"Swollen battery = immediate danger zone. That bulging case is internal gas pressure from damage that's turned your battery into a pressurized container. Swollen batteries can crack without warning, releasing acid and toxic gases. 🔋 Swelling means irreversible internal damage - heat destroyed the chemistry and structure.
