IBM laptop battery We recently purchased an Acer EMachine laptop for my son for Christmas. laptop battery We purchased the machine on Black Friday at Walmart for $199. Well Christmas came and my son opened his gift from Santa and found that the screen was cracked. The seal on the box was not opened until Christmas. He was devastated but we called Acer to see what we needed to do to get this repaired under warranty. To my surprise, Acer’s customer service informed us since it appears to be a consumer damage that it voids the warranty and if we wanted it fixed, Dell 8N544 Battery, we need to pay $199 to get it repaired. I spoke to 2 service representatives (who did not speak English that well so I am assuming it is not a US call center they are using) who stated the same response – consumer damage warranty not valid. I requested to speak to a supervisor and was given the floor supervisor. He also stated that since it was consumer damage, I would need to pay for it. I was informed by one of the customer service reps that I would need to speak to the 2nd level department regarding the repair on Monday since they were not in on the 26th. We called Monday to be told there is not a 2nd level department and again that since it was consumer damage, we would need to pay for repair. We were quite surprised to learn that this company is not consumer friendly. We did however go to Walmart to explain all this and the Walmart Supervisor worked wonders. They are returning the product to Acer to get it repaired. Walmart is paying to have it shipped back to Acer in Texas but when we had to give Acer our address, the customer service representative again had to add that it was consumer damage although the Walmart Supervisor and the Acer customer service representative already agreed that it was not in fact consumer damage. FRU 92P1141 Do not buy Acer products – They do not stand by their product nor do they do a thing to make the consumer happy. Dell Latitude D800 Battery, Dell Inspiron 8500 Battery, Dell 8N544 Battery, Dell Inspiron 8600 Battery, Dell Inspiron 6400 Battery, Dell Inspiron E1505 Battery, I will continue to inform family/friends all do not do it – You pay for what you get – Pay a low price for a laptop and look what happens – you get crappy customer service and crappy service from a company.
I have an Acer Aspire 5315 that I purchased a couple of years ago at Walmart for approx $350. It is/was no big deal to make the recovery disk.
The PC recently survived having a half cup of coffee knocked onto the keyboard by my cat. (Had to clean under the keys and let the PC dry out for three days.) I was totally shocked when it turned on!
A month after the cat/coffee incident, the battery died. The only symptom was that it would not turn on. Prior to my investigating the problem (via on-line blogs) and realizing that all I need was a battery, I looked into getting another Acer. I think it is a great little sturdy machine that does not come loaded with a lot of junk software. I imagine that’s what keeps the price low – $330 – significantly lower than similar machines from competitors.
Perhaps the users that had such issues cannot handle the flexibility provided by FRU 92P1139 Acer with their laptops. My only regret was the short battery life.Dell Inspiron 6400 Battery I will be thrilled if the eight hour battery really lasts that long without adding a lot of weight to the machine and I will definitely look into an Acer for my next machine
I bought an Acer from Walmart for $498 a couple of weeks ago, mainly because of the long battery life they claim. Like many other laptops it came with no rescue disk or other disk of any kind, but asked me to make my own rescue disk using 2 DVD disks. That’s as far as I got because it bombed out while trying to create the rescue disks and never finished. Imagining the jam I would be in if the PC would go belly up without any disks to reinstall the operating system with, I promptly returned it to Walmart within 2 hours after buying it. It’s a shame these companies have gotten so cheap that they do not even provide a rescue CD or install CD with their computers.
I got my Acer Laptop from my Husband for Christmas. It has been a nightmare. I’m so mad because I put all my Business information on it and it went out on me. My Daughters also went out on her too. She lost all her Pictures and Music. I wish I had never even got the ACER. It has coast me nothing but Money and Problems.
Q: When I lost power last weekend, my six-year-old laptop shut down abruptly, even though its battery supposedly had a full charge good for three hours. Does the battery have a problem?
A: Yes. The lithium-ion batteries in most laptops lose a little capacity after each charge/discharge cycle.
How much? Hewlett-Packard estimates that its models will drop to 80 percent of their original capacity “after 300 cycles or about one year of use.” 40Y6799 Dell advises that most people will see “noticeable” declines in battery life after 18 to 24 months.Dell Latitude D800 Battery, Dell Inspiron 8500 Battery, Dell 8N544 Battery, Dell Inspiron 8600 Battery, Dell Inspiron 6400 Battery, Dell Inspiron E1505 Battery, And Apple says its batteries will fall to 80 percent capacity after 300 cycles, while the inaccessible units in its newest laptops will take 1,000 cycles to reach that point.
I’ve seen major reductions in run time with batteries just a couple of years old. After six years?Dell Inspiron E1505 Battery Forget it — the battery’s gone. Get a new one, and consider buying from an aftermarket vendor that may charge less than the original manufacturer.
Q: The plastic case of my USB flash drive cracked. How long can I expect it to work?
A: It may function indefinitely. A few years ago, a cheaply built flash drive’s case fell apart at my desk, exposing the circuit board. The drive still lights up and works when I plug it into a computer.With its Aspire Timeline, Acer is claiming 8 hours of battery life. That’s the same time Apple claims for its MacBook Pro 17-inch laptop, a figure we recently put to the test.
Behind the Aspire’s longer life, says Acer,Dell Latitude D800 Battery, is the combination of Intel Core 2 Duo ultra-low voltage processors and Intel Display Power Savings Technology (Intel DPST), which Intel says “reduces the display backlight with minimum visual impact.”
Acer had the longest battery life in our recent netbook Ratings,40Y6797 (available to subscribers) with its 10-inch Aspire One lasting 9 hours in our tests.Dell Latitude D800 Battery, Dell Inspiron 8500 Battery, Dell 8N544 Battery, Dell Inspiron 8600 Battery, Dell Inspiron 6400 Battery, Dell Inspiron E1505 Battery, We’ll see if its new 11.6-inch Aspire One netbook, also launched this week, lives up to its predecessor’s battery life as soon as we get our hands on one.
Where there’s power, of course, there can also be heat, especially now that batteries are cramming more power into less space. The Timeline laptops will use another Intel technology to reduce heat by redirecting airflow to the bottom side of the chassis and the wrist rest areas.
While we of course can’t yet say how well that cooling technology might work, when it comes to heat, Acer laptops have run cooler than the competition in our tests in recent years. (Our laptop testing actually includes a “lap test” that measures the temperature of the bottom of the laptop after it’s been stressed; see minute 3:10 our Laptop Buying Guide video. The hottest laptops, ThinkPad T60 thermally speaking, have been models from HP and Apple.)

