i have been using the battery for a little over a month now and I am generaly happy with the results. The power lasts at least as long as the OEM Dell battery did when it was new and it appears to be working just fine.
wish the shipping speed could have been faster.

this battery is more powerful than the stock HP battery and so far it is giving me over 4hrs30mins of continuous use. The price was very reasonable compared to the other replacement batteries. I received the shipment within few 4 days.
