• Introduction

    When I purchased my Apple PowerBook G4 12" about 30 months ago, I was surprised when the battery run time dropped by over 50% in just 15 months. The machine was under Apple Care so I called to inquire. Although 15 months sounded short, battery life is not covered. After paying $120 for a replacement battery, I've been on a quest to understand laptop battery life and how it might be extended.

    The AppleCare specialist suggested not leaving the machine plugged in all the time. I also thought to myself perhaps the original compaq evo n600 battery was weaker than normal. When my brand new Apple replacement battery also lost 50% of its capacity in just 14 months, I realized something else was going on. The purpose of this page is to describe what I've learned about laptop batteries and battery life in the hope of creating a useful reference for myself and others. I welcome your comments to help keep this information up to date.

    Killer Usage Pattern

    My laptop is plugged in and turned on almost all of the time except for an hour or two most days when I run it off the compaq evo n600c battery. I let the machine sleep instead of shutting down so it's nearly always ready to go. The PBG4 is my primary development machine and normally attached to a 20" Cinima Display. It runs warm to hot much of the time.

    Tips For Extending Li-Ion Battery Life

    I've received many tips, some contradictory. Here they are:

    1. Do what you can to keep your compaq evo n610c battery cool. Excessive heat is bad for your battery. This is challenging in the 12" laptop form factor, but a cooling pad might be in order. Consider taking breaks, or otherwise reducing the load on your system.
    2. Re-calibrate your compaq evo n610v battery every month or so by fully charging, fully discharging, and then fully charging again.
    3. Recharge your battery before it reaches empty. I've been told deep discharging cycles are hard on Li-Ion batteries unlike some others which can develop a "memory effect" when not regularly discharged. Based on the re-calibrate your battery every month suggestion above, it would appear that "some" but not too much strenuous exercise is good for your compaq evo n620c battery .
    4. Don't keep your laptop plugged-in all the time. As the charge begins to fade, it will constantly begin recharging.
    5. Charge your new pa3285u-1brs for 12 hours or more the first time it is plugged in and then allow it to discharge fully to maximize its capacity.

    TruePower Experience

    After my Apple replacement pa3285u-2brs experience, I was ready to try an alternative. I ordered a "TruePower" replacement battery based on favorable reviews, longer warranty, and plausible technology description on the FastMac website. Here are some observations.

    1. The fit and finish matched my PBG4 well enough,pa3284u-1brs, but the outside of the case is actually a flexible molded plastic rather than aluminum as in Apple's replacement batterries.
    2. The 12" battery was advertised as 4400 mAh, but CoconutBattery.app (a nice tool for monitoring your battery) shows the Battery Capacity as 4200 mAh out-of-the-box (Battery-Loadcycles: 0). [20-Jul-2006]
    3. After the initial calibration, CoconutBattery shows the Maximum (and Current) Battery Charge as 4492 mAh (more than the original capacity). toshiba tecra a1 battery,toshiba tecra a8 battery,toshiba satellite a15 battery,toshiba satellite a10 battery.

     

  • Kawasaki Heavy Industries, a train specialist that supplies transport firms across the world from London to Tokyo, has come up with a new kind of tram battery that could completely do away with overhead power lines.

    The latest version of Kawasaki's existing Swimo streetcar includes an advanced nickel-hydrogen compaq evo n600 battery that recharges in less than ten seconds - that's sixty times quicker than existing options for trams.

    Dock and go

    As a result,compaq evo n600c battery, the company says tram operators could remove overhead power cables and instead charge their trolleys through platform power docks at each station where they stop.

    Thus, with much of the automotive industry expected to move to lithium-ion compaq evo n610c battery, the older nickel-hydrogen technology may yet have a role in clean transportation.

    Kawasaki says it plans to run a trial in Japan before aiming for a commercial debut of the new super compaq evo n610v battery,compaq evo n620c battery in around five years.

  • Your camcorders battery life is very important. Without battery power you can quickly become useless. Here are some tips for making your camcorders batteries last as long as possible.

    Buy the Longlife Battery

    Buying an additional long life battery is the easiest way to ensure that you have enough battery power to get you through your event. When you buy a long life battery keep your original battery charged as a spare for emergency situations.

    Charge The Battery

    Camcorder batteries can lose charge when they have been stored for a long period of time. Even if you stored the battery at full charge plug your camcorder in the night before to make sure you get the most you can out of the battery when it matters.

    Use the Viewfinder

    Using the LCD screen can be tempting to do when you are recording an event. The LCD screen uses more than twice the battery power than your camcorders viewfinder does however. If you are in a situation where you want to conserve your hp laptop battery power then try to close the LCD screen and use the viewfinder instead.

    Make Your Movement Uniform

    Turning your camcorder on and off and zooming in and out can take up a lot of battery power. You are going to want to zoom, and turning your camcorder off when you are going to stop recording for a while is a good idea. Try to keep things like that to a minimum when you can.

