"A swollen battery isn't gaining muscle - it's becoming a bomb. Carquest expert explains: that bulging case means internal gas pressure from overheating, overcharging, or cell failure. The plastic literally can't contain the expanding gases. 🔋 Swollen batteries are unpredictable - pressurized cases can crack without warning, spilling acid and causing fires. That heat already damaged everything inside beyond repair. Don't gamble with a pressurized acid bomb. When you see swelling, replacement isn't smart - it's survival.
