iFixit replacement battery faulty?

I ordered a replacement battery for my Lenovo Yoga X1 Gen6 (Lenovo ThinkPad X1 Carbon G9 & Yoga G6 Battery - L20C4P71). Installation was no problem but after the first charge to 100%, I noticed that my laptop wouldn't go to sleep normally: it immediately shut down and then rebooted. The Windows log file showed a 41 kernel error code. After reinstalling the graphic card drivers (as per advice on a Lenovo forum), I used the laptop until the battery was drained. I did notice it went from 50% to 15% in under 15 minutes while just browsing the web. The laptop then shut itself down.

I attached my original 65W Lenovo charger and started to charge the battery but noticed the battery was charging very slowly (at 2W max). After four hours, it had only reached 50%. I then used an Anker 65W charger, but the slow charging problem remained. I decided to reinstall my original Lenovo battery (which has lost 20% of its capacity) and all works well again.

I suppose I have received a faulty battery but is there anything I could check before I ask for an RMA with iFixit?

Hi @bjoernisebaert

Go to Device Manager > Battery and uninstall the Microsoft ACPI Control Method battery drivers.

Once they have been uninstalled, close any open windows and then restart the laptop in the normal manner.

During the following startup, Windows will reinstall the battery drivers.

Doing this will forestall any problems with the OS possibly not recognizing the battery so that it will work correctly etc.

Fully charge the battery and then create a battery report to view the status and condition of the battery.

Once you have the report, compare the Design Capacity value versus the Full Charge Capacity value as shown in the report. For a good new battery they should nearly be the same value.

If not you can work out the condition of the battery as a percentage, using the formula Full Charge Capacity value x 100 ÷ Design Capacity value.

Thanks for your advice. I started as you instruct, but as soon as I had replaced the battery and wanted to boot my computer, I got a short flash on my screen, then nothing. Disconnecting from AC didn't make a difference: my computer won't boot with the iFixit battery anymore. I managed to order an original Lenovo replacement battery last night, which arrived today and this one works flawlessly. Guess I'll have to contact iFixit support then ...

Yep.

According to the battery link you posted in your question, there's a 30 day return policy and also a 1 year guarantee, so you shouldn't have any problems with ifixit about a refund

Update: I contacted iFixit support and they could send me a replacement battery or refund my purchase. I opted for the latter and I have already received the refund. I have to say that I was very pleasantly surprised by the speed and helpfulness of the support!
