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.

When I try to turn on my laptop without any battery but plugged in, it boots fine.. but windows does not start.. so is it ok to take out my laptop battery while the laptop is switched on (and windows loaded) so I will only use my laptop on the power supply?

 It should be fine to remove the battery whilst Windows is running, as long as there is a mains power supplyconnected. Whilst it is, I believe the battery is not used, but merely charged. It is only when the mains is disconnected, then the laptop battery is used.

 I was reading online, that it might take up a few charging cycles, although it’s not being used.. IDK, some people said it’s false.. other said it’s true.. my main concern is, as I already said in another thread.that if I leave my laptop overnight with the battery in place and the main supply disconnected it discharges the battery. so I want to unplug the battery.. but I have to plug it back in for windows to load.

 Well, I fixed it. When you remove the laptop battery it resets the BIOS (or something like that).. because I can overclock it from there, so in case I screw up something and it doesn’t boot.. I remove the battery, plug it in and it will reset everything(says it all in the BIOS, I have a dedicated section for overclocking).. So, what I think was happening is.. because there was no battery it resetted the BIOS settings and didn’t save them again (because I didn’t plug in the battery) so I pressed DEL, set the HDD as boot (DVD-RW Drive was 1st) saved, and then it booted up.

A day will come when your laptop battery will no longer charge and instead serve better as a paper weight. As you use your battery more often, the battery loses more and more capacity until it finally won’t accept a charge and goes flat. Replacing a battery is easy, but the new battery price could be so steep that it costs more than the laptop is worth. Buying a refurbished battery can drive the price down even lower, but what if you are super cheap? Well, we are going to cover this last option, which means tearing apart your old battery and fixing it yourself.

 Dell Inspiron 6000 Battery Specs:

  Part No: Inspiron 6000

   Battery Type:    Li-ion

  Volt:  11.1V

  Capacity:   4400mAh

    Brand:    DELL Laptop Battery

Teardown Process

Breaking the battery apart was probably the single most painful moment of this entire article. I had no documentation to work with, the plastic halves of the battery were glued together, and all I had was a mini snipper. I first started by peeling off the top sticker exposing the open framework with cells in view. After this I took my little snippers to the plastic, and cut away piece by incredibly small piece till the entire top was removed. I had black plastic bits flying everywhere; I think even into someone’s can of soda. The end result was a brutalized battery case that looks 100 percent safe for future use.

 Once all of the excess plastic was removed, I could get to the cells I would be replacing. All of these were glued in place, so prying them out with a screwdriver was the only option. As I slowly lifted each group form the plastic case without shorting any circuits, I took my clippers to the metal bridges to fully disconnect the batteries. During this time I also made special note of the wire leads off the charging circuit and where they connected for future use.

Finding the Correct Replacement Cells

Who would have thought finding something as simple as US18650BR batteries would be so hard? It actually took two of us about 30 minutes to find a site that sold equivalent batteries. We narrowed in on www.battery-replacement.org , as we found it mentioned on some odd website as a place to find batteries. Now the standard name for the battery size we were looking for was 1650, and we picked one at random since they had quite a few options to choose ..and I was too lazy to run the math on the correct cell capacity. With the cell selection locked in I ordered the batteries, and sat patiently until they would arrive.

Build Day

Once the new batteries arrived at the office, I got to work on prepping the batteries for installation. I verified battery orientation from the pictures of the old assembly, and started to solder together pairs of cells. I used some old wire to bridge together each group on the positive and negative side, and hooked the first battery group to the red power lead. Next step was soldering together the second group, attaching it back of the first group, and soldering both charging leads in place. Last was the third group soldered to the back of the second, and attaching the black lead to the rear of the battery group. The final result doesn’t instill much confidence of a non-firey demise, but it was finished. To add a layer of safety I placed some packing tape over the exposed battery groups, and mashed the “rebuilt” battery into the bottom of the laptop. To the surprise of all those around me, the battery did not ignite into a ball of flames, and actually started charging.

Performance

The Dell Inspiron 6000  laptop was not the pinnacle of mobile performance from the start, but with the old battery it was difficult to get more than 25 minutes of life before the laptop shutoff. Anything above that value with the rebuilt battery would be a mild success, so I crossed my fingers and hoped that an hour of smoke inhalation (soldering) wasn’t wasted. The results of the rebuilt battery ended up being roughly 47 minutes of battery life, and a Dell battery warning saying the battery had reached the end of its useful life. While the cells were fresh, the batteries charging circuit hard already reached the point of no return. No matter what we could do, it would never reach the charge levels of its prior brand new state.

