Proper laptop battery usage guide
First of all it’s necessary to unfold a myth that persists in many peoples head.
The battery memory effect.
In lithium-based batteries this is in fact a myth, it only applies to older Niquel-based batteries. So fully discharging and charging the battery is completely useless and even harmful as we will see below.
The modern lithium battery can be charged regardless of its current percentage, given that it has absolutely no negative effect in its performance.
Should I remove the battery when A/C is plugged in?
Many laptop users have this question and we will answer it right now:
The answer is: YES and NO, it depends on the situation.
Having a battery fully charged and the laptop plugged in is not harmful, because as soon as the charge level reaches 100% the battery stops receiving charging energy and this energy is bypassed directly to the power supply system of the laptop.
However there’s a disadvantage in keeping the battery in its socket when the laptop is plugged in, but only if it’s currently suffering from excessive heating caused by the laptop hardware.
- In a normal usage, if the laptop doesn’t get too hot (CPU and Hard Disk around 40ºC to 50ºC) the battery should remain in the laptop socket;
- In an intensive usage which leads to a large amount of heat produced (i.e. Games, temperatures above 60ºC) the battery should be removed from the socket in order to prevent unwanted heating.
The heat, among the fact that it has 100% of charge, is the great enemy of the lithium battery and not the plug, as many might think so.
Full battery discharges (until laptop power shutdown, 0%) should be avoided, because this stresses the battery a lot and can even damage it. It’s recommended to perform partial discharges to capacity levels of 20~30% and frequent charges, instead of performing a full discharging followed by a full charging.
Laptop batteries contain a capacity gauge that allows us to know the exact amount of energy stored. However, due to the charging/discharging cycles, this sensor tends to be inaccurate overtime.
Some laptops include in their BIOS, tools to recalibrate this battery gauge, which is nothing more than a full discharge followed by a full charge.
So to calibrate the gauge, it should be performed, in every 30 discharge cycles, a full discharge non-stop , followed by a also, non-stop, full charge.
An inaccurate gauge can lead to the fact that the the battery capacity values are are wrong. The battery may report that it still has 10% of capacity when in fact it has a much lower value, and this causes the computer to shutdown unexpectedly.
Discharge (or charge) cycles consist of using all that battery charge (100%) but not necessarily all at once.
For example, you can use the laptop for some minutes in a day, using half its capacity e then fully charge it. If you did the same thing in the next day, it would be counted a discharge cycle and not two, so it may take several days until a full discharge cycle is completed.
How to perform a calibration (full discharge)?
The most adequate method to do a full discharge (100% to about 3%) consists of the following procedures:
1. Fully charge the battery to its maximum capacity (100%);
2. Let the battery “rest” fully charged for 2 hours or more. You may use the computer normally within this period;
3. Go to your Power Options in the Control Panel and configure the automatic hibernation to hibernate the computer when it reaches 3% of capacity;
4. Leave the computer discharging, non-stop, until it hibernates itself. You may use the computer normally within this period;
5. When the computer shuts down completely, let it stay in the hibernation state for 5 hours or even more;
6. Plug the computer to the A/C power to perform a full charge non-stop until its maximum capacity (100%). You may use the computer normally within this period.
To store a battery for long periods of time, its charge capacity should be around 40% and it should be stored in a place as fresh and dry as possible. A fridge can be used (0ºC – 10ºC), but only if the battery stays isolated from any humidity.
One must say again that the battery’s worst enemy is the heat, so leaving the laptop in the car in a hot summer day is half way to kill the battery.
Purchasing a replacement battery
If you intend to purchase another battery, it’s recommended that you do it only when the current battery is very degraded. If it’s not the case, the non usage of a battery leads to its degradation.
If a spare battery is purchased and won’t be used for a long time, the above storage method should be used.
Besides that, when purchasing a battery you must pay attention to the manufacturing date.
Advantages in using BatteryCare
BatteryCare allows you to have the control over the discharge cycles number, and when this reaches 30 (or other configured value), it notifies you that it’s time to perform a full discharge in order to keep the battery gauge calibrated.
Like this, it’s guaranteed to always have the correct capacity values reported by the battery.
