Battery fit perfectly to replace original battery and it gives me about 4 hours of use so I’m very happy. Cost was much lower than others I saw in my search too

My son's Z410's original battery was at the end of its life. Decided to give the generic brand a try seeing substantial price difference. Shipped really fast and fit in perfectly. It's been about 2 weeks now and so far so good.

It works very well. Very happy with the purchase. Install is also easy.

Product works perfectly fine. As shown in the first picture(i’ll Include a 2nd one with the original battery wire attachments and a 3rd showing what I did to make the new battery wires fit the port), the only thing I had an issue was with the cable being a bit longer than the original and not being able to bend it as easily. This caused me To have A harder time/issues while trying to insert it because I couldn’t bend the cable. What I had to do was cut some of the black wrap holding the cable together so I could bend them at that angle and insert it. That was my only issue which can be fixed easily if you get A product with the wires longer and with the black wrapping thing getting on your way of bending it. Hope this helps anyone in the future so that you don’t freak out. Otherwise, it works perfectly.

baught this battery for my laptop because one it had in wasnt holding a charge & laptop ket getting hot, replaced it with new 1 & its awesome laptop last heck longer on the power & it dont get hot

The battery works great. It fit in perfectly.

Installed and left it to fully charge. It only charged up to 78% after a day of charging. Better than nothing but definitely not like the OEM one that came with computer

It fit my P500 and worked, not much else to say.
