Welcome to a laptop battery specialist of the Asus Laptop Battery First post by: www.itsbattery.com When buying a battery for your notebook , firstly should look for is the respectability of the item at mind. If the product is made by the manufacturer of your laptop (i.e. Sony, Compaq, Dell, etc),you can be sure about quality. However, alll brands doesnt produce their battery by themselves. For example, when you open Sony laptop battery, you might find that the power cells inside are actually made by Toshiba, Panasonic, or a similar brand company. Here, u can understand Sony produce only plactic box of this battery Many third party brands use the exact same power cells as original manufacturers.Using a third party manufacturer is often a good way to go when buying a battery such as Asus A42-A3 Battery, as there are usually many extra benefits. For instance, most third party batteries are much lower in price than original manufacturers batteries. Secondly, they usually grant a superior warranty, as they realize that in order to win the consumer's respect; they must stand behind their product. A 1-Year Waranty is a must. Dont buy any battery with a warranty less than one year. Batteries have been known to end its life early, and 3-Month Waranty could leave you high and dry.the next important thing you should look for is the type of battery. Batteries can be made using several chemicals. For laptops, there are four main types. They are Ni-Cad, Ni-MH, Li-Ion, and Li-Poly. There is no major manufacturer that still makes Ni-Cad laptop batteries, as they are a very old and simple type of power. Ni-MH is newest and more advanced, but is not as good as its Li-Ion and Li-Poly counterparts.If we compare the last three types (Ni-MH, Li-Ion, Li-Poly), we find that Ni-MH batteries weigh more than the other two battery types, but produce less current than the other two. Li-Ion and Li-Poly are the most advanced types of batteries on the market, and you should try to get one of these two types if its possible. Most laptops that come with one type of battery can not use any other type of battery, if u use ni-cad battery , you should replace it with a ni-cad battery. please be carefull about it, this does not apply. Some laptops that come with a Ni-MH battery can be replaced with a stronger Li-Ion one.Lastly you must be aware of the power rating of the item you are buying. As technology advances, so do power ratings. The battery you bought last year may be twice as strong this year, and might even be the same size. Batteries have two main ratings on them: Volts and Amperes. ,most companies indicate their ratings with Volts and Milliamperes. 1000 Milliamperes = 1 Ampere.When buying a battery, always look for the battery with the most Milliamperes (or mAh). Batteries are also rated by Watt-Hours, perhaps the simplest rating of all. This is found by multiplying the Volts and the Amperes together.http://www.articlesbase.com/laptops-articles/what-should-you-look-for-when-buying-battery-4511963.html
