Yes, a car battery may get warm during charging. Lead-Acid batteries usually heat up, especially when charging from low to high. Lithium-ion and Ni-Cd batteries can also generate heat, but the amount differs. Always check for excessive heat, as it may signal a problem with the battery or charging process. Excessive heat can damage battery … Read more

When a car battery charges, the lead-acid electrolyte heats up. This can cause bubbling and release gas. Gurgling or “purring” sounds are normal. However, too much bubbling may signal overheating, which can damage the battery. It’s important to monitor the battery’s condition while charging. Symptoms of bubbling include visible foam on the battery surface and … Read more
