FCL-X Fire & Safety
FCL-X Lithium-Ion Battery Fire Protection
Purpose-built for lithium-ion battery fires, from a phone on the kitchen counter to an electric vehicle in thermal runaway. The FCL-X line covers homes and shops, commercial sites, fleets, and fire departments.
Fire Suppression Industries is an authorized distributor of FCL-X™ products.
Why it works
Five Ways FCL-X Works on a Battery Fire
A battery in thermal runaway generates its own heat, releases hazardous gases, and can reignite after the flames are out. FCL-X is designed to address each of those risks.
Gets inside the battery
FCL-X soaks into the battery structure and reaches cells in thermal runaway, helping stop the chain reaction before it spreads to the next cell.
Cools fast
As a water-based agent, FCL-X pulls heat out quickly. Lower temperatures slow the reaction, contain the spread, and give responders control.
Neutralizes hydrogen fluoride
Battery fires release toxic gases, including hydrogen fluoride. FCL-X reacts with them to form non-hazardous salts, reducing the danger on scene.
Suppresses hydrogen gas
FCL-X slows the lithium oxidation that feeds the fire and generates flammable hydrogen, limiting gas buildup and the risk of secondary explosions.
Prevents reignition
A battery can reignite minutes or hours after the flames are out. FCL-X leaves a protective barrier that helps keep the battery stable.
FCL-X 20 oz
A compact, single-use extinguisher for small lithium-ion battery fires at home: phones, laptops, power tool packs, e-bikes, and e-scooters. Small enough to keep in the kitchen, under a sink, or next to where devices charge.
- Extinguisher for small fires only
- For home use; not intended for commercial or industrial use or for multi-family dwellings
- PFAS-free
- Net weight 13 oz (368 g)
Portable Extinguishers
The FCL-X handheld line runs from the pocket-size 20 oz unit to the 3 Liter model, sized to the lithium-ion batteries found in homes, shops, fleets, and commercial spaces. Larger models add agent capacity and discharge time for higher-energy batteries or places where several devices are stored or charged together.
The 20 oz, 1 Liter, 2 Liter, and 3 Liter models are single-use extinguishers for small fires.

FCL-X 2.5 Gallon / 9 Liter Extinguisher
The primary commercial format: a stored-pressure, hose-equipped extinguisher holding 2.5 gallons of water-based FCL-X solution, labeled for industrial use.
- Aim at the origin of the flame or smoke and target the ruptured area of the cell
- Inspect monthly; install, inspect, and maintain per the owner’s manual and NFPA 10
- Protect from freezing
Recharging this unit
After use, the extinguisher is returned to service with an FCL-X recharge kit: one package of FCL-X agent mixed with water in the cylinder. Recharge and pressurize per the owner’s manual and NFPA 10.
Service companies refilling in volume can use FCL-X ReCharge 275, a premixed tote that refills up to 110 of these units.

Wheeled Extinguishers
The FCL-X 50 Liter and 100 Liter wheeled units carry larger agent capacity for higher-risk commercial and industrial sites: warehouses, service facilities, charging stations, and operations that handle large quantities of lithium-ion batteries.

FCL-X ReCharge 275
A 275-gallon tote of premixed, ready-to-use FCL-X agent for companies that service and refill FCL-X 2.5 Gallon / 9 Liter extinguishers. No dilution or special equipment is required, and each tote refills up to 110 extinguishers.

Pro Max and FD Concentrates
FCL-X Pro Max and FCL-X FD are concentrates batch-mixed into water for use in tanks, pumps, and hose lines, with no special mixing equipment. Pro Max is intended for industrial environments and large-scale mitigation; each 5-gallon kit treats up to 500 gallons of water.
FCL-X FD is formulated exclusively for fire departments. It is added to apparatus tank water only: start tank recirculation at max flow, remove the lid, and empty the container into the tank. Each container makes 500 gallons of water-agent. Store between 23°F and 120°F (-5°C to 49°C).
