November 5, 2026 — A Ryobi 40V 4AH lithium-ion battery reportedly popped, emitted smoke, and then ignited into a fire while sitting uncharged in a consumer’s garage. The incident highlights the severe fire risk associated with potentially defective or degraded battery packs, prompting concerns for consumer safety and property damage.
Product Details
Incident Overview
On October 19, 2026, a consumer reported a serious incident involving a Ryobi 40V 4AH battery. The battery, which was presumed dead and would not charge, had been left sitting on a bench in the owner’s garage, disconnected from any charger. Without warning, the battery suddenly popped, began smoking profusely, and immediately caught fire.
The consumer, who was fortunately present in the garage at the time, attempted to extinguish the flames with a fire extinguisher. However, this only suppressed the fire for a few seconds before it reignited. To prevent further damage and potential escalation, the consumer resourcefully used a claw device to move the burning battery onto their driveway. The battery continued to smoke and pop for a significant period even after being moved. The consumer ultimately covered the battery entirely with cat litter in an attempt to contain the incident. The report emphasized the severity of the situation, noting that if the consumer had not been home, the fire starting in the garage likely would have resulted in their house burning down.
Safety Concerns
This incident with the Ryobi 40V 4AH battery raises several critical safety concerns:
- Immediate Dangers: The sudden ignition of a lithium-ion battery presents an immediate and severe fire hazard. Such fires can produce intense heat, toxic smoke, and are notoriously difficult to extinguish with conventional methods, as evidenced by the fire extinguisher’s ineffectiveness in this case. There is also a risk of thermal runaway, where the battery’s internal temperature rapidly increases, potentially leading to further explosions or reignitions.
- Property Damage Potential: A fire starting in a garage, a common storage area for flammable materials like gasoline, paints, and chemicals, poses an extreme risk of extensive property damage. As highlighted by the consumer, had they not been present, the fire could have engulfed the entire home, leading to catastrophic loss.
- Unpredictable Ignition: The battery reportedly caught fire while simply sitting uncharged, indicating a potential internal defect or degradation that can lead to spontaneous combustion even when not in active use or charging. This unpredictability significantly increases the long-term risk, as consumers may store such batteries believing them to be inert.
- Who Might Be Affected: Homeowners, particularly those who use Ryobi 40V power tools and batteries, are directly affected. Garages, workshops, and storage sheds where these batteries are kept are at heightened risk. The entire household is in danger if a fire escalates.
What Consumers Should Do
If you own a Ryobi 40V 4AH battery, especially model 130615002DG9, or any similar lithium-ion battery, it is crucial to take proactive safety measures:
- Immediate Steps During an Incident: If a battery begins to smoke, pop, or catch fire, immediately evacuate the area and call 911. Do not attempt to extinguish a lithium-ion battery fire with water, as this can exacerbate the situation. Sand or a Class D fire extinguisher (for metal fires) can be more effective, but safety is paramount.
- Check Your Product: Verify the model number of your Ryobi 40V 4AH batteries. If you own model 130615002DG9, exercise extreme caution.
- Prevention Measures:
- Proper Storage: Store all lithium-ion batteries in a cool, dry place, away from direct sunlight, heat sources, and flammable materials. Avoid storing them on combustible surfaces.
- Avoid Damaged Batteries: Never use, charge, or store batteries that appear damaged, swollen, leaking, or unusually hot. Dispose of them immediately and correctly.
- Charging Practices: Always charge batteries in a well-ventilated area, on a non-flammable surface, and never leave charging batteries unattended. Disconnect them once fully charged.
- Disposal: Dispose of dead or damaged lithium-ion batteries at designated recycling centers. Do not throw them in household trash.
- Reporting Procedures: If you experience a similar incident, report it immediately to the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov. Also, contact the manufacturer, One World Technologies, Inc., and the retailer, Home Depot, to make them aware of the safety hazard.
