A leaking LiPo battery is often a warning sign of a deeper reliability issue. For OEM products, battery leakage can damage electronics, increase warranty costs, and cause unexpected field failures. The root cause is not always the battery itself. Product design, charging conditions, operating temperature, and manufacturing processes can all

 Swollen Li-Po batteries are not random defects. The swelling results from electrochemical side reactions that generate gas inside the cells. Unlike cylindrical Li-ion cells, Li-Po batteries use a flexible aluminum-laminated pouch. As gas accumulates, internal pressure increases until the pouch begins to swell.  Gas generated inside the sealed cell increases
