Product Details
Product: Hart Us Pat. 7,554,290
Incident Overview
On August 16, 2026, an alarming incident occurred where a Hart tools battery pack reportedly exploded in the middle of the night. According to the report, the battery pack was connected to its charger cable but was not plugged into a power outlet at the time of the explosion. The unit had been resting in this state for several days, untouched, before it spontaneously combusted. The explosion was powerful enough to almost cause a house fire, highlighting the severe danger posed by such malfunctions.
Safety Concerns
The explosion of a battery pack, especially one that was not actively charging or in use, raises a multitude of serious safety concerns:
- Immediate Dangers: The primary and most immediate danger is fire. Battery explosions often involve intense heat, flames, smoke, and can project shrapnel. This poses an immediate risk of severe burns, smoke inhalation, and traumatic injuries from the force of the explosion.
- Long-Term Risks: If a fire were to fully ignite, the long-term risks include extensive property damage, structural compromise to the home, loss of personal belongings, and potential for carbon monoxide poisoning if not properly ventilated. Even a small fire can lead to significant smoke damage requiring extensive remediation.
- Who Might Be Affected: Anyone in the household, including children, pets, and adults, is at risk of injury or death from fire or explosion. Neighbors could also be affected if a house fire spreads.
- Property Damage Potential: The incident report explicitly states the explosion almost caused a house fire, indicating a high potential for significant property damage. Battery fires can be particularly difficult to extinguish and can spread rapidly, consuming flammable materials in their vicinity. The force of an explosion can also cause structural damage or break windows.
What Consumers Should Do
Consumers who own Hart brand tools, particularly battery packs, should take the following precautions:
- Immediately Stop Use: If you own a Hart Us Pat. 7,554,290 battery pack, discontinue its use immediately. Do not attempt to charge or use it.
- Safe Storage: If you must store the battery, do so in a cool, dry place, away from flammable materials and out of direct sunlight. Store it in a non-combustible container, if possible, and away from living areas.
- Inspect Your Products: Carefully inspect all your Hart battery packs for any signs of damage, swelling, overheating, or unusual odors. If you notice any of these indicators, stop using the battery immediately and follow safe disposal guidelines.
- Supervise Charging: Always supervise batteries while they are charging. Do not leave charging batteries unattended for extended periods or overnight. Only use chargers specifically designed for your battery pack.
- Report Incidents: If you experience an incident involving a Hart tool battery or any other consumer product, report it immediately to the U.S. Consumer Product Safety Commission (CPSC) at www.SaferProducts.gov. This information is vital for identifying trends and initiating recalls.
- Contact Manufacturer: Consider contacting Walmart Stores Inc., the manufacturer, directly to report the incident and inquire about potential remedies or replacement programs.
