Product Details
Incident Overview
On December 10, 2025, an incident was reported concerning a Greenworks 40v 16″ Brushless Cordless Push Mower. The consumer reported that the lithium battery of their Greenworks mower ignited, resulting in a fire in their home. The specific circumstances leading up to the battery ignition, such as whether the battery was charging, in use, or in storage, were not detailed in the initial report. The incident highlights the potential fire hazard associated with lithium-ion batteries in consumer products.
Safety Concerns
The ignition of a lithium battery poses several serious safety concerns for consumers and their property:
- Immediate Dangers: An ignited lithium battery can rapidly escalate into a full-blown structural fire, causing severe burns, smoke inhalation injuries, and potentially fatal outcomes for occupants. The sudden nature of such fires often leaves little time for evacuation.
- Long-Term Risks: Beyond immediate harm, property fires can result in extensive structural damage, lead to long-term displacement, and cause significant emotional and financial distress to affected families. Smoke and soot damage can permeate an entire home, requiring extensive remediation.
- Who Might Be Affected: Homeowners, their families (including children and the elderly who may have reduced mobility), and pets are all at direct risk in the event of a home fire. Neighbors and emergency responders could also be affected by the spread of fire or related hazards.
- Property Damage Potential: As reported, the incident led to a home fire, indicating a high potential for substantial property damage, including destruction of personal belongings, structural compromise, and the need for costly repairs or even complete rebuilding.
What Consumers Should Do
If you own a Greenworks 40v 16″ Brushless Cordless Push Mower or any product utilizing similar lithium-ion batteries, it’s crucial to be aware and take precautions:
- Immediate Steps in Case of Fire: In the event of a battery fire, prioritize safety above all else. Evacuate everyone from the premises immediately and call 911. Do not attempt to extinguish a lithium-ion battery fire with water, as it can react violently. Use a Class D fire extinguisher if you are trained and it is safe to do so.
- How to Check if You Own the Affected Product: Verify the brand, model, and voltage of your cordless push mower. Look for “Greenworks 40v 16″ Brushless Cordless Push Mower” on the product labeling or in your owner’s manual.
- Prevention Measures:
* Always use only manufacturer-approved batteries and chargers specifically designed for your product.
* Do not overcharge batteries; unplug them once fully charged.
* Store batteries in a cool, dry place away from direct sunlight, heat sources, and flammable materials.
* Inspect batteries regularly for any signs of damage, swelling, overheating, or unusual odors. Discontinue use immediately if any of these are observed and dispose of the battery safely according to local regulations.
* Avoid dropping batteries or exposing them to impacts.
* Do not leave charging batteries unattended, especially overnight.
- Reporting Procedures: If you experience an incident involving a Greenworks product or any consumer product, report it immediately to the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov. You should also contact the product manufacturer directly.
Manufacturer’s Response
Sunrise Global Marketing / Greenworks Tools has provided a response to the incident report dated December 31, 2025. Greenworks states that they “take this matter seriously and are actively investigating the consumer’s allegations.” However, they also noted that “Greenworks cannot confirm that a Greenworks product caused or contributed to the reported fire or resulting damage” at this time. A laboratory examination of the subject product is being arranged as part of their ongoing investigation, and an update will be provided to the CPSC upon its completion. Greenworks also highlighted potential “spoliation issues” as the fire scene and surrounding materials were cleaned and altered before they had an opportunity to conduct an inspection, which they state “may limit the ability to determine causation.”
