October 21, 2026 — A consumer has reported an incident involving an APC BR1500MS2 uninterruptible power supply (UPS) battery that reportedly overheated, filled their home with toxic fumes, and emitted a strong burning plastic smell. The incident occurred several weeks after the product was purchased online.
Product Details
Incident Overview
The consumer purchased the APC BR1500MS2 battery on eBay on May 15, 2026, and it was delivered on May 19, 2026. Several weeks after setting up the product in their home office, the consumer awoke to their entire 2-story house filled with the smell of burned plastic. The source of the alarming odor was identified as the backup battery, which had severely overheated. Upon touching the unit, the consumer experienced an immediate reflex to pull away due to the extreme heat. The product had to be unplugged to cool down before any further investigation could take place. The incident resulted in the release of toxic fumes from the burning plastic throughout the home.
Safety Concerns
This incident highlights several significant safety concerns associated with overheating electronic devices:
- Immediate Dangers: The primary immediate danger is the inhalation of toxic fumes from burning plastic. Such fumes can cause acute respiratory irritation, dizziness, nausea, and can be particularly harmful to individuals with pre-existing respiratory conditions, young children, and pets. The extreme heat reported also poses an immediate burn risk upon contact and indicates a serious potential for fire.
- Long-Term Risks: Prolonged exposure to toxic fumes, even at lower levels, can lead to long-term respiratory issues, neurological effects, and other health complications. A product overheating to this extent suggests a potential electrical malfunction that could lead to subsequent hazards if not addressed.
- Who Might Be Affected: All occupants of the home, including adults, children, and pets, are at risk from smoke inhalation and potential exposure to harmful chemicals released into the air. First responders entering the property could also be at risk if a fire had fully erupted.
- Property Damage Potential: An overheated battery, especially one emitting such intense heat and smoke, presents a significant fire hazard. A fire originating from such a device could rapidly spread, causing extensive smoke and fire damage to the home, its contents, and potentially adjacent properties.
What Consumers Should Do
Consumers who own an APC BR1500MS2 or any similar uninterruptible power supply should take the following precautions:
- Immediate Steps: If you detect a burning smell, excessive heat, or smoke coming from your UPS or any electronic device, immediately unplug it from the power source if it is safe to do so. Do not touch a hot device. Open windows and doors to ventilate the area and evacuate your home if the fumes are strong or you suspect a fire. Call 911 if there is any sign of fire or if you feel unwell.
- Check Your Product: Verify if you own the APC BR1500MS2 model. Look for the model number on the unit itself, typically on a label on the back or bottom.
- Prevention Measures: Ensure proper ventilation around your UPS and other electronic devices. Avoid placing them in enclosed spaces. Regularly inspect your devices for any signs of damage, swelling (especially batteries), or unusual odors. Do not ignore warning signs like strange smells or excessive heat.
- Reporting Procedures: If you experience a similar incident with this or any other consumer product, report it immediately to the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov. Your report helps identify hazardous products and can prevent further incidents.