Conclusion

With the labor involved in rebuilding the battery, and the $53 spent on parts, the DIY rebuilt Dell battery never got anywhere near the performance of a new battery. Although it was a fun process the money could have been better spent on a professionally refurbished battery or a brand new replacement  battery from www.battery-replacement.org . Even if the rebuilt battery did achieve results similar to those of a brand new module, I don’t think anyone in our office would have trusted that laptop to charge unwatched for any significant period of time. With brand new batteries exploding left and right, do you really trust something you rebuilt yourself?

Pros

• Tons of soldering smoke that freaked out coworkers
• People don’t mess with you after they see this in your hand

Cons

• Bringing this through airport security creates a stressful and unhappy situation

I want to use an laptop battery for my new laptop system,but i don’t  confirm that i can really use it in my new laptop.So i call the laptop battery service,he tell me some laptop system knowdage and  how can i do?

Li-Ion cells are permanently damaged when their charge drops below certain levels. If the voltage gets too low, the laptop battery will stop working and become unsafe to use. Therefore all systems powered by Li-Ion laptop batteries have a predefined threshold set to shut down at certain levels of discharge. As a result, Li-Ion laptop batteries are made to the exact specifications of the systems they are designed for, and vice-versa. This is where laptop batteries from another system or low-cost generic laptop batteries may not be compatible. If the thresholds of the system and laptop battery do not match, there is a risk of power cutting off at the wrong moment. This may lead to unsaved work being lost, data corruption, or irreversible laptop battery damage.

In addition, generic low-cost laptop batteries are not made with the high safety standards of official laptop batteries. Main-brand laptop batteries use only approved safety circuits in their laptop battery packs whereas there is no regulation of off-brand laptop battery production. This, as well as attempts by laptop manufacturers to ensure approved laptop batteries are used, is responsible for the higher cost of official laptop batteries. There have been reports of laptops rejecting generic laptop batteries (to avoid usage of potentially dangerous laptop batteries) without software changes (bypassing the security system). Some generic laptop batteries even fail to work altogether.

There are subtle differences in design, manufacture, and the operation of generic and official laptop batteries which may or may not cause problems for you. For every person that has had problems using generic laptop batteries, there is another who has had no problems whatsoever. You must decide if saving a little money on a replacement laptop battery is worth the potential risks.

1. When no external power supply situation, if the working conditions at the time being less than PCMCIA card slot, it is recommended to remove the card first to extend battery life.
2. At room temperature (20-30 degrees) for the battery of the most suitable working temperature, the temperature is too high or too low operating environment will reduce the battery life.
3. Can provide a stable power supply in the environment using a laptop computer, remove the battery for extended battery life is affected by incorrect. On the Asus notebooks, when the battery fully charged, the battery charging circuit will automatically shut down, so the phenomenon of overcharging does not occur.
4. Suggested an average of three months to conduct a battery power correction action.
5. To minimize the number of battery
The number of battery charge and discharge is directly related to life on one charge, the battery on a step forward to retirement. Suggest that you try to use an external power supply,
6. Use an external power supply when the battery removed.
Some users often several times a day Plug Power, and notebook computers equipped with a battery, to do so, even greater damage to the battery. Because each access to external power supply is equivalent to the battery charge time, battery life shortened by a naturally.
7. Power exhaustion after the charge and avoid charging time is too long
Whether your notebook to use nickel-metal hydride or lithium-electric power, it must take charge after the exhaustion of power (capacity less than 1%), which is the best way to avoid the memory effect. Lithium-Ion battery memory effect will be the same, but it is the memory effect than nickel-metal hydride smaller Bale.
8. Usually Caution
When used in peacetime to prevent exposure to prevent damp to prevent the erosion of chemical liquids, avoid contact with the battery contacts with metal objects, etc. happen.
On core laptop batteries:Currently laptop battery can be divided into 4 core, 6-cell, 9-pin, 12 cores. In short, four-cell battery life 2 hours, 6-core, compared with 3 hours, and so on. Of course, the greater the number of cores, the longer the life, of course, the higher the price. Ordinary home users recommend the use of four cores, since it is mainly in the home, have a stable power supply. Recommended 6-pin general office users. If there is a higher demand for mobile office, you can consider 9-pin and 12-cell battery.