Answer: encounter this problem, you can refer to article stated the correction of your laptop battery to achieve optimal performance. If you still cannot solve, please contact with your supplier for replacement.
2 q: new battery can drive the computer how long?
Answer: the notebook batteries running time is difficult to determine. The actual operation of electric equipment on time depends on the size of the screen, and other accessories, hard disk, the extra power consumption are greatly shorten the running time of the total operation time, battery also depends on equipment design.
3 q: battery completely finished just charge would reduce life?
Answer: the battery life commonly, fully charged according to the number of lithium battery is commonly 300-400 times. Of course you don’t have to worry about switch on the power of a battery, the battery charging the battery number only when complete full charge will increase.
4 q: battery charging to a certain percentage even after the break, 100% of the AC power, not discharge battery, computer shutdown, immediately? Why?
Answer: (1) to see your work environment temperature is too high in the air temperature is higher, if the area, long battery will happen is used to prevent accidental, protect the computer program will start working, now you terminate computer can be off your computer, you can put battery, to put it back.
(2) computer recharging circuit in charge of time is the most easily of germinal problem, another is probably your computer in the process of charging, problems. Please check your computer. You can find the original battery, whether can work at the computer.
5 q: I cannot identify the dell laptop battery, and display the battery can compatible with this computer, insert dell battery “information, and lights flickered continuously, and this is what is the row?
Answer: this information indicates that the battery, when the compatibility of the fault, please contact with your supplier for replacement.
6 q: when I put a battery into the computer, computer automatic shutdown, but will battery, the computer can work normally, is this why?
Answer: the battery has fault. This kind of situation is very few, the reasons may be short-circuited batteries interface part caused by the technology failure. Encounter this failure, please contact with your supplier for replacement battery.
7. Ask: new battery charging is why not?
Answer: all the laptop battery manufacturer in shipping, notebook batteries will be charged battery of 40-50. Generally we suggest a night charge (about 12 hours). A new laptop battery charging circuit should use early charging depth and depth (discharge) 3 to 5 times, make the battery performance to achieve optimal. (note: in the process of charging and discharging battery has a certain temperature is very normal). The new battery charging is difficult to use adapter, because they never charging depth. If this happens, remove battery, then re-insert. Should start charging cycles. The first battery that may happen. Don’t worry, it is perfectly normal.
8. Ask: my original battery of nominal voltage is 14.4 V, constant or 10.8 V PuTai surplus that sales of corresponding type of battery nominal voltage and I not only the nominal voltage, recent V V, but also 11.1 or can be used in the same indicate is how shall I choose?
Answer: the laptop computers, which work safety voltage dc, is in 5.5 V – 24V between. We are equipped with the battery, is a rated the required safety voltage range. As everyone knows, we have used batteries are lithium ion battery, and lithium ion battery of its own characteristics are: charge the battery voltage will heighten, Put through power voltage will be reduced. For example a nominal 11.1 V battery, which can provide practical and effective working voltage range is mbm1260 V 9V battery, when – the voltage in full, and when mbm1260 V battery electric voltage after put about 9-10V, namely between the 9V – is mbm1260 V shop to eat can provide the effective working voltage computer work. The dc power supply from computer design principle, all the notebook computer manufacturers are such computer mainboard design of power lines, so whether you use original battery nominal voltage is 10.8 V, 11.1 V, or 14.4 V, recent V, all can be used alternately, and the other is safe, please feel free to use.
9 q: how to achieve optimal calibration laptop battery performance?
Answer: the laptop battery within a microprocessor software, it can be in charge of the electricity. The battery must be calibrated periodically to ensure screen display, and the correctness of the percentage. You should use your computer in the first operation, when implementing the after every few months.
(1) first of “power” option set: right-click on screen space, select “properties” – “the screen saver” – “power” – “power use” – “portable/pocket type”, and “when computer” battery “all options” never “, “warning” cancel “under the battery shortage alarm” and “battery” serious shortage of alarm function.
(2) broken power adapter and use your computer power battery until completely.
Connect the ac adapter (4) until the batteries that 100%. In the first time use (or through a long-term storage battery needs 3-4 times full circulation to achieve its full put the best performance, the process requires at least 14 hours.
Tips:
(1) you must first discharge of your battery charging full power to computer again to 100% of the calibration, after the battery power is, no matter what you may at any time, or broken power. In addition, in a period of time can make a protection circuit under the control of deep filling with the battery power put correction, but it won’t improve your battery capacity of actual.
(2) when the battery is changed “empty” forced into hibernation, computers, cell model of a certain power fact reserves to ensure that the computer can dormant for a period of time. When the battery is fully exhausted, the computer will be mandatory shutdown. At this moment, any open documents will be lost.
