesis where the vacuum. But know that it doesn't have the communication that the battery degrades over time. We recommend that the Lenovo Power Manager, because it much more resourceful. He knows the status of each individual cell, so its balanced, unbalanced load, no load, etc.
John Wozniak: If the BIOS is written correctly, Windows is really accurate within 1 to 2 per cent. The problem is how it updates often.
When you load a laptop, why does the last 5 to 10 Percent of taking more time than the first 85 to 90 percent?
Kohut: If the battery is low, we'll charge it to a faster pace. But when the battery fills up, we go back, because it is the last piece load that causes problems of form. Other vendors who charge more rapid decline in the last 10 percent. Dell, for example, does not load fast pedal for metal, from zero to 80 percent. Then back off and coast into the finish line. Lenovo starts fast, but lost more and more through whole load. This allows a more uniform rate of charge. It takes more time together, but it contributes to longevity batterys.
Some laptops not commence charging unless the battery is below a certain level, say, 95 percent. Why?
Kohut: it loads to 100 percent each time cycles adds battery may wear out faster. In the typical situation of the office, you're hooked up to 100 percent every day. Then you take home and plug it in again, after losing perhaps only 2 percent. If you load to 100 percent higher, you begin to add cycles that the battery wear out because you're launching a full charge cycle. The idea behind this process is that if the battery is below a certain percentage, not the stress of the load.
How important is the number of cells in determining the battery capacity?
Kohut: The three, six, nine single-cell battery is a shorthand to explain how Dell Inspiron 1520 Battery life of a machine, but hours watt-hours to determine capacity. The average consumer has no idea that a battery nine cells around a 84-watt-hours of energy, they just know it's a nine cells. One of the two competitors Lenovos batteriesa six-cell 53-watt-hour and 47-watt-hour. The second does not provide the same capacity. To understand how much power a battery will hold, you need to consider the watt-hours.
Some vendors advertise battery two or three cells that claim a life longer than the six-cell models. Is possible?
Kohut: There is a fine line. capacity has increased in recent years by making cells more energy dense. It There were two hours Ah (Ampere) cells but the cells now go up to 2.9 amps. If you can control the highest concentration energy in the smallest space, it is not a problem. But sometimes it results in violent reactions such as overheating and overcharging. [If a vendor claims its battery lasts a long time with fewer cells,] you want to ask how many watt-hours, the pack holds, and the type of cells (2.6, 2.9 Ah, etc.).
If consumers trust third party batteries?
Kohut: Well our own battery warranty, but if you put a battery of others, you will void the warranty. That's because there's a good Dell XPS M1530 battery manufacturers and there are bad. Some of these good are Panasonic, Sanyo and Sony. A less reputable company will buy the least expensive, and just down there. The reason why many of these incidents occur in the battery industry because of quality control.
We always say you get [life Your laptop] into your own hands when you buy a third battery. Yes, you save money in advance, but you not support the company behind it.
