Things You Should Know About Cheap Laptop Batteries
Laptop has become very important in our lives, so that the power source also very important for efficiency and survival of our laptops. If the laptop cannot be used for more than two hours the user will get stuck with a device created for speed and mobility but shut down very quickly because the electricity supply is inefficient.
There are many types of batteries such as nickel hydride, lithium ion batteries and nickel-cadmium batteries. Batteries price depends on the materials used to manufacture them. Among these three batteries, nickel cadmium batteries are the cheapest. The price of nickel cadmium batteries can range from $ 50 to $ 100.
Nickel hydride battery is a little expensive compared to the cadmium batteries. The price of nickel hydride batteries can range from $ 80 to $ 150. A lithium polymer battery is more expensive than the two types of batteries mentioned above.
Another discovery is revolutionizing the laptop battery is a new external battery that offers run-time of about seven hours in about half the price, but also depends on the programs used on a laptop. Many vendors on the internet offer cheap laptop batteries when purchased in large quantities.
Some companies offer a discount on the battery if the same company that produces laptops. Alkaline batteries are the cheapest among batteries, but bear the highest cost per cycle. Other cheap laptop batteries include lithium ion batteries and lithium ion polymer batteries. Cheap laptop batteries are also available in the Chinese market and can be sent to the United States with reservations over the Internet.
Life of a battery can be increased about fifty percent, so lowering the same price. Many preventive measures can be taken in order to increase the battery life like – fully discharging and charging the battery at least once a month back, the battery remains cold and dry, and make sure that the battery is not overcharged.

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.

The way to use the cheap laptop battery as an expensive one
What happens when you buy a cheap battery that quickly loses its kick? You don’t want to have to go out and buy another battery, then you will have spent more than it would have cost to get a good one originally. Or maybe you already have a really good laptop battery and you just want to keep it running at its peak performance, to prevent a future purchase. Either way you need to know the secrets to extending the life of that laptop battery such as Original HP Pavilion dv8000 Battery 8 cells 4400mAh, and I am going to share them with you.
So what exactly can happen if you don’t take care of that cheap laptop battery?
just follow the simple tips .
Don’t allow your laptop battery to discharge completely. Allowing a battery to completely discharge can have very negative effects on the overall performance and life of the battery. Often times we find that by draining the battery can in some cases cause complete battery failure or drastically shorten the charge capacity of the battery. What this means in plain English is your battery will die and/or not hold as much of a charge therefor draining quicker than it should.
Many manufacturers recommend that your battery is stored and maintained at around half or 40% charge to maintain optimal performance. Always read the user manual that came with your laptop, or if it is a replacement battery read the included documentation.
Add more memory or RAM to your laptop. Many people would speculate that this method will not help to save battery performance due to the fact that more memory requires more power to maintain. While this reasoning is true in part, if your laptop is short on RAM, your hard drive will be constantly running to make up the difference, via your swapping file, which in turn would use a lot more power and battery life. If you are using a laptop that has say 512mb of RAM, increasing this to 1gb should be more than enough to maintain optimal performance.
Turn off your Wifi while not in use. There is usually a switch to turn off your Wifi, however you may need to turn it off in the Wifi configuration panel. Your Wifi uses a lot of power when it is not connected because it is constantly searching for a connection, so it is a good idea to make sure it is turned off when not in use.
Remove your battery while running your laptop on AC. If you are working from home and your laptop is plugged in to the AC, removing your battery is a good habit to have. Keep in mind that you do not want to store your battery completely discharged, but this method will allow your laptop battery to take a break while not in use.
Take care of your battery and keep it clean. I should probably say this twice, but I won’t. Taking care of your laptop battery is crucial to its performance. Over time the metal contacts on the battery will build up gunk that can cause the battery to work harder than it should in its daily operation. So once a month, pull out the battery and wipe it down with a cloth, clean off the contacts and you will extend its life.
Lower your graphics use. You can save a lot of power consumption by dimming your screen, lowering the screen resolution and removing the fancy graphics. Windows especially uses a lot of graphics on the menu’s and such, which is easily turned off and cut out a lot of the battery drain. The overall look may not be as pretty, but were going for battery life here.
Remove USB devices when not in use. Usb devices often require a good amount of power to continue running. If you are not using them make sure to remove them from the computer and this will help to save on battery consumption.
Defragment your hard drive regularly. Defragmenting your hard drive can help it to run more efficiently and require less power consumption. The more efficiently your hard drive operates the less work it will require to maintain operation. So keeping this in order and defragmenting regularly will benefit the life of your laptops battery.
Keep your laptops air vents clean. Laptops, or computers in general operate more efficiently when running at cooler temperatures. This is also why you see high end computers with water cooling systems. Anyways, by keeping the air vents clean you allow more air flow for the fans to run and the laptop will remain considerably cooler.
Optimal laptop performance causes optimal battery performance. Over all, the better your laptop performs the longer your laptop battery will last. It is very disruptive to your day when your laptop battery dies and you are constantly looking for a good place to plug in. So use the tips above to maintain your laptops battery at peak performance and life on the go should be a little easier.
Set your laptop to hibernate rather than stand-by mode while sitting idle. While stand-by mode is great for saving on power consumption, setting your laptop to hibernate will allow the computer to completely shut itself down and still save your laptops state where you left off. Both options are good, you should at least be doing one of them, but hibernation will be the most effective.

Laptop batteries are made up of different varieties of chemical compounds and which ones go into the making depends from one brand to another. The basic process behind the generation of power or energy is the same in all the laptops; as a matter of fact the chemical compounds in the batteries react with each other resulting into the conversion of chemical energy into electrical energy. Out of the several types of laptop batteries, the most popularly used ones are—Lithium-ion batteries, Nickel-Cadmium batteries and Nickel-Metal Hydride batteries.
Lithium ion (Li-ion) based batteries are the most widely used in laptops nowadays because it is lighter in weight and more durable than others. Cheap Laptop Battery is free from ‘memory effects’ which means that they do not have to be fully charged in order to have a full charge next time. Batteries made from lithium-ions deliver superior performance in comparison to others. Li-ion batteries are flammable thus naked exposure of these batteries in the open air may pose environmental hazards.
Nickel-Cadmium (NiCad) batteries are economically priced and possess high discharge rate with longer life. Besides this, it is one of the oldest cell types which are generally found in outdated laptop models. The popularity of these batteries suffered a setback on account of ‘memory effect’ therefore special care is required if one has to utilize it with high efficiency.
Nickel-Metal Hydride (NiMH) batteries differ from Nickel-Cadmium ones in some ways. NiMH batteries have 30% more capacity than the latter and also have less toxic substances. Batteries built from these are commonly used in laptops and they are cheaper than Li-ion batteries. This type of battery cell is very prone to memory effect and also Cheap Laptop Battery which means that laptop users must take good care in order to enhance the optimum run life.
Now, it will be fair to judge why the prices of laptops differ as the make and the model improves. The type of cells used in the making of the laptop battery has thus become a prerequisite in the pricing of the batteries. Cheap Laptop Battery from uncertified dealers can be a cause of alarm for any buyer considering the fact that low quality cell components are capable of breaking the functions of the system.
