• Thermal runaway: Can lead to fire or explosion if the battery is abused (overcharged, overheated, punctured). • Deformation: Swelling or bulging indicates internal damage and potential hazard. • Gas release: Damaged batteries may emit hazardous gases.

• Immediately stop using the device. • Do not attempt to puncture or compress the battery. • Move the device to a non-flammable surface away from flammable materials. • Contact your device manufacturer or a certified e-waste recycler for safe handling and disposal.

• Use only manufacturer-approved chargers and batteries. • Avoid exposing devices to extreme heat or direct sunlight. • Do not overcharge or leave devices plugged in unnecessarily. • Regularly inspect devices for signs of damage or swelling. • Install IONSNIFF – a lithium-ion detection sensor – in your home or device storage area

• Never dispose of batteries in regular household waste. • Use certified battery recycling programs or local e-waste collection points. • Store used batteries in a cool, dry place away from metal objects until recycling. • Tape battery terminals to prevent short circuits before disposal.

• Swelling, bulging, or deformation of the battery or device. • Unusual heat, even when not charging or in use. • Leaking fluid or strange odors. • Device malfunctions or sudden power loss.

• Evacuate the area immediately. • Use a Class D fire extinguisher if available, or sand to smother the fire. • Do not use water unless specifically recommended for the battery type. • Call emergency services.

• Prevents environmental contamination from toxic battery materials. • Reduces fire risks in waste facilities. • Supports recovery of valuable materials for reuse.
