Hi Eleven_w,
Greetings!
Thank you for posting in Microsoft Community.
I'm sorry to hear about the bulging battery in your Surface device. Here in the Community, we're unable to access account/device details. What we can do is refer you to the designated department that handles this.
Please check the Caring for battery in Surface article at https://support.microsoft.com/help/4571474/, it states:
When batteries experience excessive deterioration, you may see severe battery life reductions or advanced expansion of the lithium-ion cells. Under normal conditions, Surface devices are designed with a mechanical enclosure to contain battery expansion. Under extreme conditions the battery may expand beyond the mechanical limits of the device and result in deformation.
Battery expansion from deterioration does not present a safety concern and is most often caused by the formation of non-flammable carbon dioxide (CO2) gas. If you have a device where the battery has expanded visibly beyond the mechanical enclosure, we recommend you stop using the device. You should handle the device with caution to prevent putting pressure on or risk puncturing the battery cell.
