Cell phone with a bloated battery explodes while being repaired, injuring technician in Goiás; watch video
A technician repairing a cell phone was hurt when the phone exploded at a repair shop in Aparecida de Goiânia (GO). The incident was captured on security camera, showing the battery catching fire as the technician was working on the device. The explosion caused the technician to fall from the chair, frightening other employees.
Watch the video of the occasion:
The individual sustained injuries from shrapnel and flames, resulting in burns on the skin, face, and outer eye area as reported by TV Anhanguera.
He was transferred to a specialized hospital after the accident and mentioned experiencing “white” vision. Medical tests later confirmed no internal eye injuries. He is currently recovering and using eye drops as part of his treatment.
Mobile phone had an enlarged battery
The device was sent for maintenance due to the battery displaying obvious signs of swelling, as per technical support.
The explosion occurred as soon as the technicians began the process of replacing the faulty part.
Deformed lithium-ion batteries can build up internal gases and become pressurized. If the battery structure is compromised during device opening, such as through drilling or damage, a very quick chemical reaction may occur, leading to the release of heat, smoke, and flames.
Preventing a cell phone battery from exploding.
While rare, taking precautions can significantly lower the chance of accidents related to explosions. It is important not to disregard any warning signs from the device’s battery, such as the screen or back cover starting to detach or bulge slightly. If this occurs, it is recommended to stop using the device and promptly seek professional help.
It’s crucial to monitor overheating in your mobile device. If it is heating up more than usual, particularly during charging, it is advisable to seek a technical assessment.
Suggestions also include refraining from charging the device immediately after heavy use or sun exposure, allowing it to cool down before plugging it in, and avoiding unnecessary overnight charging.
What leads to this type of explosion?
Most smartphones utilize lithium ion batteries, which can swell due to factors like aging, impacts, defects during production, or prolonged heat exposure.
The battery’s structure becomes compromised, and if there is any drilling or short circuit, it can lead to thermal leakage, resulting in a rapid temperature increase and potential fire or explosion.
Experts advise against using a cell phone with a damaged battery and caution against attempting to replace it without the proper tools and care to prevent accidents.
