Safety

Charge and store vape batteries safely

Lithium batteries store substantial energy in a small space. Damage, unsuitable charging or a short circuit can cause intense heat and fire.

Check before charging

Device, cable, port and battery should show no visible damage, deformation or leakage. Damaged batteries must not be reused or opened.

While charging

Use only intended charging methods, charge on a clear non-combustible surface and supervise the process. Do not charge in bed, under fabrics or while sleeping.

Transport loose batteries

Loose cells belong in a suitable battery case. Metal objects such as keys or coins can bridge the terminals and cause a short circuit.

Battery safety

Battery safety covers selecting, using, charging, transporting and disposing of lithium cells within specification. Correct cell type, intact insulation, protected terminals and suitable charging electronics are essential; heat, deformation, unusual smell or noise require immediate cessation of use.

Safe charging

Safe charging uses only the manufacturer-approved charging method, a suitable power supply and undamaged cables on a stable, non-combustible surface. Keep device and battery observable and ventilated; unusual heat, smell, sound or deformation means charging must stop.

Safety & health

Battery case

A battery case is a non-conductive, closable container for loose removable cells. It separates terminals from coins, keys and other cells and reduces short-circuit risk; a cracked case or damaged battery is still unsafe for ordinary transport.

Thermal runaway

Thermal runaway is a self-accelerating overheating reaction inside a battery cell that can produce gas, fire or explosion. Extreme heat, hissing, smoke or rapid swelling are emergency signs: keep away, warn others and call 112 for fire or immediate danger.

Damaged battery

A damaged battery may show torn insulation, dents, corrosion or leakage and must not be used or charged. If hot, hissing, smoking or rapidly swelling, do not touch or transport it: keep away, warn others and call 112 for immediate danger; arrange collection only for a cooled, stable damaged cell.
