  Nothing like the real thing!

  Good to use an extra battery to get me through the day without plugging in. Nothing like a genuine brand battery, as the generics have never lasted long in the past! this is my second time to purchase this website; great performance;

Verified Purchase

Yes, it's original HP made in China, 4 cell,  HSTNN-LB61 - fits hp pavilion 17-fxxx series and doubtless all the others it's advertised for. Pleasant upgrade, reads about 44 watt hours full, and so added a much-needed extra hour run time over the original in my 17 inch laptop application. Low rate of self discharge.
