4. Equipment Damage
A swollen battery can damage your device, causing problems such as bent screens, damaged ports and even cracked cases.
Part 3: What causes a swollen battery?
Battery swelling is caused by a chemical reaction within the battery. The main causes of this problem include:
1. Overcharging
Continuously charging your device can lead to a buildup of gas inside the battery, causing it to swell.
2. High temperatures
Heat is a major contributor to battery expansion. Charging a device at high temperatures, such as leaving it in a car on a sunny day, can cause the battery to swell.
3. Battery Life
Natural degradation of the battery as it ages can cause it to swell more easily. If the device’s battery is more than two years old, it may begin to show signs of wear and tear.
4. Poor quality batteries
Poor-quality batteries with fewer protective layers are more likely to swell. These batteries are less stable and are more likely to expand as they age.
5. Physical Damage
Dropping or mishandling the device may cause internal damage to the battery, which in turn may cause swelling.
Part 4: How to Recognize a Swollen Battery
Recognizing a swollen battery can be tricky, especially if it is located inside the device. You can check it by following the steps below:
1. Check the device casing
Check the device casing for any unusual gaps, bumps, or raised areas that weren’t there before.
2. Touch the surface
Gently press or touch the back cover or screen of the device. A slight bulge may indicate internal expansion.
3. Monitor Device Performance
A swollen battery often leads to performance issues such as faster battery drain, overheating, or unexpected shutdown.
4. Listen to the Sound
In rare cases, you may hear a slight hissing sound as gas builds up inside the battery causing it to expand.
Part 5: How to Safely Remove an Expanded Battery
Removing an expanded battery requires extra care. When handling an expanded battery, be sure to take appropriate safety measures to avoid further damage or injury. Always wear protective gloves and safety glasses. If you are unsure how to proceed, it is best to take the device to a certified technician who will remove the battery and handle it.
Conclusion
A swollen battery is not only an inconvenience, it can also pose a significant risk to your safety and your equipment. By always watching for signs of a swollen battery, understanding the cause, and taking preventative measures, you can protect yourself and your equipment from potential harm. If you notice any signs of a swollen battery, be sure to act quickly and responsibly to minimize the risk.