10. Ask: why for the first time in 10 minutes, the battery charging and computer?
Answer: encounter this problem, you can refer to article 11 of correction of your laptop battery to achieve optimal performance. If you still cannot solve, please contact with your supplier for replacement.
11. Ask: my battery first can use 3 hours, but the second is unable to recharge the batteries, isn’t that bad?
Answer: encounter this problem, you can refer to article 11 of correction of your laptop battery to achieve optimal performance. If you still cannot solve, please contact with your supplier for replacement.
12 ask: my batteries in advance warning is not enough in a suspended state before, batteries always leads to computer automatic shutdown, several times, but now in a few minutes after the full use of, is this why?
Answer: encounter this problem, you can refer to article 11 of correction of your laptop battery to achieve optimal performance. If you still cannot solve, please contact with your supplier for replacement.
13. Ask: why not use battery power is also reduced.
Answer: because environmental humidity and the absolute insulation environment influence, battery power phenomenon exists since, depending on the degree of the battery and quality, 3-4 days will decline, so just isn’t around 2% of all attribute normal phenomenon.
14 ask: use the battery power to take?
Answer: we suggest not remove battery, in order to prevent the ac power in a sudden interruption under the condition of the ongoing operations can continue without loss of data. If the battery is suggested to take place in plastic package in dry and cool, and remember, 1 months at least once use rechargeable batteries and to avoid the battery loses activity.
15. Ask: my batteries in charge, after 20 hours to 0%, electricity, still AC power and broken, computer immediately after shutdown, why?
Answer: the first to check whether the notebook batteries and good contacts, because if contact is bad, though the battery can be read data communication, but he cannot give the battery. Now you can try the battery several times. Insert the battery computer as a voice heard du, can have good contacts. Try a few times, can eliminate the computer and battery contact problem. Especially in the use of computers, IBM should pay attention to this problem.
Q: how to 16) battery charging and discharging notebook batteries?
A: please follow the steps below to battery charging and discharging,
(1) the new battery pack into a laptop computer
(2) disconnect notebook adapter, using a laptop computer until it automatic shutdown. This is a depth discharge process
(3) adapters, battery charging began
(4) until the batteries charging
(5) repeat charging and discharging cycle times, you will reach the top of the battery
But ask: when the battery is fully charged battery can display, 7 minutes, but in fact battery can 2.5 hours, then the battery internal electronic devices (show) is that part of the state problem?
Answer: there is a new battery charging first approved by the ego. After period of time, will be displayed properly. Please set the computer shutdown of the required minimum power electric management system. Disconnect the battery power adapter using computer knows all used up. Then connect the adapter start charging. Depth of battery charging and discharging or cycle of 3-4 times to ensure the battery performance to achieve the best.
Ask: how to calculate the battery can be bought my new computer use several hours?
Answer: general a battery of time, and computers are directly related to the power consumption.
As one of the computer screen, 10.4 inch with low electrical work, then the computer CPU per hour of power consumed by normal use in 10WH – 12WH between, battery work can provide the power output calculation method for: nominal voltage is multiplied by the nominal capacity, the battery can provide the total power output.
For example a nominal 11.1 V, 4400mAh notebook batteries, can provide the power output, so the WH 48.8 battery in the 10.4 inches on a computer can provide the normal working hours for about four hours. The computer USES the power consumed by the use of the computer, and it also has a direct relationship status, if is playing the game or watching DVDS and computer in full operation state of power also will increase, so the battery time also is met subsequently shortened.
Then ask: how should a storage battery?
Answer: (1) if you want to keep laptop battery performance stable, it must often work independently batteries. If the battery in the form of the closed for a very long time, the battery will be damaged.
(2) a month or more time don’t use the battery, the battery from within, the computer to 60-80% of charging and stored in a dry, cool and clean place. If long time without words, battery power will eventually loss and damage. Therefore it is necessary in store for a period of time after the battery recharging. Of course, if you can use a word each month, will be able to better ensure the storage battery.
20. Ask: make battery safe should do?
(1) avoid will cause short-circuit, batteries battery into short-circuit will cause serious damage to cells,
(2) to avoid falling, beating battery, which will may lead to corrosive substance exposed core inside,
(3) will be exposed to avoid heat and moisture battery and rain,
(4) battery should stay away from the fire or other extreme heat, battery exposed to extreme heat next may cause an explosion,
(5) avoid sun exposure in battery,
(6) shall not open, repair or tamper with the batteries. Batteries overheating will burn. Mordants alkaline solution or other solid electrolyte leakage causes fire or damage.
(7) don’t use sharp objects piercing batteries.