Use rechargeable batteries for notebook computers, one of the relative advantages of the desktop, it can greatly facilitate a variety of environments the use of notebook computers. Introduced the first battery is nickel-cadmium batteries (NiCd), but this battery has a “memory effect”, each charge shall be required before discharge, very easy to use, and soon was nickel-metal hydride battery (NiMH) replaced, NiMH not only failed to “memory effect”, but can make more per unit weight of 10% of the electricity. The most commonly used battery is lithium-ion battery (Li-Ion), it is also no “memory effect”, as compared with the NiMH per unit weight gain more power, the price twice as high than the NiMH. In the same weight, this three kinds battery is 1:1.2:1.9 ratio. There is also a battery-called polymer, a very high capacity, small size, most used in Apple Computer.
Laptop batteries currently used in three kinds of main categories: 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Li-ion battery; they are generally expressed as: Ni-Cd NI-CD, Ni-MH NI-MH, Lithium-Ion battery Li-ion.
The purchase or replace the battery when the laptop for many users, the “batteries” may be unfamiliar. The outset, batteries and battery are two concepts. A battery is composed of several slightly larger than the thumb, cylindrical, height of about 7,8 cm, voltage is 3.6v of small units, a professional name for that is called 18650, Sanyo and Samsung is the largest producer. Batteries , like a small battery, through the series combination, that is, we see the battery has. Then talk about how to determine if the battery is several cores:
One way: Disconnect the battery to the number of contacts to see him, there are a few of the tens of cores. But this is a “minister” approach. Let’s take a look at “Cao Chong” is how, “said the elephant”: the look of your battery nominal number of v, such as 14.4v, and then divided by 3.6 to be 4, then proved to be four batteries together in series. And then take a look at the capacity of the battery block, for example 4400mAh, then prove that the above mentioned two sets of batteries in series, because the small battery capacity is 2000-2200mAh, or even more, and together the two groups can be achieved must be 4400mAh. According to these two judgments, then the battery is 4 × 2 = 8 cores.
The composition of laptop battery
Laptop battery from shell, circuit boards and batteries, belonging to lithium-ion battery. People are talking about batteries in general refers to the number of batteries within the battery, mAh refers to the laptop battery capacity.
Mainly by the protection circuit board (or the secondary protection circuit), and the capacity of directed circuits of two parts,laptop battery charge and discharge and safety management.
Laptop battery standby time mainly by the mAh value to decide. Under normal circumstances, a few more batteries, mAh value is greater the longer standby time. Laptop battery life mainly by the charge and discharge times to measure the quality of the products are generally eligible for 500-600 times. Therefore, the effective use of laptop batteries within a period of two years, expired the battery will be aging, standby time affect the sharp decline in the mobility of notebook computers.
Laptop battery tips
In fact, how to make good use of laptop battery, how to extend their use of time and the use of life and so on, is undoubtedly the troubled minds of the majority of notebook users, a problem, the use of laptop batteries There are many methods and techniques, which requires us to usually use more learning and application.
(A) rapid access to hibernation
Temporary non-use of laptop computers, in order to conserve laptop ac adapter, we can set the power management program, allowing the system to enter sleep mode after a period of time, but this is a shorter or longer will have to wait a few minutes, there is no way to make laptop computer system immediately enter the sleep state?
Notebook computer system to enable quick access to dormant state of a simple method is to directly close the display. Press the display would require little effort, you can make notebook computers into sleep mode immediately and effectively conserve battery power. When you need to re-used time, as long as the opening screen, the system will automatically return to pre-operational state.
(B) the screen-saving mode
TFT screen is the largest notebook computer power components, in order to reduce its use of the battery when the power consumption, notebook manufacturers have devised ingenious schemes, but in general are based on the lower screen brightness, and even turn off the screen method.
In some notebook computer’s power management settings you can customize the brightness of the screen, most of notebook computers by a specific shortcut keys adjust screen brightness, generally 6 to 8-level brightness adjustment.
(C) energy-saving settings
Desktop machines using alternating current, most people may not be the computer attached great importance to energy-saving features, but need to use battery-powered laptop computers, the use of energy-saving features should be taken seriously. How to design computer hardware more energy-efficient, this is not a user problem to be solved. The user can do is set up on the computer the effective use of energy-saving option.
Energy-saving settings require the user to adjust two: First, the computer’s BIOS setup program on the energy-saving mode in the settings; most important thing is there are many energy-saving in the operating system settings and operations. In the practical implementation of computer systems, Windows systems should take precedence over energy-saving settings in the CMOS settings.
1. BIOS in the energy-saving settings
