Works well. Good replacement. These batteries don’t last long so you may have to replace every couple years. At least as good as the factory original.

easy to change with enclosed small screw driver and plastic tool to use. Plastic tool used to slide and pry cover off.

Fit perfectly, instantly recognized by my laptop and works just as it should. No weird issues with fitment or compatibility. Great price for a perfectly functioning product.

I bought this for my old HP Elitebook 840. I didn't buy the cheapest one, to get the best chance of success. The battery worked for a bit (1 week), but then my computer started acting very strangely, locking up and not responding. Start up was slow. I tried to troubleshoot, thought it might be an app, virus or other background process, but was unsuccessful. I finally googled the problem, and the suggestion was that the new battery was unstable. I verified by shutting down, removing battery, and restarting on plug power only. Sure enough, all back to speedy normal. So NO, I DO NOT RECOMMEND THIS BATTERY.

I had to replace my laptop battery as it was fried. This battery works perfect and was very easy to put together for my first time. I would definitely buy this one again if needed. It came in perfect condition and was perfect for my Asus Viviobook 14.

This is a great replacement for the original battery of my Dell laptop. Before buying it I was bit skeptical as to how long it will hold charge. I was pleasantly surprised. I have it for 2 months and it has been holding charge for a long time, almost the whole day.

It works well

After completing three charge cyles, the battery’s full chsrge capacity reached 39WHr, which is about 79% of its original design capacity of 49WHr. Considering its price range, the battery performance is fairly decent, providing 1.5 to 2 hours of backup time

Backup time is low, which means the battery is not original; however, it's working for time
