People in our communities are using e-scooters, hoverboards, and a wide range of other items that utilize lithium-ion batteries. Some of these products are assembled and shipped from overseas, in areas where safety standards may be insufficient for these devices. This increases the likelihood of thermal runaway, internal short circuits, or other malfunctions.
Things to look out for and safe practices to follow.
- Cracks in the battery's outer casing.
- Bulging of the battery.
- Never leave batteries on a charger for long periods. (If the battery is charged, remove it.)
- Ensure that you store and charge lithium-ion batteries in a cool area, avoiding hot environments and direct sunlight.
- Use the factory-provided charger for the battery.
- Avoid power strips or overloading outlets.
According to IFC 2021, the equipment and wiring code stipulates that each item must have regulations established for proper handling, charging, care, and whether it can be plugged into an extension cord or power strip. If this information cannot be verified for your specific item, it is advisable to plug it directly into a receptacle.
603.1.1 Equipment and Wiring.
-- All electrical equipment, wiring, devices, and appliances shall be tested; listed and labeled; and installed, used, and maintained in accordance with NFPA 70 and all instructions included as part of such listing.
What can be done?
Inform your community about the potential risks associated with lithium-ion batteries. Demonstrate what types of defects to look out for, ensure they are using the correct chargers, and advise them not to leave batteries charging for extended periods.
While most of the time these items are completely safe, they can also be extremely dangerous when proper care and maintenance are not done correctly.
