Lithium-ion batteries are found in many common household products such as mobile phones, laptops, scooters, e-cigarettes, smoke alarms and toys.

When treated with respect and care, lithium-ion batteries are safe. However, if they are misused (for example, overcharged or damaged), or are of poor quality, they can present a serious risk of fire, explosion and toxic smoke inhalation. Lithium-ion battery fires burn fiercely, are difficult to extinguish and can spread quickly.
