I just replaced my battery in my razer blade stealth and it works fine while plugged in but says charging and stuck at 97% and when I unplug it it turns off immediately and won’t turn on while unplugged. The battery is brand new. The old one was fairly bloated.

@riveteer I am certain you double-checked your work and made sure that your connectors are all properly seated and that there are no issues like bend pins etc. with those. I would contact the seller and replace the battery once more just to rule it out as the culprit.
