Lithium-Ion Fire Extinguishers: A Guide for E-Bikes, E-Scooters & EVs

E-bikes, e-scooters and electric vehicles have brought lithium-ion batteries into more Australian homes, garages and workplaces than ever before. These batteries are safe in the vast majority of cases — but when one fails, the resulting fire behaves nothing like a conventional one. It burns hot, can reignite, and a standard household extinguisher often won't address the real problem. The right extinguisher is designed for exactly this scenario.

This guide explains why lithium-ion battery fires need a purpose-built extinguisher, what our 4L EV Fire Extinguisher does, and how it fits into a complete fire safety plan.

Why standard extinguishers fall short

A lithium-ion battery fire is driven by thermal runaway — a self-sustaining chemical reaction inside the cells that generates intense heat (temperatures can reach around 1600°C) and releases toxic, flammable gases. The fire is fuelled from inside the battery, which is why it's so persistent.

Standard ABC or CO₂ extinguishers are not formulated for this. They may knock down visible flames for a moment, but they don't cool the battery or interrupt the underlying reaction — so the fire can flare straight back up. A purpose-built lithium-ion extinguisher works differently: it's designed to cool the battery and interrupt the thermal runaway process, helping to reduce the chance of re-ignition.

Inside the 4L EV Fire Extinguisher

Our 4L EV Fire Extinguisher (suppression unit) uses an advanced formulation engineered for the high-temperature, volatile nature of lithium-ion battery fires. The 4L size is a practical middle ground — light enough to handle easily, with enough capacity for real situations.

• Capacity: 4L — ideal for e-bikes, e-scooters, mid-sized EVs and home use.
• Purpose-built formulation: Designed to cool the battery and interrupt thermal runaway, helping to prevent re-ignition.
• Standards: While there is no specific Australian Standard for lithium-ion battery fires, this unit complies with the European and international standards EN‑3‑7‑2004 and A1‑2007.
• Lightweight and portable: Easy to store and quick to deploy when it matters.
• Warranty: 12 months.

It's also available in 1L and 9L sizes — the 1L suits smaller vehicles or tight storage, and the 9L is geared towards larger EVs, commercial use and fleets.

Who is the 4L extinguisher for?

• E-bike and e-scooter owners charging devices at home — one of the most common settings for lithium-ion fires.
• Households with an EV or hybrid parked or charged in a garage.
• Small workshops and businesses that service or store battery-powered equipment.
• Fleet operators wanting a portable unit at each charging point — see our fleet fire safety resources.

How to use it — and what it won't do

If you ever face a small lithium-ion fire in its early stages, and only if it is safe to act, follow the PASS method:

• Pull the pin.
• Aim at the base of the fire, or the battery area.
• Squeeze the handle.
• Sweep from side to side, focusing on cooling the battery pack.

A few principles matter just as much as the technique:

• Always call 000 first. This extinguisher is designed to help contain and control a fire until emergency services arrive — not to replace them.
• Only act if it's safe. If the fire is large, spreading, or you're unsure, evacuate and wait for the fire brigade. Your safety comes first.
• Expect reignition. A damaged battery can reignite, so treat the area as hazardous until firefighters confirm it's safe.
• Maintain it. Check the pressure gauge sits in the green zone, the pin and seal are intact, and inspect for damage. Have it serviced per the manufacturer's specifications.

Build a complete EV fire safety plan

An extinguisher is most effective as part of a layered approach. Many homes and workshops pair it with an EV fire blanket to contain larger fires and battery containment bags for damaged batteries and smaller devices. The right mix depends on what you're protecting and where.

Being prepared is about having the right equipment ready before an emergency — not searching for it during one.