14 ask: use the battery power to take?Answer: we suggest not remove battery, in order to prevent the ac power in a sudden interruption under the condition of the ongoing operations can continue without loss of data. If the battery is suggested to take place in plastic package in dry and cool, and remember, 1 months at least once use rechargeable batteries and to avoid the battery loses activity.
15. Ask: my batteries in charge, after 20 hours to 0%, electricity, still AC power and broken, computer immediately after shutdown, why?Answer: the first to check whether the notebook batteries and good contacts, because if contact is bad, though the battery can be read data communication, but he cannot give the battery. Now you can try the battery several times. Insert the battery computer as a voice heard du, can have good contacts. Try a few times, can eliminate the computer and battery contact problem. Especially in the use of computers, IBM should pay attention to this problem.
Q: how to 16) battery charging and discharging notebook batteries?A: please follow the steps below to battery charging and discharging,(1) the new battery pack into a laptop computer(2) disconnect notebook adapter, using a laptop computer until it automatic shutdown. This is a depth discharge process(3) adapters, battery charging began(4) until the batteries charging(5) repeat charging and discharging cycle times, you will reach the top of the battery
But ask: when the battery is fully charged battery can display, 7 minutes, but in fact battery can 2.5 hours, then the battery internal electronic devices (show) is that part of the state problem?Answer: there is a new battery charging first approved by the ego. After period of time, will be displayed properly. Please set the computer shutdown of the required minimum power electric management system. Disconnect the battery power adapter using computer knows all used up. Then connect the adapter start charging. Depth of battery charging and discharging or cycle of 3-4 times to ensure the battery performance to achieve the best.
Ask: how to calculate the battery can be bought my new computer use several hours?Answer: general a battery of time, and computers are directly related to the power consumption.As one of the computer screen, 10.4 inch with low electrical work, then the computer CPU per hour of power consumed by normal use in 10WH – 12WH between, battery work can provide the power output calculation method for: nominal voltage is multiplied by the nominal capacity, the battery can provide the total power output.For example a nominal 11.1 V, 4400mAh notebook batteries, can provide the power output, so the WH 48.8 battery in the 10.4 inches on a computer can provide the normal working hours for about four hours. The computer USES the power consumed by the use of the computer, and it also has a direct relationship status, if is playing the game or watching DVDS and computer in full operation state of power also will increase, so the battery time also is met subsequently shortened.
Then ask: how should a storage battery?Answer: (1) if you want to keep laptop battery performance stable, it must often work independently batteries. If the battery in the form of the closed for a very long time, the battery will be damaged.(2) a month or more time don’t use the battery, the battery from within, the computer to 60-80% of charging and stored in a dry, cool and clean place. If long time without words, battery power will eventually loss and damage. Therefore it is necessary in store for a period of time after the battery recharging. Of course, if you can use a word each month, will be able to better ensure the storage battery.
20. Ask: make battery safe should do?(1) avoid will cause short-circuit, batteries battery into short-circuit will cause serious damage to cells,(2) to avoid falling, beating battery, which will may lead to corrosive substance exposed core inside,(3) will be exposed to avoid heat and moisture battery and rain,(4) battery should stay away from the fire or other extreme heat, battery exposed to extreme heat next may cause an explosion,(5) avoid sun exposure in battery,(6) shall not open, repair or tamper with the batteries. Batteries overheating will burn. Mordants alkaline solution or other solid electrolyte leakage causes fire or damage.(7) don’t use sharp objects piercing batteries.

