December 18, 2025 – A recent incident report details a consumer’s alarming experience with a Flex Power Tools Lithium-Ion Battery Pack, model FX0111, which began oozing a black liquid. This incident raises significant safety concerns regarding potential chemical release and fire hazards associated with the battery, along with questions about the manufacturer’s responsiveness to consumer safety reports.
Product Details
Incident Overview
The consumer purchased a Flex Power tool kit, including a drill and an impact driver with two batteries, from Lowes approximately two years prior to the incident. In August 2025, one of the two Flex Power Tools Lithium-Ion Battery Packs (model FX0111) reportedly started oozing a black liquid. The consumer immediately reported this issue to Flex Power Tools, the manufacturer, and was issued a return authorization for a replacement battery, which was never received.
Following the initial unresolved report, the consumer contacted Flex Power Tools again in October 2025 to report not having received the replacement. Despite a promise to send another replacement, it also failed to arrive. The consumer expressed serious concern about the safety of the product, stating that the company appears to have “issues with Lithium batteries that pose significant risk” and is “giving a run around to customers.” The consumer is now apprehensive about keeping the second, unaffected battery in their home due to fears of chemical release and fire hazards, and believes Flex Power Tools is “unwilling to deal with this issue.”
Safety Concerns
The oozing of black liquid from a lithium-ion battery pack is a critical safety concern, indicating a potential internal malfunction or damage that can lead to severe consequences.
- Immediate Dangers:
* Chemical Exposure: The black liquid could be an electrolyte, which is corrosive and can cause chemical burns upon skin contact or irritation if inhaled. Direct contact with eyes can lead to severe injury.
* Thermal Runaway and Fire Hazard: Leaking or damaged lithium-ion batteries are at high risk of experiencing thermal runaway, where an internal short circuit causes a rapid and uncontrollable increase in temperature. This can lead to the battery catching fire, exploding, or releasing highly toxic fumes. Lithium-ion battery fires are particularly dangerous as they can be difficult to extinguish and may reignite.
* Short Circuit: The damage causing the leak could also lead to a short circuit, generating extreme heat and potentially igniting nearby flammable materials.
- Long-Term Risks: Even if a fire does not immediately occur, a compromised battery remains a significant hazard. Storing a damaged battery in a home or workshop can pose a continuous fire risk, endangering occupants and property.
- Who Might Be Affected: Individuals using Flex Power Tools Lithium-Ion Battery Pack FX0111, household members (including children and pets who might come into contact with the leaking battery), and anyone in the vicinity of a potential battery fire.
- Property Damage Potential: A battery fire, especially one involving lithium-ion technology, can rapidly spread, causing extensive damage to tools, vehicles, homes, and other personal property. The release of corrosive chemicals can also damage surfaces and materials.
What Consumers Should Do
Consumers who own a Flex Power Tools Lithium-Ion Battery Pack FX0111, particularly if they observe any signs of damage, leakage, swelling, or overheating, should take immediate action:
- Stop Use Immediately: Discontinue using the affected battery and any other batteries of the same model that show similar symptoms. Do not attempt to charge or continue using a damaged or leaking battery.
- Isolate and Secure: Carefully move the affected battery to a safe, non-combustible location away from flammable materials, children, and pets. If possible, place it in a fire-resistant container (e.g., a metal bucket filled with sand) outdoors. Wear gloves if handling a leaking battery to avoid skin contact.
- Do Not Dispose of in Regular Trash: Damaged lithium-ion batteries should not be discarded in household trash due to fire risks. Contact your local waste management facility for proper disposal instructions for hazardous materials.
- Check Your Product: Verify if you own a Flex Power Tools Lithium-Ion Battery Pack model FX0111 by inspecting the product label.
- Contact the Manufacturer (Again): Despite reported difficulties, try contacting Chervon Group NA (Flex Power Tools’ parent company) to report the incident and seek a resolution. Document all communications, including dates, names of representatives, and any reference numbers.
- Report to Safety Authorities: File a detailed report with the U.S. Consumer Product Safety Commission (CPSC) at SaferProducts.gov. This helps authorities track incidents and potentially initiate investigations or recalls.
- Prevention Measures: Regularly inspect all your power tool batteries for any signs of damage, deformation, leakage, or unusual heat during charging or use. Store batteries in a cool, dry place away from direct sunlight and extreme temperatures.
Manufacturer’s Response
As of the date of this report, the manufacturer’s official response to this specific incident report is unknown. The consumer’s account indicates multiple attempts to contact Flex Power Tools regarding the issue and a perceived lack of resolution or receipt of promised replacements.
