HP themselves did not have their own battery available for my 2-year-old Envy laptop. hp-battery[removed by editor] had the battery...a genuine HP battery...in stock and ready to ship. Shipping takes a couple of weeks, but it arrived in excellent condition. It was the exact battery, so it installed in a snap. It had about 25% power before being charged so I could instantly test that it worked. I have been using it for 2 weeks now and it works flawlessly.
