CommanderEDGE | 3 Litre LFX Lithium-Ion Battery Fire Extinguisher
£146.61 (inc VAT: £175.93)
Summary
The CheckFire CommanderEDGE FX-LFX-003-ACF is a 3-litre lithium-ion battery fire extinguisher, purpose-built to tackle the unique and rapidly escalating dangers posed by lithium-ion battery fires. Unlike conventional extinguishers, which are generally ineffective against the intense heat and re-ignition risk of battery fires, the LFX uses a water-based, fluorine-free agent that discharges as an endothermic foam — rapidly cooling the battery, halting the chain reaction of thermal runaway, and significantly reducing the risk of re-ignition.
The 3-litre capacity makes the FX-LFX-003-ACF a compact and practical solution, suited to devices with battery ratings up to 300Wh. Typical applications include offices, schools, and device repair stores where mobile phones and laptops are in use, as well as workshops with cordless power tools, and domestic settings with smart tablets and similar consumer electronics. In addition to addressing the primary lithium-ion fire risk, it also provides protection against secondary Class A fires that can result from exploding battery cells.
Part of the CommanderEDGE LFX Green Range, this extinguisher is Kitemarked to BS EN3 (Class A rating), MER/MED approved, and holds UKCA and CE approval. It also carries a 35kVa dielectric test certification, confirming it is safe for use around electrical equipment. The lined steel cylinder features a corrosion-resistant finish and plastic base skirt, and comes with a 5-year warranty.

FAQs
What makes the FX-LFX-003-ACF different from a standard fire extinguisher?
Standard extinguishers such as foam, CO₂, and dry powder are typically ineffective against lithium-ion battery fires because they are not designed to handle the intense heat, rapid gas release, and re-ignition potential associated with thermal runaway. The FX-LFX-003-ACF uses a water-based LFX agent that discharges as an endothermic foam, sticking to battery surfaces and drawing out heat far more effectively than water alone, stopping the thermal runaway chain reaction at source.
What is thermal runaway, and can this extinguisher stop it?
Thermal runaway is an uncontrollable self-heating chain reaction that occurs when a lithium-ion battery malfunctions, overheats, or is damaged. It can release toxic, flammable gases and cause fires to spread rapidly through all battery cells and into surrounding materials. The LFX agent in the FX-LFX-003-ACF is specifically formulated to break down this chain reaction, cool active and neighbouring cells, and reduce further explosions and toxic gas release.
What size of devices is the 3-litre model suitable for?
The FX-LFX-003-ACF is suitable for devices with lithium-ion battery ratings up to 300Wh. This makes it well suited to environments where mobile phones, laptops, tablets, and cordless power tools are in use — such as schools, offices, device repair stores, and domestic settings.
Is this extinguisher safe to use around electrical equipment?
Yes. The FX-LFX-003-ACF has passed a 35kVa dielectric test, confirming it is safe for use in the vicinity of electrical equipment. This is particularly relevant given that lithium-ion battery fires typically occur in electrically active environments.
Is the FX-LFX-003-ACF NTA 8133 approved?
No — NTA 8133 approval applies to the 6-litre (FX-LFX-006-ACF) and 9-litre (FX-LFX-009-ACF) models in the LFX range. The 3-litre model is Kitemarked to BS EN3 (for its Class A rating) and holds MER/MED, UKCA, and CE approvals.
Can this extinguisher tackle fires other than lithium-ion battery fires?
Yes. In addition to tackling primary lithium-ion battery fires, the FX-LFX-003-ACF is also effective against secondary Class A fires — those involving combustible solid materials such as wood, paper, or textiles — that may be ignited as a result of an exploding battery.
What warranty is provided with this extinguisher?
The FX-LFX-003-ACF comes with a 5-year warranty as standard. A full range of spare parts is also available to support ongoing servicing and maintenance.
