Chuwi sent me a spare battery. I installed it quite easily yesterday and now everything is fixed. The pad is usable again and flush with the keyboard. No more risk of outgassing. Finally I am relieved and happy. Thanks chuwi for the free battery.

Hey, can you say what the manufacturing date is on the swollen battery, and on the replacement you’ve just got?
How long did it take for the symptoms to show? Was it gradual or sudden?
I’m getting this laptop (hopefully delivered this week), so this would be very helpful to know.
From what I gathered so far: reports of a swollen battery seem quite common for batteries made at least until 2021-03-15. Symptoms appear gradually within 6 months but there was at least one case where it developed suddenly during or after a long-haul flight.
Yes. It seems that the problem is quite common on this model. Swelling after about a year. Gradually. The exact date of purchase, I do not know but about a year and a half.

Thank you for your reply!
I meant the date that is (or should be) printed on the battery:
All the swollen batteries I could see photos of were manufactured around March 2021. Since I’ve been considering replacing the battery straight ahead if I get an old one with the laptop I bought, I’d like to know if the problem was eventually addressed and those made more recently don’t suffer from the same issue.
Good it doesn’t happen suddenly at least.
OK. I didn’t know there was the date on the battery. I send you a photo of the old and the new. I hope this will help you.

The date of the first battery is 25 03 2021.
And honestly, I hope the problem has been fixed on the new batteries. I wouldn’t want to have this problem again. Other than that, I’m very happy with this computer. It spins very well.

And while I have a picture of the inside of my pc, do you know if the free slot is for an additional ssd or ram?
Thank you for the photos! So your swollen battery was also from around that time, quite a while ago. There is hope then that the newer ones won’t have the same problem.
Sure. The empty slot is for additional RAM. You already have 8GB soldered onboard and can add up to 32GB. The part should be a SO-DIMM DDR4-2400 (or higher). Looks more or less like this:
Ho yes… Thank you for the information.
Now I know I can add ram. And thank you for the photo of the model.

After installing the new battery did you modify something to prevent the battery problem to happen again? Do you use cooling pad?
I did not change anything. I just took off, cleaned and put back the thermal cooler. (While the pc was on open. But there was no real reason to do so.) Apparently the battery issue has been fixed on newer builds. I hope so, anyway…

Hello, all, oh, well, last year, mine had ‘swollen battery’, and got a new one, replaced in July/2022. Now, it is Jun/2023, a battery becomes swollen, again. It looks like the life of this battery is only a year.
After replacing, I put mine on a cooling pad to cool PC down, and don’t do any heavy tasks. Yet, it becomes swollen. Looks like there is no way to stop swelling…oh, boy…
That is worrying. The first battery in mine, dated 2021-03-15, has become swollen, and will hopefully be replaced. Can you say what the manufacturing date was on your 2nd swollen battery? It seems possible the faulty ones were all from March 2021 (3/15 or 3/25).
Mine was 25-03-2021, so in the list of fault ones. Crap!
fat_bird, you contact chuwi on which email address?

I contacted service@chuwi.com first. I was in Taiwan at the time, hoping they’d just ship me the part to replace on my own. But they wanted me to pay for it, which I don’t think I should have to do in the first place. I might have eaten up the cost but the quote was completely unreasonable. On top of that, for shipping, they asked 3 times what the best shipping option from China to Taiwan costs (顺丰 / SF Express).
I replied to that address with my observations but they ghosted me. So I then wrote to store@chuwi.com since that’s the contact for whoever sold me the faulty item and took my money. They don’t have to ship a part to Taiwan but they do have to handle a warranty claim in Europe. They replied and eventually arranged for the repair center in Spain to contact me. All this happened a month ago but I’ve only been back in Europe for a couple of days now, so they haven’t got the laptop yet. It’s supposed to reach them tomorrow.
Seems like the repair center in Spain are nice people, and easier to communicate with too, so hopefully it all goes well. So far it worked out better, since if I only got the power button fixed, I’d still be stuck with a swollen battery now.
Thanks for the feedback. I wonder, if they dont cover my battery issue, where it can be purchased to be delivered in Europe for a reasonable price.
@coyotefert Back when I bought the laptop, I was considering changing the battery outright, hearing all the stories.
In December 2022, service@chuwi.com quoted me (US)$20 for the battery plus $19 shipping for a total of $39. I think it’s an OK price for an out-of-warranty replacement. Not sure if it includes the VAT though, probably not.
