When it comes to getting the most from your computer, having a larger battery can give you more performance and a better experience than you might expect. While most computers come with a 4-6 cell
lithium ion battery, Dell is now selling 9-cell batteries that are designed for longer use than any battery before it. If you are searching for an extended capacity battery for Dell laptops, you do have a couple of different options. The OEM battery from dell is the first option, and is rated at 81wh, which is quite a feat compared to traditional batteries. Of course, there is also the generic 85wh battery that gives a little more power if you are willing to risk a generic manufacturer.
It's not that generic batteries are bad. In fact, you can often get better deals on an
extended capacity battery for Dell laptops when you buy generic. However, these batteries are NOT manufactured by Dell and are designed to be mass-produced which is why the price is so much cheaper. The quality might be fine, but there are generally more flaws and issues with these batteries than if you buy OEM. Make sure that if you are willing to buy generic, you are prepared for anything that might occur.
