after 2 years my original HP battery cannot operate normalliy. It was a six cell battery and even at its best and with every power saving function turned on I was lucky to get more than an hour. The replacement 12 cell battery will run well over three hours even with everything running at full power. Quite an upgrade and the price through batterystyle was exceptionally low when compared to buying through the HP site. The extra bump out for the additional cells makes for a little bit of awkward handling when on your lap, but actually places the keyboard at a nice angle when on a flat surface.

I have been using the battery for 2 1/2 years and it still retains +/- 90% of it's original life.thanks a lot.

this item arrived fine. It took a while from China. My computer says that it is good for about 2.5 hours, which is better that the original. Good purchase!!

this tiem is the fourth battery i have bought in 18 months.until this one, it could last for longer time using.although it was charged much more expensive than my last three batteries.

this battery saved me much money. it is a great deal. i wish this battery could accompany longer than my last one. let time tries.

Great product and price. Seems to keep a 4.5 hour charge better than my old battery that only had a two hour charge. highly recommended.