Maintain stable notebook batteries

Feb 20, 2010 Author admin
Since the birth of notebook computer batteries, on the day of the debate will never stop, because of using notebook computer is one of important technical indicators, and the capacity of the battery determines the notebook computer is an important index. Exactly how to use to maximise the efficacy of battery, extend battery life? Below, we will be listed for everyone to meet some people often without instructions are in error: now the most common lithium ion battery)
A first used batteries, three times before, it needs recharging 12 hours?
It is entirely unnecessary. For now the notebook computer has the power circuit and perfect management system, when the battery charging saturation, control circuit breaker automatically switch to the full, so long as the filling, does not mean that you can use the longer the longer.
Second, in order to prevent memory effects, to finish in charge?
Each time to recharge batteries before discharge is not necessary, and is harmful. Because of the depth of the battery proved: the senseless discharge will shorten the life of the battery, the battery advice when you can use 10% batteries. Of course when the battery has continued to 30% of the electricity charge, while still had better not because memory effect exists.
Third, plug in the ac, the battery down to prevent repeatedly charge?
My advice to you is: no! Of course, you can take the natural discharging lithium ion battery to me, said after the battery, if have natural discharge access will appear repeatedly charge power, reduce battery life. And I gave you the answer, “no”, the reason is the following:
1 now the power control circuits are notebook designed the characteristic: when the battery is about 90% (such as HP’s most models) or 95, and will charge through natural discharge to the capacity of the time for 2 weeks to a month, when the battery leave unused one month to complete the capacity of the battery charge to maintain this time, you should concern is the battery should exercise body rather than the recharging after being sidelined.
2 if battery “unfortunate” was recharging, damage will not cause than long battery power decline of how much bigger.
3 your data than your battery and even your laptop is much more precious, suddenly loses power not only on your notebook is an irreversible damage, it is the time of data.
Four, long-term storage battery requires full of electricity?
See the table below the percentage was clear: the saturated state at the initial value of relative percentage),
Storage battery charging 100% temperature 40%
0 degrees after the year (94%) 98 (after a year),
25 degrees 96% (after a year after year (80%)),
40 degrees 85% (after a year after year (65%)),
After 60 ° 75% (year), 60% (3 months),
Obviously, if you want to put long-term preservation battery, the environment temperature drying and let the battery remaining power in around 40 per cent is most ideal. Of course, every month to take out the battery is best with a battery, which can ensure the preservation condition, good let electricity and total loss and damage to the battery.
Five, when used as possible extension of the time?
1 screen brightness. But large LCD power, can effectively reduce brightness prolong the using time.
2 SpeedStep open PowerPlay and save the electricity, etc. Now the notebook processor and display chip are working frequency and voltage to prolong the using time of the function, open the corresponding options can extend battery time.
3 the use of hard disk drives and velocity DriveSpeed NERO: if the software, PowerBooster software can reduce the disk drive, etc, also drive speed can effectively reduce the notebook.

