Fire Department Stresses Importance of Certified Products and Safe Charging Practices

In light of recent lithium-ion battery fire incidents in areas such as Mapo-gu, Seoul and Gyeonggi Province, extra caution is advised when using products powered by lithium-ion batteries, including electric scooters and electric bicycles.

According to the Sejong Fire Department on August 22, there have been a total of 40 lithium-ion battery fire incidents in the region over the past five years: 5 cases in 2021, 9 in 2022, 10 in 2023, 10 in 2024, and 6 cases as of August 2025.

Among these, fires involving electric scooters and electric bicycles accounted for 12 cases, representing 30% of the total and highlighting them as major risk factors. In particular, causes of these fires were identified as overheating during charging, the use of non-certified products, and leaving chargers connected for extended periods after the battery is fully charged.

Therefore, it is recommended to always verify and purchase KC-certified batteries and chargers, avoid using damaged batteries, keep batteries away from high temperatures and impacts, disconnect the charger immediately after full charging, and refrain from charging batteries in enclosed spaces such as entryways or hallways.

A representative from the Fire Department stated, "Lithium-ion battery products are essential items most commonly used in daily life, but even minor carelessness can lead to major fires," urging the public to strictly follow safety guidelines.
