Great deal, arrived fast, easy to install with included directions and provided screwdrivers . Charged fast and was up and running in no time. Highly recommend.

I have used this battery before to replace in the two ASUS UX330UAR laptops I own and I have been very satisfied with its performance and value. It comes with the necessary tools to remove the back cover and replace the battery, except it does not come with instructions. You can find suitable instructions/video online. I would also recommend having a pair of small tweezers to assist with re-inserting the battery connector clip so you can carefully finish securing the battery connector to the board with the retaining clip.After performing a proper initial discharge to 10% and then recharge fully to 100% and discharge to 10% and charge to 100% to calibrate the battery, Windows 11 reports good battery health. I also recommend the Battery Care app which also reports good battery capacity and wear details. (I typically replace this battery when the wear level is noticeable after about 2-3 years, depending on use). This can ensure that you get about 10 hours on a full battery rather than about 5 or less, enough for a cross-country airplane trip.My experience with this battery is that it is just as good performance as the OEM at a good value. I recommend this battery for the ASUS UX330UAR (or compatible) laptops.

Bought this to replace a battery in an Acer Swift 3 sf314-42. Originally when new this laptop got 8-10 hours on a charge. After 3.5 years the original battery is now giving only 3-4 hours. This replacement battery is WORSE than that and only lasted 2.5 hours from a full charge. Needless to say, don't buy it.

This battery worked very well for me. It holds a charge super well and was easy to install with the help of a YouTube tutorial. It's been almost a year since I replaced it and it's still functioning perfectly. The price was also good for the value.

I needed a battery to get my lap top back to working. This battery was perfect fit and quality

4 stars quickly leaning towards 5 stars. Solid replacement. Laptop lasts way longer than it did before. Replacement was easy. Quick video on YouTube helped out. Just be gently plugging the new battery in. Happy with it so far. Longevity of it will be determined but off to a strong start so far after a few days.

My original battery was down to about a 2-hour lifespan after 3 years. Anybody who has this laptop knows that you buy it for the light weight and the10-hour battery life, so in an attempt to stretch until I could save for a new one, I thought it'd be worth trying. Installation was very easy - I needed a miniature screwdriver set I bought at Lowe's, and a cereal bowl to drop all the screws in! So far it's been fabulous. The life might not be as much as what it was when it was brand new, but it's definitely less than a couple of days. I took it on vacation and didn't hardly use it, but had very little discharge of the battery over the course of a week so just what I was looking for. Follow the instructions on first use to discharge and recharge completely and look up the directions on Ifixit and they'll walk you through the process. (I didn't worry about static because it's the middle of summer and I have hard floors, but keep it in mind if it's drier and you have carpets etc)Everything on this laptop is still all I need, so I'm very happy that this may well keep it going for another couple years.

Battery arrived in an opened box; tape had been previously cut and it appears to have been re-labeled and re-sold... Lithium Batteries are very particular, and not being sure of the originality or condition of this battery makes it unsafe and unusable...
