This brought my HP Envy360 laptop back to life. I did buy my laptop a long time ago so either the battery was just old or developed memory I don't know, but it only lasted a couple hours on battery power regardless of what I was using it for. Even though my laptop is older it has amazing specs and works flawlessly except for the battery life so I decided to change the battery instead of buying a new laptop and ended up picking this one really because there was a one day delivery option. The Envy360 is a 2 in 1 laptop and they are thin so getting to the battery was interesting because the screw sizes were very tiny. This battery came with the tiny screwdrivers which is a plus but I used my tiny power screwdriver which saved time. I changed the battery successfully and it works great. To test the battery life I went to a web page that plays videos and left it running continuously. It took 7 and a half hours before the battery died without using any battery saving options such as dark mode, etc. It's a high definition screen and I had the "brightness" fairly high as well. I think 7.5 hours like that is pretty good. The only thing about the battery is that it arrived with one of the screw anchors on the battery itself bent. I was nervous about straightening it out to screw it in because the anchor is so thin and I was worried I might break it. I didn't break it. The battery was well packaged so not sure why it would be bent but no harm no foul. I would definitely recommend this battery. Worth the price.

Its perfect and this one is bigger than the last one so far zero issues

Outstanding! My laptop battery was dying, but the 8 year old laptop was still excellent for my uses. For under $40 it’s now like new, with hours of runtime vs minutes. Easy installation. Perfect all around.

It seems to be an exact match, went into place easily, and so far (only a few days), working correctly and for about the same number of hours as the original when new. No complaints if it doesn't wind up degrading in a few months.

Purchased this replacement battery hoping to give my laptop some extra life, but unfortunately it only lasted through about three full charges before completely failing. The battery now will not charge at all or power the laptop. Installation was straightforward, but the reliability was very disappointing. I would not recommend this product based on my experience.

Working good

Overall, so far, so good. Main problem was that the screw holes didn't line up with the battery and one of the screw loops was broken and not fully operational. Not a big deal but it bothers me that they didn't line up. That's too easy from a design perspective to get right, and if they can't get the screw holes to line up, who's to say they got the battery itself is reliable? Anyhow, my last battery would die after a minute or two but with this new battery, has burned in for about 30 minutes and is still at 75$ and it says I have about 1h 40 minutes left on battery, which is great. These gaming laptops (Alienware R17) really suck power down so this will work. I hate it when I'm teaching with this laptop and it dies if I disconnect from power. Value is good, not expensive, installed mostly ok, can't really track heat but the motherboard will shut down if it gets too hot anyway. Battery size is normal b/c it fit into the laptop. Overall, good deal. Hope it lasts. If it fails early, I'll post about it here to save others from wasting their money.

Need a little technical/mechanival experience but worked great

Produit conforme à la description

Gerät läuft nur mit Netzanschluss, der Akku lädt einfach nicht, wird mit 0% angezeigt. Update: Ich habe das Gerät noch einmal auseinander genommen und den originalen Akku wieder eingebaut. Damit funktionierte das Gerät, lud auch auf, hält aber nicht lange, weshalb ich ja den neuen Akku bestellt habe. Nochmal geöffnet und die Akkus wieder getauscht und siehe da... er lädt. Ich erhöhe also von 1 Stern auf 5 Sterne.
