Smartphones, power banks, tablets, Bluetooth devices, and laptops have become essential parts of daily life. Over time, lithium-ion batteries naturally degrade due to repeated charging cycles, high temperatures, improper charging habits, and aging.
In many cases, degraded batteries begin to swell because gases form inside the battery. The swelling often occurs gradually and may go unnoticed, especially when the device is inside a protective cover.
Many people continue using devices with swollen batteries or store old electronic devices in drawers and cupboards. Lack of awareness about the warning signs can increase the risk of battery failure, overheating, device damage, and, in some cases, fire incidents.
This creates a growing consumer safety and e-waste management challenge.
