P10 Lite Replacement battery not charging

Recently I ordered a replacement battery for my Huawei P10 Lite to replace my aging and dying battery.

The part I ordered was https://eustore.ifixit.com/products/huaw...

After I had replaced the battery and turned it on, everything worked fine and the battery was supplying current to the device, but when I plugged in the charger, the battery didn’t charge. For 1 frame, you could see the battery indicator in the status bar switch to charging, after which it goes back to a non-charging state. The battery would remain supplying power to the device, but wouldn’t charge.

I know the issue is not with the device, since whenever I plugged back in te old battery, that one would still charge fine.

This has led me to believe the issue is with the replacement battery.

What I also noticed with regards to the battery, is that the model that was included in the fix kit has “SD-HW-P9PLUS” written on the flex cable to connect the battery, while this model isn’t included in the compatible devices list on the store page.

Furthermore, the flex cable has a different shape/length to the one listed in the store page and the one in my device. (See included pictures.)

What can I do to resolve this issue? Was the battery supplied in te repair kit an incompatible part for my device?

Thanks in advance!
