ZTHY C31N1602 Laptop Battery Replacement for Asus ZenBook U3000U UX330 UX330U UX330UA UX330UAK UX330UA-1A UX330UA-1B UX330UA-1C UX330UA-FB018R FB161T Series C31N16O2 0B200-02090000 11.55V 57Wh

We had an Asus Zenbook lying around that would not keep a charge for longer than an hour or so. Bought this replacement battery and now it works like new. The install was straight-forward with the provided tools. The hardest part was removing the back panel for the first time since I didn't realize that there were two screws hidden under the rubber feet, but the battery was easy to replace and it went back together quickly. Definitely happy with the cost vs buying a new laptop for what I intended to use it for.

The battery is the drop in replacement for the original. Value for money, fast efficient, GREAT service.

This battery fixed the following issue for my ASUS Zenbook UX330UAK from 2016 which recently developed an issue (in 2021) where it would show plugged in, when charging, but wouldn't charge past 53%. Tried doing a power drain by taking laptop's back cover off (screw removal required) and disconnecting the battery connector and holding power key down to drain power (which is sometimes helpful with strange issues - but did not make any difference in this case), also tried finding or installing the My Asus program which requires ATKACPI driver (ASUS Advanced Configuration and Power Interface Utility) to work properly - My Asus has profiles such as Full Capacity, Balanced, and Maximum lifespan - Max life span is for when always plugged in to limit the charge threshold to about 60% - but I learned this driver and software are not applicable to my particular model after visiting Asus support and drivers site so then decided to order this battery as last resort effort to fix it, and it worked perfectly. Battery is exact match for ASUS UX330UAK. As soon was I got it back together and powered it up and plugged it in it was already at 58% and then showed 1 h 40 m to full charge - then into the 60 percent range and so on. Issue resolved. Good product - I definitely recommend. Just fixed it today so can't really speak to the long term - but so far so good.

I ordered this product as a replacement battery for my ASUS work laptop. This is not the easiest battery to install but once in it charged quickly and reached 100% quickly. If you look at the product picture it includes the tools however this battery does not come with any tools so you’ll need your own. Would suggest revising the photo even though the narrative on the product shows no tools the picture is deceiving for anyone ordering it.

My OE battery was down to 16% max. charge so I replaced it with this battery from ZTHY.The new battery came at a 53% charge after installation so I let it go down to 18% before charging to condition it.I am very happy with the battery and found the process very easy. This is not a difficult process and should be doable if you have the skills to replace a screw in a pair of eyeglasses.Few general suggestions.Watch a YouTube tutorial first to get some familiarity with the process.Assemble some tools, the kit comes with the appropriate torx and Philips screwdrivers as well a a plastic prying tool (looks like a guitar pick). In addition, I suggest you have a camera bellows to remove dust and a small flat blade screwdriver to pry the hinge side rubber feet off the case.A few specific things:As I mentioned, you will need to pry the hinge side feet from the back to access 2 hidden screws underneath. The feet are held on by a sticky film and you need to get under them with something to get them started (the flat blade screw driver) and then they pull off easily.Once inside, in addition to the obvious screws, there are two battery screws under the copper tape fitting on the upper right side. One screw is covered by tape, loosen the tape to get at the screw. There are also some wires transiting the battery foot- gently lift these up to get them out of the way and be sure to push them back down during reassembly.If you are in doubt about where the battery screws you need to remove are located, look at your replacement battery for insight.The new battery cable is LONGER than the original so after replacing and re-attaching it, gently fold it over to the side- really no big deal.When putting the back on the laptop, make sure it snaps down entirely- all the way around. The back fits inside the lip of the top so you should see the lip of the case all around the back of the notebook back. Work your way around the outside edge a few times pressing down until it stops snapping and seems seated securely.Finally, you’ll need 15-20 minutes of uninterrupted time, so pick a time when you are able to do this without distractions. Also pick a clean, flat location that is well lighted.You can do this!

I bought this replacement battery for my ASUS Zenbook model UX330UAK. We followed the installation instructions exactly as stated above. Initially this battery was working fine. We left it charging for roughly 20min and saw that it went from 48% to 60%. We turned the laptop off and on and it was still ok. That night, I decided to leave my laptop charging overnight(which I normally do and have never had problems with the original battery). The next morning, I tried to turn my laptop on and it would not turn on. The lights on the sides of my laptop were illuminated along with the power button, but nothing was showing up on the screen and you can't hear the fan so I know it wasn't powering on. I held the power button down for 1 full minute and still nothing. Later that day, I decided to remove the new battery and place the old one back in(It was at 60% full charge), but the laptop still would not turn on. We also noticed that the new battery had bubbles on the surface and it was not like that the night before. I then brought it to a friend who works at Geek Squad for Best Buy to diagnose my laptop. Ultimately, he told me that the new battery I had just bought, burnt out and ultimately bricked(ruined) my laptop overall. This product ruined a perfectly good laptop.DO NOT BUY THIS PRODUCT. Contact ASUS for an original if you have to. It will cost more, but I would trust it more as well.
