what should i do my battery is swelling

Question

my surface book 2 battery has been swelling and i don't really know what to do about it

Answer 1

Actually, the advice from Yuhao Li - MSFT is potentially dangerous. There is risk of fire and more if you accidentally puncture one of these batteries and it is not recommended that you try this. You also should not use this device.

Sadly, there is a history of this issue with Surface Book devices.

Also see Caring for your Surface battery - Microsoft Support - in particular "When batteries experience excessive aging, 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.

Advanced battery expansion caused by excessive aging 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."

Answer 2

Hi Felix,

The best option is to fill out the form at Caring for your Surface battery - Microsoft Support to work with a Surface Support Advocate who can provide what options may be available to you depending on the device, when it was purchased, etc.

Hope this helps,