Besides, when using the battery, there’s the possibility to suspend some Operating System features that help degrading the autonomy (only in Windows Vista or higher):
- Windows Aero, the theme that allows for visual effects like window transparency, requires graphics card acceleration, which obviously will help decreasing the battery lifetime;
- SuperFetch, ReadyBoost and SearchIndexer are three Windows Vista (and higher) services that, even in battery mode, are using the hard disk a lot and increase total power consumption, thus decreasing battery lifetime. Suspending these services has absolutely no negative impact on the performance or security of the system.
These features are resumed once the laptop is plugged in to A/C power.
Laptop Battery Buying Guide
A laptop battery provides a source of electrical energy that supplies needed power to your laptop. The laptop battery uses a combination of cells that are electrochemically active, which is to say, they naturally transmit electrons from one end of the laptop battery to the other, when those two ends are connected in a circuit. A laptop computer battery can be engineered to be highly portable, like a watch battery, or it can be built to withstand extremes in operating conditions, like a car battery.
Just like your car, your laptop computer battery lasts longer depending on how you “drive” your laptop. Modern laptop batteries tend to last three to five hours, depending on the power needs of the computer and the programs the user runs. Few things are as frustrating as when your laptop battery suddenly won’t charge fully or stops holding its charge for as long; when this happens, you’ll probably want to buy a replacement battery.
When buying a laptop battery, you will probably only have one or two choices that fit your computer. Choose the battery with the longest life available for your computer. There are several different kinds of laptop batteries; because the technologies of each are very different, a laptop must be designed specifically for the type of battery it uses. Most laptops are only designed to use one type of battery technology.
Types of Laptop Battery
•The nickel cadmium battery, known as NiCad (pronounced “Nigh-Kad”), used to be the most common type of laptop battery. Nickel cadmium batteries couldn’t hold very much power by today’s standards, and could only be charged a limited number of times. NiCad batteries could easily be ruined by being left on the charger after they had reached full charge, or by being recharged before they were completely dead. The latter problem, called the “memory effect,” meant that if you recharged your laptop battery before it had run completely down, it would remember the point at which you put it back on the charger, and only discharge that far the next time you used it.
•The nickel metal hydride (NiMH) laptop battery was the next step up from NiCad. NiMH batteries could hold considerably more power than NiCad, but they still had something of a memory effect, although it wasn’t as pronounced. Lithium ion (Li-Ion) is the latest technology for laptop batteries; although Li-Ion batteries hold about the same amount of power as NiMH, they are considerably lighter and far superior. The Li-Ion laptop battery doesn’t have a memory effect and lasts considerably longer than its predecessors. If your laptop supports multiple types of batteries, and the Li-Ion is one of them, then you should choose the Li-Ion as the best type of battery available for your laptop.
How Increase the performance of Battery?
Regardless of which type you have, it’s important to properly care for your laptop battery, in order to get as much life out of it as possible.
•”Conditioning,” which means fully discharging and then fully charging the battery, should be done at least every few weeks, as it maintains the full capacity of the laptop battery.
•Some authorities claim that this is not necessary with Li-Ion batteries, while others maintain that it’s a good idea to condition all laptop batteries regularly, rather than simply leaving them plugged into the wall at all times.
•Your laptop battery should never be stored in an area that drops below 50ÂºF (10ÂºC) or rises above 95ÂºF (35ÂºC); this means that your laptop should not be left in the car or in a storage area that is not climate controlled.
•Also, for extended storage of six months or more, the laptop battery should be discharged to 50% capacity and removed from the computer; a battery stored for an extended period of time at full capacity may lose the ability to charge fully, while a battery stored in a fully discharged state may never be able to charge again at all.

Laptop battery maintenance is essential notes and user guide
When asked about the biggest advantage of laptop time, I believe a lot of friends that it will carry portable. dell laptop battery Yes, compared to traditional desktops, the laptops in succession, while the higher operational performance, anytime, anywhere portable, a great convenience especially for business users who mainly use. The notebook’s battery, no doubt created the biggest player in the feature.
Various components in a notebook, the battery status like “evil” in the old elf, do not play a leading role, but also a vital, essential, supporting role as savior who set because it’s a good state the bad will be directly related to the laptop DC power supply in case of lack of ability to work. Therefore, learn to use and maintenance of a reasonable consumption of parts of this as an important guarantee for lasting life books. So, in the end how do maintenance on the battery? Now, let us explore it together!
