A new fire-tracking system launched in Massachusetts has identified 50 incidents involving lithium-ion batteries in just six months, according to the state’s Department of Fire Services. Among these cases, six fires were specifically linked to power tool batteries, such as cordless drills and similar equipment.

Officials say the findings highlight growing concerns over the safety of lithium-ion batteries used across a wide range of consumer and industrial products. While much public attention has focused on e-bikes and scooters, the data suggests that power tools are also a notable source of fire risk.

Fire investigators point out that power tool batteries face unique challenges: they are often subjected to heavy loads, frequent vibration, and tough job-site conditions. These stresses can damage battery cells, increase overheating risks, and, in extreme cases, trigger thermal runaway — a chain reaction that can lead to fire or explosion.

The Department of Fire Services urged consumers and workers to take precautions, including:

• Using only certified or manufacturer-approved batteries and chargers

• Avoiding overcharging or leaving batteries unattended while charging

• Inspecting batteries regularly for swelling, cracks, or heat damage

• Keeping appropriate fire extinguishers nearby in garages, workshops, or construction areas

Massachusetts fire officials said the tracking tool will continue collecting statewide data to better understand battery-related fire patterns. They hope the system can serve as a model for other states, as lithium-ion batteries become increasingly common in both households and workplaces.
