Buying Guide for Cheap Sony Laptop Battery

Generally speaking, a Sony laptop battery can be used for a couple of years before it completely goes dead. Then you will probably think about buying another original one from Sony distributor at a very high price. Now I would like to suggest that buying a cheap replacement battery is also a wise choice. Many people may have many questions, how do you know what to buy, from who to buy, what you even should be looking for when buying a laptop battery? I have classified several categories a person needs to be informed about when going out to make a purchase for a new battery.

 

Laptop model and original battery code (part number)

 

The original battery code (part number) is quite essential to the purchase of your new laptop battery. It is a unique identifier that is assigned to a part to simplify referencing and to unambiguously define a part within a single manufacturer. The part number above all is what needs to be known before going to buy your battery. Secondly the make and model are next most important part identifiers you must know. The make is the manufacturer (e.g. Sony, HP, and Dell). The model is a multi-component word that includes the line and actually model number. For example, the Sony VGN-FZ50B battery is an example of a Sony made laptop that is part of the VGN series and which has model number VGN-FZ50B. In other words, the information of model and part number can determine the battery compatibility.

 

Capacity, Chemistry and Voltage

 

There are series of questions about capacity you need to know before purchase: how much you want to spend, how often and how long you use your laptop on battery power, and what applications you may be running off the battery’s power. The higher the capacity the more money you will spend, so if you need the longer runtime or you use applications that require more battery power, then buy the higher capacity battery. A milliAmp hour (mAh) is the most commonly used notation system for consumer electronic batteries. For example, 4400mah, 6600mah, 8800mah.

 

Most laptops now require a lithium based battery chemistry, as it has no memory effect. You cannot choose your chemistry type for most batteries. It is still good however to know which chemistry type your battery requires.

 

For laptop batteries, the most common voltage measurements are: 7.2V, 9.6V, 10.8V, 11.1V, and 14.4V. Since you cannot choose the voltage measurement for your laptop, then go with whatever measurement is closest to your original battery. Remember nominal voltage allows for slight deviation from the original but you cannot use a 7.2V battery if it requires 14.4V. The best example would be a 10.8V battery could be used with an 11.1V battery.

 

Number of Cells

 

The number of cells is important since the more cells contained in the battery the higher the capacity will be. To determine the number of cells in your laptop battery you need to have some general idea of what cells are being used in your battery. The most common battery cell is the 18650 and is manufactured by LG, Sony, Sanyo, Samsung, Panasonic and many others. The 18650 is a 3.6V cylindrical Li-Ion cell. 18650 has no memory effect (distinguish between digital memory effect) and longer storage life than NiMH battery cells. 18650 is light weight and have a high energy density. It is in effect perfect for building batteries for laptop and other portable power devices.

 

Specifically the 18650 battery cell has a nominal voltage average of 3.7 V. It has a nominal capacity of 2200 mAh. It has a maximum charge current of 2.4 Ah and a max discharging current of 4.6 Ah. Its dimensions (DxH) are 18.3 mm (Max 18.4) x 64.9 mm (Max 65.1). It weighs 46.5 g (1.64 oz). It has cell cycle performance of 80% of initial capacity at 300 cycles. All in all the 18650 is a very good battery cell.

 

Using this common laptop battery cell as our base you can determine the number of cells in your laptop battery by doing the following. Divide the battery’s stated voltage by the 18650′s nominal voltage to get the number of cells in series and divide the battery’s stated capacity by the 18650′s nominal capacity to get the number of cells in parallel. Then multiply the results of the series and the parallel to get the total number of cells in the battery.

 

Price, Warranty and Seller

 

When choosing a seller to buy Sony laptop batteries, please first search the seller’s reputation and then carefully check the price, the warranty and the return policy. It is recommended to contact the seller if you have any questions.

Laptop Batteries Buyer’s Guide

Should you are among the rising variety of mobile executives who are switching from PCs to laptops, it really is inevitable that you simply will soon face a circumstance in which you will need to educate your self about laptop batteries. And then, at some point, acquire them. Here are some simple guidelines:

Brief Background of Laptop Batteries: The earliest sort of battery employed the chemicals Nickel Cadmium (NiCd, NiCad), and was really speedy to charge and was also in a position to manage higher loads. Nonetheless, these chemicals are very toxic. The next generation of batteries, the Nickel Metal Hydride (NiMh, NiMH) batteries, now use Nickel along with other uncommon earth metals as its electrodes and Potassium Hydroxide as the electrolyte. These are a lot more environmentally friendly than Nickel Metal Hydride, but endure from the memory effect, and have a short lifespan. A newer sort of battery will be the Lithium Ion (LiIon, Li-Ion) powered battery. In spite of becoming smaller and lighter than NiCd and NiMH batteries, it gives the identical capacity. Also, these batteries don’t endure from “memory effect” and have very low levels of self-discharging.

The Lithium Polymer Ion Battery: This really is the latest sort of battery chemistry. Although this behaves inside the identical way as Lithium Ion, you can find some crucial differences. The Lithium Polymer Ion Battery makes use of a thin plastic-like film because the electrolyte, resulting in significantly lowered bodyweight, as well as a larger energy to bodyweight ratio than a lot of the other types. They’re used in Universal Laptop Batteries. So that is the form to glimpse for, after you need to have a fresh battery for your laptop.

What are Universal Laptop Batteries?: A lot of the best manufacturers like Sony, Compaq, fujitsu, Toshiba, Panasonic, Dell, IBM, Lenovo Apple, HP, are supplying the Lithium Ion battery technological innovation. The Universal Laptop Batteries, on the other hand, use the additional sophisticated Lithium Polymer Ion chemical. A universal battery is just a greater version in the typical laptop battery, and can energy just about any laptop.

The universal batteries are rechargeable – the AC Adapter and energy lead are offered by the manufacturer. Also, the manufacturer supplies many recommendations that fit the energy supply connector around the laptop. These recommendations allow the sensible electronics embedded inside battery to provide electrical energy on the proper voltage.

A different plus stage in favor of universal laptop batteries is always that the steady utilization time is up to 10 hours at a stretch. (Not surprisingly, you’ll find variations in accordance with manufacturer and model in the universal laptop battery.)

When do I need to have a fresh battery?: You do not essentially need to have a fresh battery only immediately after the current one particular is absolutely utilised up. Some laptop manufacturers present laptops with growth slots that could accept various peripherals, which include a second battery. This second battery can double your battery existence. But, when you are organizing to have loads of do the job accomplished on that prolonged flight, then it might be time for you personally to purchase a fresh laptop battery.

Don’t forget: When buying batteries, assure that the supplier plus the manufacturer are trustworthy. Be sure that the Supplier/Manufacturer present full assure and warranty. Verify the chemistry and dimensions from the universal laptop battery just before obtain. And provide the supplier with every one of the data about your laptop this kind of because the make, the model, the portion amount, the Voltage and Existing ratings (supplied inside the guide or underside from the laptop) in order that the supplier can help you using the most suitable battery.

Proper laptop battery usage guide

Proper laptop battery usage guide

Memory Effect

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.

So:

- 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.

Battery discharges

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.

Prolonged storage

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 50ºF (10ºC) or rises above 95ºF (35ºC); 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