The current maintenance of the existing Internet, point of view, plus a wide variety of different languages are too specialized, have let some friends watched as the children work after flooding in general, Sidongfeidong looked white look. Therefore Xiaobian that the maintenance of today’s tutorial, or should understand the impact of laptop batteries and laptop battery Dell GK479 Battery about the relevant factors.
Ah can not read can not read, do not have to specifically ask Dr. Fox bubble?
Currently, the market circulation of more mainstream notebook products are lithium-ion batteries and lithium polymer batteries. The more common before the use of nickel-metal hydride batteries and nickel-cadmium batteries, are very unfortunate to be eliminated gradually.
Lithium-ion battery (left) and Ni-MH battery (right)
Lithium-ion batteries can quickly popular and gradually Dell Latitude D620 Battery replaced the battery nickel-metal hydride and nickel-chromium the main reasons is that lithium-ion battery memory effect (assuming the battery is only half used to charge several times after they have been “memory” down, wait again when half of the battery used to “inertia” to no longer work) is not obvious, free to increase the feasibility of charging and discharging.
Of course, even if the memory effect of lithium-ion battery is not obvious, but free to charge and discharge, or will affect the life of the battery itself. More authority to the current test results, the general life of lithium-ion battery 300 to 500 charge and discharge. Therefore, the absence of special circumstances, friends, or ledge, a small temporary spare lithium precious a life now!
Moreover, even when the power is turned off the computer, the battery power is always in the state also. Once connected to the laptop external power supply, the battery will by default start charging automatically. Every time you open or turn off the power, are equivalent to repeatedly charge and discharge the battery, and friends got to bear in mind Oh!Dell Latitude D531N Battery
Lithium-polymer battery, with a large capacity battery, while thinner and lighter than traditional
As mentioned earlier, the lithium polymer battery, Xiaobian that, if no accident should be a small lithium-ion polymer after the time of the most promising successor. Lithium-polymer battery, also known as polymer lithium battery, ultra-thin compared in terms of lithium, Dell Vostro 1520 Battery large capacity, flexibility and low cost, looked really is a very attractive option.
Well, next let’s take a look at specific methods of laptop battery maintenance and operating procedures. Must have many friends from the previous discussion to appreciate, the battery charge and discharge in the maintenance of the status is very important. So first, let’s come up from the discharge to see how this issue related to maintenance.Dell Latitude D631 Battery

Universal Laptop Battery Purchasing Guide
Most people own more than one laptop unit and of different brands. Owning a universal laptop battery seems to be the most convenient way to have when you travel as it allows you to use it with any laptop computer unit when your power supply is running out.
It is true that taking care of your laptop battery is a priority as your mobile computer will be useless with a defective battery on it. There is a need to ensure that it works properly in order not to hamper your convenient usage of your notebook. Proper care of your laptop requires its storage in moderate temperature which is neither too cold not too hot. Your laptop battery will be short of power once it is cold and it will not discharge fast when it is hot. You need to frequently charge your battery to ensure it to be fully functioning well.
Going for a universal battery for laptops allows it to work on different models, brand, and units. There are varieties of choices available in most computer shops and online stores. But do know what type of universal battery to buy for your laptop?
One issue with laptop batteries is the danger of explosion. It may rarely happen but it does happen and anyone could be at risk when using poor quality battery for their laptops. Take note that lithium ion laptop batteries, which are commonly used in the market could explode owing to its cobalt oxide content.
Consideration may be directed also by choosing a laptop that is smaller in size such as ultra portable or light weight laptops. They have smaller LCD and it uses less power. It has a hard drive that runs only about 4200 rpm which uses less power than those than run at 5400 rpm. This makes your laptop battery drain less quickly.
Universal batteries for laptop use are available in different types according to the size of your laptop. A friend bought a nickel metal laptop battery which is suitable for her small size notebook. I want to buy one myself however I was advised it is not suitable for my laptop which is 16 inches. The most suitable one is the ED369 battery which is best for laptops that are 13 inches or more in size and when one uses a lot of external devices that requires more battery power. This battery provides 2 to 3 hours of power supply in normal conditions. Simply plug it into the AC adapter of the laptop and it is ready to use.
When buying a battery for your laptop always consider the size of your computer and the average consumption of power. You can choose from variable output voltage. Voltage of 16 and 19 v DC are enough to supply most laptops.