In the CMOS settings, most had a “Power Savings”, which can choose to “Maximum Battery Life” and “Maximum Performance” and other options. “Maximum Battery Life” is the default power saving mode setting. Notebook computer power saving mode in several states, such as the Idle Mode Idle Mode, Standby Mode standby (wait) mode, Suspend Mode suspension (sleep) mode. Notebook computers, these settings have been able to regulate power consumption, mainly in the computer into energy-saving state, the timely closure of some without the use of the system equipment. If the wait state, turn off the screen and hard drive; into hibernation, apart from a close monitor and hard drive, but also the contents of memory can be saved to the hard disk, the basic maintenance of the entire computer system shut down, once activated, or restart the computer, desktop will be accurately restored to pre-hibernation state. The energy-saving settings in the CMOS, mainly set by the Idle Mode to enter Standby Mode to Standby Timeout time, set to enter Suspend Mode from Standby Mode to Suspend Timeout time. Phoenix BIOS notebooks are most common. Different energy-saving BIOS settings may be somewhat different, it should carefully read the screen prompts.
2. Windows in the energy-saving settings
For the average user, in the Windows system to operate a better understanding of energy management can be simpler. Windows Help file, in the “management of hardware and software” entries, there are two notebook computers with energy-saving elements relating to: “Managing energy consumption” and “use of portable machine” in the “management laptop on the power.” Energy-saving settings during Windows, should read the contents.
In the Windows “Control Panel”, click “power management”, you can open the “Power Management Properties” dialog box. In the “Power Management Properties” dialog box, should be “power scheme” is set to “Portable / Laptop” and reasonable arrangement “system waiting for”, “close the Monitors”, “Turn off hard disks” and other options for . Different computer can control the option to have some differences, the new factory and the latest computer software will be more workable options, detailed settings should be based on the computer’s own features and Windows Help files to carry out.
In addition, if your laptop built-in infrared port, not the time to ban it, it can be extended laptop battery life.
(D) alarm settings
Set battery alarm in time to give prompt the user to save the information. Way is to click on Open “Control Panel”, double-click “Power” option, point “alarm” menu bar, “low-battery alarm” column, Windows 98 default is 10%, “a serious shortage of the battery alarm” column, Windows 98 default is 3 %, which may make the appropriate modifications as needed. Click both the [alarm response] button, the “voice alert” and “displays the message” are selected, “the power level” may from time to select. Alarm limits so that when the battery is used, it will pop up a warning window, and the alarm buzzer sounds to alert the user to save information on a timely manner. Finally click [OK] button to exit the power management settings.
(E) open the energy-saving function
In the “extended laptop battery life technology” section, we have introduced energy-saving feature is the use of a CPU technology, which allows the performance make notebook PCs to play with their battery life between the time to achieve the best balance.
Most new models of notebook computers both in the BIOS of the CPU energy-saving technology have given the support, by default is turned on, if not open as long as the enter the BIOS will support the option to open it OK.
(Vi) The use of third-party software to monitor battery status
In addition to Windows built-in power management features, there are many utilities available to monitor the battery condition. For example, PowerCenter is a power monitoring tool available for free download (http://me MBers.xoom.com / TimothyBug / powercenter / index.htm). Only 800KB, is designed for notebook computer services software. In addition to the amount of PowerCenter shows the percentage of battery, but also to show the actual time and hours of time can be used.
PowerCenter total of three kinds of display.
(1) FullDisplay: In the open window displays detailed information, including the use of battery or AC power, the battery percentage and the remaining time available.
(2) CompactDisplay: in use is always at the top of the window display.
(3) MinimizeDisplay: make PowerCenter reduced to the Windows task bar, display the information is relatively simple.
PowerCenter is also attached to a control center, can be made up to six kinds of warning. When the battery – down to a certain level, a timely warning to the user, save the file being processed. In order not to waste electricity and CPU resources, PowerCenter automatically detect the battery status changes.
(G) intentionally run out of battery
Run out of battery on a regular basis in order to ensure a full charge. If you need to completely run out of battery power in the specific practice is: In the Power Management dialog box, select Battery Drain this particular power mode, all of its 3 Running on Batteries options are set to Never, this notebook computer on the will continue to run. Select the mode, and then enter the Alarms tab to lift the Low Battery and Critical Battery Warning check box is a check mark (so, when the battery power is low, the machine will not enter the suspended state). Next, let the computer run the CPU-time tasks, such as the computer automatically run a number of computational complexity of the 3D demo program, so soon run out of battery power remaining, of course, these disposal not forget to unplug the AC plug.
(H) to activate the first time, laptop batteries
Most notebook computer manufacturers of the products leaving the factory when they said that the new laptop to buy should be in full discharge of the case, repeated three times the battery fully charge / discharge, charge, preferably more than 14 hours. That is such a word, so that the notebook PC users in the wrong point of view.
In fact, before the laptop will be right products at the factory inside the cell to activate, in order to avoid the natural wear and tear affect battery performance, only with a small amount of electrical energy. Since the completion of a laptop battery is fully charged it will automatically stop working, there is no need to maintain the charge time to 12 hours. In general, buy a new laptop just in the normal charge / discharge activation can be conducted.
