Hello to all, I want to share some of my experience here.  Never try to greedy in shopping for low cost PC accessories. Choose the unique producer although it is expensive.

One month, yes only for one month and from this lesson I am going to never buy a budget issues for my laptop.<BR><BR>Goren<BR>--<a href="http://www.amazon.com/SterlingTeks-POWWER-Pavilion-12-Cell-9600mAh/dp/B002IFQ4FU">hp battery dv6900</a><BR><a href="http://www.amazon.com/SterlingTeks-POWWER-Pavilion-12-Cell-9600mAh/dp/B002IFQ4FU">battery for hp pavilion dv6900</a>--
