Direct fit, works well

So far, this battery works flawlessly as a replacement for my Acer Nitro 5 battery. The battery life is also great and like it was when my laptop was new. I recommend it 100%

The battery was exactly what I needed to replace my old laptop battery. Fast shipping and great service.....thanks.

Bought this for my Acer Aspire One 0756. Fits perfectly although as some others have stated it sticks out from the bottom a bit as it is a 'high capacity' battery and the laptop will sit at a bit of an angle with the battery installed instead of 'flat' like the one included with the laptop. The good news is that this battery does work and gives longer life than the one that comes with the laptop from the factory which on mine was rated at 2,500 mWh. Upon doing a battery report under Windows 10, which I have installed on my Aspire One the 'design capacity' is listed as 57,720 mWh but the 'actual' charge capacity is listed as 44,389 mWh. I did two battery run down tests so far from full charge and found that on very light usage with display at about 3/4 brightness I got about 4.5 hours of battery life. The second test I used the laptop a bit more...surfing a number of websites, watching several youtube videos...and the battery life reduced to about 3.5 hours. This is compared to about 2 hours on the battery that shipped with the laptop which has roughly a little less than half the stated mWh battery charge capacity according to the Windows 10 battery test. So while this battery is not going to get you 7 or 8 hours of use I'd still rate it a good value because of the great $18.49 price. I did one more test before I published this review and charged the laptop to full and then reduced the screen brightness down to about 25% and literally did nothing on the laptop. I wanted to see how it would fair if it were being used just to read contents on the screen. The laptop lasted 6.5 hrs this way before automatically shutting down. Not bad for an under $20 battery. But realistically if you're gonna use this battery normally with brightness up 3/4 and typing on it, surfing the web etc...i'd expect to get around 3-3.5 hours from it.

Works well so far, if there is no update then I had no issues since the date of this review. Way cheaper than an OEM battery replacement.

Battery arrived with 50% charge and fit perfectly in my HP envy x360 15z-ds100

The part number and everything suggests it should fit my laptop, it looked the same as my old battery, all the details matched. Swapped it in, charged it once, and then it immediately died for good, and took out my drivers in the process. Luckily I was able to salvage some of my important files, but I had to use my old battery to do a new windows installation. This one didn’t let me go past the endless restart loop, didn’t work with a restore, didn’t connect to internet for troubleshooting, nothing. I wasn’t expecting a battery replacement to mess things up so much that I’ll have to waste a precious weekend.

Perfect replacement
