Battery Safety
Both types of batteries come with their own risks. Lithium-ion batteries can overheat, catch fire, or even explode when damaged or improperly used. They may show early warning signs such as swelling, excessive heat, unusual odors, hissing, cracking noises, or even smoke. On the other hand, 9-volt batteries—featuring both positive and negative terminals on the top—are particularly prone to sparking if they come into contact with metal objects, especially when stored near flammable materials.
