MacBook Pro 14-inch Battery Service Part
The failure is caused by electrolyte off-gassing within the lithium-ion polymer cells, typically triggered by thermal stress or electrochemical degradation. This internal pressure causes the battery pouch to expand, which can warp the aluminum chassis and damage the trackpad or logic board. Replacing the battery unit restores safe power delivery and prevents further mechanical deformation of the device.
