With the progress of technology, the battery manufacturing process is more refined and improved. More powerful high capacity batteries are manufactured for laptops of different brands. That is to say, if your original battery is 4400mah, most likely that you are able to find a 6600mah or even higher 8800mah battery for your laptop. Usually, the charge of a 4400mah battery can last for about 2 hours, while the 6600mah or 8800mah can probably last for about 4 or 6 hours.(Anyway, how long the battery charge can last mainly depends on how you use it.) No doubt that everyone will prefer the super long lasting battery. Even if your laptop manufacturer does not offer extended life battery, you can find after market battery manufacturer come up with a much higher capacity version of battery that could work with your laptop. For example, 6600mAh extended dell inspiron 1545 battery (9-Cell), while OEM (original equipment manufacturer) battery cost easily over $100+ at only 4400mAh.

Although the after market high capacity batteries are easy to find, there are still many consumers worrying about the quality of those Non-OEM replacement batteries. There is also another problem that we should pay attention. Some high capacity batteries may have a bigger size than the original standard one, because the high capacity batteries require more cells to be placed inside the battery. Anyway, considering the high prices of the original batteries, I will not hesitate to use an aftermarket dell laptop battery as long as the seller offer good return policy and good warranty on their products. Some reliable sellers can even provide one or two years warranty. Meanwhile, we could confirm the battery shape with the seller before purchase. If that is the case, why dont we consider purchasing the high capacity dell replacement battery at a cheaper price?
