Aside from markings, appears identical to OEM battery. Boosted my battery life from 2 minutes to 5 hours.

This is a great battery. Works as advertised. Install was easy. Now to the rub: The battery reading on the ASUS laptop was 63%, always 63% after what should have been a full charge. The laptop is 3 or 4 years old, so, I was thinking time for a new battery. Purchased this battery and it only charged to 63%. Now I am not happy. After a little research I find ASUS has a setting for laptops that are plugged in all the time to help conserve the battery and lengthen the life of the battery. That setting is 63% charge. So, now I have two perfectly good batteries and a better understanding of this laptop's settings. This is a fabulous laptop and should be good for many more years and I will not have to worry about a battery.

I bought this battery for my Razer Blade 15" 2021 Advanced, and it does not appear to work. After days of charging, it still displayed a battery level of "0% and charging". The fit and finish were also suspect; some of the screw tabs came bent at odd angles, and the packaging had broken-off pieces of plastic from where the tray had fractured. The screwdrivers work, at least! Out of curiosity whether it was my repair that was at fault, I bought a different and roughly twice as expensive battery replacement from iFixit (manufactured by Boweirui(Shenzen) Information Technology Co. Ltd, while the packaging on the one I'm reviewing does not list a manufacturer), and that one worked first try. So I suspect I was shipped a defective unit.

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.

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

Design Capacity: 86.002 mWh Full Chage Capacity: 87.187 mWh

Not a very good battery. It's not even a day old and it drops 4% within 5 minutes from tasks consisting of powering the damn thing on and doing basic web browsin!! Windows is even set to battery saver mode!!! For a "brand new" battery I expect better!

Works great. Keep the cable from the old battery. My screw holes didn’t match up perfectly but if you start the middle two then angle the end ones they went in. Time will tell how long it lasts

Ottimo prodotto e ottimo prezzo perfettamente compatibile
