Lithium-ion batteries have become widely used in various electronic devices that people use in their daily lives, including smartphones, computers, tablets, gaming consoles, electric skateboards, and more. But the California Fire Department reminds the public that improper charging can potentially lead to fires or small explosions.
To raise public awareness and coincide with Fire Prevention Week from October 5th to 11th, the California Fire Department (Cal Fire) and the National Fire Protection Association (NFPA) have launched a campaign promoting “Safe Charging” and “Preventing Fires”. They aim to remind people to be cautious of the potential risks associated with lithium-ion batteries in their homes.
When a battery exhibits abnormal heat, emits strange odors, makes unusual sounds, deforms, or leaks, these are warning signs of danger. If a lithium-ion battery product smokes or catches fire, individuals should immediately dial 911.
The California Fire Department states that improper charging methods with any device containing lithium-ion batteries can potentially lead to fires. This includes using the wrong charger or charging cable, using damaged chargers, overcharging, and charging on surfaces like beds.
The department further emphasizes, “Not all charging cables are safe, it is best to use manufacturer-approved charging cables or those that come with the device. This ensures proper charging and reduces the risk of fires.”
Incidents of lithium-ion batteries catching fire or overheating have been ongoing. In the past five years, the U.S. Consumer Product Safety Commission has received thousands of reports annually regarding lithium-ion batteries catching fire or overheating. California has experienced several accidents caused by improper charging in the past.
In March of this year, a lithium-ion battery fire incident occurred in an apartment in Woodland, California, in the middle of the night. This incident resulted in eight residents being displaced and one firefighter being injured. The fire was caused by a lithium-ion battery from an electric skateboard charging inside the apartment.
California Fire Department Chief Daniel Berlant commented, “This year’s focus is on purchasing, charging, and recycling lithium-ion batteries in a safe manner.”
According to NFPA data, most devices utilizing lithium-ion batteries operate without incidents. However, in recent years, there has been a gradual increase in fires and explosion incidents related to lithium-ion batteries, with human error being the leading cause. Below are some safety guidelines provided by NFPA:
1) When purchasing products with lithium-ion batteries, ensure that the product has been certified by nationally recognized testing agencies. Many products sold online or in stores may not meet safety standards, increasing the risk of fires.
2) Use the charger and cables that come with the product and follow the instructions manual;
3) When replacing chargers or cables, choose products from the same brand or approved alternatives;
4) During charging, always place electronic devices on a firm surface (like a desk), never charge on pillows, beds, or sofas as lithium-ion batteries can overheat and cause fires;
5) Unplug the charger immediately after the device is fully charged, do not leave electronic products charging overnight or all day;
6) Dispose of lithium-ion batteries or devices at a safe battery recycling site, never throw them directly into the trash to avoid fire hazards. ◇