    Buy an External Battery Charger

    If your camcorder uses itself as a battery charger then you may want to consider purchasing an additional external battery charger. If you have two batteries then you can leave one on the charger in the hotel room while you and your family are out for the day, stop back by in the afternoon and switch the battery on the charger for the battery on your camera. With an external battery charger you are able to have a battery constantly charging and also always have use of your camcorder.

According to the technical staff at the scene show that is now in the field of battery technology, various new technologies have emerged, showing a picture of the flourishing of the battery industry has played a significant role. Representative of the technology are as follows.

    - Curing and into the new technology. Curing is an important VRLA battery production process, the initial capacity of the armada m700 battery , have a greater impact on life expectancy. Traditional curing process of the formation of 3BS, if used under high temperature 800C and could be plaster technology 4BS, 4BS manufacturers not only high capacity battery and long life. Used in chemical process monitoring software, can improve the efficiency of chemical production processes and product quality. Hongdan be used to shorten the curing time with the formation, so that curing is easy to control and improve the initial capacity and production efficiency.

    - Grid alloy technology updates. Relevant technical staff, told reporters that the traditional not only corrosion-resistant grid structure is complicated, but also easily lead to premature capacity loss, positive expansion, elongation and a shorter life-span issues such as lead paste with the combination of corrosion resistance difficult grid. In the grid alloy to add an appropriate amount of trace elements can enhance the grid performance. The long run, the grid material and technology should have three characteristics,evo n400c battery , namely, the cooling alloy, making the uniform mixture of all the elements greatly improved corrosion resistance; light grid, aluminum, copper network so the substrate, the surface coating of lead, or the use of glass fiber yarn, the surface of hot-extrusion-coated pewter became the lead wire, and then woven into cloth as a grid of lead; network grid (can be thinned grid), as a result of the use of cold extrusion molding, the proportion of power metal to be cast as well as much improved corrosion resistance, an increase of life expectancy, increased production efficiency.

    - Catalytic suppository technology. Emerson's booth in the former, this reporter encountered a power industry expert, he told reporters, the lead-acid evo n410c battery in most of the telecommunications industry for use in floating state, a high positive potential, oxygen precipitates serious , and the catalytic suppository placed inside the top of sealed batteries, add the traditional mechanism of oxygen and then compound the negative effect of the oxygen cathode was directly precipitated compound, this part of oxygen is no need to compound the negative electrode, thereby reducing the burden of negative depolarization, At the same time to reduce the negative emissions, reduce water loss.

    Experts said that with the battery production process, raw materials continue to improve and update, as the lead resource-rich, gradually mature technology, wide application and has a good reversibility, in a fairly long period of time can be widely used in various fields in. However, high-energy batteries, fuel cells (green energy) and automation, intelligent technology and product technical standards will also be stepped up in our research efforts.

    untitled

    Looked at popular science books when I was a little child,I learned through training in mice with the roller cage in one direction on North Korea to carry out running for the next generation to provide electricity, very strange. But the idea of the industry and the latest ideas, it is necessary to the far less. In order to get laptop power supply to support a longer period of time, the industry invented a patented technology: the keyboard charger.

    Keyboard charger

    The charger is a key concept: a magnet assembly in a number of keys on the keyboard, power button mounted on a coil seat, tapping the keyboard when the user when the magnet coils in the campaign, resulting in induced current, the current through into later To come to the battery charge. It is said that those gathered by tapping the energy of the keyboard, battery life can be increased by 20%. To be playing a joke, the proposal in its notebook computer casings on the coat light bulbs, power failure or Zouye Lu day when beating the keyboard to lighting, is really called "flashlight."

    Energy-saving notebook is a request

    Not long ago, playing one of the old 386 laptop, which does not drive, multi-media did not, of course, can not keep up with current notebook fun, but one thing I feel deeply that the acer laptop battery seems to be very durable. Although there is no computer is now 386 strong computer 3D and multimedia features, but from the word-processing needs of the energy point of view, it is much more energy. In all fairness, the notebook is really not as easy to use desktop, the reason why we use the notebook computers, because we lack a fixed quietly sitting in one place of business conditions, so we have to move office, so we are not the notebook computers for the completion of the What 3D design and video production, not what is used to playing three-dimensional simulation of the game, all the basic word processing, data and Internet use, such as office and therefore may not need the latest CPU and strong 3D accelerator card, it is necessary to know that these two components in the Desktop are in need of cooling fans, that is to say they are energy-hungry. If you care about battery time-keeping, you buy the laptops when they should take these factors into account.

    Nickel-metal hydride acer btp-43d1 and lithium batteries

    At present, the major notebook computer batteries using both: Ni-MH travelmate 220 battery,acer btp-58a1 and lithium batteries. Since there are two types of cells exist in the market, of course, also have their advantages and disadvantages. The most obvious one, that is, we buy cell phones when they have made very clear that the Ni-MH battery cheaper than lithium batteries, its negative side is the relative size and weight of larger. Lithium batteries with these characteristics is just the opposite. As the user like lighter, thinner, longer battery maintenance of the notebook computer, so lithium batteries subject to the pursuit of more high-end products favored by the user.