Correct for laptop battery charging and discharging

Nov 3, 2009 Author admin

In July, Microsoft Windows introduced a new power options, through to the CPU and other equipment to adjust to reduce energy consumption and increase battery life. But in addition to the use of notebook batteries, what exquisite?

Q: laptop battery power to run again until all charge?
A: in this era of lithium batteries, this idea is A misunderstanding. This principle applies only to the cadium battery before. For lithium batteries, use for a long time with test again no any role, even or harmful. Because the lithium battery doesn’t exist the so-called “cache effect”. Laptop battery life only commonly with artificial damage or natural life. Basically, the battery life is fixed, 3-6 times, the charge for the average person, can use 2-4 years.

Q: when the power is connected to pulling a battery?
A: many laptop users have asked this question, then the answer is no, it needs to depend on practical usage. In the dc power supply connection without pulling on batteries battery and no damage, because the battery again after full electric power will not accept any power will inject, all the power supply directly to notebook. But when laptops overheating when running at high speed, internal or remove battery, otherwise the best is harmful.

Q: so how should correctly for laptop batteries?
A: should avoid until 0%, recharging the battery run out, because this will give great pressure and battery damage. A feasible way is in the remaining 10-25% of the power is about to charge.

From the experience of using mobile phone battery, many people may feel laptop battery recharging shall also be all light. But in fact notebook of lithium battery charge “, “light/number is limited, and all the light recharging will only greatly shorten the battery life.

At the same time, the battery should be in charge of the dry places, but also pay attention to the heat problem, this is the enemy of batteries.laptop battery

Buy laptop battery should know that

Oct 30, 2009 Author admin

The notebook computer batteries is relative to the heart, and the advantage of the desktop. Most laptop batteries and now works mostly in the time between 2 ~ 4 hours, may not meet the needs of users. Thus, for those who need to move office or often ambulating, prepare a backup battery is very necessary. Moreover, notebook batteries are used in a year later, consumables its performance will be decreased obviously, plus some customers usually don’t pay attention to and maintenance of the battery, the battery performance quickly and is not a rare example of early scrapping. How to choose a cost-effective battery is keen to know many users. We will talk about the battery.
Notebook batteries and not common battery, the user must first understand oneself before the battery types. Support machine, Most laptop computers using lithium battery, which is the lithium ion battery is common. Another is the lithium battery, but only in some high-end thin laptop. Lithium battery is commonly by core group, the protection circuit and the capacity of monitoring and communication circuit, etc. From the parameters, battery capacity is one of the most concern. Currently battery capacity in 3000 commonly 4500mAh ~ between, also have the capacity of 6000mAh equipped.

The higher the theory, at the same time the configuration used is longer. The manufacturer for laptop battery has a detailed introduction, we often can see the “six core 4400mAh”, “four core values 2200mAh”, but actually nominal battery capacity 4400mAh 2200mAh or not directly determine the working time of the notebook. When we talk about the computer power consumption, total want to use power nominal, rather than simply current. In common 2200mAh, 3.6 V core, for example, some little May 4th series components, the battery voltage, capacity 2200mAh 14.4 V. While many 14 inches above the notebook, may adopt 2 and 4 series of eight core mixed mode, voltage, capacity of 14.4 V 4400mAh achieve doubled, longer time. However, also is the core 2200mAh, 3.6 V, if the 2 and 3 of the mixed mode 6 core, its battery capacity remains for 4400mAh, voltage drops to 10.8 V, if at the time of its use capacity, and eight core battery should be. If the power to calculate, eight core lithium battery, power should be 63.36 Wh, 6 core for 47.52 Wh, four core for 31.68 Wh. If this value, the core of lithium battery 8 advantage to manifest.
When the choose and buy must pay attention to the battery appearance, generally brand battery shell mould is more normative, then when the notebook computer may be difficult or loose from the loading condition; Don’t buy when the choose and buy another coarser and label handwriting clear cell. In addition, some new batteries battery as high guard and revision of the battery, the battery should also pay attention to the electrode wear generally heavier and glossiness traces are not new battery.notebook-battery
