User reviews
★★★★★ The battery itself works great and has returned my "unplugged" time back to like new on my laptop. Instructions for installation are readily available on Youtube for lots of models. Taking laptops apart to install is the tricky thing, but that is not the fault of the battery folks. They did a great job. You just have to have some patience and courage popping your machine apart. Good luck
★★★★★ Videos are online. Product didn't come with instructions but I didn't expect an internal battery used in several models to provide details on a specific laptop.Never replaced an internal one before. But the price was right and I was cheaping out, avoiding a service to do the job for me.only one of the tabs to screw to the laptop was out of alignment. I was worried that I'd get the old battery out just to learn the non-OEM battery was significantly off in adaptability. Aside from having to brute force adjust one of the 6 or 8 attachment points was a pleasant surprise.Fired right up and restored 5 or 6 hours of battery ops depending on how much load you're applying.
★★★★★ Started getting the "Plugged in not charging" issue on my 3.5 years old Envy. It was barely lasting 1.5 hours and then the last few days it dropped to about 30 minutes. Opened the laptop up with a few screws, the old battery was swelling which is a sign it went bad. Took about 30 minutes to change it out. Charged it to 100% and it's like a brand new laptop.