    Charging techniques

    A number of lithium ace btp-63d1,acer batcl50l is equipped with notebook computers, such as the use of the wisdom of the SBS battery technology, accurate measurement of battery life, so to use up some of the worry. The use of nickel-metal hydride batteries should be careful not to over-charge frequently, or else they will reduce the battery life, so to very good control of the charging time.

    Ni-MH battery charge in the pre-discharge should be in charge should be fully recharged, the use of methods and the use of mobile phones and pay attention to issues of Ni-MH battery is the same. Bought a new nickel-metal hydride travelmate 290 battery , travelmate 4000 battery cell phone, require the completion of three fully charged and discharged after a normal start to use it, the laptop battery should also be the case.

    Most users accustomed to the use of each notebook computer, plug the AC power supply, with very little travelmate 2300 battery power for laptops. In fact, at least a month should be used to power batteries once or twice, the battery will be fully used up, followed on a one-time full of alternating current. Remember this one: rechargeable batteries, dry full charge, useful and friendly, just do it a little trouble.

    When the need to replace notebook aspire 1680 battery, preferably with a selection of models to replace the battery. However, if the old computer is to use nickel-metal hydride batteries, in order for longer battery-powered, of course, can also be specified by the computer user's manual or manufacturer's recommended selection of models of lithium batteries.

    How to set up energy conservation

    Desktop using alternating current, the majority of energy-saving features of the computer may not be very great importance, but it needs to use aspire 1410 battery-powered laptop computer, the use of energy-saving features should be taken seriously. How to design computer hardware more energy-saving, this is not a user problem to be solved. Users can do on the computer is set up on the efficient use of energy-saving options.

    Energy-saving two set-conditioning needs of users: First, the computer's BIOS setup program on energy-saving way in the set; most important thing is that the Windows 98 operating system, such as many energy-saving settings and operation. Computer systems in the practical implementation of it, Windows system should take precedence over energy-saving settings in the CMOS settings.

    1. BIOS settings in the energy-saving

    In the CMOS settings, has a large "Power Savings", which can choose to "Maximum Battery Life" and "Maximum Performance" and other options. "Maximum Battery Life" is the default mode of energy-saving settings. The notebook has several energy-saving mode, such as Idle Mode idle mode, Standby Mode standby (wait) mode, Suspend Mode suspension (sleep) mode. The notebook computer settings, have been able to regulate power consumption, mainly in energy-saving computer into the state, the timely closure of some of the equipment without the use of the system. If the state of waiting, turn off the display and hard drive; into the dormant state, in addition to the closure of the display and hard drive, memory can also save the contents of your hard disk, the entire computer system shut down to maintain the basic state, once activated, or restart the computer, desktop Will return to the precise state of dormancy before. In the energy-saving settings in the CMOS, mainly set up by Idle Mode to enter Standby Mode of the Standby Timeout time set by the Standby Mode to enter Suspend Mode of Suspend Timeout. Notebook computers use most of the Phoenix BIOS. Various energy-saving BIOS settings may be somewhat different, it should carefully read the screen prompts.

    2. Windows of energy-saving settings

    For the average user, in the Windows system for the management of energy-saving operation may have a better understanding of some simple. Windows help file, "the management of hardware and software" entries, two laptop computers and energy-related content: "Energy Management" and "the use of portable machine," "management on the laptop power supply." Energy-saving settings in Windows, you should read it.

    In the Windows "Control Panel", click "power management", will be able to open the "power management attributes" dialog box. As shown in Figure 1, "Power Management Properties" dialog box, should "use of power" set to "Portable / laptop" and reasonable arrangement "to wait for the system" and "turn off monitors," " The closure of the hard disk "option. Different computers can have some options to manipulate the differences in the new factory-to-date computer and the software will be more workable option, the details should be set up in accordance with its own computer functions and help files for Windows.

    If the need to completely run out of acer lcbtp03003 ,acer aspire 1300 power, do not look for other ways to discharge anything, only the "power management attributes" dialog box will be the "power scheme" is set to "always open" and will "wait for the system" and "shut down Monitors "and other options set to" never ", but also allows the computer automatically calculate a number of complex 3D demo program, which will soon be able to use the remaining dry battery power, of course, when these do not forget to dispose of Unplug the AC plug.

    Q: My laptop heat too, how well?

    A: The notebook computer as a result of space caused by poor cooling effect. If you use a notebook with a lock on, and with their hands thoroughly is a hot plate, because most of the heat caused by bad, you put the laptop in bed used? Notebook computer ace btp-60a1 , travelmate 240 series battery because of the need to use, the design of the power attached great importance to the management, if the statement on the notebook power management and more understanding of the serious implementation, so that power consumption could be more reasonable and effective, this notebook will have the power Less so as to distribute heat in the form of swap.

    Q: In the notebook computer using the AC when the battery machine with the need for removable?

    A: When using the AC, built-in battery is not in power, but they too are charging. Therefore, it would be better to remove the battery, this battery will be more durable.

    Q: Can long-term notebook computer using the AC?

    A: Of course it can, and I am sure that some notebooks, "lifetime" is only used alternating current.
