Purchased this battery to replace the factory battery that was so dead that the computer would not even recognize it. Replaced it with the ordered battery and found it to be already at 50% (which was very nice) and booted the machine. No issues with charging. One other plus is that this is a high capacity battery when compared to the original factory battery, so I get more run time. Very satisfied.

The delivery of the Laptop Battery was very quick, I received it within 2 days of order. The battery fit perfectly to my laptop and was already 50% charged when I received it. It is working great and the price was very reasonable. I would buy again from the vendor.

This battery gives better than the Genuine battery I had. 4.5 on easy use and 3.5 on hard use of laptop.

Got the delivery in 2 days. Have been using the battery for about a week. It works really well, about 4-5 hours after charging to 100% with regular web browsing like Youtube, Facebook, etc. It is a 58Wh battery.

Quickly delivered. And the product works well.The battery charge well and exhaust a little qukcly then expected, but still works for a while.The seller is quite responsble, asking feedbacks and provided a full year warranty.

I never even opened the product. The mistake was on my side, I didn't check the specifications that it's not compatible with my laptop.

Has perfect fit. Easily lasts 6 hours. I generally don't have to run longer then that. I Don't give out many recommendations. But I would Recommend these Battery Packs!

Product that works from Amazon seller
